GETTING STARTED

UNITE SYSTEM
Unite is a digital wireless communication system that allows people to communicate and interact with each other in a wide range of applications such as guided tours, wireless presentations, assistive listening and blind coverage, education, interpretation and language distribution. This wireless transmission platform in DECT standard means the system can be used without certification and licence fees. The frequencies, that are region-dependent, do not need to be managed as the system itself automatically controls robust and encrypted transmission. This allows up to 32 groups to be integrated in parallel, and its wide operating range and long operating time offer completely stable transmission conditions.
Product Overview
The Unite system consists of the following elements:
DIGITAL TRANSMITTERS
The Unite digital transmitters are used in conjunction with bodypack receivers. They can also be used as a wireless microphone system, as well as for multilingual interpretation and assistive listening applications.
Unite TP

UNITE SYSTEM

SYSTEM INFORMATION
DECT Technology
Unite is based upon DECT (Digital Enhanced Cordless Telecommunications) technology, an international standard for telecommunications using wireless technology, and known in particular for its use with cordless telephones. Wireless technology enables a device to communicate with a central processing unit. The modern, future-proof transmission platform in DECT standard means the system can be used worldwide without registration and free of charge. In addition, DECT systems offer outstanding security as for each connection the receiver is required to register with the transmitter using a confidential code. Below 2.4 GHz, DECT uses different frequencies to WLAN, Bluetooth®, etc. and therefore causes no interference with these networks.
Operating Range
Unite is able to bridge very great distances between the various device types. Peak values up to 300 m can be achieved in open areas. There are various influencing factors inside buildings. Operating range is restricted by the number and composition of walls, ceilings and floors. Performance is inevitably restricted as a result of absorption and reflection of the high frequency range. For example, reinforced concrete absorbs frequencies to a certain extent, whereas a metal-clad ceiling reflects them. A further influencing factor is the number of active DECT wireless connections conditional upon the frequency band available in each region. In Europe, for example, a maximum of 120 channels can be in use, whereas the maximum for the American market is 60 channels. The total number of connected devices can be much higher than these key indicators, however, since they relate only to the number of simultaneously used DECT radio connections actively occupying a channel.

SYSTEM INFORMATION

Actual restriction of the system is generally only to be expected when all influencing factors occur at once. For example: in one area of a building, there are 70 simultaneously active DECT telephones; in this same part of the building there are 32 Unite groups, the transmitters of which are attempting to reach their groups through several walls simultaneously. The walls are made of reinforced concrete and all ceilings are metalclad.

Automatic Frequency and Group Management

A further benefit of this technology is automatic frequency management. This means you need not worry about frequencies, as the system itself controls transmission and adjusts automatically for secure transmission. It recognises the availability and allocation of frequencies and adjusts dynamically and automatically. Interference signals are identified at an early stage, enabling the system to react immediately.

Without the knowledge of the user and/or listener, it switches frequency to ensure uninterrupted operation.

The system also identifies all active wireless connections and adapts these dynamically so that individual groups do not interfere with each other. This means Unite can be used in parallel by up to 32 groups.

A high operating range and long operating time create stable conditions for transmission.

SYSTEM INFORMATION

For other countries: please contact Televic Conference.
All devices are supplied with the group ID 256 and fixed audio encryption allowing quick and easy setup. This allows for quick and easy initial use.
The group ID identifies devices that can be placed in a virtual group. For example, all devices within a building, a tour group or a conference room. The transmitter will only transmit the audio signal to a channel with a predefined channel name. If there are several transmitters in a group, the channel for the respective transmitter can be selected on the receiver. You will need to establish a new pairing if you require several device groups or secure audio transmission that cannot be intercepted by another group using Unite devices. The factory preset group ID is 256. If you want to set a group ID between 1 and 255, please read the sections below or refer to the Pairing section of your device(s) in this manual.
Group ID
The group ID refers to devices that can be combined to a virtual group. For example, all devices of a building, a travel group or a conference room.
Using with Group ID 150-256
By default, the transmitters and receivers are supplied with the group ID 256. A common factory-set audio encryption key, which cannot be changed, is used for the group ID range of 150 to 256. The audio encryption key ensures additional security against unauthorised listening during the wireless transmission. Due to the factory-set audio encryption key the devices within the group ID range of 150 to 256 can connect to each other without pairing via the charger. In this case receivers can connect to transmitters via the dynamic channel search.

SYSTEM INFORMATION

Example: Via the dynamic channel search, a receiver which is set to the group ID 160 will find all transmitters which are active and also set to the group ID 160. The receiver will not find transmitters beyond the set ID range of 160.
When using several transmitters (e.g. Unite AP4 and several Unite TP) with the same group ID at the same time, make sure that the individual channel names differ from each other! Otherwise this can cause connection problems with the receivers!
Using with Group ID 1-149
If several receivers are to be divided into different groups with an individual encryption, for each group an individual group ID between 1 and 149 can be assigned. A separate audio encryption key is generated for an individual group ID in order to ensure additional security against unauthorized listening during the wireless transmission. This audio encryption key is generated during the pairing process, stored in the charger and transmitted from the charger to the transmitter and receiver, along with the channel name and group ID. The receivers can only connect to a transmitter with which they have been paired via the charger. If the group ID is subsequently set manually on a receiver which has not been paired, no connection can be established to the transmitter with the encrypted group ID, because the receiver does not have the audio encryption key.
Encryption
The audio data is always encrypted with an AES-256 code to ensure a secure transmission against unauthorized listening.
The required key will be generated within the charging unit itself and transmitted to the transmitters and receivers during the pairing process.

SYSTEM INFORMATION

As the encryption code is not transmitted wirelessly, the system is better protected against unauthorized listening. Should the receiver receive a differently encrypted audio signal for which no encryption code has been saved, the received audio signal will be muted. The receiver display will also alternate between showing the relevant channel name and the "KEY!" error message.
The encryption of the audio signal is explained schematically in the "Encryption" diagram below.

The group IDs in the range of 150 to 256 uses a factory-defined key that cannot be changed. You can use this group ID for a system without pairing.
The transmitter and receiver can only communicate if the settings for group ID, channel name and encryption match. Transmitters cannot communicate with receivers that do not have the same pairing information.
If you need a specific encryption key, you need to use a group ID between the range of 1 and 149. Refer to the Pairing section of your device to change the group ID.

These safety instructions are applicable to the Unite TP and Unite TH transmitters, as well as to the Unite RP and Unite RP-T receivers. Genera:l
Protect the transmitter/receiver from moisture and sudden impacts. You could either injure yourself or others or damage the transmitter/receiver. Troubleshooting and Servicing: Never open the device yourself. Leave all service work to authorised expert personnel. Maintenance: Only clean the equipment with a slightly damp or dry cloth. Never use solvents as these damage the surface. Rechargeable Battery:
The transmitter/receiver is operated with the following battery type: BAT-3707, lithium-ion, 3.7 V, 1.88 Ah, 6.96 Wh.
Use only a USB 2.0/3.0 compliant 5V power supply to charge the battery pack via the integrated USB type-C port (power consumption is max. 500 mA).

SAFETY INSTRUCTIONS ABOUT THE DEVICES

High temperatures, particularly in association with a high charging status, result in irreversible damage of the battery pack.
If you are not intending to use the battery for an extended period or are planning to put it into storage, it is advisable to lower the battery's charging level to around 50% and to store it at temperatures of maximum 30 °C.
In order to ensure safe transport by land, sea and air, the battery pack used for the bodypack transmitter is tested according to the UN 38.3 transport regulation for lithium-ion batteries.
Misuse or improper use could damage the battery pack. In extreme cases, there is a risk of explosion, heat, fire, smoke or gas.
Never expose the battery pack to excessive heat such as sunshine, fire or the like.
Do not expose the battery pack to mechanical shock.
Charge the battery pack before initial use.
Use the specified chargers for charging the battery pack.
Avoid complete draining of the battery. This could damage the battery and shorten its service life.
If you do not use the transmitter for several months, the batteries should be charged at least twice a year to prevent deterioration in performance due to self-discharge.
Clean the charging contacts of the transmitter with a clean dry cloth, if they become dirty.
Do not short-circuit the battery.
The charging contacts could cause property damage, injuries or fire damage if they come into contact with conductive materials such as jewellery, keys or chains. This can lead to a closed electric circuit and, therefore, to the material overheating. To avoid this kind of unintentional electric circuit, the charging contacts must be handled with care. This is especially important if the transmitter is transported in a bag or another container containing other metallic objects.
Humidity / Heat Sources: Keep the battery pack clean and dry. Never expose the device to rain or high humidity. Do not install it in the immediate vicinity of swimming pools, shower facilities, damp basements or other areas with unusually high air humidity.

SAFETY INSTRUCTIONS ABOUT THE DEVICES

Never place objects filled with water (e.g. vases or drinking glasses) on the device. Liquids in the devices may cause a short circuit.
Never install or operate the device in the immediate vicinity of radiators, lighting systems or other heat-generating devices.
Volume: When using headphones/headsets, make sure that the volume is set to minimum. Adjust the volume only after putting on the headphones/ headset. Too high volumes and too long listening times can damage your hearing. Hearing damage always represents an irreversible impairment of hearing.
Always pay attention to the volume. As a rule of thumb, the higher the volume, the shorter the listening time. By law, the maximum allowed value is 85 dB at a maximum listening time of 8 hours.
Temporary symptoms that you have been exposed to loud noise are: ringing or whistling in the ears
high tones can no longer be perceived.
Unite TH Handheld Transmitter: Do not blow into the microphone. In a condenser microphone this could damage the transformer. It is preferable to carry out a speech trial.
Unite TP Bodypack Transmitter: Clip-on microphones are often very compact. If they are accidentally swallowed there is a risk of choking. Always keep this type of microphone away from small children.
Unite RP / RP-T Bodypack Receiver: The supplied strap is only used for wearing the device around the neck. If it is not used correctly, the risk of strangulation may occur.

CREATING A NEW PAIRING ON THE TRANSMITTERS

CREATING A NEW PAIRING WITH THE CHARGER
The transmitter and receiver must be paired to enable them to communicate with one another. The code required for this is generated in the charger* and transmitted during the pairing process to both transmitter and receiver.
* Creating a new pairing with a Unite charger is only possible with the following models: Unite CC-28/2, Unite CC-36/2, Unite CR-12P, Unite CDS-4/2 and Unite CDD-8/4. It is not possible to use the Unite DS-4/2 charger for this purpose.
For group ID 256 only, a factory preset code is used that cannot be changed. You can use this group ID for a system without pairing.
Changing the Group ID with a Charging Unit
To establish a pairing with a charging unit, please proceed as described below:

CREATING A NEW PAIRING WITH THE CHARGER

1. On the transmitter, set the group ID you wish to use for pairing.
2. Insert one transmitter only in the charger. If more than one transmitter is used in the charger, pairing will not start and the charger's status indicator (2) will show an error message (see table 2). Alternatively you can connect the transmitter using a USB cable connected to the charger's USB port.
3. Insert one or more receivers to be paired with the transmitter into the charger's charging compartment. You can also connect another receiver to the charger using the USB port. Remove all receivers that are not to be paired. Should no receiver be connected to the charger, pairing information is stored in the charger only. This is used for later pairing without connecting the transmitter to the charger.
4. To transmit information from the transmitter to the receivers in the charging compartments and to the charger itself for future pairings, hold down the "Pair/Reset" button (1) on the charger for more than 2 seconds. The "Status" light (2) will flash yellow for a few seconds if the pairing is successful. The status light will then remain yellow because the pairing information is now also saved in the charger.
5. If you wish to pair other receivers, remove the transmitter and all receivers from the charger, switch to "Pair & Charge" (3) and insert the unpaired receivers into the charger. The pairing information will be saved immediately in the unpaired receivers. The status light on the receiver will rapidly flash yellow while this happens.
6. If you have no further devices to pair, switch the charger to "Charge only" (3).
7. Switch on the transmitter and one receiver to check that they have both been paired successfully. After a few seconds the status light on the receiver will light up green and show the channel name of the transmitter.
8. To delete pairing information stored in the charger, hold the "Copy/Reset" button down for more than 5 seconds. The status light (2) will then remain permanently green.
9. In pairing mode (switch to "Pair & Charge"), the status light (2) on the charger will display the following information:

When not in use, switch off the device and disconnect the power plug from the power socket. Make sure that you do not pull on the cable, but on the power plug.

MAINS CONNECTIONS

ESTABLISHING PAIRING
Transmitters and receivers must be paired so that they can communicate with each other. For a successful pairing the channel name, group ID and audio encryption key are required. The required audio encryption key is generated in the Unite CC cockpit case or via the Unite Manager software. During the pairing process, it is first stored on the cockpit case and then it is transferred to the transmitter and receiver in the charging compartments. In this context, please also note the position of the switch on the cockpit case. The switch must be set to the "Pair & Charge" position so that the pairing information can be transmitted from the Unite CC to the transmitters and receivers. There are three different ways to pair the Unite transmitters with receivers:
1. Via an individual charger. 2. Using the Unite Manager Software on a PC. 3. Via dynamic channel search.
Group ID
The group ID refers to devices that can be combined to a virtual group. For example, all devices of a building, a travel group or a conference room.
Using with Group ID 150-256
By default, the transmitters and receivers are supplied with the group ID 256. A common factory-set audio encryption key, which cannot be changed, is used for the group ID range of 150 to 256. The audio encryption key ensures additional security against unauthorised listening during the wireless transmission. Due to the factory-set audio encryption key the devices within the group ID range of 150 to 256 can connect to each other without pairing via the charger. In this case receivers can connect to transmitters via the dynamic channel search.

ESTABLISHING PAIRING

Example: Via the dynamic channel search, a receiver which is set to the group ID 160 will find all transmitters which are active and also set to the group ID 160. The receiver will not find transmitters beyond the set ID range of 160.
When using several transmitters (e.g. Unite AP4 and several Unite TP) with the same group ID at the same time, make sure that the individual channel names differ from each other! Otherwise this can cause connection problems with the receivers!
Using with Group ID 1-149
If several receivers are to be divided into different groups with an individual encryption, for each group an individual group ID between 1 and 149 can be assigned. A separate audio encryption key is generated for an individual group ID in order to ensure additional security against unauthorized listening during the wireless transmission. This audio encryption key is generated during the pairing process, stored in the charger and transmitted from the charger to the transmitter and receiver, along with the channel name and group ID. The receivers can only connect to a transmitter with which they have been paired via the charger. If the group ID is subsequently set manually on a receiver which has not been paired, no connection can be established to the transmitter with the encrypted group ID, because the receiver does not have the audio encryption key.
Changing the Group ID with a Charging Unit
To establish a pairing with a charging unit, please proceed as described below:

AUTOMATIC FIRMWARE UPDATE
By using the Unite Cockpit Rack/Case you can upload firmware updates to Unite transmitters/receivers. With the current factory settings, the Unite Cockpit Rack/Case will automatically update the firmware of the Unite transmitters/receivers during the first charging process. Just insert the transmitters/receivers into the charging compartments. During the firmware update, the status indicator light of the Unite transmitters/receivers will illuminate red. This process will take approx. 5 minutes. Should the process take longer than 10 minutes, turn the Unite Cockpit Rack/Case off and on again. The update process will then restart.
Please note that after a successful update to a new firmware version, the Unite transmitters/receivers are no longer compatible with older firmware versions.

AUTOMATIC FIRMWARE UPDATE

CONDITIONING THE BATTERY
In order to achieve the maximum capacity of the battery, we recommend discharging the transmitters/receivers completely to carry out a complete charging cycle afterwards. This also increases the accuracy of the battery indicator on the display of the Unite transmitters/receivers.

CONDITIONING THE BATTERY

SERVICE MODE
For maximum operational reliability, the Unite Cockpit Case features a so-called service mode. If the device is disconnected from the mains within 45 seconds after being switched on (e.g. by accidental switching off), the device will boot in a safety mode and check itself. If this service mode is activated automatically (after booting unsuccessfully), the system will return to its usual operating mode after approx. 3 minutes.

Transmitters and receivers must be paired so that they can communicate with each other. For a successful pairing the channel name, group ID and audio encryption key are required. The required audio encryption key is generated in the Unite CDD-8/4 and Unite CDS-4/2 chargers via the Unite Manager software. During the pairing process, it is first stored on the cockpit case and then it is transferred to the transmitter and receiver in the charging compartments. In this context, please also note the position of the switch on the cockpit rack. The switch must be set to the "Pair & Charge" position so that the pairing information can be transmitted from the Unite CR to the transmitters and receivers. There are three different ways to pair the Unite transmitters with receivers:
1. Via an individual charger. 2. Using the Unite Manager Software on a PC. 3. Via dynamic channel search.
Group ID
The group ID refers to devices that can be combined to a virtual group. For example, all devices of a building, a travel group or a conference room.
Using with Group ID 150-256
By default, the transmitters and receivers are supplied with the group ID 256. A common factory-set audio encryption key, which cannot be changed, is used for the group ID range of 150 to 256. The audio encryption key ensures additional security against unauthorised listening during the wireless transmission. Due to the factory-set audio encryption key the devices within the group ID range of 150 to 256 can connect to each other without pairing via the charger. In this case receivers can connect to transmitters via the dynamic channel search.

ESTABLISHING PAIRING

Example: Via the dynamic channel search, a receiver which is set to the group ID 160 will find all transmitters which are active and also set to the group ID 160. The receiver will not find transmitters beyond the set ID range of 160.
When using several transmitters (e.g. Unite AP4 and several Unite TP) with the same group ID at the same time, make sure that the individual channel names differ from each other! Otherwise this can cause connection problems with the receivers!
Using with Group ID 1-149
If several receivers are to be divided into different groups with an individual encryption, for each group an individual group ID between 1 and 149 can be assigned. A separate audio encryption key is generated for an individual group ID in order to ensure additional security against unauthorized listening during the wireless transmission. This audio encryption key is generated during the pairing process, stored in the charger and transmitted from the charger to the transmitter and receiver, along with the channel name and group ID. The receivers can only connect to a transmitter with which they have been paired via the charger. If the group ID is subsequently set manually on a receiver which has not been paired, no connection can be established to the transmitter with the encrypted group ID, because the receiver does not have the audio encryption key.
Change the Group ID
In order to perform a pairing with an individual charger, proceed as described in the following: 1. Set the desired group ID on the transmitter you want to use for pairing (see the "Pairing" section of "Pairing" or "Pairing" in this manual for more information.

ESTABLISHING PAIRING

2. Insert only one transmitter into the charging compartment of the charger. If multiple transmitters are inserted, the pairing will not start and the status indicator (5) on the charger will display an error (see table below). Further transmitters must be configured as sub-master so that they can be paired with a transmitter configured as a master. Furthermore, you can connect another transmitter / receiver to the USB port (5) on the charger when using a USB cable type C.
3. Insert one or more receivers into the charging compartments of the charger to be paired with the transmitter. You can also connect another receiver to the charger using the USB port (10). Remove all receivers that should not be paired. If there is no receiver in the charging compartments, the pairing information is stored in the charger. This is used for later pairing without connecting the transmitter to the charger.
4. In order to transfer the pairing information from the transmitter to the receivers in the slots and to the charger itself for future pairing, press and hold the "Pair/Reset" button (4) on the charger for more than 2 seconds. When the "Pairing Status" indicator (5) flashes yellow, release the button to perform a pairing. Mobile devices that are now being paired indicate this via a status indicator that illuminates yellow. After successful pairing the "Pairing Status" indicator (5) will permanently illuminate green to display that the pairing information is now also stored in the charger.
5. If you want to pair other receivers, remove the transmitter (Master) and all receivers from the charger and press the "Auto Pair" button (6) once. The "Pairing Status" indicator (5) will illuminate yellow. Insert the receivers that are not yet paired into the charger. The pairing information is immediately stored in these receivers. The "Pairing Status" indicator (5) flashes yellow and displays the active pairing process. On the devices that have received the pairing information, the status indicator lights yellow for about 10 seconds. As soon as the "Pairing Status" indicator (5) is permanently lit yellow, the pairing process is complete and you can remove the receivers from the charging compartments.
In order to end the "Auto Pair" function, press the "Auto Pair" button (6) once. The "Pairing Status" indicator (5) will illuminate green to indicate that the pairing information is stored in the charger.
The "Auto Pair" function is not possible, when no pairing information is stored in the charger. In this case the "Pairing Status" indicator (5) flashes red five times.

ESTABLISHING PAIRING

6. Switch on the transmitter and a receiver to check whether the pairing was successful. When the devices are successfully paired, the status indicator of both devices will illuminate green and the receiver should display the channel name of the transmitter.
7. In order to delete the stored pairing information, press the "Pair/Reset" button (6) until the "Pairing Status" indicator (5) first flashes yellow and the goes out.

PAIRING
Creating a Pairing
In order to communicate with each other, the transmitter and receivers must have the same group ID, encryption key and channel name. Only then they can communicate with each other. There will be no communication with receivers that do not have the same pairing information. This is illustrated in the figure below:

The required audio encryption key is generated in the Unite Charger (Unite CC, CR, CDD-8/4 or CDS-4/2) or via the Unite Manager software. During the pairing process, it is first stored on the charger, and then it is transferred to the transmitter and receiver in the charging compartments. In this context, please also note the position of the switch on the charger. The switch must be set to the "Pair & Charge" position so that the pairing information can be transmitted from the Unite charger to the transmitters and receivers. There are three different ways to pair Unite transmitters with receivers:
1. Via an individual charger.
Pairing is possible with the Unite CC, CR, CDD-8/4 and CDS-4/2 only.

PAIRING

114

2. Using the Unite Manager Software on a PC. 3. Via dynamic channel search.
Encryption
The audio data is always encrypted with an AES-256 code to ensure a secure transmission against unauthorized listening.
The required key will be generated within the charging unit itself and transmitted to the transmitters and receivers during the pairing process. As the encryption code is not transmitted wirelessly, the system is better protected against unauthorized listening. Should the receiver receive a differently encrypted audio signal for which no encryption code has been saved, the received audio signal will be muted. The receiver display will also alternate between showing the relevant channel name and the "KEY!" error message. The encryption of the audio signal is explained schematically in the "Encryption" diagram below.

The group IDs in the range of 150 to 256 uses a factory-defined key that cannot be changed. You can use this group ID for a system without pairing.

PAIRING

115

The transmitter and receiver can only communicate if the settings for group ID, channel name and encryption match. Transmitters cannot communicate with receivers that do not have the same pairing information.
If you need a specific encryption key, you need to use a group ID between the range of 1 and 149. Refer to the Pairing section of your device to change the group ID.
Group ID
The group ID refers to devices that can be combined to a virtual group. For example, all devices of a building, a travel group or a conference room.
Using with Group ID 150-256
By default, the transmitters and receivers are supplied with the group ID 256. A common factory-set audio encryption key, which cannot be changed, is used for the group ID range of 150 to 256. The audio encryption key ensures additional security against unauthorised listening during the wireless transmission. Due to the factory-set audio encryption key the devices within the group ID range of 150 to 256 can connect to each other without pairing via the charger. In this case receivers can connect to transmitters via the dynamic channel search. Example: Via the dynamic channel search, a receiver which is set to the group ID 160 will find all transmitters which are active and also set to the group ID 160. The receiver will not find transmitters beyond the set ID range of 160.

PAIRING

116

When using several transmitters (e.g. Unite AP4 and several Unite TP) with the same group ID at the same time, make sure that the individual channel names differ from each other! Otherwise this can cause connection problems with the receivers!
Using with Group ID 1-149
If several receivers are to be divided into different groups with an individual encryption, for each group an individual group ID between 1 and 149 can be assigned. A separate audio encryption key is generated for an individual group ID in order to ensure additional security against unauthorized listening during the wireless transmission. This audio encryption key is generated during the pairing process, stored in the charger and transmitted from the charger to the transmitter and receiver, along with the channel name and group ID. The receivers can only connect to a transmitter with which they have been paired via the charger. If the group ID is subsequently set manually on a receiver which has not been paired, no connection can be established to the transmitter with the encrypted group ID, because the receiver does not have the audio encryption key.
Changing the Group ID
1. Press and hold the menu button for 2 seconds to activate the main menu. 2. Use the multifunction button to select "System" from the menu. 3. Press the menu button to open the required submenu. 4. Use the multifunction button to select the "Group ID" submenu. 5. Press the menu button to set an group ID. 6. Use the multifunction button to select the desired group ID.

PAIRING

117

7. Press the menu button to confirm the selected group ID.
Make sure to select the same group ID for all devices of a desired group. Only devices that have the same group ID can communicate with each other. Transmitters with other group IDs are hidden. See the following diagram.

PAIRING

118

6. Use the multifunction button to scroll through the characters. When the desired character appears, confirm using the menu button. You can input max. five characters.
As soon as you select the configured transmitter on the receiver, the defined name will be displayed on the receiver's display.

USING AS A SUB-MASTER
The Unite transmitter can be configured in a virtual device mode (Sub-Master). This allows up to two additional speakers to be integrated into a device group. In the Sub-Master mode, the transmitter can set up an exclusive connection to a Master device. In one group, a maximum of two Sub-Masters can be active and connected to one Master device. The connection between a Sub-Master and a Master device is technically the same as the connection between a Unite RP-T with activated "Talkback" function and a "Master". The difference is that the connection between a Unite RP-T and a Master is temporary, while the connection between a Sub-Master and a Master is permanent. In this case the audio channel is permanently open, but it can be muted by pressing the "Mute" button on the Sub-Master. In addition, there are of course still possibilities to connect external audio sources to the Sub-Master. All audio signals of the Sub-Master are distributed via the Master (Broadcast) and can be routed to the Master. These options can be found in the Master menu at "Talkback" --> "Audio Routing". Examples of up to 3 open microphones in the following device combinations:
1 x Master + 2 x Sub-Master 1 x Master + 2 x RP-T (Talkback ) 1 x Master + 1 x Sub-Master + 1 x RP-T (Talkback)
Configuring a Sub-Master
In order to configure the Unite transmitter as a Sub-Master, proceed as described below: 1. Use the On/Off and menu button to access the menu "System" --> "Device Mode".
2. Select the Sub-Master option.
3. Confirm the selected option with the On/Off and menu button.
4. Restart the transmitter by pressing the On/Off and menu button.
5. The transmitter reconfigures itself. This can take 1 - 2 minutes.
6. You can reconfigure the device as "Master" at any time.

HANDLING

130

GENERAL OPERATION
Before using the handheld transmitter for the first time, you must charge the built-in battery. Please use an appropriate Unite charger or the USB connection.
Switch on the transmitter by pressing the on/off button (4). In order to establish an audio connection between a transmitter and one or more receivers, all devices must be paired together. See the "Pairing" section for more information. All devices are supplied with the group ID 256 and fixed audio encryption allowing quick and easy initial use. This allows a fast and easy first use, since there is no pairing required for the open group ID range between 150 and 256. The transmitter will only transmit the audio signal on a channel with a predefined channel name. If there are several transmitters in a group between 150 and 256, the channel for the respective transmitter can be selected on the receiver (see the "Set the Channel Name" paragraph in the "Pairing" section for more information).
For more details about the menu, please read the Menu Items section of this manual.

GENERAL OPERATION

131

MICROPHONE GAIN AND NOISE SUPPRESSION
The Unite TH handheld transmitter provides various options to adjust the microphone gain and noise suppression automatically or manually. These options are enabled by an integrated digital signal processor (DSP). You will find the settings of these two DSP effects in the menu at "Audio" > "Input Effects". At the factory the "ALC" (Automatic Level Control) and "Noise Canceller" are activated.
If the "ALC" function is activated, the device performs an adjustment of the microphone gain to ensure that the signal is as evenly loud as possible. The result is a natural compression effect the integrated digital signal processor (DSP) responds to the volume of the incoming signal and automatically increases the volume of quiet signals while limiting loud signals. This results in a very constant volume, which increases the intelligibility of speech significantly.
If the "ALC" function is active, the microphone gain cannot be adjusted manually any longer. The appropriate menu displays "ALC active!".
The "Noise Canceller" function almost completely eliminated continuously occurring background noise and attenuates punctual background noise. In contrast to the "Noise Gate" function, the "Noise Canceller" is also active when you speak into the microphone.
How to Use the ALC Function
The ALC function provides two options: "Near" for using the microphone close to the mouth "Far" for using the microphone at chest height
You can find both option in the menu at "Audio" > "Input Effects" > "ALC". When using the "Far" setting, the ALC function will activate at a lower speech volume. When using the "Near" setting, you must hold the microphone at a maximum distance of 15 cm to the mouth. Furthermore, the automatic control range of the "Far" setting is higher than of the "Near" setting.

MICROPHONE GAIN AND NOISE SUPPRESSION

132

This means: Due to the higher microphone gain when selecting the "Far" setting, your freedom of movement is bigger compared to the "Near" setting.

"FAR" SETTING
The factory setting "Far" is selected, with which you can optimally use the microphone at a distance of approx. 15 to 25 cm to the mouth (chest height). The advantage of this setting results in an arm-friendly posture and a slightly greater freedom of movement.
Due to the higher gain and the bigger control range, loud background noise can affect the ALC function.

Figure 1-3 How to hold the microphone when using the "Far" setting

MICROPHONE GAIN AND NOISE SUPPRESSION

133

"NEAR" SETTING
The "Near" setting is alternatively available allowing you to use the microphone closer to the mouth (below the chin). In an environment with loud background noise, it is useful to hold the microphone closer to the mouth so that the ALC function can better distinguish between speech signal and background noise.

Figure 1-4 How to hold the microphone when using the "Near" setting
Manual Adjustment of the Microphone Gain Without Using ALC
If you do not want to use the ALC function (e.g. due to extreme background noise in your environment), you can manually reduce the microphone gain for loud speakers and increase the microphone gain for quiet speakers. In both cases use the On/Off and menu button (4) to access the menu at "Audio" > "Volume" > "Internal Mic". If you deactivate the ALC function, please make sure that you keep a constant speaking distance to the mouth to achieve an optimum speech transmission. Avoid holding the microphone closer or further away from your mouth. Also avoid turning your head while speaking.

MICROPHONE GAIN AND NOISE SUPPRESSION

134

Figure 1-5 Optimum speaking distance when the ALC function is deactivated
Compressor and Noise Gate
The ALC and Noise Canceller functions are intelligent DSP algorithms which react to an incoming signal. If very loud and various background noise occurs in your environment, the algorithms can no longer distinguish between microphone signal and noise so that the do not work optimally. This is illustrated by the following example: During a sightseeing tour on the upper floor of an open bus, a strong airflow occurs and enters the microphone capsule. The DSP algorithms ALC and Noise Canceller can not distinguish between airflow and speech signal. For such situations a compressor is available in addition to the automatic control of the microphone gain (ALC). You will find this function in the menu at "Audio" > "Input Effects" > "Compressor". The compressor statically increases the volume of soft speech signals. The following options are available:
"low" = compression 2:1 "high" = compression 4:1 "less pop noise" = relatively high degree of compression to contain explosive sound

MICROPHONE GAIN AND NOISE SUPPRESSION

135

In addition to this, you can use the Noise Gate function instead of the intelligent Noise Canceller. The Noise Gate starts to work at a defined threshold and eliminates background noise during pauses in speech.
You will find this function in the menu at "Audio" > "Input Effects" > "Noise Gate".

INSTALLATION
In order to ensure that the Unite receivers receive radio signals as good as possible, make sure that the front of the Unite AP4 unit points to the area where the Unite receivers will be operating. If reception problems occur, change the mounting position of the Unite AP4 in the room. Make sure that there is a line of sight between the Unite AP4 and the receivers. This can improve reception. In order to install the Unite AP4 and to connect the cable, you must remove the mounting plate from the housing first. Please proceed as follows:
Press the latches on the right and left hand side inwards.
Remove the mounting panel downwards, refer also to the arrow in the drawing.

Mounting to a Wall / Ceiling
Before mounting the Unite AP4 to the wall/ceiling, make sure that there are no electrical, or gas lines or water pipes behind the planned drilling locations. If necessary, check this with a line detector or ask an expert.
It is a significant hazard when electrical or gas lines or water pipes are damaged during drilling.

INSTALLATION

Using a Secondary Safety Rope
The Unite AP4 has two openings through which you can route a secondary safety rope to secure the Unite AP4 additionally against falling down.
In practice, it is the quality of the way in which the equipment is installed that influences the safety of suspension systems for lighting, PAs, monitors, decorations and other objects in the production and event business which are installed using fixing devices intended to allow the equipment to be used in different places (e.g. spigots and sleeves or C hooks). Such applications thus require a secondary safety component. (Source: DGUV Safety for Events and Productions Version 3.2/2015-10) For the preferred direction of threading, refer to the arrow in the drawing.

INSTALLATION

177

USING MULTIPLE UNITE AP4
A maximum of 8 Unite AP4 can be connected with each other so that 32 channels can be sent, received or sent and received depending on the configuration.

To know which version of the Unite AP4 is compatible with your region, contact Televic Conference.

To synchronize the devices, connect the sync signal output of the first Unite AP4 to the sync signal input of the second Unite AP4. Use Cat 5e AWG 24/1 F/UTP cables or better. The assignment must be 1:1.
Connect the Sync signal output of the second Unite AP4 to the Sync signal input of the third Unite AP4, etc.
The first device acts as Sync Master so that each subsequent device receives a clock signal from the Sync Master. In this way the individual DECT channels of the devices are clocked. When using more than one Unite AP4 the synchronisation is absolutely necessary to ensure the operation.

Both, transmitter and receiver, must have the same ID and encryption key. See the "Pairing" section of the Unite TP, or the "Pairing" section of the Unite TH transmitter to establish a connection between them.

By default, the transmitters and receivers are supplied with the group ID 256. A common factory-set audio encryption key, which cannot be changed, is used for the group ID range of 150 to 256. If several receivers are to be divided into different groups with an individual encryption, for each group an individual group ID between 1 and 149 can be assigned.
The scanning procedure is also a dynamic process as the automatic frequency management. This means that the devices scan continuously and do not stop this process independently.

EXTERNAL INTERFACES
The transmitters Unite TP and Unite TH also offer interfaces with which audio signals can be received and/or played: analogue line-in, USB interface and Bluetooth®)
The analogue line-in (Unite TP only) is a 3.5mm 3-pole mini jack connector. Please note that a stereo signal in Unite is converted to a mono signal.
The USB interface (USB 2.0) with a type C connection port can play audio in and out simultaneously. It can also be used as a soundcard when combined with video conference or recording software and as an external soundcard when connected to a PC or Mac computer. Moreover, the device can be supplied with power and recharged via the USB port.
The Bluetooth® interface can also be used both for playing in external audio material and playing back audio signals. This depends upon configuration within the Bluetooth® menu (phone/PC; headset). You can also use a Bluetooth® headset. Please be aware that use of Bluetooth® in general will result in additional latency.
For more information about the connections, please refer to the datasheet of your device avaible on the Televic Conference Knownledge Bas.

EXTERNAL INTERFACES

DEVICE MODE / SUB-MASTER CONFIGURATION
With Unite, the devices are basically divided into the categories "Master" (transmitter) and "Sub-Master" (receiver).
The receivers Unite RP and RP-T are automatically configured as Sub-Master.
The transmitters Unite TP and TH have the factory preset "Master" but can be configured as Sub-Masters to a virtual device mode (Menu: System/Device Mode). In this mode, a channel search must be carried out in order to connect the Sub-Master to a Master and the basic conditions for establishing a connection must be met (see the "Pairing" section of the Unite TP, or the "Pairing" section of the Unite TH for more information) .
Up to three people can communicate with each other. The Unite RP-T receivers have a temporary Talkback channnel, and the Unite transmitters have a permanent one. It means that if two Unite transmitters are configured as Sub-Masters, it won't be possible to use a Unite R-PT as a Sub-Master as the two channels will be permanently used. However, if only one transmitter is configured as a SubMaster, or no transmitter is used at all, it will be possible to use an unlimited number of Unite RP-T devices.
Changing configuration between "Master" and "Sub-Master" takes a few minutes. This involves restarting the device.
In order to make use of this function, all Sub-Master devices must be within range of the Master.

DEVICE MODE / SUB-MASTER CONFIGURATION

TALKBACK FUNCTION (RP-T ONLY)
The green Talkback button on the RP-T is used to activate the internal or externally connected microphone on the RP-T device.
With the Master device, you can define which device can receive the Talkback from the Unite RP-Ts in the groupe. To activate the Talkback option, go to Menu: Talkback > Audio Routing* > RP Talkback.
Transmission of all audio signals within a group is always via the group's central Master (TP) (Broadcast; see fig.: Guided tours with talkback).
A talkback signal from an RP-T device is first sent to the Master (TP) device for transmission to the group. This principle is valid for all signals within a group, including all external signals (fig.: Sound transmission).

NUMBER OF OPEN MICROPHONES
Unite can route a maximum of three simultaneously activated audio signals within a group (NOM=3). This means that, in addition to a group's Master device, two talkback channels can be activated simultaneously.
Unite offers the option to set up whether there should be one or two talkback channels (Menu: Talkback / NOM Talkback*).
When a Sub-Master is active in the group, the number of additional talkback channels that can be activated is reduced to one (fig.: Guided tours with two guides).

Please be aware that the Dante® IP address cannot be viewed or changed via Unite Manager, it must be changed in the Dante® Controller software. Once configured as static IP address, it cannot be changed back to DHCP with the reset button on the back of the device.
The GrandMaster is changing between different devices.
Please make sure that there is only a single DHCP server active in the network. If no preferred Master is set, define the AP4 as GrandMaster that is also the Sync Master in Unite Manager.
There is a connection, but the audio signal is very low or not there at all.
Please check in Unite Manager, if the Input and output levels are set correctly and mute is disabled for each channel.
The Dante® connection causes audio problems that are not reproducible with analogue Inor Outputs.
Please make sure that there is only a single DHCP server active in the network. If a managed switch is used, it can be nececcary to configure it for forwarding of multicast traffic. If necessary, IGMP snooping has to be disabled or an IP address has to be configured as IGMP querier in order to forward multicast traffic.
No further target devices can be connected to a single AP4.

There can be only up to two audio data streams per AP4. For more routing options all channels have to be relayed to a Dante®-enabled mixer first.
The status LED of the Unite AP4 will illuminate green before the device is fully operational. After a reboot it is possible that the device data is not yet completed when the device is read too quickly by the Unite Manager PC software.
When the green status LED of the Unite AP4 shows the ready-tooperation status after a restart, please wait approx. 15 seconds, before you read the device again via the Unite Manager PC software (Discover Devices / Refresh data).
The DHCP IP address of a charger or Unite AP4 is not automatically changed, when the router or subnet is replaced.
Reboot the charger or Unite AP4 when changing the router and/or the subnet to receive a new DHCP IP address on the new network.
In rare cases it is possible that in the Full Duplex HD mode one channel of the used Unite AP4 is displayed as occupied, although this is not the case.
Either restart the Unite AP4 via the Unite Manager PC software or turn the Unite AP4 manually off and on again. Please note that when the Unite AP4 is restarted, all other connected mobile devices must reconnect in the "AP4 Mic (SubM)" mode. In rare cases the device must be restarted so that it can reconnect.
