PR 20
The PR 20 has been designed for commercial broadcast, recording and live sound reinforcement applications. This is a very rugged microphone, which makes it ideal for professional use.
The PR 20 achieves its exceptional performance by using a special magnet structure and a large aluminum 1 1/8" low mass voice coil assembly. Special attention has been paid to the phasing plug assembly with equally placed ports that sense audio from behind the source entering them out of phase. This produces a very linear cardioid pattern and reduces the proximity effect while achieving a naturally articulate frequency response.
The PR 20 features -30 dB of rear rejection, which blocks unwanted audio from entering the rear of the microphone. This can prevent bleed when used on a live sound stage or in a recording studio.
This microphone was designed for close range uses. We recommend having audio sources approximately 2 inches from the end grill for best results.
