Variable pattern installation boundary "button" microphone RF/VP/REMOTE
220VP
Continuously Variable Pattern
Condenser Boundary Microphone
Miniature installation, continuously variable polar pattern, button-style,
condenser boundary microphone designed for surface installation. Special
attention has been given to design the 220VP to resist interference from cell
phones, two-way communication, and other RF devices. The integral 80Hz,
12dB/octave high-pass filter removes unwanted low-frequency energy to
improve intelligibility. The all metal, threaded body and shock-absorbing
bushings make for easy installation in surfaces up to 3” thick. For remote
polar control add the VPC-1 or a compatible DSP. Available in Black or White
(add “W” to the model number for white).
