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.
