The CAD Audio 220VP White is an inconspicuous, continuously-variable polar pattern, button-style, condenser boundary microphone designed for surface installation. Special attention has been given to design 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. When mounted on a hard surface, it will take advantage of the "boundary effect" signal-to-noise ratio increase. It is terminated with a standard 3-pin XLRM-type connector recessed in the body of the microphone.
It features a continuously-variable polar pattern so it can shorten the list of products an audio system designer needs to consider when boundary condenser microphones are specified. The installer can precisely tailor the polar pattern for the best performance depending upon the application or environment.
