CAD Audio 2220VP-DSP Variable Polar Pattern Installation Boundary Button Microphone, DSP Controlled - Black

The 2220VP is a continuously variable pattern condenser microphone system with remote polar control through a Digital Signal Processor. The variable polar pattern with remote control allows the user to precisely adjust the shape of the pick-up pattern for best performance from within a DSP. Utilizing a two-conductor shielded cable (max length 2,000 feet) between the microphone head and the DSP unit, the polar pattern of the microphone can be adjusted in real time without changing capsules, microphone positions, or inducing noise in the audio chain. Refer to the specific DSP instructions provided by CAD Audio for the units being used. Special attention has been given to the frequency response and sensitivity of the microphone system while utilizing the variable pattern control to precisely alter the shape of the pick-up pattern. The VP systems are designed to resist interference from devices such as cell phones, two-way communication devices and lighting apparatus.
