Overview

Choose the 2220VPW when an installed boundary style
microphone is needed. System includes 220VP boundary microphone with
mounting hardware and rubber bushings. The system also includes 24” XLR-F
to Phoenix-type connector. Specify “W” for white unit.

Details

The 2220VPW 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. Utilizing our RF Resistant
Architecture, our VP products meet the stringent RF standards set by the
European Union (see the specification section of each microphone for
more information).
