220VP/220VPW
Continuously-variable Pattern Condenser Boundary Microphone
Description
The 220VP/220VPW is an inconspicuous, 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 lter 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, the 220VP will take
advantage of the “boundary effect” signal-to-noise ratio
increase. The 220VP is terminated with a standard 3-pin
XLRM-type connector recessed in the body of the microphone.
The 220VP 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 specied. The installer can precisely tailor the polar pattern
for the best performance depending upon the application
or environment. The 220VP is primarily designed for speech
and vocal pickup in governmental, institutional, religious and
business applications.
