Applications:

The PolarChoice™ Desktop is acoustically designed for high-quality sound reinforcement and broadcast applications. The
frequency response is tailored for wide-range sound reproduction with very natural sound pick-up for either distant or close-up
use.  The PC Desktop can be used on lecterns, podiums, desks, table-tops, or other applications. To maximize gain-before-
feedback, the PolarChoice’s™ three directional polar patterns allow the user to pick the directional polar pattern for optimum
effect. For those applications where gain-before-feedback is not a problem, an omnidirectional pattern is included.
Applications requiring speaking close to the microphone at podiums, lecterns, or pulpits normally require a windscreen
(included) to control breath noise and P-popping or, in some cases, wind noise from circulating air.

Compatible Bodypack Models:

Electro-Voice:

REV, RE-1, RE-2

Telex:

FMR-500, FMR-1000, SAFE-1000
(And all future system bodypacks produced after Fall 2006.)
