The PolarChoice Desktop is a high quality tabletop microphone
that can be used with both standard and automatic mixers, and is
highly-shielded from RFI/GSM thanks to EV’s exclusive RF Shield
technology.
The PC Desktop features the exclusive EV PolarChoice miniature
multi-pattern gooseneck microphone. The multi-pattern versatility
of the PolarChoice microphone makes it a true “problem solver”.
With one non-directional and 3 directional polar patterns available,
the PolarChoice microphone is ideal for virtually any installation. The
PC Desktop also includes a switchable high pass filter that helps
reduce any vibration induced noise pickup.
The PC Desktop features a large push button mute switch that has
a much better “feel” than membrane switches. The mute button can
be configured for push-on/push-off, push-to-talk, or push-to-mute
function. Switch programming is easily accomplished without
disassembling the microphone. A switch on the bottom quickly
converts the PC Desktop to automatic mixer mode. In this mode,
audio is always on.

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 pickup 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.
