General Description:
The PolarChoice
microphones designed for sound reinforcement systems where sound quality and gain-before-feedback is of
major importance. The multi-pattern versatility of the PolarChoice microphone makes it true problem solver.
With 3 directional and one non-directional polar pattern available, the PolarChoice microphone is ideal for
virtually any installation. Polar patterns can be easily changed, using a small flat bladed screwdriver with the
front mounted rotary control. The control switch has the following settings:

Switch Setting Polar Pattern
Altering the polar pattern does not change the on-axis sonic character of the microphone; therefore changes in
equalizer settings are unnecessary. The PolarChoice
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 small, dual diameter gooseneck has two supple joints and a rigid center tube. The rigid tube prevents
unsightly twisting of the gooseneck but permits the user to exactly position the microphone. The electronics
housings 3/4-inch diameter base is terminated with a male XLR-type 3-pin connector that allows the
microphone to be plugged directly into an existing panel-mount XLR receptacle. The housing is machined brass
for ruggedness and superior EMI/RFI attenuation. The PolarChoice
are designed to be phantom-powered with a wide voltage range of 12-52V dc (DIN Standard 45 596).

Applications:
The PolarChoice
other applications which require a quick plug-in gooseneck microphone. To maximize gain-before-feedback the
PolarChoices 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 to control breath
noise and P-popping or, in some cases, wind noise from circulating air.
