Description
The PolarChoice are back-electret condenser gooseneck podium microphones designed for sound reinforcement systems where sound clarity and gain-before-feedback are of major importance. The flat-bladed screwdriver activated rotary selector switch has the following settings:
Switch Setting Polar Pattern 0 Omnidirectional 1 Cardioid 2 Supercardioid 3 Hypercardioid
Altering the polar pattern does not change the on-axis sonic character of the micro­phone; therefore changes in equalizer set­tings are unnecessary.
The PolarChoice are 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 small-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 ex-

actly position the microphone. The electron­ics housing’s 3/4-inch diameter base is ter­minated with an XLR-type 3-pin connector which allows the microphone to be plugged directly into an existing panel-mount XLR receptacle. The housing is machined steel for ruggedness and superior EMI/RFI attenuation. The PolarChoice PolarChoice tom-powered with a wide voltage range of 9-52V dc (DIN Standard 45 596).
Applications
The PolarChoice can be used on lecterns, podiums, desk and table-tops, or other applications which re­quire a quick plug-in gooseneck microphone. To maximize gain-before-feedback the PolarChoice directional polar patterns which 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. A small external foam windscreen is included with

Architectural & Engineering Specifications
PolarChoice
The microphone shall be a back-electret con­denser type with a frequency response of 75 Hz to 15 kHz. The microphone shall have a nominal, balanced output impedance of 200 ohms. The microphone shall have four selectable polar patterns: omnidirectional, cardioid, supercardioid, and hypercardioid. The microphone shall have an output power level of -44 dB, where 0 dB = 1 milliwatt per pascal, and outputs shall not be appre­ciably affected by the following temperature and humidity extremes: -29° to 74° C (-20° to 165° F) when the relative humidity is 0-50%; -29° to 57°C (-20° to 135°F) when the relative humidity is 0-95%.
Dimensions shall be 20 mm (0.79 in.) diam­eter and 409.7 mm (16.1 in.) long. The mi­crophone shall include a 298.5 mm (11.8 in.) gooseneck with professional XLR-type 3-pin style terminating connector and an external windscreen. The microphone shall have a nonreflecting black finish. Termination to the electronics module shall be a 3-pin male XLR type connector. The microphone shall
