General Description:
The PC-12/FL and PC-18/FL are multi-pattern miniature gooseneck podium 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 three directional and one nondirectional 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 on
the external electronics module. 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 PC12/FL and PC-18/FL 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 PC-12/FL and PC-18/FL microphones can be mounted in several different ways. They can be mounted on
any fixture that has a standard 5/8" X 27 microphone thread (such as a microphone stand), or they can be
mounted to any flat surface using the included threaded flange. Additionally, they can be mounted using the
included shock mount and adapter. The cable can be easily changed to exit from either the side, or through the
bottom of the microphone.
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
module 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 electronics module can also be surface mounted using the
included mounting clips. The housing is machined brass for ruggedness and superior EMI/RFI attenuation. The
PC-12/FL and PC-18/FL are designed to be phantom-powered with a wide voltage range of 12-52V dc (DIN
Standard 45 596).
PolarChoice Series PC-12/FL and PC-18/FL Microphones
Applications:
The PC-12/FL and PC-18/FL can be used on lecterns, podiums, desk and tabletops, or other applications that require a
threaded or flange mounted 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 gainbefore-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.
