Applications:
PolarChoice Series PC-12/FL and PC-18/FL Microphones
Technical Specifications:
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 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.
