Description
The PolarChoice™12 and PolarChoice™18
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 micro-
phone; therefore changes in equalizer set-
tings are unnecessary.
The PolarChoice™12 and PolarChoice™18
are acoustically designed for high-quality
sound reinforcement and broadcast applica-
tions. The frequency response is tailored for
wide-range sound reproduction with very
natural sound pick-up for either distant or
close-upuse. Thesmall-diametergooseneck
has two supple joints and a rigid center tube.
The rigid tube prevents unsightly twisting
of the gooseneck but permits the user to ex-
actlyposition the microphone. The electron-
ics housing’s 3/4-inch diameter base is ter-
minated 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™12 and
PolarChoice™18 are designed to be phan-
tom-powered with a wide voltage range of
9-52V dc (DIN Standard 45 596).
Applications
The PolarChoice™12 and PolarChoice™18
can be used on lecterns, podiums, desk and
table-tops, or other applications which re-
quireaquickplug-ingooseneckmicrophone.
To maximize gain-before-feedback the
PolarChoice™’s multipolar design has three
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 prob-
lem an omnidirectional pattern is included.
Applications requiring speaking close to the
microphone at podiums, lecterns, or pulpits
normally require a windscreen to control
breathnoiseandP-poppingor, in some cases,
wind noise from circulating air. A small
external foam windscreen is included with
the PolarChoice™12 and PolarChoice™18
microphones for those applications.
