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:

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.

PC-18/XLR can be used on lecterns, podiums, desk and table-tops, or

Engineering Data Sheet
EV Multi-Port Windscreen:
All PolarChoice microphones come with the exclusive EV
Multi-Port Windscreen. This unique one-piece ported design
offers greatly improved resistance to P-popping noise by
creating a two-stage filter that has an air space between the
stages. This makes the multi-port windscreen as effective as
much larger traditional designs.
Shock Mount Installation:
Drill a 1-3/8 inch hole to mount the hard plastic flange
into the desk, table, or lectern top. Drill three holes to
secure the flange. The type of screws used to fasten
the flange will depend on the desktop material. To
insert the flexible shock mount:
1. Gently push the flexible shock mount onto the
electronics housing. Position the flexible shock mount
to cover the polar selection switch.
2. Insert the microphone and shock mount into the hard
plastic flange using a twisting action to seat the shock
mount.
