The PC-12/FL and PC-18/FL are highly-shielded from
RFI/GSM 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 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 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 PC- 12/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).

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.
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. First route the cable, as desired, either out the side of the mic,
or through the bottom.
2. Screw the included shock mount adaptor into the bottom of the
microphone.
3. Gently push the flexible shock mount onto the adaptor.
4. Insert the microphone and shock mount into the hard plastic
flange using a twisting action to seat the shock mount.

Shock Mount Installation: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 PolarChoice’s 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.
The external electronics module can either be plugged directly into
any standard 3-pin XLR input, or it can be surface mounted in a
location adjacent to the microphone using the provided mounting
clips. If required, the cable between the microphone and the
electronics module can be shortened. Simply cut the cable to the
desired length, and remove sufficient insulation from the wires to
allow the conductors to be inserted into the terminal strip in the
electronics module. Connect the wires to the module as shown
in the wiring guide on this page. For best results, the conductors
should first be tinned with solder.
Mounting the Electronics Module:
1. Disconnect the cable from the electronics module
2. Unscrew the hex retainer from the bottom of the gooseneck.
3. Thread the cable through the knurled ring and hex retainer.
4. Screw the hex retainer back on the bottom of the goose neck
and tighten securely.
5. Reconnect the cable to the electronics module, according to the
wiring diagram.
