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 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:
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).

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 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.

EV Multi-Port Windscreen:
Engineering Data Sheet
Shock Mount Installation:
Changing the Cable from Side Exit to
Bottom Exit:
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.
1) Disconnect the cable from the electronics module
2) Unscrew the hexretainerfromthe bottom of the gooseneck.
3) Thread the cable throughthe knurledring 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
thewiringdiagram.
Mounting the Electronics Module:
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.
