Electro-Voice PC18/FL

The PC-18/FL is a multi-pattern miniature gooseneck podium microphone 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 a true "problem solver".  With three directional (Cardioid, Supercardioid and Hypercardioid) and one non-directional (Omnidirectional) 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.  Altering the polar pattern does not change the on-axis sonic character of the microphone; therefore changes in equalizer settings are unnecessary.  The PC-18/FL is 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-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-18/FL is designed to be phantom-powered with a wide voltage range of 12-52V dc (DIN Standard 45 596).
