The PolarChoice™ PC-12/XLR and PolarChoice™ PC-18/XLR 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 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.

Altering the polar pattern does not change the on-axis sonic character of the microphone; therefore changes in equalizer settings are unnecessary. The PolarChoice™ PC-12/XLR and PolarChoice™ PC-18/XLR 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 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 housing’s 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™ PC-12/XLR and PolarChoice™ PC-18/XLR are designed to be phantom-powered with a wide voltage range of 12-52V dc (DIN Standard 45 596).
