Engineered for versatile positioning and extremely flexible performance in boardroom, school, government, house-of-worship and other installed applications, the U857ALCW features a small-diameter gooseneck with virtually no "memory." Its ultra-flexible, robust design permits easy adjustment into desired shape while resisting inadvertent repositioning. This cardioid condenser gooseneck microphone direct mounts to any 5/8 in.-27 stand. 29.5 in. (0.75 m) cable terminated with locking 4-pin connector for A-T UniPak body-pack wireless transmitters. Equipped with UniGuard innovations that offer unsurpassed immunity from radio frequency interference, the U857ALCW accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine line cardioid polar patterns. The battery- or phantom-powered microphone also offers an 80 Hz low-cut UniSteep filter that reduces pickup of low-frequency ambient noise.
