Audio Technica Microphone - Unipoint Gooseneck Microphone - U857QU UniLine™ Condenser Quick-Mount, 3-Pin XLRM Connector, 250 ohms, phantom-power, Designed for high-quality sound reinforcement, Easy-to-adjust, rugged, small-diameter.

The U857QU quick-mount gooseneck condenser microphone is designed to plug directly into a panel- or desk-mounted XLRF-type connector; it is 19.17” long. Its ultra-flexible, robust gooseneck permits easy adjustment into desired shape while resisting inadvertent repositioning. Equipped with UniGuard™ innovations that offer unsurpassed immunity from radio frequency interference, the U857QU accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine™ line cardioid polar patterns. The phantom-powered microphone also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.
