The phantom-powered U857Q is designed to plug directly into a panel or desk-mounted XLRF-type connector. 14.37" long. It features a small-diameter gooseneck that adjusts easily to any position. It is a cardioid condenser microphone and offers unsurpassed immunity from radio frequency interference thanks to Audio-Technica"s UniGuard technology. Self-contained electronics, phantom-power, plus an 80Hz low-cut UniSteep filter to reduce pickup of low-frequency ambient noise make it easy to use. It also accepts interchangeable elements, available optionally in cardioid, hypercardioid, omni, and UniLine line cardioid polar patterns.
