UniLine® Condenser Quick-Mount Gooseneck Microphone ยี่ห้อ Audio-Technica รุ่น U857QU
Featuring Audio-Technica’s UniLine line-cardioid element with a tightly focused 90º acceptance angle, 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. Featuring 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.
