UniLine® Condenser Adapter-mount Gooseneck Microphone ยี่ห้อ Audio-Technica รุ่น U857RU

Featuring Audio–Technica‘s UniLine line-cardioid element, the U857RU adapter-mount gooseneck condenser microphone has a small-diameter gooseneck with virtually no ‘memory’. Its ultra-flexible, robust design permits easy adjustment into desired shape while resisting inadvertent repositioning. The microphone direct mounts to any 5/8″-27 stand; it is 16.81″ long. Equipped with UniGuard® innovations that offer unsurpassed immunity from radio frequency interference, the U857RU 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.

• Designed for high-quality sound reinforcement, professional recording and broadcasting
• UniLine® polar pattern provides narrow 90° acceptance angle
• Superior off-axis rejection for maximum gain before feedback
• UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
• Easy-to-adjust, rugged, small-diameter, alternating gooseneckwith virtually no ‘memory’ permits quick positioning into desired shape
• UniSteep® filter provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality
• Accepts interchangeable elements to permit angle of acceptance from 90° to 360°
• Two-stage foam windscreen yields dramatically improved resistance to P-pops and other breath blasts
• Direct mounts to any 5/8″-27 stand, or to included threaded mounting flange
