Cardioid Condenser Adapter-mount Gooseneck Microphone ยี่ห้อ Audio-Technica รุ่น U857RL
The 16.58″ version of Audio-Technica U857R, the U857RL condenser gooseneck microphone 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 gooseneck microphone direct mounts to any 5/8″-27 stand. Equipped with UniGuard innovations that offer unsurpassed immunity from radio frequency interference. The phantom-powered microphone also offers an 80 Hz low-cut UniSteep filter that reduces pickup of low-frequency ambient noise.
