With advanced capsule design coupled with carefully engineered internal electronics, the U857QLU UniLine® condenser delivers clear, consistent sound for a variety of installed applications. The 23.74" version of U857QU, the U857QLU features Audio-Technica’s UniLine® line Cardioid element. The microphone is designed to plug directly into a panel- or desk-mounted XLRF-type connector. 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 U857QLU accepts new 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 gooseneck with 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
Self contained electronics eliminate need for external power module
Accepts interchangeable elements to permit angle of acceptance from 90° to 360°
Accepts UEH(HYPERCARDIOID) UEO(OMNI) UEUL(SHOTGUN) Capsules
Two stage foam windscreen yields dramatically improved resistance to P-pops and other breath blast
Quick mount design with 3 pin XLRM type connector insert at base plugs into any standard XLRF type surface or cable connector
