U857QLU Audio-Technica | Audio-Technica

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, smalldimeter, 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°.

Two-stage foam windscreen yields dramatically improved resistance to P-pops and other breath blasts.

Quick-mount design with 3-pin XLRM-type connector insert at base plugs into any standard XLRF-type surface or cable connector.

Optional shock mount attenuates noise, shock and vibration transmitted through the mounting surface.
