The 18.94" version of the U857Q, the U857QL cardioid condenser quick-mount gooseneck microphone is designed to plug directly into a panel- or desk-mounted XLRF-type connector. The microphone offers unsurpassed immunity from radio frequency interference thanks to UniGuard� innovations. It features an ultra-flexible small-diameter gooseneck and accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine™ line cardioid polar patterns. Equipped with self-contained electronics, 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


• 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�


• 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


• Included shock mount attenuates noise, shock and vibration transmitted through the mounting surface
