Ideal for conference centers, boardrooms, courtrooms, houses of worship, and other installed applications, the U857Q is designed to plug directly into a panel or desk mounted XLRF type connector. This cardioid condenser quick mount gooseneck microphone offers unsurpassed immunity from radio frequency interference thanks to Audio-Technica’s UniGuard® innovations. The 365mm long microphone 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.
Features:
- 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
