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
