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

Microphone Conditions (Additional comments)
Open Circuit Sensitivity At 1 kHz, with 1 Pa (Pascal) = 94dB sound pressure level (SPL), measured at diaphragm. Stated in dB re 1 volt, and in millivolts.
Noise, typical A-weighted, using Audio Precision System One measurement system.
Weight Stated for the microphone only, without accessories, and without attached cable/power module, if applicable.
Frequency Response (Graph) Shows mic output versus frequency with a constant sound input level from a source 0.5 meters from the diaphragm. Each vertical division in the graph is 10dB. A dashed line, if present, shows the effect of a low-roll-off (hi-pass) function.
Polar Pattern (Graph) Shows mic output versus angular direction of the sound source, with a constant sound input level at 1 kHz, at a constant distance from the diaphragm. Zero degrees (0°) is the "front" of the mic. Each circular division in the graph is 5 dB, beginning from the 0° point and counting inward.
