The small-diameter double gooseneck design permits highly flexible positioning while maintaining a smooth, well-contoured appearance. The U857Q stands 365.0 mm (14.37") from the table or podium; it is also available in a 481.0 mm (18.94") version as U857QL. The two models are identical in all other respects. The microphone requires 11V to 52V phantom power for operation. The microphone is equipped with UniGuard RFI-shielding technology, which offers outstanding rejection of radio frequency interference (RFI). The microphone's cardioid polar pattern provides a 120° angle of acceptance.

Additional interchangeable elements with omnidirectional (360°), hypercardioid (100°) and UniLine (90°) pickup patterns are available. An XLRM-type connector insert at the base allows the microphone to be plugged directly into an XLRF-type panel jack or microphone cable. A recessed switch permits choice of flat response or low-frequency rolloff (via integral 80 Hz high-pass UniSteep filter) to help control undesired ambient noise. The microphone comes equipped with a two-stage foam windscreen and a shock mount designed to attenuate noise, shock and vibration transmitted through the mounting surface. The microphone is enclosed in a rugged housing with a low-reflectance black finish. Installation and Operation The U857Q requires 11V to 52V phantom power for operation. Output is low impedance (Lo-Z) balanced. The signal appears across Pins 2 and 3; Pin 1 is ground (shield). Output phase is Pin 2 hot positive acoustic pressure produces positive voltage at Pin 2.

The microphone can be mounted in a permanent installation (on a lectern, pulpit, conference table or similar surface) with the included AT8662 shock mount. The AT8662 effectively isolates the microphone from noise, shock and vibration transmitted through the mounting surface and eliminates pickup of low-frequency resonances caused by mechanical coupling. The provided two-stage foam windscreen simply slips over the head of the microphone, effectively reducing wind noise or popping. An integral 80 Hz high-pass UniSteep filter provides easy switching from a flat frequency response to a low-end roll-off. The roll-off position reduces the microphone's sensitivity to popping in close vocal use. It also reduces the pickup of low-frequency ambient noise (such as traffic, air-handling systems, etc.), room reverberation and mechanically coupled vibrations. To engage the UniSteep filter, use the end tip of a paperclip or other small pointed instrument to slide the switch toward the bent line. Avoid leaving the microphone in the open sun or in areas where temperatures exceed 110° F (43° C) for extended periods. Extremely high humidity should also be avoided.
