Audio-Technica specifications U859QL Cardioid Condenser QUICK-MOUNT Gooseneck Microphone

U859QL CARDIOID CONDENSER QUICK-MOUNT GOOSENECK MICROPHONE

• Designed for high-quality sound reinforcement, professional recording and broadcasting

• Superior off-axis rejection for maximum gain before feedback

• 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

•Quick-mount design with 3-pin XLRM-type connector insert at base plugs into any standard XLRF-type surface or cable connector

The U859QL requires 11V to 52V phantom power for operation.

Output from the microphone's XLRM-type connector 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.

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.

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.
