The Audio-Technica U857Q Condenser Quick-Mount Gooseneck Microphone provides high-quality sound for professional installations in conference centers, boardrooms, and houses of worship.
The Audio-Technica U857Q Condenser Quick-Mount Gooseneck Microphone is a professional audio solution designed for high-quality sound reinforcement, broadcasting, and recording. This phantom-powered microphone plugs directly into panel- or desk-mounted XLRF-type connectors. It serves installed applications such as boardrooms, courtrooms, and houses of worship with a focus on clear vocal reproduction and reliability.
The U857Q utilizes UniGuard RFI-shielding technology to provide outstanding rejection of radio frequency interference. This protection ensures signal integrity in environments with high electronic activity. The microphone features superior off-axis rejection, which allows for maximum gain before feedback occurs. An integrated 80 Hz UniSteep filter provides steep low-frequency attenuation to reduce the pickup of ambient noise without affecting voice quality.
The microphone features a small-diameter, alternating gooseneck that is both rugged and easy to adjust. This flexible neck has virtually no “memory,” allowing users to position the microphone into the desired shape quickly. The quick-mount design includes a 3-pin XLRM-type connector at the base, which interfaces with any standard XLRF-type surface or cable connector. Self-contained electronics eliminate the need for an external power module, simplifying the installation process.
The Audio-Technica U857Q accepts interchangeable elements to permit different angles of acceptance. Users can modify the pickup pattern from 90° to 360° using elements available separately, including:
A two-stage foam windscreen is included to provide dramatically improved resistance to P-pops and breath blasts. The package also includes a shock mount designed to attenuate noise, shock, and vibration transmitted through the mounting surface. These components ensure the microphone remains stable and clear during professional use.
