Audio-Technica U857QL 19" Cardioid Condenser Quick-Mount Gooseneck Microphone

The Audio-Technica U857QL 19" Cardioid Condenser Quick-Mount Gooseneck Microphone is an exceptional choice for high-quality sound reinforcement, professional recording, and broadcasting applications. This microphone features an ultra-flexible small-diameter gooseneck and a cardioid polar pattern, offering superior off-axis rejection for maximum gain before feedback. Notably, it incorporates the unique UniGuard RFI-shielding technology, ensuring outstanding immunity from radio frequency interference. With self-contained electronics powered by phantom power, the U857QL also comes equipped with an 80 Hz low-cut UniSteep filter that reduces the pickup of low-frequency ambient noise, enhancing overall sound pickup without affecting voice quality.

The U857QL’s specialized design allows it to be plugged directly into a panel- or desk-mounted XLRF-type connector. Its quick-mount design and rugged construction make it incredibly easy to adjust and position, catering to various professional environments. This microphone accepts interchangeable elements to accommodate different polar patterns, including cardioid, hypercardioid, omnidirectional, and the UniLine line cardioid. Its two-stage foam windscreen significantly improves resistance to P-pops and other breath blasts, ensuring clear and clean audio capture.
