UniSteep filter provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality
Accepts interchangeable elements to permit angle of acceptance from 90 degrees to 360 degrees
Low-profile design with low-reflectance finish for minimum visibility
Available in two colors: black (U853A) and white (U853AW)
Operates on battery or phantom power
Audio-Technica U853A Cardioid Condenser Hanging Microphone
Maintaining the Audio-Technica tradition of clear and transparent sound quality, the U853A condenser hanging microphone is ideal for speech, theater, orchestra and vocal choir sound reinforcement and recording. The microphone's fast transient response and low distortion characteristics allow every complex detail to be heard with all its impact—rich, vibrant qualities faithfully reproduced. Equipped with UniGuard innovations that offer unsurpassed immunity from radio frequency interference, the U853A accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine cardioid polar patterns.
