Audio Technica AT4033A Large Diaphragm Cardioid Polar Condenser Microphone

Audio Technica AT4033A Large Diaphragm Cardioid Polar Condenser Microphone

Ideal for conference centers, boardrooms, courtrooms, houses of worship, and other installed applications, the U857Q is designed to plug directly into a panel- or desk-mounted XLRF-type connector. Offering unsurpassed immunity from radio frequency interference thanks to Audio-Technica’s UniGuard® innovations, this quick-mount microphone features an ultra-flexible, small-diameter gooseneck and accepts interchangeable elements – omnidirectional (360°), cardioid (120°), hypercardioid (100°), and UniLine® (90°) – available separately. Equipped with self-contained electronics, the phantom-powered microphone also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.

Features:

• Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients
• Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity
• The 2-micron-thick, vapor-deposited gold diaphragm undergoes a five-step aging process so that the optimum characteristics achieved remain constant over years of use
• Floating-construction capsule assembly provides isolation from noise and vibration
• Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections
• State-of-the-art surface-mount electronics ensure compliance with A-T's stringent consistency and reliability standards
• Custom shock mount provides superior isolation
