— Independent cardioid and figure-of-eight elements, along with the choice of variable stereo output or discrete mid-side signals, offer users different sound capture options —

Stow, OH 09-09-2009 – Audio-Technica, a leading innovator in transducer technology for over 45 years, introduces the AT4050ST Stereo Condenser Microphone, a stereo version of A-T’s award-winning AT4050 and one of the new offerings from A-T’s expanding 40 Series microphones. The AT4050ST, developed in direct response to feedback from end users, is a stereo side-address externally polarized (DC bias) condenser microphone with independent cardioid and figure-of-eight elements, configured in a mid-side arrangement with switch-selectable internal matrixing. The AT4050ST offers sound recordists the choice of selecting a left-right stereo output (wide 127º or narrow 90º) via the microphone’s internal matrixing system or choosing discrete mid-side signals for later manipulation. It is designed to meet the most critical acoustic requirements of professional recording, broadcast and sound reinforcement. It performs particularly well in the following recording applications: overheads, piano, classical/string ensembles, group vocals, acoustic/bluegrass bands and any other situations requiring an elegant, versatile stereo condenser microphone solution.

The AT4050ST’s dual-diaphragm capsule design maintains precise polar pattern definition across the full frequency range of the microphone. Unwanted internal reflections are minimized by the symmetrical housing assembly’s open acoustical environment. Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients. The 2-micron-thick vapor-deposited gold diaphragms undergo a five-step aging process so that the optimum characteristics achieved remain constant over years of use.

The microphone includes a 5.0 m 16.5′ dual-output cable terminating in a 5-pin XLRF-type to two standard 3-pin XLRM-type connectors. The output of the microphone is a 5-pin XLRM-type connector. The microphone requires 48V phantom power for operation. The microphone is equipped with a switchable 10 dB pad and a switchable 80 Hz high-pass filter.

The AT4050ST is enclosed in a rugged housing. The AT4050ST’s state-of-the-art design and manufacturing techniques ensure compliance with A-T’s stringent consistency and reliability standards; the mic is RoHS compliant, meaning it is free from all substances specified in the EU directive on hazardous substances. The included AT8449 shock mount provides superior isolation and permits mounting on any microphone stand with 5/8”-27 threads. A dust cover and a protective carrying case are also included.

The AT4050ST Stereo Condenser Microphone will be available November 2009 with a U.S. MSRP of $1,625.00. For more information, please visit
