The Audio Technica AT4050ST Stereo Microphone is a stereo side-address condenser microphone with independent cardioid and figure-of-eight elements configured in a Mid-Side arrangement with switch-selectable internal matrixing. It is perfect for professional recording, broadcast and sound reinforcement.
The Audio Technica AT4050ST Stereo Microphone offers the realism of a live sound field. This innovative stereo condenser allows sound recordists the choice of selecting a left-right stereo output or choosing discrete Mid-Side signals for later manipulation, a remarkable flexibility. The microphone’s dual-diaphragm capsules maintain precise polar pattern definition across the full frequency range. Its transformerless circuitry virtually eliminates low-frequency distortion.
Audio Technica AT4050ST Stereo Microphone Features
- Innovative side-address Mid-Side stereo microphone engineered for professional recording, broadcast and sound reinforcement
- Independent cardioid and figure-of-eight condenser elements
- Switch selection of Mid-Side mode and two internally matrixed stereo modes
- Dual-diaphragm capsules maintain precise polar pattern definition across the full frequency range of the microphone
- 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 remain constant over years of use
