Offering the realism of a live sound field, the AT4050ST is a side-address condenser with cardioid and figure eight elements, configured in a Mid-Side arrangement. 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.


Innovative, side-address, Mid-Side stereo microphone engineered for professional recording, broadcast and sound reinforcement.

Independent cardioid and figure 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.

Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections.

Integral, 80 Hz high-pass filter switch and 10 dB pad switch.

State-of-the-art design and manufacturing techniques ensure compliance with A-T's stringent consistency and reliability standards.

Custom shock mount provides superior isolation.
