Audio-Technica AT4050ST manual Specifications

AT4050ST

The output of the microphone shall be a 5-pin XLRM-type connector. A

5.0m (16.5') cable with a 5-pin XLRF-type to two standard 3-pin XLRM- type connectors shall be included.

The microphone shall be equipped with a switchable 10 dB pad and a switch that permits choice of flat response or 80 Hz low-frequency roll-off. It shall also include switch selection of non-matrixed M-S mode and two internally matrixed left-right stereo modes. The M-S mode shall provide independent Mid and Side signals. The two internally matrixed modes shall provide traditional “left-right” stereo with the choice of wide (127°) and narrow (90°) pickup patterns.

The microphone shall be 193.0 mm (7.60") long and have a diameter of

53.4mm (2.10"). Weight shall be 517 g (18.2 oz). The microphone shall include a shock mount, a dust cover, and a protective carrying case.

The Audio-Technica AT4050ST is specified.
