Architect’s and Engineer’s Specifications
The microphone shall be a large-diaphragm side-address externally
polarized (DC bias) condenser with user-switchable omnidirectional,
cardioid, and figure-of-eight polar patterns and a frequency response of
20 Hz to 18,000 Hz. The microphone shall operate from an external 48V
DC phantom power source. It shall be capable of handling sound input
levels up to 149 dB (159 dB with 10 dB pad) with a dynamic range of 132
dB. Nominal open-circuit output voltage shall be 15.8 mV at 1V, 1 Pascal.
Output shall be low impedance balanced (100 ohms).
The output of the microphone shall be a 3-pin XLRM-type connector.
The microphone shall be equipped with a switchable 10 dB pad, a switch
that permits choice of flat response or 80 Hz low-frequency roll-off, and a
polar pattern selection switch.
The microphone shall be 188.0 mm (7.40") long and have a maximum body
diameter of 53.4 mm (2.10"). Weight shall be 510 grams (18.0 oz). The
microphone shall include a shock mount, a dust cover and a wooden case.
The Audio-Technica AT4050/LE is specified.
In the interest of standards development, A.T.U.S. offers full details on its test methods to other industry
professionals on request.

Specifications are subject to change without notice.
Note: Due to limited production of the AT4050/LE, replacement parts are in limited supply. When the stock
of the AT4050/LE parts is depleted, AT4050 parts will be available.
