A231

LARGE DIAPHRAGM CONDENSER VOCAL MICROPHONE

OVERVIEW

The A231 is a large diaphragm condenser microphone built for the most discerning studio user. With its externally-biased "true condenser" capsule and low-noise circuitry, the A231 is able to capture the nuances of the human voice as well as the rich overtones of acoustic instruments with natural warmth and in stunning detail. An exceptionally consistent cardioid polar pattern focuses on the performance while offering smooth off-axis rejection.

The 33 mm condenser capsule of the A231 features a precision-tensioned diaphragm made from a specially formulated, heat-treated film with gold deposition distributed evenly to the far edges of the diaphragm. The result is a 25% greater effective diaphragm area when compared to the capsule of a typical large diaphragm microphone.

Behind the double-woven steel mesh grille of the A231, acoustic reflections and diffractions are minimized for transparent sound capture. The internal shock mount isolates the capsule from mechanical vibrations, eliminating the need for a bulky external shock mount. Proprietary impedance control between the capsule and circuitry ensures consistent and reliable performance across a wide range of environments.

Designed, machined, assembled, and tested by Audix in Wilsonville, Oregon.

OPERATION AND MAINTENANCE

The A231 is a low impedance microphone and should be plugged into a "mic level" input on your console, mixer, or recording device with 48 V phantom power. Allow a minimum of 20 seconds for the A231 to stabilize after phantom power is supplied.

Avoid plugging or unplugging the microphone from a PA system unless the channel is muted, or phantom power to the A231 channel is turned off. Failure to do so may result in a loud "popping" noise or damage to the PA system or studio monitors.

The A231 is manufactured to exacting specifications. The capsule is highly sensitive and the microphone should be handled with care. Avoid exposing the microphone to extreme temperatures, moisture, and shock. Store your microphone in a protective case when not in use.

USER TIPS

The sound source should face the Audix logo, which indicates the front of the microphone.
