AUDAT831B - Audio Technica AT831B Miniature Cardioid Condenser Lavalier Mic TA3F or AT8531 Image 2

The AT831b requires 11-52V DC phantom power, or a 1.5V AA battery for operation. A battery need not be in place for phantom power operation.

This clip-on lavalier mic AT831b provides crisp, full-sounding voice pickup and excels as an instrument mic, especially for pickup of acoustic guitar with included AT8444 Instrument Microphone Adapter. It offers excellent gain before feedback and suppression of background noise. An integral 80 Hz high-pass filter provides easy switching from a flat frequency response to a low-end roll-off.

AT831b: 6\' (1.8 m) permanently attached cable terminated with TA3F connector; AT8531 power module (with 80 Hz high-pass filter) for battery or phantom power.
