AT831B
Miniature Cardioid Condenser Microphone (Phantom only)
This clip-on lavalier mic provides crisp, full-sounding voice pickup. It also excels as an instrument mic, especially for pickup of acoustic guitar. The wired configuration (AT831R) includes the AT8444 guitar mount. The mic is ideal for higher SPL applications, and offers excellent gain before feedback and suppression of background noise. Includes windscreen and clothing clip.
Available configurations:
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.
AT831c: 10' (3 m) permanently attached cable (unterminated); no power module.
AT831cH: 55" (1.4 m) permanently attached cable terminated with a screw-down 4-pin connector for use with Audio-Technica cH-style body-pack wireless transmitters; no power module.
AT831cW: 55" (1.4 m) permanently attached cable terminated with cW-style locking 4-pin connector for use with Audio-Technica cW-style body-pack wireless transmitters; no power module.
