Provides crisp, full-sounding voice pickup and it's effective for acoustic guitars and horns too.

The AT831R also excels as an instrument mic, especially for pickup of acoustic guitar with the included AT8444 guitar adapter. The mic is ideal for higher SPL applications, such as pickup for horns with the included AT8418 UniMount microphone instrument mount. Excellent gain before feedback and suppression of background noise. Operates on phantom power only.

Consumer Alert:

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCCs wireless microphone website at: www.fcc.gov/cgb/wirelessmicrophones.
