This wireless system comes with the Audio-Technica ATW-R3100 receiver and ATW-T310 UniPak transmitter.

With automatic frequency scanning to find and set the best available channel, 200 selectable UHF channels, true diversity protection from RF hits and dropouts, and soft-touch controls, the 3000 Series wireless delivers truly professional performance.

The versatile UniPak body-pack transmitter features a secure 4-pin locking connector compatible with a wide range of microphones, as well as guitar cables. A 3-position sliding cover on the transmitter's control panel prevents accidental shutoff or channel-switching.

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:
