Audio-Technica’s System is four-channel frequency-agile wireless system designed to provide rock-solid performance along with easy setup and clear, natural sound quality. Featuring sleek, stackable, contemporary styling, System is available in handheld, headworn, guitar, lavalier and body-pack configurations. The system offers four compatible user-switchable VHF channels (169.505, 170.245, 171.045, and 171.905 MHz).
Each System configuration includes the ATW-R900 receiver and either body-pack transmitter or handheld microphone/transmitter. The ATW-R900 is non-diversity, single-channel receiver with advanced dipole antenna design for extended operating range, which improves operation by providing ground element in addition to the usual signal element. The ATW-R900 also offers volume control along with AF Peak, RF and Power indicator lights.

CONSUMER ALERT
Most users do not need license to operate this wireless microphone system. Nevertheless, operating this microphone system without license is subject to certain restrictions: the system may not cause harmful interference; it must operate at 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 FCC’s wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones.
