The Audio Technica ATW-701 UHF Headworn Wireless System includes the ATW-R700 receiver and the ATW-T701 UniPak transmitter with the PRO 8HEcW hands-free microphone. The ATW-701 UHF headworn system delivers professional features and sound quality unheard of in its class. This easy-to-use wireless microphone system feature eight selectable frequency-coordinated channels, diversity operation for increased range/reliability, manual and automatic frequency scanning, Tone Lock squelch and more.

The ATW-701 system provides a choice of eight PLL synthesized UHF frequencies in the 542-561 MHz band (TV channels 26-29). For multiple-mic applications as many as eight systems may be used together.

ATW-R700 Receiver

The ATW-R700 receiver features diversity reception. Logic circuitry monitors reception, selecting the superior signal from two antennas, providing better sound quality and reducing the possibility of interference and dropouts. Soft-touch controls provide convenient access to selection of operating frequency and automatic scanning, while an LED display indicates selected channel and scanning operation. The ATW-R700 receiver also features a sophisticated Tone Lock tone squelch system that opens the receiver's audio output only when a 700 Series transmitter is detected, reducing the possibility of interference.

ATW-T701 Body-Pack Transmitter

The versatile ATW-T701 UniPak body-pack transmitter has both low- and high-impedance inputs plus a bias connection, for use with dynamic and electret condenser microphones, as well as Hi-Z instrument pickups. The UniPak transmitter also offers separate trim controls for guitar and microphone, plus switchable high/low RF power. The ATW-T701 uses two 1.5V AA batteries for economical operation and wide availability and also features a multicolor Power/Mute/Battery indicator.

PRO 8HEcW Headworn Microphone

Offering highly intelligible individual voice reproduction, the comfortable, lightweight PRO 8HEcW Headworn Microphone is ideal for guitarists, keyboard players, drummers and others who need the use of their hands during performance. Its low-visibility headband and cushioned support pads provide a stable, comfortable fit. Designed for professional quality vocal pickup with hands free operation, the PRO 8HEcW features a pivot-mounted flexible mic boom that descends from either the left or right side.

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:
