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 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-T702 handheld dynamic microphone/transmitter features a rugged dynamic unidirectional element designed for professional live-sound venues.

Transmitters in the 700 Series use two 1.5V AA batteries for economical operation and wide availability. Both transmitters also feature a multi-color Power/Mute/Battery indicator.

700 Series receivers feature 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. As a result, 700 Series transmitters and receivers must be used together and should not be used with components from other Audio-Technica wireless systems, or with those of other manufacturers.

Please note that in multiple-system applications there must be a transmitter-receiver combination set to a separate channel (frequency) for each input desired (only one transmitter for each receiver).

Because the wireless frequencies are within UHF TV frequency bands, only certain channels (operating frequencies) may be useable in a particular geographic area. The eight channels (operating frequencies) that are used in the 700 Series have been selected for multi-channel compatibility. Subject to frequency availability in a particular geographic area, any of these eight channels may be used together. The operating frequencies that correspond to each of the eight channels are listed on page below.
