Audio Technica ATW701H UHF Headworn Wireless System

Representing the latest generation of A-T's popular Freeway UHF wireless systems, 700 Series systems provide automatic frequency scanning, which selects an open channel at the touch of a button - an unheard of feature in this price range - for interference-free performance and exceptional audio quality in a diverse range of applications including live performance, houses of worship, public address and aerobic instruction.

Available in handheld, headworn, lavalier, guitar and body-pack configurations, the new 700 Series Freeway systems feature automatic frequency scanning, eight selectable frequency-coordinated UHF channels, diversity operation for interference-resistant reception, and a Tone Lock squelch system that eliminates noise when the transmitter is off. All channels are compatible, so up to eight systems may be used simultaneously. Visual feedback is provided by an LED channel display as well as by antenna and AF Peak indicator lights. Balanced XLR and unbalanced 1/4-inch output connectors allow the 700 Series receiver to interface with the most popular audio inputs.

The 700 Series UniPak transmitter, included with all 700 Series Freeway body-pack systems, features a soft-touch power/mute/off switch, separate instrument/mic trim control, switchable high/low RF power, internal channel selector, multi-color battery/power/mute indicator, professional locking connector and AA battery operation. Four body-pack system configurations are available: the ATW-701 UniPak system (includes receiver and UniPak transmitter only), the ATW-701/G Guitar system, the ATW-701/H Headworn system, and the ATW-701/L Lavalier system. All 700 Series body-pack systems are compatible with the wide selection of Audio-Technica Wireless Essentials microphones and cables.

The ATW-702 Handheld microphone transmitter features a rugged unidirectional dynamic element, and includes a variable microphone trim control, internal channel selector, easily accessible soft-touch power/mute/off switch, multi-color battery/power/mute indicator and AA battery operation.

Both the handheld and body-pack 700 Series Freeway systems provide up to eight hours of continuous use without a battery change. All 700 Series UHF wireless systems offer clear, natural sound quality, and are designed for maximum ease of use.
