Audio Technica ATW-2129 True Diversity UHF Lavalier Wireless System
Serious advances in affordable professional wireless allow for clear sound quality and rock-solid, dependable performance. Automatic frequency scanning finds an open channel at the touch of a button. And all 10 user-switchable channels are compatible for easy use with multiple systems; no confusing frequency groups. The True Diversity operation selects the best signal from the two receiver sections, thus reducing dropouts and the Tone Lock™ tone squelch system fights background interference. Built from rugged metal half-rack receiver with soft-touch controls and LCD display featuring RF and AF metering. Balanced XLR and unbalanced 1/4” output jacks enable use with a wide variety of audio gear. Ground-lift switch helps eliminate audible hum caused by ground loops between the sound system and receiver. Includes rack-mount kit and detachable UHF antennas.
