Audio Technica ATW 1453 True Diversity UHF Wireless Systems
-T’s rugged and reliable 1400 Series UHF True Diversity wireless systems include a receiver and either a body-pack or a handheld transmitter on a specific crystal-controlled frequency. The all-metal UHF receiver is equipped with detachable front-mount antennas, balanced and unbalanced outputs, ground lift, adjustable squelch, rackmount capability and True Diversity reception. Two antennas feed two completely independent RF sections on the same frequency; automatic logic circuitry continuously compares and selects the superior received signal, providing better sound quality and reducing the possibility of interference and dropouts.
