  • Overview


    Known for outstanding audio quality and reliable performance, this professional wireless system includes a True Diversity VHF receiver and either a body-pack or handheld transmitter on a specific crystal-controlled frequency. 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.
  • Features


    • True diversity reception with two independent RF sections for greatest reliability

    • Full FM deviation improves signal/noise ratio for greater headroom and dynamic range

    • Choice of 20 VHF frequencies for minimum interference

    • Ground-lift switch solves hum problems when ground loops are encountered in the field

    • Two receivers can be mounted side-by-side in a single 19" rack space

    • ATW-T35 UniPak® transmitter includes Super Hi-Z input that provides optimum load for guitar pickups

    • ATW-T36HE handheld microphone/transmitter features a Hi-ENERGY® dynamic element and internal pneumatic shock mounting
