  • Overview

    Known for outstanding audio quality and reliable performance, this full-rack 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. The receiver is designed to be mounted in a standard 19" rack (1U).
  • Features

    • True diversity reception and full FM deviation

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

    • Choice of 20 VHF frequencies

    • InvisibleLink® circuitry delivers optimum sound quality

    • Ground-lift switch and adjustable squelch control

    • Balanced and unbalanced audio output jacks

    • Receiver mounts in a single 19" rack space

    • Dual-power battery-save switches on transmitters

    • ATW-T27 UniPak® transmitter includes Super Hi-Z input that provides optimum load for guitar pickups

    • ATW-T28 handheld microphone/transmitter features a Hi-ENERGY® dynamic element with superior internal shock mounting

  • Configurations
