1200 Series

Overview

1200 Series

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
