Overview
Stereo transmitter for use with Audio-Technica M3L and M3M Wireless In-ear Monitor Systems. Equipped with two XLR/¼" combo input connectors and headphone output. Includes AC adapter (country dependent), rack mount adapters, and flexible antenna.
Audio-Technica’s advanced M3 IEM system offers a full range of professional in-ear monitoring features, with a choice of 1321 UHF channels and easy-to-read LCD information displays on both transmitter and receiver for setting preferences. The stereo monitor system is equipped with Audio-Technica’s versatile Personal Mix Control, which allows volume and mix control of two independent signals on stage, via controls on the M3R stereo body-pack receiver. While up to 16 complete M3 systems may be used simultaneously, any number of M3R stereo receivers can operate on the same frequency with a single M3T stereo transmitter. The M3T Stereo Transmitter is equipped with two XLR/¼” combo input connectors into which users can connect line-level inputs (from a mixing console, for example). The M3T also offers a headphone output that allows you to monitor transmitter input signals directly.
