Audio-Technica M3 Wireless In-Ear Monitor System - M Band

M3 - M Band

Audio-Technica's advanced M3 In Ear Monitoring 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 gives allows volume and mix control of two independent signals on stage, via controls on the M3R stereo body-pack receiver.

M3 Components

EP3 Headphones - In-ear dynamic headphones offer high-fidelity sound and excellent isolation

M3T Stereo Transmitter - Wireless UHF transmitter (frequency-agile) offers LCD display and 1321 user-selectable frequencies

M3R Stereo Receiver - Personal Mix Control in a lightweight body-pack with backlit LCD display

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/1/4" 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.

Features:

High-fidelity sound with clean, articulate mix allows performers to hear themselves clearly at lower volume

1321 selectable UHF channels with automatic frequency scanning

Up to 16 simultaneous systems per frequency band

Three receiver modes: Personal Mix, stereo, and mono

Personal Mix Control allows volume and mix control of two independent signals at the receiver

LCD information display offers step-through menus for setting preferences

XLR loop output (true pass-through) connects signal to mixing console, additional IEM system or recording device with no signal degradation

Adjustable squelch eliminates annoying static

Pilot tone protects against RF interference when transmitter is turned off

Multi-level limiter (defeatable) helps protect hearing from sudden peaks

Portable system is quick to load and set up

Reduces on-stage audio clutter for better overall mix & less feedback
