The SR 400 diversity receiver is your best choice for cost-efficient,
high-performance multichannel systems. Up to 12 channels* can be
used simultaneously within the same subband and even large systems
will work smoothly in environments hostile to RF transmission.

Being compatible with professional WMS 4000 antenna splitters,
power supplies, and high quality antennas, the WMS 400 enables
you to set up highly complex wireless systems. In Auto Setup mode,
the receiver will scan the available bands, find an interference-free channel,
and transmit the related frequency data to the assigned transmitter via infrared.
This technique significantly reduces the time it takes to set up a multichannel
system. A Rehearsal function identifying dead spots, a programmable display
clearly indicating all important system parameters, twocolor display backlighting
warning the user of critical conditions from a distance, and a transmitter battery
status display on the receiver enhance reliability and add to ease of use.

Features:

    * Integrated frequency scanner with frequency management database
    * Up to 12 channels can be used simultaneously in each subband
    * Infrared data transmission link
    * Rehearsal function for finding dead spots
    * Programmable warning functions using two-color display backlighting

Specifications:

    * Carrier frequency range: 650 to 680, 680 to 710, 720 to 750,
                                          760 to 790, 790 to 820, 835 to 862 MHz

The M3R belt pack receiver is part of the M3 system. Rugged, ergonomic compensate housing includes a field-replaceable flexible-whip antennas. Digital LCD display with soft touch controls. The stereo monitor system offers Personal Mix Control, which gives each musician volume and mix control of two independent signals on stage, via easy-to-use controls on the M2R stereo body-pack receiver. Any number of M2R stereo receivers may be used on the same frequency with a single M2T stereo transmitter. On board 3 level limiter (defeatable) helps protect your hearing from sudden peaks. Includes Audio-Technica earphones with proprietary dynamic drivers offer full frequency response and outstanding isolation with 3 sizes of rubber eartips plus an ear-conforming foam tip. Also, an auxiliary input offers a connection point for an ambient microphone, click track, or other mic- or line-level input.

These rugged systems are built to stand up to the inevitable bumps of life on the road, delivering clear, natural sound for touring and installed-sound uses.

The ATW-T310b wireless UniPak® body-pack transmitter has both low and high impedance inputs plus a 5V DC bian connection allowing it to be used with condenser and dynamic microphones, as well as Hi-Z instrument pickups. The locking 4-pin HRS-type audio input connector is recessed to protect the connection from damage. Operating on two standard AA batteries, the transmitter features high and low-level RF output settings. The low-level setting allows two additional hours of bttery life while retaining a strong RF signal link. Soft-touch controls provide convenient access to a variety of functions including: RF power, audio input level, power/mute locks and frequency selection. Each transmitterʼs backlit LCD display presents a great deal of setup and operating information clearly and conveniently including battery fuel remaining, mute, and operating frequency. A flashing "Lo-Batt” alert visually signals the battery life is almost depleted. A dual-colour status LED illuminates green when power is on, and red when the transmitter is muted. Programmable power/mute locks limit the functioning of the transmitterʼs power/mute button as desired for particular users and applications. To match the audio input level to the transmitter, a four-position audio input gain setting selected through the function menu is provided.

The body-pack transmitter features a safety cover to protect the soft-touch controls from being accidentally activated and a recessed input connector to increase the life of the microphone cable. Constructed of high impact materials, the body-pack transmitter features a field replaceable whip antenna and captive locking battery cover door.
