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
* Modulation: FM

Compatible with the Wireless Essentials® range. Rugged, ergonomic metal housing. Includes field-replaceable helical and flexible-whip antennas. Three-position sliding cover limits access to controls as desired: full access, Power/Mute button only, or no access. Two position mounting clip. For use with AEW-T1000a and all Audio-Technica UniPak™ Wireless Transmitters.
The AEW-T1000a wireless UniPak® body-pack transmitter has both low and high impedance inputs plus a DC bias connection allowing it to be used with both condenser and dynamic microphones. The locking 4-pin HRS-type audio input connector is recessed to protect the connection from damage. A dual-colour power/mute indicator LED provides visual indication of transmitter status. The transmitter operates using two standard AA batteries and features high- and low-level RF output settings. The low-level setting allows two additional hours of battery 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 level remaining, mute, and operating frequency. A flashing "Lo-Batt” alert visually signals the battery life is almost depleted. Programmable power/mute locks limit the functioning of transmitterʼs power/mute button as desired for particular users and applications. Four nameable user presets allow for storage and recall of commonly used settings. To match the audio input level to the transmitter, a ten-position audio input gain setting selected through the function menu is provided. The body-pack features a safety cover to protect the soft-touch controls from being accidently activated and a recessed input connector to increase the life of the microphone cable. Inputs are available on the UniPak® for low impedance microphone and high impedance musical instrument or line input. Constructed of metal, the body-pack transmitter features a field replaceable antenna, captive locking battery cover door, a short rigid helical antenna and a flexible wire antenna.
