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

LD Systems MEI1000G2

The LD Systems MEI 1000 G2 is an advanced LICENSE FREE* 96 channel UHF in-ear monitoring system delivering natural sound with extended dynamics and low crosstalk in both the 823 - 832 and 863 - 865 MHz bands.

Switchable mono, stereo and focus modes select the perfect monitoring applications while adjustable EQ and limiter functions have been integrated for consistent sound reproduction from 60Hz - 16 kHz with a high S/N ratio and low THD. The LD MEI 1000 G2 allows the use of up to 5 systems simultaneously.

The earphones have been designed for a high wearing comfort, and a multifunction display provides all the relevant system information. Operation time exceeds 12h with high quality batteries. A 19" rackmount kit and a rugged ABS plastic carrying case complete the MEI 1000 G2 package.
