AKG SR 4000 TRUE DIVERSITY UHF w-SELECTABLE FREQUENCIES RECEIVER

SR 4000 

True diversity receiver with all-metal case
30 MHz wide UHF band with up to 1200 selectable frequencies
Pilot tone data transmission for battery status monitoring and tone code squelch
PC interface for remote control and status monitoring; logic output for controlling
external devices
Backlit, programmable color display and jog wheel for ease of use
Auto Setup, Environment Scan, and Rehearsal functions for easy setup

The new SR 4000 is a state-of-the-art, true diversity receiver that provides maximum ease of use
and the most useful functions in its class. Many features of the SR 4000 were never before available
or limited to extremely expensive systems.
The accurate battery life readout is an invaluable advantage in live sound applications. The transmitter
uses a pilot tone to transmit battery status data to the receiver that displays the remaining battery
capacity in hours.
The pilot tone decoder also detects and displays other important information including the current
position of the MUTE switch on the transmitter.
The integrated software does not only permit automatic setup and frequency scanning but remote
control and monitoring from a PC via a dedicated interface as well. Optional MCS 4000 Mission Control
Software makes setting up and monitoring highly complex systems incredibly easy. A logic output allows
remote control of specific functions on an external device, e.g., an automatic microphone mixer.
Naturally, the SR 4000 operates in an extremely wide UHF band (30 MHz) and each frequency preset
provides up to 24 intermodulation-free subchannels*. The maximum number of selectable frequencies is
1200. The large, backlit color display and a jog wheel make the SR 4000 easy to use and a programmable
warning light indicates selectable critical conditions within the system. Housed in a half-rack, all-metal
case, the SR 4000 is the most compact, reliable, and powerful UHF receiver in its price bracket.

* The number of channels that can be used simultaneously depends on local frequency plans.
