Audio relay with remote channel control
Relay low-power audio signals
Receives audio from compatible low-power transmitters and retransmits it on a separate frequency band to a remote receiver.
Select channels remotely
Store four receive channels and one transmit channel. Use the supplied remote to select channels and switch between clear and coded transmission.
Configure the antenna setup
Built-in antennas and external connections support different setups. External directional antennas can help extend the link, depending on installation and radio conditions.
Full description
A separate relay link for compatible audio transmitters
The ENRRU-010 audio repeater receives compatible analog or digital transmitter signals in the 416–421 MHz band and relays them at 1,010–1,070 MHz. It supports GMSK or WFM modulation and delivers at least 0.5 W into a 50 Ω load.
Output can be clear or delta-modulation coded for reception by matching equipment. Memory holds up to four receive channels and one transmit channel. External directional antennas provide an option for extending the relay link; range depends on the complete radio setup.
Remote operation and protected connections
The included ENDPK-003 controller operates over a 140–150 MHz radio link. It manages operating modes, channel selection, and clear or coded transmission without requiring access to the repeater control panel.
The main components are protected against dust and moisture, with the controls beneath the case lid. Built-in antennas and a power supply are provided, along with sealed connections for external antennas and external power.
An independently powered central monitoring module with recording capability is available on request.

Applications
Extend an audio monitoring link
Relay signals from compatible low-power audio transmitters to a more distant receiving station. Select antennas and receiving equipment for the relay frequency and operating environment.
Manage stored channels remotely
Use ENDPK-003 to select stored channels and transmission modes when the repeater panel is not readily accessible. The dedicated control link keeps these functions available remotely.
Add a recording station
Specify the optional central monitoring module when the system requires recording. Its independent power supply supports a separate monitoring and recording setup.
Technical support
Equipment matching
Review the source transmitter and relay receiver frequencies, modulation, and coding before selecting the configuration.
Configuration and training
Support for channel configuration, remote-control functions, and external antenna options.
After-sales support
