RFI DAB Headend 2 Ensembles

The DAB174230 series can be used to receive DAB or DAB+ Broadcast signals off-air, and re-generate and amplify them to fixed RF output levels. The DAB174230-1 provides the rebroadcast of one DAB or DAB+ ensemble, and the DAB174230-2 provides the rebroadcast of two DAB or DAB+ ensembles. Multiple DAB174230 units can be implemented within a design to rebroadcast more than two ensembles when required. One RF output is provided for rebroadcasting signals into a tunnel bore. Two (or more) units may are required for multi-bore and multizone applications (such as two separate "bores" in a road tunnel). An "audio break-in" feature enables live or pre-recorded messages to interrupt the rebroadcast transmissions on all stations in all ensembles being rebroadcast , allowing for public address or incident management messages to be broadcast. Break-in messages may be stored within the unit, interfaced via analogue audio inputs, or interfaced via (optional) VOIP. A comprehensive integral webserver GUI provides configuration and status display of the unit's comprehensive functionality and performance monitoring.
