The RB-FS82 audio failover switcher is an important tool in many critical areas in telecommunications and broadcast chains. The device has 8 main + 2 standby, stereo analogue audio, AES/EBU digital audio and RS232 connections (both inputs and outputs) and is used for switching of program sources to a standby destination in the event of a destination failure, or for switching of program sources, including standby sources, to destinations in he event of source failure which would typically be audio decoders at a transmission site.
