The RB-FS42 4 + 2 audio failover switcher is a smaller channel count version of the RB-FS82, offering a lower number of inputs and outputs. It is a more cost effective solution where failover is needed for a smaller number of sources/destinations and supports all of the features of the RB-FS82. The device has 4 main + 2 standby, stereo analogue audio, AES/EBU digital audio and RS232 connections (both inputs and outputs) and can be configured via Ethernet for two main operational applications:
Product Features
Relay based switching.
Encoder site (Set via IP): 4 stereo program inputs, 4 + 2 stereo program outputs where each program input/Output carries: analogue L/R, stereo AES/EBU & RS232.
Encoder site: Each program output has an alarm detect GP input.
Decoder Site (Set via IP): 4 + 2 stereo program inputs, 4 program outputs where each program input carries: analogue L/R, stereo AES/EBU & RS232.
Decoder Site: Each program input has an alarm detect GP input.
4 programme I/O paths, 2 standby output paths.
AES/EBU transparent (for Dolby E transport).
Passive throughput in event of power outage.
GP output for signalling RB-FS42 alarm conditions: PSU 1/2 fail, Standby 1/2 active, Summary Alarm.
Automatic or Manual reversion modes.
LED indicators on front panel.
IP control, including Web GUI and SNMP.
Dual AC power supplies (select when ordering).
Typical Applications
As a failover switcher for multi channel audio transport over E1 or IP, typically as performed by APT Oslo, Prodys Nureus, where a N+1 topology is adopted.
