The RB-FS82D 8 + 2 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 can be configured via Ethernet for two main operational applications:
Product Features
Relay based switching.
Encoder site (Set via IP): 8 stereo program inputs, 8 + 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): 8 + 2 stereo program inputs, 8 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.
8 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-FS82 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 redundant DC 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.
