Audio Failover Switcher, 8 Main I/O, 2 Standby I/O
5IF3#'4TVQQPSUTBOZDPOGJHVSBUJPO
of up to 8 main program signal paths (N ≤
8) and there are 2 standby program signal
paths, in either modes of operation. Each
program path simultaneously switches
analogue L/R audio, AES/EBU digital audio
and RS232 data. Each of these signals is
wired on D-type connectors on the rear
panel.
essential for applications such as installation
at transmitter sites, where a power failure
to the unit will not prevent the audio input
signal from being output to each of the
supported 8 transmitters.
All signal paths are passive and therefore
completely transparent utilising relay based
switching. This has the benefit of a “straight
wire” topology during normal (alarm free)
operation and also during any power
outage to the device. An additional benefit
of the passive signal path is AES/EBU bit
transparency allowing throughput of AES/
EBU AC3 Dolby E (TM) signals.
A row of LEDs on the front panel confirm the
unit status, with each individual program
path indicated as being in alarm with either
Standby 1 or Standby 2 programs clearly
confirmed as actively over-riding the failed
signal. Alarm LEDs on the front panel are
also indicated for power supply 1 failure and
power supply 2 failure and these are also
mirrored by the device’s own General Purpose
Outputs so facilitating easy interfacing of the
device with the addition of a summary alarm
status GPO. In the event of alarm clearing,
the unit will automatically revert to normal
operation, but a manual reversion mode
is also provided, allowing for engineering
investigation without the unit ‘hunting’
between different signal paths. Two buttons
on the front panel, RESTORE 1 and RESTORE
2, allow manual restoration of the previously
failed signal paths, away from Standby 1
and Standby 2 respectively and these can be
remotely controlled over Ethernet.
To ensure the passive nature of the device,
switching is determined by alarm (General
Purpose) inputs, with this alarm signalling
in turn being normally provided by the
encoder or decoders (or other devices) at
site. Recognising the mission critical nature
of the system, a high grade of relay is used in
UIF3#'4
The passive design ensures continuity of
audio in the event of any power outage.

supply fails, the other is ready to take over.
In the extremely unlikely event that both
fail, the unit’s passive signal path ensures a
straight wire connection for all 8 program
feeds (analogue, AES/EBU & RS232). This 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:
1. 'PSTXJUDIJOHPGQSPHSBNTPVSDFTUPB
standby destination in the event of a
destination failure (‘Standbys to outputs’).
Typically this would be audio encoders
at a program distribution head end
(for audio over IP, E1 or other bearer
networks), with “N” x programs feeding “N”
x encoders. If an encoder fails the audio
destined for that encoder gets routed
to a standby encoder so ensuring the
continuity of audio to network transport.
2. Switching of program sources, including
standby sources, to destinations in the
event of source failure (‘Standbys to
inputs’). Typically this would be audio
decoders at a transmission site with “N” x
programs and “N” x decoders feeding “N”
x transmitters. If a decoder fails, the audio
from a standby decoder, or other audio
source such as an mp3 player, overrides
the signal path to the transmitter so
ensuring continuity on air.
