This article describes how to wire the backup amplifier solution. Exigo ENA Amplifiers have inbuilt support for backup amplifier switch-over where one amplifier can be designated as backup for up to six other amplifiers.
Wiring
The backup amplifier needs to be wired to the amplifier(s) it should monitor:
- One control output (24V DC) from the backup amplifier is connected to each of the backed up amplifiers (star wiring).
- The speaker loop outputs from the backup amplifier is connected to the back-up inputs on all amplifiers being backed up (bus wiring).
Example
In the picture below we have a backup amplifier that is hot standby for two amplifiers.
The red and blue wiring is the control outputs from the backup amplifier to the two backed up amplifiers:
- Control output 1 (24V DC) on the backup amplifier is wired to the control in (labeled CTRL IN) on Amplifier 1.
- Control output 2 (24V DC) on the backup amplifier is wired to the control in (labeled CTRL IN) on Amplifier 2.
The orange and green wire is the 100V speaker lines:
