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.

Backup Amplifier Wiring


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:
