Backup Amplifier Wiring

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 inputs on all amplifiers being backed up (bus wiring).
