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 pictures below we have a backup amplifier that is hot standby for two amplifiers.

Control output/input wiring:

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.

Speaker output/input wiring:'

The orange and green wire is the 100V speaker lines:

  • Channel 1 output on the backup amplifier is wired to channel 1 backup input (labeled BACK-UP 1) on Amplifier 1 and Amplifier 2.
  • Channel 2 output on the backup amplifier is wired to Channel 2 backup input (labeled BACK-UP 2) on Amplifier 1 and Amplifier 2.
