Select a backup amplifier scenario that will best suit your application needs.

Backup amplifier system variants, each with 'digital audio matrix':

Example: Digital audio matrix (4/4/16) with two-channel amplifiers:

Example of a backup amplifier concept

In each distributed backup scenario, the group size can be increased by adding additional stations to the backup line. You will find detailed information on the parameters in chapter 'Supervision'.

Backup group composition

  • One single backup master per group
  • Backup master:
    • 'Digital audio matrix (4/4/4)' PC2001
    • 'Digital audio matrix (0/4/4)' PC2002
    • 'Digital audio matrix (4/4/16)' PC2003
    • Cerberus PACE Compact digital audio matrix board PC1001, PC1002
  • Optional: additional digital audio matrices known as 'devices'
  • Station ID (SID) range for groups
    • The range starts with the backup master and continues all the way through to the last connected device in ascending numerical order.
    • No gaps are permitted in the station IDs in the backup group.

Backup master station

  • Digital audio matrix to which the backup amplifier is connected
  • Has the lowest station ID of the whole backup group
  • 1-channel backup, the backup amplifier must be connected to the audio channel 4 of the backup master
  • 2-channel backup, the backup amplifiers must be connected to the audio channels 3 & 4 of the backup master

Additional stations

  • They are called 'devices'.
  • They are connected to the backup amplifier via 'BACKUP-IN'.

Backup group station ID ranges should never interfere with other backup group ranges or station IDs which are not part of the backup group.
