5.17 Configuring the backup amplifier system
Select a backup amplifier scenario that will best suit your application needs.
Backup amplifier system variants, each with 'digital audio
matrix':
● 1x program amplifier, 1x backup amplifier, single-channel local backup:
– Variant 1 [➙ 78]
● 3x program amplifiers, 1x backup amplifier, single-channel local backup:
– Variant 2 [➙ 79]
● 7x program amplifiers, 1x backup amplifier, single-channel distributed backup:
– Variant 3 [➙ 80]
● 4x program amplifiers, 1x backup amplifier, single-channel local backup:
– Variant 4 [➙ 81]
● 1x program amplifier, 1x backup amplifier, two-channel local backup:
– Variant 5 [➙ 82]
● 3x program amplifiers, 1x backup amplifier, two-channel distributed backup:
– Variant 6 [➙ 83]
● 1x program amplifier, 1x backup amplifier, four-channel local backup:
– Variant 7 [➙ 84]
● 1x program amplifiers, 1x backup amplifiers, four-channel distributed backup:
– Variant 8 [➙ 85]
● 4x program amplifiers, 4x backup amplifiers, four-channel distributed backup:
– Variant 9 [➙ 86]
● External relay matrix:
– Variant 10 [➙ 87]
Example: Digital audio matrix (4/4/16) with two-channel amplifiers:
Example of a backup amplifier concept [➙ 88]
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 [➙ 133]'.
Backup group composition
● A single backup master with 'Digital audio matrix (4/4/4)', 'Digital audio matrix
(0/4/4)', 'Digital audio matrix (4/4/16)' or Cerberus PACE Compact digital audio
matrix board per group
● Optional: Additional devices known as 'slaves'
● Station ID (SID) range for groups
– The range starts with the backup master and continues all the way through
to the last connected slave in ascending numerical order.
– No gaps are permitted in the station IDs.
Backup master station
● Device to which the backup amplifier is connected
● Has the lowest station ID of the whole backup group
Additional devices
● They are called 'slaves'.
● 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.
