6.3.17 Backup with 'Backup extension PC2003' PCA2014-A1
If all analog audio outputs of PC2003-A1 are used and only one backup amplifier is
required, the 'Backup extension PC2003' PCA2014-A1 can be used.
The 'Backup extension PC2003' PCA2014-A1 is mounted directly on the analog
audio outputs of the PC2003-A1. It provides all 4 analog outputs to connect the
amplifier. The PCA2014-A1 requires 2 logic control outputs to select the required
analog audio signal for the backup amplifier.
