It is possible to connect up to four program amplifiers by using a 'Backup-MUX'
(PCA2014) add-on card. This card is controlled via two digital outputs and switches
the audio signal to the backup amplifier in case of a fault. This structure only works
'autonomously' and the concept does not allow multiple 'Digital audio matrix
(4/4/16)' to be cascaded.
