PDC Audio Output for Record:
The audio output of peripheral plugged on PDC connector.
PDC Connectors:
There are 2 sets of PDC port in RU-Main, each set consist of three connectors, allow system to do one
PDC peripheral redundancy, the "N" is the number of set:
P_PDC N
Connect to one of primary audio processor's PDC connectors.
PDC N
Connect to peripheral which communicates to audio processor using PDC interface, for
example PSS-AS, PPM-AS.
S_PDC N
Connect to one of secondary audio processor's PDC connectors.

There are 8 sets of Zone Amplifier Input in RU-MAIN, each set consist of three connectors, allow
system to do one channel of zone amplifier redundancy, the "N" is the number of set:
P_ZONE N
Connect to Nth channel of primary audio processor's zone amplifier input connector.
ZONE N
Connect to Nth channel of normal amplifier's audio input connector.
S_ZONE N
Connect to Nth channel of secondary audio processor's zone amplifier input connector.
EXP_OUT (Active Control Expansion Output):
This port output logic signal to next RU devices to synchronize redundancy state which tells primary
or secondary is active.
