INSTALLING MULTIPLE PR-4Zi CONTROLLERS
As many as four PR-4Zis can be cascaded via
DB-25 connectors. Cascading links multizone
functions such as SYSTEM ON, SYSTEM OFF,
PAGING, and PARTY mode so that these func-
tions can be used system-wide. (In order to
share sour
ces among linked PR-4Zis you must
connect the Source Loop outputs of the parent
controller to the A/V inputs of controller #2, and
so on.)
The DB-25 cable needs to be a straight pass-
through or RS232C rated with a male connector
at both ends.
