CO1-2 Combiner

2.4 “PORT IN” Connector.
If you use two EXPERT amplifiers from this connector, use a Y-cable to interconnect the
"PORT" connector of each amplifier.
This allows the synchronization of the two amplifiers; if not, an alarm will occur.
The two amplifiers are synchronized when their settings are perfectly identical, therefore
this cable is necessary in order for the Combiner to function properly.
This connector is not used with non-Expert amplifiers.
