LED Sync Status
Source-power sync ensures that a source component always turns ON when users need it on and that all the
components turn OFF when users turn the system off.
Source Components that Require Power Synchronization
Source components that use the same IR command for ON and OFF need to be synchronized. The power but-
ton for these source components sends the same IR command to turn the source components ON if they are
OFF, and to turn them OFF if they are ON. Synchronizing these source components with the ZR-8630AV is nec-
essary so it knows not to send an ON command if the source components already are ON. (If it did, the source
components would turn OFF, which is not the desired result.) Conversely, synchronization keeps the ZR-8630AV
from issuing a “power” command when the OFF Key is pressed, if the source components are already OFF.
The ZR-8630AV has six Sync Inputs—one for each of the source components. It allows synchronization by means of
voltage and video signals. (See Choosing a Synchronization Method on page 30 for more information on how to syn-
chronize components.)
Source Components that Do Not Require Synchronization
Two types of components do not require synchronization: those with separate ON and OFF IR commands, and
those with “latching power.”
