SOURCE POWER SYNCHRONIZATION
WHAT IS SOURCE-POWER SYNCHRONIZATION?
The ZR-8630AV has been designed to keep track of the ON/OFF condition of the six source components connect-
ed to the system. This allows automation of source components that use the same IR command for ON and OFF.
For this feature to function as designed, you need synchronization (sync) between the ZR-8630AV and source
components that use the same IR command for ON and OFF. This assures the users of the system that the ZR-
8630AV will always issue power commands correctly when they press a Master Key or the Off Key.
Source Components with Separate ON/OFF IR Commands
Synchronization is not required for source components that respond to separate ON and OFF IR commands.
When power commands are programmed as separate ON and OFF, the ZR-8630AV will issue ON commands
only if sync is not present. Separate OFF commands for source components always are issued when the last
zone turns OFF, regardless of sync status.
Source Components with “Latching Power”
Some source components, such as CD players and tape decks, usually plug into the switched AC outlet of the
preamplifier/receiver with which they are installed. These components turn ON as soon as they have power
on their AC cord, which occurs when the system’s receiver/preamplifier turns ON. In other words, they “latch”
into an ON or OFF state. Because they don’t need an IR command to turn ON or OFF, they don’t need indi-
vidual synchronization.
Since the ZR-8630AV does not provide a switched AC outlet, the 12V Control Output connected to a voltage-
triggered AC power strip (i.e., Niles AC-3) provides perfect control of latching source components. (See
Configuration 1 in the Systems Configurations section of this manual for more information.)
