SOURCE-POWER SYNCHRONIZATION

CHOOSING A SYNCHRONIZATION METHOD

Once you establish that all sour

ce components in the system have compatible IR commands, the next step is

to choose the appropriate sync method for each component.

There are two ways to detect when a component is ON or OFF: Video or Voltage Sync.

V

ideo Sync

V

ideo Sync is the easiest and most reliable method of synchronization. Most video sources have a video out-

put active only when the device is ON. This type of video output provides an excellent method for component
synchronization. The ZR-8630AV has six composite video inputs that include video sync.

Important Note: Some components have a constantly live video signal at the their video output even when the

source component is turned off. Conversely, some source components do not have a constantly live video signal
at their video output even when they are on. Any source component that has either of these attributes cannot use
video sync reliably. You must use voltage sync (see next section of the this manual) or learn discrete on and off IR
commands to automate the power of such source components.

When using voltage sync with a source component that has a video output as described in the previous paragraph,
you must turn off the video sync. For instructions, see page 62.
