Power Syncronization and Component
Compatibility
2A. Power Syncronization
Infrared Turn On/Off Requires “Sync”
Every component which requires an infrared command to turn “On” or “Off” must be
synced to the IntelliControl. Based on the “sync status” of the selected component, the
IntelliControl will know whether or not to issue a “Power” or “On” command when a Master
Key is selected. The same basic procedure applies to turning the system off. The
IntelliControl monitors the on/off status of the components in either of two ways, “12V
Sync” and “Video Sync”.
Components that Don’t Need Sync – Those with Latching Power
Components which “latch” into an “On” state when power is supplied do not need sync.
The term “Latching Power” describes any component which has a Power button which
“latches” into the “On” position and can be turned on automatically when AC power is
supplied. “Single” and “5-disc” CD players, as well as most Tape Decks traditionally plug
into the switched outlet of the preamp/receiver and do not require IR “power” or “On” and
“Off” commands to manage their power. Check the power consumption of each device in
the system and total them. If all of the connected component’s combined power
consumption exceeds the limitations of the preamp’s switched outlet, you must specify a
Niles AC-3 to switch the “On” and “Off”.

a source that utilizes the preamp is selected).
