Operation
NAD ATO LOGIC
The CI-series amplifier may be turned on in any one of three discrete ways for complete system flexibility:
From the front-panel switch, the 12V-TRIGGER circuit, or by a “SLEEP/WAKE” signal-sensing circuit. The
ON/OFF power control is managed by the Automated Turn-On logic or ATO Logic circuit that requires the
amplifier to be switched back to standby in the same manner by which it was activated. In other words,
if the amplifier is switched on via a 12V-control signal, it cannot be switched to standby via the front-panel
switch, it must wait for removal of the 12V-control signal. In practice, you probably would use only one
of the methods once the NAD CI-series amplifier is installed.
