Rotel amplifiers that do not include signal sense mode will shut down to standby as soon as the 12 volt trigger signal is removed.

Rotel amplifiers that include signal sensing will shut down to standby approximately 5 minutes after no input signal or 12 volt trigger is present.

One exception is the RKB-850/8100 series amplifiers. On the RKB amplifiers, 12 volt trigger shutdown is instant, while signal sense will shut down after 10 minutes of no input signal.
