NOTE: Some products cannot detect ANALOG signal inputs and
the unit may power off if there is no digital audio source detected or
user action with the remote control or front panel. Analog input signal
detection is not available in all models which may cause the unit to
inadvertently power off. In this case the Off Timer should be set to

• SIGNAL SENSE: Check if an audio signal is present on the configured
Signal Sense input. The A12 monitors the data stream to determine if
there is audio. If there is no audio detected for 10 minutes, the A12 will

the A12 detects audio on Signal Sense input, the unit will automatically
power on. To disable this function, select the OFF option which is the
factory default setting.
NOTE: Recent software versions allow the configured Signal Sense
input to be active in Standby Mode regardless of source input active
when the unit was powered off to standby. Previous version of software
required the Signal Sense configured input to be the active source when
the unit was powered off for Signal Sense to become active and monitor
the configured input for audio. For more information and details on
supported software versions and software update steps please contact
your authorized Rotel dealer.
NOTE: When the SIGNAL SENSE function is activated the A12 will
consume additional power in signal sense standby mode.
