s on
button • SIGNAL SENSE: Checks if a digital audio signal is present on the configured
Signal Sense input. When this input is selected as the active listening
source, the RA-1572 monitors the digital data stream to determine if
there is audio. If there is no audio detected for 10 minutes, the RA-1572
will enter Signal Sense Standby Mode. When in Signal Sense Standby
Mode and the RA-1572 detects audio on Signal Sense input, the unit
will automatically power on. To disable this function, select the DISABLE
option which is the factory default setting.
NOTE: To use the Signal Sense function, the RA‑1572 must be actively
listening to the configured Signal Sense source. If a source other than
the configured Signal Sense source is selected, the automatic power
off and power on functions will not be active. Example: if the Signal
Sense source is configured as COAX 1 and the unit is listening to OPT
2, the signal sense functions will not be activated.
NOTE: When the RA‑1572 enters standby mode via the remote
control, the Signal Sense function will not operate until the unit detects
the audio has stopped for the minimum 10 minute time‑out period. This
prevents the unit from immediately powering back on if there is still
active audio playing.
NOTE: When the SIGNAL SENSE function is activated, the RA‑1572
will consume additional power in signal sense standby mode.
• FACTORY DEFAULT: This sets the unit back to the original state as when
it left the factory. Press the + button on the front panel or RIGHT arrow
button on the remote control to select <YES> then press the "ENTER"
button on the front panel or on the remote control.
NOTE: All previously configured options will be erased and reset to
the factory default settings.

Troubleshooting

Most difficulties in audio systems are the result of incorrect connections,
or improper control settings. If you encounter problems, isolate the area
of the difficulty, check the control settings, determine the cause of the fault
and make the necessary changes. If you are unable to get sound from the
RA-1572, refer to the suggestions for the following conditions:

Power Indicator Is Not Illuminated

The Power Indicator ring around the power button and the basic items in the
Display window should be illuminated whenever the RA-1572 is plugged
into the wall power outlet and the POWER switch is pushed in. If it does not
light, test the power outlet with another electrical device, such as a lamp.
Be sure the power outlet being used is not controlled by a switch that has
been turned off.

Fuse Replacement

If another electrical device works when plugged into the power outlet, but
the Power Indicator still will not illuminated when the RA-1572 is plugged
into the wall outlet, it indicates that the internal power fuse may have blown.
If you believe this has happened, contact your authorized Rotel dealer to
get the fuse replaced.
