3-Color LED Status Indicator
The front panel LED indicator has three modes:
Amber: Indicates the SA-380 is connected to an AC power source
and the rear-panel Main Power switch is turned on. When the
indicator is amber, the unit is in the Standby mode and is ready
to turn on when a control signal is received at the trigger jack or
from the music sense circuitry.
Green: Indicates the SA-380 is on and operational.
Red: Indicates the SA-380 is in Protect mode. Turn the unit off
and check for the source of the condition that caused the overload.
This may be a shorted speaker lead or other similar condition. In
the event of repeated appearance of the red LED you may have a
chronic system failure with either the SA-380 or another compo-
nent in your system. In this case disconnect the SA-380 from AC
power and the rest of your system and consult Atlantic Technolo-
gies Customer Service Department for assistance.
