Unpacking

The carton and packing materials used in shipping your new amplifier were specially designed to cushion it from the shocks and vibration of shipping.We strongly suggest that you save the carton and packing materials to use if you move, or if the unit ever needs to be shipped back to us for any reason. To minimize the size of the carton in storage, you may wish to flatten it by carefully opening the top and bottom flaps and folding the carton flat. Other cardboard inserts may be stored in the same manner. Packing materials that cannot be collapsed should be saved along with the carton in a plastic bag.

1 3-Color LED Status Indicator The front panel LED indicator has three modes:

Amber: Indicates the SA-180 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-180 is on and operational.

Red: Indicates the SA-180 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-180 or another component in your system. In this case disconnect the SA-180 from AC power and the rest of your system and consult Atlantic Technologies Customer Service Department for assistance.

2 BASS LEVEL control Sets the volume level of the connected subwoofer.A detent setting is provided for reference level operation.

3 phase control Sets correct subwoofer phase (0? or 180?) to best match your satellite speakers and room.
