Factory Default Settings

To return the amplifier to the factory default settings:

1. Unplug the power supply and then reconnect it.

2. The LED indicators will show a light pattern in the "Vol In" column. This

indicates the firmware revision. This will be followed by a green light

at the bottom of each column.

3. Within 20 seconds, press the On/Off button and Volume In (-) button

together, then release them.

4. The "Vol In" column will again indicate the firmware revision. This indi-

cates that the settings have been restored.
