Make sure you connect the amplifier to the correct AC line voltage, as shown on the serial number label. Connecting to the wrong line voltage is
dangerous and may damage the amplifier
Operation
AC Power Switch
Before applying power, check all connections and turn the attenuation controls fully counter clockwise to maximum attenuation.
One second of muting is normal when the amp is turned on or off
Attenuation Controls
The controls are marked with a scale indicating attenuation. Maximum attenuation is fully counter clockwise, minimum attenuation is fully

clockwise.
LED Indicators
The green SIGNAL LED indicators light at approximately 0.1% of full power.
The red CLIP LED indicator flashes during overload (clipping).
If the amplifier's protection circuitry triggers protective muting, the signal and clip LEDs will not light. If this occurs during use, see the Troubleshooting
