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 (Figure 32) .
Attenuation Controls
The controls are marked with a scale indicating attenuation. Maximum attenuation is fully counter clockwise, minimum attenuation is fully
clockwise.
(Figure 33) .
LED Indicators
The green SIGNAL LED indicators light at approximately 0.1% of full power.
The red CLIP LED indicator fl ashes during overload (clipping).
If the amplifi er's protection circuitry triggers protective muting, the signal and clip LEDs will not light. If this occurs during use, see the Troubleshooting
section on page 17 — page 18.
