1:Power switch - Use this to power the Servo Amplifier on or off.

2:Channel input controls (left/right) - These 41-position knobs allow you to

adjust the input level of the signal arriving at the rear-panel input jacks. At the fully counterclockwise position (labeled “∞ ”), the signal is infinitely attenuated (completely off). At the fully clockwise position (labeled “MAX”), the signal is at unity gain (that is, no attenuation). When 0 dBu of signal arrives at the input jacks and the Channel Input controls are set to their “MAX” position, the Servo Amplifier delivers full power output.

3:Protection light - This light goes on for approximately five seconds when- ever the Servo Amplifier is powered on and fades slowly when the amp is pow- ered off. When lit, 0 volts DC are provided to all connected speakers, thus mut- ing them and preventing any “thump” from occurring. For a complete description of the conditions under which this light goes on, see Appendix D (“The Servo Amplifier Protection Circuitry”) on page 12 of this manual.

4:Clip lights (left/right) - These lights go on whenever the signal being input to the corresponding channel rises to a distortion level above .03% THD.

5:Idle lights (left/right) - These lights go on whenever signal is present at the corresponding input. They go off when no signal is present.
