GAIN = INPUT LEVEL CONTROL

● The input level control allows the system to work well within a wide range of output level. 

Choose the adjustment in the way that you achieve a sound most possibly without any

distortion. As a guideline the following procedure is recommended:

   –If you use several amplifiers, the adjustment has to be made for each set separately. 

Tune in the volume of your car radio to 2/3 of the maximum volume. Now turn the gain 

control of the amplifier from "Min" to "Max" direction until you can hear distortions. Then turn

the gain a little back until the noise disappear. The gain control adjustment is finished now.

ATTENTION: 

If you use 2 Ohm speakers in stereo mode, or 4 Ohm speakers in bridge mode 

and the overload protection is triggered out, turn the gain control to "Min" direction, until 

the operation is free of trouble.

X-OVER FREQUENCY CONTROL

● When the crossover control is in the Low-Pass position, this control becomes active

allowing you to select your crossover point. 

● When the crossover control is in the High-Pass position, this control becomes active 

allowing you to select your crossover point.
