Adjusting the input sensitivity
To adjust the input sensitivity you have to remove the name plate on top of the amplifier with the included hexagon socket
screw key. Under this plate are the pushbuttons for precise and easy adjustment of the input sensitivity. Each channel can
be configured separately. The LED-indicator shows the adjusted input sensitivity of each channel. The controls are no vo

lume controls and are only for setting up the input levels of the amplifier to the output levels of the headunit or pre-amplifier.
1 Pushbutton for increasing the input sensitivity
With this control the input sensitivity of each channel can be increased stepwise.
2 Pushbutton for decreasing the input sensitivity
With this control the input sensitivity of each channel can be decreased stepwise.

The red shining LEDs indicate the adjusted input sensitivity. Please take care that the input sensitivity in bridged mode is
set up equally.
