Connect the INPUT RCA jacks with the head unit by using appropriate audio signal cables.

The OUTPUT RCA jacks provide a linear full-range audio signal for driving additional amplifiers.

If your head unit does not have RCA preamp outputs, you can use the amplifier's HIGH LEVEL INPUT as the signal input. To do
this, simply connect the loudspeaker cables of the head unit to the enclosed cable plug as follows:

The LEVEL INPUT controller determines the input sensitivity (adaptation to the output signal of the head unit). The controller
9
range is between 5 volts (MIN) and 0.2 volts (MAX).
The SUB SONIC controller limits the ultra low and not audible frequencies of the audio signal downwards to avoid mechanical
10
and electrical overloading on the subwoofer. The cut-off frequency is adjustable from 10 to 40 Hz and depends on the size of
the subwoofer.
If the POWER/PROTECT is blue, the amplifier is ready for operation. If the POWER/PROTECT is red, there is a malfunction.

Refer in this case to the section TROUBLE SHOOTING.

The LOW PASS controller determines the frequency cut-off upwards. The crossover frequency is continuously variable from 40
Hz to 150 Hz (5 kHz).
