If the POWER/PROTECT is blue, the amplifier is ready for operation. If the POWER/PROTECT is red, there is a malfunction.
6
Refer in this case to the section TROUBLE SHOOTING.
Connect the INPUT RCA jacks with the head unit by using appropriate audio signal cables.
7
The OUTPUT RCA jacks provide a linear full-range audio signal for driving additional amplifiers.
8
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).
If your head unit does not have a turn-on signal (REM), you can use the automatic turn-on function of the amplifier. This works
10
in two ways, which can be set at the AUTO TURN-ON switch:
DC: This method only works if you use the amplifier's HIGH LEVEL INPUT. The amplifier then detects a voltage rise to 6 volts
when the head unit is turned on by a so-called "DC offset" and then turns on the amplifier.
VOX: Select this method when using the INPUT RCA jacks. The amplifier then detects a voltage increase in the incoming audio
signal when switching on the head unit via the attached RCA cable and then switches on the amplifier.
Note: As soon as the head unit is switched off again, the amplifier switches itself off.
The terminal for the amplifier turn-on (page 15#2, REM IN/OUT) can now be used to supply additional amplifiers with a turn-on
signal. Simply connect the REM terminals of the two amplifiers and make sure that the other amplifier is in "normal" turn-on
mode, which means that the AUTO TURN ON function is disabled.
11 The PHASE SHIFT controller allows to adjust the phase between 0° and 180°. Hence, you are able to adjust the subwoofer
perfect to the vehicle's acoustics.
The SUB SONIC controller limits the ultra low and not audible frequencies of the audio signal downwards to avoid mechanical
12
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. Is this controller adjusted higher that the LOW PASS controller, no sound is audible.
The LOW PASS controller determines the frequency cut-off upwards. The crossover frequency is continuously variable from 40
13
Hz to 150 Hz.
