AUDIO SIGNAL CABLES
WheninstallingtheaudiocablesbetweentheRCAoutputsoftheheadunitandtheRCAinputsoftheamplier,
the audio and power supply cables should, if possible, not be routed along the same side of the vehicle. We
recommend a separated installation, e.g. routing the power cable through the cable channel on the left side
and the audio cables through the cable channel of the vehicle on the right side or vice versa. This prevents
interferences due to crosstalk into the audio signal.
SIGNAL OUTPUTS TO CONNECT ADDITIONAL AMPLIFIERS
The input signal on the INPUT jacks (Fig. 1,8) will be routed in stereo to the output jacks OUTPUT (Fig. 1,7).
ThustheOUTPUTjackallowstheconnectionofaadditionalamplier.
INPUT SENSITIVITY
OPERATING ELEMENTS
TurntheLEVEL(Fig.1,6)controlleroftheampliertotheMINposition.Thenturnthevolumecontrollerofthe
headunit to 80 - 90% of its full setting. Now turn LEVEL clockwise until you hear some distortion. Then turn back
the LEVEL slightly until you hear a cleaner sound.
VARIABLE SUBSONIC FILTER
WiththeSUBSONICcontroller(Fig.1,4)youcanadjustthelowercross-overfrequency,toltertheverylow
frequencies to relieve the subwoofer or to generate a bandpass signal. If you don’t want to use this function,
turn the controller (Fig. 1,4) to the very left to the 15 Hz position.
NOTE: The adjusted value of the SUB SONIC (Fig. 1,4) should not be higher than the adjusted value of the
LOW PASS controller (Fig. 1,5). Otherwise no sound will be hearable.

impedance load is connected to the speaker outputs. If this events, the internal built-in protection circuit shuts
downtheamplierautomatically.Theampliershouldworkagainproperlyafteryouhavesolvedtheproblems.
VARIABLE LOW PASS FILTER
Set the desired cross-over frequency by using the controller (Fig. 1,5). Thus to that only the frequencies below
thechosencross-overfrequencywillbeampliedandthesubwooferplaysmoreprecisedandefcient.
BASS LEVEL REMOTE CONTROLLER
With the included bass level cable remote controller you are able to adjust the bass level e.g. out of the drivers
seat.
VARIABLE BASS EQ
With the bass boost controller (Fig.1,3) you are able to adjust the bass level from 0 - 12 dB at 45 Hz.
Attention: Use the BASS EQ wisely!
