AUDIO SIGNAL CABLES
When installing the audio cables between the RCA outputs of the head unit and the RCA inputs of the amplifier,
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. 1.6) will be routed in stereo to the output jacks OUTPUT (Fig. 1.5).
Thus the OUTPUT jack allows the connection of a additional amplifier.
OPERATING ELEMENTS
INPUT SENSITIVITY
Turn the GAIN (Fig. 1.9) controller of the amplifier to the MIN position. Then turn the volume controller of the
head unit to 80 - 90% of its full setting. Now turn GAIN clockwise until you hear some distortion. Then turn back
the GAIN slightly until you hear a cleaner sound.
VARIABLE HIGH PASS FILTER
If the amplifier is to be used for mid-range/tweeter loudspeakers, set the switches CROSSOVER (Fig. 1.3) to
HPF. Then set the desired crossover frequency on the HPF controller (Fig.1.2). Thus to that only the frequen-
cies above the chosen crossover frequency will be amplified. This effectively minimizes distortions and over-
loads at lower frequencies. A good point to start is at 125 Hz.
If you use loudspeakers (>20 cm) set CROSSOVER (Fig.1.3). to "FULL". In this case, the HPF controller are
without function (Fig.1.2).
VARIABLE LOW PASS FILTER
If the amplifier is used to drive a subwoofer, set the switch (Fig. 1.3) to „LPF". Set the desired crossover
frequency by using the controller (Fig. 1.4). Thus to that only the frequencies below the chosen crossover
frequency will be amplified and the subwoofer plays more precisely and efficient.
SWITCHABLE BASS BOOST
By using the BASS BOOST switch (Fig.1.8) you are able to increase the bass enhancement by 6 or 12 dB.
Attention: Use the BASS BOOST wisely!
SWITCHABLE TREBLE BOOST
By using the TREBLE BOOST switch (Fig.1.7) you are able to increase the treble enhancement by 6 or 12 dB.
Attention: Use the TREBLE BOOST wisely!
BASS LEVEL REMOTE
With the included remote, the bass level can be adjusted e.g. from the driver's seat. Connect the remote at
the REMOTE terminal (Fig. 1.10) with the included cable. The remote should only be used when operating the
amplifier in LPF mode with a subwoofer.
