AUDIO SIGNAL CABLES
When installing the audio cables between the RCA outputs of the headunit 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 LINE 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 INPUT LEVEL (Fig. 1,8) controller of the amplifier to the MIN position. Then turn the volume controller
of the headunit to 80 - 90% of its full setting. Now turn INPUT LEVEL clockwise until you hear some distortion.
Then turn back the INPUT LEVEL slightly until you hear a cleaner sound.
VARIABLE HIGHPASS FILTER
If the amplifier is to be used for mid-range/tweeter loudspeakers, set the switches X-OVER (Fig. 1,3) to HIGH
PASS. Then set the desired cross-over frequency on the HIGH PASS controller (Fig.1,2). Thus to that only the
frequencies above the chosen cross-over frequency will be amplified. This effectively minimizes distortions and
overloads at lower frequencies. A good point to start is at 125 Hz.
If you use loudspeakers (>20 cm) set X-OVER (Fig.1,3). to "FULL". In this case, the HIGH PASS controller are
without function (Fig.1,2).
VARIABLE LOWPASS FILTER
If the amplifier is used to drive a subwoofer, set the switch (Fig. 1,3) to „LOW PASS". Set the desired cross-
over frequency by using the controller (Fig. 1,4). Thus to that only the frequencies below the chosen cross-over
frequency will be amplified and the subwoofer plays more precised and efficient.
VARIABLE BASS BOOST
By using the BASS BOOST controller (Fig.1,7) you are able to increase the bass enhancement from 0 to 12
dB. Attention: Use the BASS BOOST wisely!
PROTECTION CIRCUIT
The POWER/PROTECTION LED (Fig. 1,1) lits up green, if the amplifier is in operation.
The POWER/PROTECTION LED (Fig. 1,1) lits up red, when the amplifier is overheated, or a short circuit
occurs resp. a too low impedance load is connected to the speaker outputs. If this events, the internal built-in
protection circuit shuts down the amplifier automatically. The amplifier should work again properly after you
have solved the problems.
