AUDIO SIGNAL CABLES
When installing the audio cables between the RCA outputs of the head unit and the RCA inputs of the amplifier
[ 6 ]
, 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.
AUTO ON
Push the AUTO ON switch
[ 8 ]
to ON position. The amplifier detects now a voltage rise (6 Volts) over the con-
nected input signal on the HI LEVEL IN
[ 7 ]
when the head unit will be switched on. Hence, the amplifier will
also be turned on. As soon as the head unit will be turned off, the amplifier turns also automatically off. In this
case the turn-on connection
[ 5 ]
is not needed.
NOTE:
The AUTO ON function usually works with 90% of all head units, because they are equipped with ”High
Power”-outputs. Only with a few older and still existing head units the AUTO ON function is not working.
HIGH LEVEL INPUTS & AUTO ON
The high level inputs under HI LEVEL IN
[ 7 ]
is suitable to connect the device input with speaker wires, if your
head unit is not equipped with pre-amplifier RCA outputs. Extend therefor every regarding speaker cable from
your head unit with appropriate speaker cables from your car audio retailer to the mounting location of the am-
plifier. Then connect the each matching loudspeaker cable with the cables of the included High Level Input jack.
CAUTION: Never use the high level inputs and the RCA inputs at the same time. This may damage the
device seriously. Use the enclosed cable plug to connect each terminal.

INPUT SENSITIVITY
Turn the INPUT GAIN
[ 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 INPUT GAIN
[ 9 ]
clockwise until you hear some distortion.
Then turn back INPUT GAIN
[ 9 ]
slightly until you hear a cleaner sound.
