AUDIO SIGNAL CABLES
When installing the audio cables between the RCA outputs of the head unit and the RCA inputs of the amplifier
[ 7 ], 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.
HIGH LEVEL INPUTS & AUTO TURN ON
The high level inputs under HI LEVEL INPUT [ 8 ] 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 amplifier. 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.
AUTO TURN ON
Push the AUTO TURN ON switch [ 9 ] to ON position. The amplifier detects now a voltage rise (6 Volts) over
the connected input signal on the HI LEVEL INPUT [ 8 ] 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 [ 3 ] is not needed.
NOTE: The AUTO TURN 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 Turn On function is not
working.
INPUT SENSITIVITY
Turn the LEVEL [ 10 ] 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 LEVEL [ 10 ] clockwise until you hear some distortion. Then turn
back LEVEL [ 10 ] slightly until you hear a cleaner sound.
