HIGH LEVEL INPUT
The HIGH LEVEL INPUT (Fig. 1, 1) is suitable to connect the amplifier inputs with speaker wires, if
your headunit is not equipped with pre-amplifier RCA outputs. Extend therefore every regarding speaker
cable from your headunit 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 like described below.
NOTE: Never use the HIGH LEVEL INPUT and the RCA inputs at the same time. This may damage
the amplifier seriously. The loudspeaker cables of the HIGH LEVEL INPUT must have no contact to the
ground (GND).
AUTO TURN ON
The amplifier detects a voltage rise (6 Volts) with a so called "DC Offset" over the connected input
signal on the HIGH LEVEL INPUT (Fig. 1, 1) when the headunit will be switched on. Hence, the amplifier
will also be turned on. As soon as the headunit will be turned off, the amplifier turns also automatically
off. In this case the turn-on connection (REM, Fig. 2, 2) is not needed.
Note: The Auto Turn On function usually works with 90% of all headunits, because they are equipped
with "High Power"-outputs. Only with a few older and still existing headunits the Auto Turn On function
is not working.
LOUDSPEAKER CONNECTIONS
- In 2-channel operation (i.e. one loudspeaker on each amplifier channel), the impedance must
not be lower than 2 ohms for each speaker
- In bridging mode (two amplifier outputs combined) the impedance must not be lower than 4 ohms
for the bridged output.
- Never connect loudspeaker cables with the ground of the chassis or the +12 V supply voltage.
If the amplifier is operated with a too low impedance or incorrectly used, the entire sound system
may be damaged. This means a warranty void in such cases.
SIGNAL OUTPUTS TO CONNECT AN ADDITIONAL AMPLIFIER
Due to its compact design, the amplifier has no signal outputs to supply additional amplifiers, such as
a mono subwoofer amplifier. Split in this case the input signal with a suitable Y-connector to provide
the input signal to both amplifiers.
OPERATING ELEMENTS
INPUT SENSITIVITY
Turn the input level control (LEVEL INPUT, Fig. 1, 3) on the amplifier to the MIN. position. Turn then
the volume control of the headunit to 80% - 90% of its maximum volume. Now turn slowly the input
level control on the amplifier (LEVEL INPUT, Fig. 1, 3) in a clockwise direction until you hear some
distortion, then turn back slightly until the distortion is not audible anymore.
