The +12 V amplifier connection must then be connected with a power cable
possessing an integrated fuse to the battery's plus pole. The fuse must be located close
to the battery, the length of cable from the battery's positive pole to the fuse must be
less than 60 centimetres for safety reasons. Only insert the fuse when all installation
work, including the connection of the loudspeakers, has been completed.
Now connect the car hi-fi receiver's remote control connection to the amplifier's REM
control jack. A cable with a cross-section of 0.75 mm
amplifier's REMOTE connection and the control device.
4.2 LOUDSPEAKER CONNECTIONS
• In normal operating mode (i.e. one loudspeaker on each individual amplifier
channel), the lowest terminal resistance is 2 ohm per channel.
• In bridging mode (two amplifier outputs combined) the lowest terminal resistance
doubles to 4 ohm.
• The impedance in tri-mode may not fall below 2 ohm per channel.
• Never connect the loudspeakers' minus terminals to the vehicle chassis.
• Never connect the +12 V supply voltage to a loudspeaker output as this would
destroy the amplifier final stage.
If the amplifier is operated with lower terminal resistances or incorrectly used as
described above, both the amplifier and the loudspeakers may be damaged. The
warranty becomes void in such cases.

OPERATING ELEMENTS AND IN/OUTPUTS
5.1 SETTING THE INPUT SENSITIVITY
The input sensitivity may be adapted to any car radio or tape deck. Turn the volume
control of your radio to its central position and then adjust the input-level control (3) to
produce an average medium volume. This setting usually provides sufficient power re-
serves at optimum weighted noise voltage.
ATTENTION: only reproduce loud test noises briefly to prevent damaging the
loudspeakers.
