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 use asdescribed above, both
the amplifier an the loudspeakers may be damaged. The warranty becomes void in such cases.
Operating Elements and In/Outputs
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)(13) to produce an
average medium volume. This setting usually provides sufficient power reserves at optimum
weighted noise voltage.
Attention: Only reproduce loud test noises briefly to prevent damaging the loudspeakers.
Low-Pass Filter with adjustable Cross-Over Frequency
If the amplifier is used as a subwoofer amplifier, set the switch (4)(12) to "LPF".
Set the desired Cross-over frequency with the control (7)(9). This makes the filter adaptable to
the installed woofers sound requirements. The filters high edge steepless is responsible for
the precise of medium an high frequency ranges.
High-Pass Filter with adjustable Cross-Over Frequency
If the amplifier is to be used as an amplifier for satellite loudspeakers (mid-range/tweeter
Loudspeakers), set switch (4)(12) to "HPF". Set the desired cross-over frequency with the
Control (5)(11), only the frequencies above the set cross-overfrequency will then be amplified.
This effectively minimizes distortions caused by excessive membrane movement at low
frequencies and small stellite loudspeakers without reducing the bass level.
Bass-Boost
The bass-boost function (6)(10) is used to increase or equalize the lower bass frequencies.
High Level Input
This unit can be connected to any car stereo with high level outputs, Common or separated
Ground outputs.
Note: Do not connect these high level input wires if you are using the low level input RCA jacks.
Otherwise it result in damage to the amplifier and other units in the set up.
