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 mm²

is sufficient for connecting the amplifier’s remote connection and the control device.

4.2 auDio CaBles

when installing the audio cable between the cinch output of your car receiver and the cinch input of the amplifier inside your car, the

audio and power supply cables should, wherever possible, not be routed along the same side of the vehicle. we recommend an isolated

installation, e.g. routing the power cable through the cable duct on the left-hand side and the audio cable through the cable duct on the

right-hand side or vice versa. this reduces interference due to crosstalk into the audio cables.
this also applies to the connecting cable for the remote control for regulating the volume. this cable should not be laid on the side of the

power supply leads but together with the audio cable.

4.3 louDspeaKer ConneCtions

the lowest terminal resistance is 1 ohm

when two mAGnAt Power Core one Limited amplifiers in master/slave mode are bridged the smallest terminating resistance is

2 ohm.

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.

5. 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 (4) 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.

5.2 low-pass filter with aDJustaBle Cross-over frequenCY

Set the desired cross-over frequency with the control (5). this makes the filter adaptable to the installed woofer’s sound requirements. the

filter’s high edge steepness is responsible for the precision reduction of medium and high frequency ranges.

5.3 suBsoniC filter

the subsonic function reduces the lowest bass frequencies. the reduction rate may be infinitely adjusted with the regulator (6). this

allows distortions produced by excessive loudspeaker membrane movements to be effectively minimized without reducing the utilizable

bass levels.

5.4 Bass-Boost

the bass-boost function (7) is used to increase or equalize the lower bass frequencies.

5.5 volume remote Control

the volume may be adjusted by using the supplied remote control (11). Please observe during installation that the remote control line

shouldn’t be routed along the same side of the vehicle as the power supply cables. the remote control unit should be mounted on the

dashboard or at any other easily accessible position. now, the subwoofer volume may be adjusted independently from the settings at the

radio.

5.6 outputs for ConneCting aDDitional amplifiers / master/slave moDe

in master/slave mode, two amplifiers are controlled by one audio source at the same time. in this case, the slave amplifier adopts the

volume and filter settings of the master amplifier.
in master/slave mode, the „master“ amplifier‘s preamp output signal (mASter oUt (2)) is added to the “slave” amplifier’s amplifier input

(SLAVe in (1)), see also fig. 4a and b. to this end, the switch (9) on the „master“ amplifier (A) must be set to „mASter oUt“, the switch

(9) on the „slave“ amplifier (B) to „SLAVe in“.

5.7 phase regulator

the phase regulator (8) is for optimizing the phase response and frequency response between subwoofer and satellites.
