XLf 200 A

Voltage supply

We recommend a minimum cross section of 2.5 mm

Route commercially available plus cables to the battery

and connect via fuse holder.

Use cable glands for holes with sharp edges.

Securely fasten commercially available minus cables to a

noise-free earth point (chassis screw, chassis metal) (not

to the minus pole of the battery).

Scrap the contact surfaces of the earth point until they

are bright and grease with graphite grease.

Connection

; is connected to the positive pole of the

battery and connection : to negative vehicle ground. The

control of the XLf 200 A should ideally be a two-channel con-

trol, either via the preampli er outputs or the loudspeaker

outputs of the car sound system. A control solely via the right

or left channel is also possible since the low-frequency por-

tion of the music is generally identical on both channels.

Integrated fuse

The fuse integrated in the ampli er protects the output stage

and the entire electrical system in case of a malfunction. If a

replacement fuse is used, never bridge fuses or replace them

with a type with higher current.

Audio inputs

You can select between 2 di erent audio inputs;

Cinch (RCA)

Hi level (loudspeaker connections)

Use only one of the audio inputs; otherwise, it may lead to

audio interferences.

The preampli er outputs are connected to the cinch (RCA)

sockets

2 of the subwoofer box via a shielded sound cable.

With control via the loudspeaker outputs, the input connec-

tions of pos.

8/9 are fed to the closest loudspeaker cables

(front or rear) on the left and right. They are separated and

connected to the input connections. The polarity of the

+ or – connections must be observed. Bridge output stages

(BTL) can also be connected directly without an additional

adapter.

Switching on/o

A special feature of the XLf 200 A is its automatic switch-on:

The subwoofer box automatically switches on if a music

signal is received. If no music signal is received for more than

60 seconds, the XLf 200 A automatically switches o .

VOL control

The VOL control 4 is used to adjust the input sensitivity of

the power ampli er to the output voltage of your car sound

system preampli er output.

The adjustment range is from 0.1 V to 7.5 V.

If a car sound system of a third party manufacturer is con-

nected, the input sensitivity must be adjusted corresponding

to the manufacturer data.

–

A few important explanations in this context:

By turning the control clockwise, the input sensitivity of the

ampli er and, therefore, also the volume increases. However,

this is not a volume control; no further ampli er output

can be achieved in the end position, even if it may sound

like that at the beginning. The system merely increases the

volume faster if the volume control of the car sound system

is turned up.

CROSSOVER frequency control

The CROSSOVER control 5 allows setting the desired entry

frequency.

Example:

At a setting of 150 Hz, the ampli er has a frequency range

of 20 Hz to 150 Hz.

Settings

The following control setting is recommended as basic

setting before putting the device into operation: Sensitiv-

ity (VOL) Pos. 4 to minimum, PHASE Pos. 6 to 0°,  lter

(CROSSOVER) Pos.

5 to approx. 80 Hz. Switch on the device

and select a musical piece with distinctive bass playback.

Increase the volume of your car sound system to the desired

volume level. Now slowly increase the VOL control

4 until

you can hear a clear ampli cation of the bass level. Next,

use the CROSSOVER control 5 to select a  lter setting that

provides a well-contoured bass. You may have to alternately

optimise the sensitivity setting 4 and the  lter setting 5.

A droning bass with excessive volume requires a  lter setting

with a low frequency.

The phase switch

6 must be set so that the bass is inte-

grated into the acoustic pattern as best as possible and not

recognisable as an individual source.

Also check your settings of the XLf 200 A with the bass con-

trol fully open and, if necessary, with activated loudness. An

overloading of the subwoofer box by selecting an excessive

ampli cation (pos.

4) results in a distorted playback and can

damage the loudspeaker.

Power-on indicator (PRT/PWR)

Green LED:

Output stage on, regular operating status.

Red LED:

Output stage is electronically switched o due to an error.
