Voltage supply
-
We
recommend a
minimum
cross section
of
2.5
mm
2
•
- 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
C
!0
to
negative vehicle ground. The
control
of
the XLf
200
A
should ideally
be a two-channel con-
trol,
either via the preamplifier
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
amplifier 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 different audio inputs;
- Cinch
(RCA)
-
Hi level (loudspeaker connections)
Use
only one
of
the audio inputs; otherwise,
it
may
lead
to
audio interferences.
The
preamplifier outputs are connected
to
the cinch
(RCA)
sockets
(
~
)
of
the subwoofer box
via
a shielded sound
cable.
With control via
the
loudspeaker outputs, the
input
connec-
tions
of
pos.
(~)!

~
:::
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/off
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.lf no music signal
is
received for more than
60
seconds,
the
XLf
200 A automatically switches off.
VOL
control
The
VOL
control
C
~
)
is
used
to
adjust the
input
sensitivity
of
the power
amplifier
to
the
output
voltage
of
your car sound
system preamplifier
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
amplifier and, therefore,
also
the
volume
increases. However,
this
is
not
a
volume
control; no
further
amplifier
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
/

-
~:
allows
setting
the
desired entry
frequency.
Example:
At a setting
of
150
Hz,
the
amplifier
has
a frequency range
of
20
Hz
to
1
50
Hz.
Settings
The
following
control
setting
is
recommended
as
basic
setting before
putting
the
device
into
operation: Sensitiv-
ity

(CROSSOVER)
Pas.
(s)
to
approx.
80Hz. 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 until
you can hear a clear amplification
of
the
bass
level. Next,
use
the
CROSSOVER
control
(s
::
to
select a
filter
setting
that
provides a well-contoured
bass.
You
may have
to
alternately
optimise the sensitivity setting and
the
filter
setting
(
~
}
A droning
bass
with
excessive volume requires a filter setting
with
a
low
frequency.
The phase switch
C
~
)
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
amplification
(pos.
c

:::
)
results
in
a distorted playback and
can
damage
the
loudspeaker.
