2 Safety Notes

This unit corresponds to all relevant directives of
the EU and is therefore marked with
WARNING The unit uses dangerous mains
voltage . Leave servicing to skilled
personnel only . Inexpert handling
or modification of the unit may
result in electric shock .
•
The unit is suitable for indoor use only . Protect
it against dripping water and splash water,
high air humidity and heat (admissible ambi-
ent temperature range 0 – 40 °C) .
•
Do not place any vessel filled with liquid on
the unit, e . g . a drinking glass .
•
The heat generated inside the unit must be
dissipated by air circulation . Do not cover the
air vent (bass-reflex opening) .
•
Do not operate the unit or immediately dis-
connect the mains plug from the socket
1 . if the unit or the mains cable is visibly dam-
aged,
2 . if a defect might have occurred after the
unit was dropped or suffered a similar
accident,
3 . if malfunctions occur .
In any case the unit must be repaired by skilled
personnel .
•
Never pull the mains cable to disconnect the
mains plug from the socket, always seize the
plug .
•
For cleaning only use a dry, soft cloth; never
use water or chemicals .

3 Applications

This compact active subwoofer is used as a
. low-frequency complement of existing audio
systems for hi-fi applications, home cinema and
home recording applications . It is equipped with
a 20 cm (8") bass speaker . Its amplifier offers a
peak output power of 90 W .
The subwoofer features an adjustable low
pass filter, a volume control, a phase reversal
switch and an automatic standby mode .
Two stereo inputs are available (each with a
feed-through output): one input for connection
to an output with line level and one input for
connection to a speaker output .

4 Setting Up and Connecting

Set up the subwoofer on a flat surface . It is
not important to place the subwoofer exactly
in the middle between the stereo speakers as it
will not be possible to precisely locate the very
low frequencies reproduced by the subwoofer .
However, do not place it too close to walls or
in corners; this would distort the frequency re-
sponse and prevent the heat dissipation of the
integrated amplifier . Likewise, do not cover the
bass reflex opening on the rear side .
Prior to making or changing any connec-
tions, switch off the subwoofer and the units
to be connected .
Connect a signal source via one of the two
connection options described in chapters 4 .1
and 4 .2 .

4.1 Stereo input LINE IN

If a stereo output with line level is provided (e . g .
output of a preamplifier or mixer), connect this
output to the input LINE IN (7) on the subwoofer .
From the two stereo channels, a mono signal will
be created internally for the subwoofer .
If the outputs of the preamplifier or mixer
are already used for the existing audio system,
use an adapter to divide the output signal (e . g .
ACA-120 from MONACOR) . As an alternative,
the feed-through output LINE OUT (8) can be
used to divide the output signal: Feed the output
signal of the preamplifier/mixer to the input LINE
IN (7) and then, via the output LINE OUT, route
it to the audio system .
