very low frequencies reproduced by the sub-
woofer . However, do not place it too close
to walls or in corners; this would distort the
frequency response .
Prior to making connections or changing any
existing connections, switch off the amplifier
module and the units to be connected .

4.1 Connecting a signal source

Connect a signal source with line level (e . g . out-
put of a mixer or preamplifier) to the RCA jacks
LINE IN (8) . When connecting a stereo signal
source, a mono signal is internally created . It is
also possible to connect the jack L / LFE to an LFE
output . In multi-channel systems for cinema ap-
plications, e . g . "5 .1", the LFE channel is used for
low-frequency special effects ("Low Frequency
Effect" or "Low Frequency Enhancement") .

4.2 Signal output

At the RCA jacks LINE OUT (9), the input signal
is available for being routed to another amplifier
or active speaker system . The position of the
controls LEVEL (5), CUT OFF (6) and PHASE (7)
has no effect on this output signal .

4.3 Power supply

Connect the mains cable provided to the
mains jack (2) and the plug to a mains socket
(230 V/ 50 Hz) .

5 Operation

CAUTION Never adjust the speaker system
to a very high volume . Permanent
high volumes may damage your
hearing! Your ear will get accus-
tomed to high volumes which do
not seem to be that high after
some time . Therefore, do not fur-
ther increase a high volume after
getting used to it .
Note: To prevent switching noise, always switch on
the signal source connected before switching on the
amplifier module . After use, switch off the amplifier
module first .
1) Before switching on for the first time, set the
LEVEL control (5) to minimum (left stop) for
the time being . Switch on the amplifier with
the POWER switch (1) . As long as no signal
is applied, the module is on standby to save
power and the LED STANDBY/POWER (4)
shows red . As soon as a signal is applied, the
power amplifier is switched on and the LED
shows green .
2) Via the existing speaker system, reproduce
music, for example, and add the desired low
bass part with the LEVEL control (5) . Only
turn up the control to such an extent that the
sound reproduced is not distorted .
3) Use the control CUT OFF (6) to set the upper
cut-off frequency of the subwoofer in such
a way that it will optimally complement the
frequency response of the other speakers .
4) When the speakers are placed at different
distances to the listener, phase cancellation
may result (certain frequencies are repro-
duced at a lower volume) . To compensate
this effect, shift the phase of the subwoofer
signal with the control PHASE (7) .
Test the positions of the control to find
the one offering the bass reproduction of
the highest volume at the listening position .
Then readjust the volume balance with the
LEVEL control (5), if required .
5) If there is no signal at the input for more than
approx . 25 minutes, the amplifier module goes
on standby: The LED STANDBY/ POWER (4)
shows red . If the amplifier module is not in
use for longer intervals, switch off the ampli-
fier module with the POWER switch .
