CAUTION Never adjust a very high volume. Per-
manent 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 further increase a
high volume after getting used to it.
Note: To prevent switching noise, always switch on
the signal sources connected before switching on
the subwoofer. When switching off, proceed in the
reverse order.
1) Prior to initial operation, set the controls SUB
LEVEL (2), LINE LEVEL (9) and MIC LEVEL
(12) to minimum (left stop) for the time being.
For basic setting, set the tone controls TREBLE
(3) and BASS (4) and the balance control BAL
(5) to mid-position.
2) Switch on the unit with the POWER switch (18).
The switch is illuminated.
3) If a signal source is connected to the LINE
INPUT (10, 13), adjust the desired volume with
the control LINE LEVEL (9). Only turn up the
control to such an extent that the sound repro-
duced is not yet distorted and the LED CLIP L /R
(7) does not yet light up.
4) If a microphone is connected, add its signal to
the mix with the control MIC LEVEL (12). If
required, reduce the level of the line signal with
the control LINE LEVEL (9).
CAUTION! To prevent feedback noise, do not
point the microphone towards the speaker and
do not hold it too close to it. Feedback noise may
also occur when the volume is too high. In this
case, or if the LED CLIP L / R (7) lights up,
reduce the microphone volume with the control
MIC LEVEL (12).

5) Adjust the sound with the two controls TREBLE
(3) and BASS (4). Add the desired low bass part
to the mix with the volume control of the sub-
woofer SUB LEVEL (2). Only turn up the control
to such an extent that the sound is not yet dis-
torted. If the LED CLIP SUB (6) lights up, it is an
indication for overload of the subwoofer ampli-
fier. In this case, turn back the control accord-
ingly or reduce the volume of the input signal.
Use the control XOVER FREQ (1) to set the
crossover frequency (80 – 250 Hz) in such a way
that the subwoofer ideally complements the
sound of the stereo speakers connected.
6) If required, readjust the volume balance of the
stereo speakers with the control BAL (5).
7) After use, switch off the subwoofer system with
the POWER switch.
