5.2 Signal output

The signal of the line inputs (10, 13) is available at
the RCA jacks PAR . LINE OUTPUT (14) . They can
be used e . g . to connect another sound system
or a recorder .

5.3 Stereo speakers

Connect two speaker systems for mid-high
range reproduction with a minimum impedance
of 8 Ω, e . g . PAB-306, to the speaker jacks (17)
OUTPUT LEFT (left speaker) and OUTPUT RIGHT
(right speaker) . The configuration of the plug is
shown in figure 4 (page 11) . When several
speakers are interconnected at an output, the
total impedance of the speakers must not fall
below 8 Ω at any output .
After connecting a speaker plug to the jack,
turn the plug clockwise until it engages . To dis-
connect the plug, pull back the locking tab of the
plug and turn the plug counter-clockwise .
When connecting the speakers, make sure
that both speakers have the same polarity .

5.4 Power supply

Connect the mains cable provided to the
mains jack (20) and the plug to a mains socket
(230 V / 50 Hz) .
6 Operation
CAUTION Never adjust a very high vol-
ume . Permanent high volumes
may damage your hearing! Your
ear will get accustomed 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 sub-
woofer . 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 reproduced
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, never
point the microphone towards the speaker and
never 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 subwoofer SUB LEVEL (2) . Only turn up
the control to such an extent that the sound
is not yet distorted . If the LED CLIP SUB (6)
lights up, it is an indication for overload of the
subwoofer amplifier . In this case, turn back the
control accordingly 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 .
