5.5.2 Outputs
The amplifier is able to operate two speakers or
two speaker groups . In bridge operation, the
minimum impedance of the speakers or the min-
imum total impedance of the speaker groups
must be 8 Ω and the minimum power capability
500 W RMS . Connect the speakers or speaker
groups to the output jacks (14):
CH 1+ = positive pole of speaker 1
CH 2+ = negative pole of speaker 1
CH 3+ = positive pole of speaker 2
CH 4+ = negative pole of speaker 2
5.6 Bi-Amping
In the Bi-Amping mode, the power amplifiers
build an active 2-way stereo system (fig . 8) . For
this purpose, the mid-high range speakers and
the bass speakers are separately connected to
the power amplifiers . For this operating mode,
set the switches (8) on the rear panel of the
unit as follows:

5.6.1 Inputs
Connect the output of the line source (e . g .
preamplifier, mixer, etc .) to the inputs of the
amplifier:
Connect the left channel to the input jack CH 1
and the right channel to the input jack CH 2 .
The XLR jacks (12) or the 6 .3 mm jacks (13) can
be used as inputs . The inputs CH 3 and CH 4 are
not connected .
5.6.2 Outputs
The amplifier is able to operate four speakers or
four speaker groups . The highest output power
is obtained when connecting 4 Ω speakers and
speaker groups with a total impedance of 4 Ω
each . However, it is also possible to connect 8 Ω
speakers or speaker groups with a total imped-
ance of 8 Ω . In this case, the output power will be
slightly reduced . The minimum RMS power capa-
bility of the speakers or speaker groups must be:
4 Ω speaker: 250 W
8 Ω speaker: 160 W
Connect the speakers or speaker groups to the
output jacks (14):
CH 1+ = positive pole
of mid-high range speaker, left
CH 1− = negative pole
of mid-high range speaker, left
CH 2+ = positive pole
of mid-high range speaker, right
CH 2− = negative pole

5.7 Tri-Mode
In the Tri-Mode (fig . 9), it is possible to operate
a subwoofer in bridge operation and two mid-
high range speakers . Set the switches (8) on the
rear panel of the unit as follows:

5.7.1 Inputs
Connect the output of the line source (e . g .
preamplifier, mixer, etc .) to the inputs of the
amplifier:
Connect the left channel to the input jack CH 1
and the right channel to the input jack CH 2 .
The XLR jacks (12) or the 6 .3 mm jacks (13) can
be used as inputs . The inputs CH 3 and CH 4 are
not connected .

5.7.2 Outputs
The amplifier is able to operate two mid-high

range speakers or two mid-high range speaker
groups and, in bridge operation, a subwoofer
or a subwoofer group .
For the mid-high range speakers, the highest
output power is obtained when connecting 4 Ω
speakers and speaker groups with a total imped-
ance of 4 Ω each . However, it is also possible to
connect 8 Ω speakers or speaker groups with a
total impedance of 8 Ω . In this case, the output
power will be slightly reduced . The minimum
RMS power capability of the speakers or speaker
groups must be:
4 Ω speaker: 250 W
8 Ω speaker: 160 W
Due to bridge operation for the subwoofer or
the subwoofer group, the minimum impedance
of the speaker or the minimum total impedance
of the speaker group must be 8 Ω and the mini-
mum power capability 500 W RMS .
Connect the speakers or speaker groups to the
output jacks (14):
CH 1+ = positive pole
of mid-high range speaker, left
CH 1− = negative pole
of mid-high range speaker, left
CH 2+ = positive pole
of mid-high range speaker, right
CH 2− = negative pole
of mid-high range speaker, right
CH 3+ = positive pole of subwoofer
CH 4+ = negative pole of subwoofer

5.8 Power supply

After all other connections have been made,
connect the mains plug of the connection cable
(11) to a mains socket (230 V/ 50 Hz) .

6 Operation
6.1 Limiter
The four power amplifiers of the amplifier are
provided with a limiter each to ensure that,
when the level controls (6) are advanced, the
volume will not further increase after it has
reached the maximum undistorted level . This will
prevent distortions at high volume and protect
the speakers connected .
The limiter can be switched on or off sep-
arately for each power amplifier . With the am-
plifier switched off, set the DIP switches PEAK
LIMITER (10) correspondingly .

6.2 Switching on and off

To prevent loud switching noise, always switch
on all other units of the audio system before
switching on the amplifier . After operation,
switch off the amplifier first .
1) Prior to switching on, set the controls CH 1 to
CH 4 (6) to "0" for the time being .
2) Switch on the amplifier with the POWER
switch (7) . After switching on, the yellow
LEDs POWER (5) will light up .
Attention!
After operation, set all level controls (6) to "0"
first and wait for approximately 3 minutes be-
fore switching on to allow the internal amplifier
to cool down the power amplifiers . Otherwise,
the unit may be damaged .

6.3 Adjusting the volume

According to the operating mode selected, the
volume of the speakers connected is adjusted
with the level controls CH 1 to CH 4 (6):

Caution!
Never adjust the amplifier to a very high vol-
ume . Permanent high volumes may damage
your hear ing! Your ear will get accustomed to
high vol umes which do not seem to be that
high after some time . Therefore, do not further
increase a high vol ume after getting used to it .
Adjust the desired volume with the correspond-
ing level controls . If the output power exceeds
