space above and below the amplifier to en-
sure sufficient ventilation . If the heat dissipa-
tion is insufficient, install a ventilation unit
into the rack; otherwise heat will accumulate
in the rack and may not only damage the
amplifier but also other units in the rack .
5 Connections
(Example for connection ☞
Prior to making or changing any connections,
switch off the amplifier and the units used .
1) Connect the audio sources to the inputs:
– microphones to the 6 .3 mm jacks VOICE 1
(24) and VOICE 2 (23)
– stereo units with line output level (e . g . CD
player or DVD player, tape deck, tuner)
to the RCA jacks MUSIC 1 (22) and
MUSIC 2 (21): white jack = left channel,
red jack R = right channel
Instead of the input MUSIC 2 on the rear
panel, the corresponding input (12) on
the front panel can also be used .
2) Connect the speaker systems to the ter-
minals SPEAKER (25) [RIGHT = right chan-
nel, LEFT = left channel] . The impedance
of the speakers must not fall below 4 Ω;
otherwise you may damage the amplifier .
When you connect the speakers, always
connect the marked core of the speaker
cable to the red terminal to prevent reverse
polarity and signal cancellation .
3) It is possible to connect two additional
power amplifiers or other units with
line input level (e . g . mixer, effect unit)
each to the RCA jacks of the outputs AMP
OUTPUT 1 (18) and AMP OUTPUT 2 (17) .
4) It is possible to connect a recorder to the
RCA jacks REC (20) and stereo head-
phones (minimum impedance 32 Ω) to
monitor the output signal to the 6 .3 mm
jack (13) . Adjustments of the controls
LEVEL (16 and 19) have no effect on the
output signal at the recording output and
the headphone output .
When you connect headphones, the
outputs AMP OUTPUT (17 and 18) and the
speakers outputs (25) are muted . The mut-
ing feature is also activated via a switch or
momentary pushbutton connected to
the screw terminals MUTE (15) . To facilitate
handling, disconnect the terminals from
the unit and reconnect them after screwing
on the cable for the switch .
5) Finally connect the plug of the mains cable
(27) to a socket (230 V/ 50 Hz) .

6 Operation
CAUTION Never adjust the audio sys-
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
page 2)
volume after getting used to it .
1) As a basic setting, prior to initial operation,
set the controls LEVEL (16 and 19) to the
left stop using a small screwdriver .
2) To prevent loud switching noise, always
switch on all other units of the audio sys-
tem before switching on the power ampli-
fier; after operation, switch off the power
amplifier first .
Switch on the amplifier with the
POWER switch (4); the POWER LED (3)
lights up .
3) Use the corresponding volume controls
to adjust the desired volume ratio of the
audio sources:
– control VOICE 1 (5) for the microphone
at the input VOICE 1 (24)
– control VOICE 2 (7) for the microphone
at the input VOICE 2 (23)
– control MUSIC 1 (9) for the unit at the
input MUSIC 1 (22)
– control MUSIC 2 (11) for the unit at the
input MUSIC (INPUT) 2 (12 or 21)
Always set the controls of channels that are
not used to the left stop to "0" .
4) The channels VOICE 1 and VOICE 2 are
equipped with a 3-way equalizer (6 and 8)
each; the channels MUSIC 1 and MUSIC 2
have a joint 2-way equalizer (10) . To boost
or attenuate the frequency ranges (LOW,
MID, HIGH) by up to 12 dB, turn the cor-
responding controls .
5) The control LEVEL 1 (19) is used to boost
the level of the master signal fed to the
internal power amplifier and available at
the output AMP OUTPUT 1 (18) . If the
reproduction via the speakers connected
is too low even though a high volume has
been adjusted and /or if the signal level for
the unit at the output AMP OUTPUT 1 is
too low, turn up the control as required .
The control LEVEL 2 (16) is used to
boost the level of the master signal avail-
able at the output AMP OUTPUT 2 (17) . If
the level is too low for the unit connected
to this output, turn up the control as
required .

6) In case of overload of the amplifier, the
LEDs CLIP (2) light up for the right channel
and the left channel each . In this case, turn
back the control LEVEL 1 (19) as required
and /or turn back any volume controls of
the input channels that have been set too
high .
7) Turn up the volume control (14) for the
headphone output
headphones reproduce the output sig-
nal unaffected by the controls LEVEL (16
