4 Mounting and Connection

As suggested in the drawing, the amplifier may
be mounted via its mounting brackets (e . g . to the
rear side of a speaker system next to the terminals) .
To ensure sufficient cooling, air must always
be able to flow freely through the cooling fins on
the rear of the unit and through the air vents of
the housing .
4.1 Connecting the signal source
For connection of a signal source with line level
(e . g . CD player, mixer output, line output of a com-
puter) there are the following possibilities:
1) For balanced signals the XLR jack (3) is suitable
(configuration of the contacts
2) For unbalanced signals the RCA jacks (2) are
suitable . When using both RCA jacks at the same
time, the input signals are mixed . Therefore, a
mono signal is created when connecting a stereo
signal source .
4.2 Connecting the speakers
Connect a speaker with an impedance from 4 Ω to
8 Ω to the cables led through the lower side of the
amplifier (red = +, black = −) . When connecting
several speakers, make sure that the total imped-
ance does not fall below 4 Ω .
4.3 Power supply
Connect the supplied mains cable to the mains jack
(4) and the plug to a socket (230 V/ 50 Hz) .

5 Operation

CAUTION Never adjust the amplifier to a
very high volume . Permanent high
volumes may damage your hear-
ing! Your ear will get accustomed
to high volumes which do not seem to be that
high any more 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
amplifier after the units connected and switch it off first
after use .
1) Set the control LEVEL (1) to minimum (left stop)
first and switch on the amplifier with the POWER
switch (6) . The switch lights up .
2) Adjust the desired volume with the control
LEVEL . Only turn up the control to such an extent
that the sound will not be distorted .
3) After use, switch off the amplifier with the
POWER switch .
