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
☞
chapter 6).
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.
