5 Connecting the Amplifier

The inputs and speakers may only be connected when
the unit is switched off!
5.1 Inputs
MIC 1 and MIC 2 (1) Connections for low impedance
microphones
PHONO (13) Connection for a turntable with
magnet system
AUX/CD (14) Connection for a unit with line
output, e. g. CD player, tape
deck or turntable with ceramic
system
A Y cable is required for stereo units with two outputs
so that both outputs are led to the corresponding com-
mon amplifier input.
If the turntable has a separate ground cable, connect it
to the GND screw (11).
5.2 Speakers
The speakers can be connected as shown in fig. 3 – 8.
Connect them to the terminals (10) accordingly. Pay
attention to the correct individual resp. total speaker
impedance as well as to the correct phase connection
of the speakers (positive and negative connections, as
shown in fig. 3 – 8). The positive connection of the
speaker cable is always specially marked.
Attention!
The total load of all speakers must not exceed
when using PA speakers with 100 V audio

transformer (fig. 8), as otherwise the amplifier will be
overloaded. This may result in amplifier damage.
5.3 Priority Switch
1) Finally, connect the amplifier to a power mains sup-
ply (230 V~/50 Hz).
2) If in case of a power failure of the 230 V mains the
amplifier should continue to operate, the power
failure back-up of the amplifier can be connected to
a 12 V rechargeable battery via the terminals
