5 Connecting the Amplifier

The inputs and speakers may only be connected when
the unit is switched off!
5.1 Inputs
AUX (12) Connection for a unit with line
output, e. g. CD player, tape
deck or turntable with ceramic
system
PHONO (13) Connection for a turntable with
magnet system
MIC 1 and MIC 2 (14) Connections for low impedance
microphones
If the turntable has a separate ground cable, connect it
to the GND screw (10).
5.2 Speakers
The speakers can be connected as shown in fig. 3 – 8.
Connect them to the terminals (9) 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
35 W when using PA speakers with 100 V audio
RMS
transformer (fig. 8), as otherwise the amplifier will be
overloaded. This may result in amplifier damage.
5.3 Priority Switch
A priority switch (make contact) can be connected to
the PRIORITY connection terminals (8). Channels
MIC 2 and PHONO/AUX can be faded out when this
priority switch is kept depressed so that only an -
nounce ments via MIC 1 can be heard. After releasing
the priority switch, channels MIC 2 and PHONO/AUX
are softly faded in again.

5.4 Power Supply

Finally, connect the amplifier to a power mains supply
(230 V~/50 Hz).
6 Operation
1) Turn the MASTER VOLUME control (4) to zero
before switching on. Switch on the amplifier via the
POWER switch (5).
2) Set the PHONO/AUX selector (11) to the AUX posi-
tion. The selector must be set to PHONO position
only if a turntable with magnet system is used.

3) Slightly turn up the MASTER VOLUME control (4).
Adjust the desired volume in relation to each other
via MIC 1, MIC 2 (1), and PHONO/AUX (2). Set all
controls which are not connected to a source to
zero.
4) Adjust the tone with the controls (3) 150 Hz (bass),
1 kHz (midrange) and 6 kHz (treble) and the total
volume with the MASTER VOLUME control (4).
5) If desired, fade the microphones in and out with the
MIC 1 and MIC 2 (1) controls resp. the music source
with the PHONO/AUX control (2).
6) If a priority switch for microphone MIC 1 is con nect-
ed, keep it pressed during announcements. Chan-
nels MIC 2 and PHONO/AUX will be faded out and
only the announcement will be heard. After releas-
ing the priority switch, channels MIC 2 and
PHONO/AUX will be softly faded in again.
