2) To connect audio units with line level output
(e . g . MP3 / CD player, radio), use the following
jacks:
– RCA jacks LINE 3 and LINE 4
– 6 .3 mm jacks MIC 2 / LINE 1 and MIC 3 / LINE 2
Mono units can be directly connected; for
stereo units, use a stereo/mono adapter
(e . g . SMC-1) . When connecting, set the DIP
switches No . 1 and No . 2 to the position ON
(also see table) .
3) For important (emergency) announce-
ments, use the input TEL INPUT . It is possible
to connect, for example, a telephone system
with line level output to this input .
Note: As soon as a signal is available at this input, all
other signals will be muted, even when the control
TEL is in the position "0" . Announcements via the
input MIC 1, however, can be heard and will mute
the signal of the input TEL INPUT if DIP switch No . 4
is in the position OFF .
4) To insert an audio unit for signal processing
(e . g . an equalizer or an automatic volume con-
trol), use the RCA jacks AMP IN and OUTPUT .
To do so, remove the jumper from the jacks,
connect the input of the audio unit to the
jack OUTPUT and connect the output to the
jack AMP IN .
Note: The signal in the amplifier will be interrupted
if only one of the two jacks is connected or if the

unit inserted is not switched on, if it is defective or
not correctly connected . In this case, the speakers
will remain mute .
5) Connect an FM antenna to the jack FM AN-

TENNA . With good reception conditions, the
wire antenna provided can be used .
3.2 Outputs
1) Speakers: Either connect 100 V or 70 V
speakers to the terminals "100V" or "70V"
and "COM" (page 2, fig . 1) . The load by
the speakers must not exceed 120 W; other-
wise, the protective circuit will interrupt the
connection to the speaker terminals .
Or connect a speaker or a speaker group to
the terminals "4 Ω", "8 Ω" or "16 Ω" and
"COM" . The total impedance of the speak-
ers must not fall below the value indicated
at the terminal used . Figure 2 on page 2
shows various ways to observe the minimum
impedance . There are, however, also other
possibilities .
2) The output MOH OUTPUT (music on hold) is
able to provide, for example, music on hold
for a telephone system. The mixed signal is
also available at this output, however, with-
out the announcements of input MIC 1 . The
control MASTER will not have any effect on
the volume .

3.3 Power supply

For power supply, either connect the jack
"230 V~" to a mains socket (230 V/ 50 Hz) using
the mains cable provided or, for mobile applica-
tions (e . g . in a caravan), connect the terminals
"24 V⎓" to a 24 V DC voltage source (power
rating see "Specifications") . Always observe the
correct polarity of the positive and negative ter-
minals!
