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) 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 the power
rating of the amplifier (
☞
chapter 1 or “Spec-
ifications”); otherwise, 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) At the RCA jacks OUTPUT 1 and 2, the mixed
signal is available which is also reproduced
via the speakers. Use the control MASTER to
adjust the volume of the signal OUTPUT 1;
this control will not have any effect on the
volume of the signal OUTPUT 2. The jacks can
also be used, for example, for additional PA
amplifiers if more speakers are required than
the PA-8xxDMP can handle.
3) 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 applications (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 terminals!
