*Important:
When phantom power has been acti-
vated, do not connect any microphone or audio unit
with unbalanced output signal to the input CH1; the
microphone/audio unit may be damaged .
Note:
When announcements are being made via
the channels CH 2 and CH 3, the signals of the music
module and of the inputs CH 4 and CH 5 will be
slightly attenuated .
2) To connect
audio sources
with line level out-
put (e . g . CD player, mixer), use the following
jacks:
– RCA jacks CH 4 and CH 5
– 6 .3 mm jacks CH 2 and CH 3
Note:
The inputs CH4 and CH5 are provided with
a pair of jacks for the connection of audio stereo
sources . The amplifier will create a mono signal from
the stereo signal . To connect stereo audio sources to
the inputs CH 2 and CH 3, use a stereo/mono adapter
(e . g . SMC-1) .
When connecting the audio sources to the
jacks CH 2 and CH 3, set the DIP switches 1
and 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:
A signal at the input TEL INPUT will mute all
other channels . When DIP switch 4 is in the position
OFF, however, announcements made via the input
CH 1 will have highest priority and will also mute the
channel TEL INPUT .
4) Connect a
DAB / FM antenna
to the jack
ANTENNA . With good reception conditions,
the wire antenna provided can be used .
5) If it is necessary
to mute the speaker out-
puts
, connect the two MUTE terminals, e . g .
via a switch .
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 rat-
ing of the amplifier (chapter 5); 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 speakers
must not fall below the value indicated at the
terminal used . Figure 2 on page 2 shows
various ways to observe the minimum imped-
ance . There are, however, also other possi-
bilities .
2) At the RCA jacks REC OUT 1 and 2, the mixed
signal is available . The control MASTER will not
have any effect on the volume of this signal .
The jacks can also be used, for example, for
a
recorder
or
additional PA amplifiers
if
more speakers are required than PA-803DAP
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 . The control MASTER
will not have any effect on the volume .
