power supply unit
24 Common ground connection COM for all
speakers
25 Screw connections for the 4 Ω and 8 Ω speakers
26 Screw connections Z 1 – Z4 for speakers with
70 V or 100 V audio transformer
27 Selector switch 70 V / 100 V for the speaker
outputs Z 1 – Z4 (26)
position 70 V for speakers with 70 V audio
transformer
position 100 V for speakers with 100 V audio
transformer
28 6 .3 mm jack PRE OUT / AMP IN, can be used
as an output or input:
output for the complete mixing signal, in-
dependent of control MASTER (13), e . g . to
connect another amplifier
input for a line signal which is to be fed di-
rectly to the power amplifier; only the volume
of the signal can be influenced with the con-
trol MASTER (13)

channel CH 5
30 RCA input jacks for the line / phono channel
CH 5
31 Line input for channel CH 4 (e . g . for tuner,
CD player, tape recorder, etc .)
32 Selector switch for channel CH 4
LINE The RCA jacks (31) for a device with line
output are selected .
MIC The XLR jack (33) for a microphone is
se lected .
33 Microphone input (bal .) for channel CH 4
34 Line / microphone selector switch for channels
CH 2 and CH 3
35 DIP switches for switching on the 15 V supply
voltage for phantom-powered microphones;
each for the inputs CH 2 and CH 3
Caution! Only actuate the switches with the am-
plifier switched off (switching noise) . With the
phantom voltage switched on, no microphone
with unbalanced output must be connected to the
corresponding input as this microphone may be
damaged .
36 Control MUTE to adjust to which extent the
volume of the other channels is to be attenu-
ated in case of an announcement via micro-
phone channel CH 1
control at the left stop:
no volume attenuation
control at the right stop:
maximum volume attenuation

2 Safety Notes

The device corresponds to all relevant directives of
the EU and is therefore marked with
The device corresponds to the relevant UK legisla-
tion and is therefore marked with UKCA .
WARNING The device uses dangerous mains
voltage . Leave servicing to skilled
personnel only and do not insert
anything into the air vents . Risk of
electric shock!
•
The device is suitable for indoor use only . Pro-
tect it against dripping water and splash water,
high air humidity and heat (admissible ambient
temperature range 0 – 40 °C) .
•
Do not place any vessels filled with liquid, e . g .
drinking glasses, on the device .
•
The heat generated within the device must be
carried off by air circulation . Therefore, do not
cover the air vents of the housing with any
objects .
•
Do not operate the device and disconnect it
immediately from the power supply
1 . if there is visible damage to the device or to
the power supply cable,
2 . if a defect might have occurred after the
device was dropped or suffered a similar
accident,
3 . if malfunctions occur .
In any case the device must be repaired by
skilled personnel .
•
Never pull the mains cable to disconnect the

the plug .
•
For cleaning only use a dry, soft cloth, by no
means chemicals or water .
•
No guarantee claims for the device and no li-
ability for any resulting personal damage or
material damage will be accepted if the device

If the device is to be put out of opera-
tion definitively, dispose of the device
in accordance with local regulations .

3 Applications and Accessories

The amplifier PA-1200 is designed to set up a
PA system for general PA applications . The differ-
ent screw terminals (25 and 26) allow to connect
different speaker combinations (see figs . 3 to 9) .
Speakers with 70 V or 100 V transformer can be
split to four PA zones which can separately be
switched on and off .
The five input channels to be mixed with each
other allow to connect microphones (channels
CH 1 to CH 4), devices with line level (channels
CH 2 to CH 5) or a turntable (channel CH 5) .
One of the following insertion modules from
MONACOR can be placed in the extension com-
partment (1):
PA-1120DMT Message storage with timer
PA-1140RCD AM / FM tuner and CD / USB player
internetradio, DAB / FM tuner and
PA-1200IRD
USB player
PA-1200RDSU AM / FM tuner and USB player
For this purpose screw off the cover plate (1) so
that the desired module can be placed into the
insertion compartment .

4 Setting-up
The device is provided for insertion into a rack
(482 mm / 19"), but it can also be used as a table
top device . In each case air must be allowed to
move freely through all vents so that there is no
heat accumulation within the device .
For inserting the amplifier into a rack, the
mount ing frame PA-1200RM from MONACOR is
required . There should be enough space above
and below the amplifier so that a sufficient ven-
tilation is ensured . To prevent the rack from be-
coming top-heavy, the amplifier must be placed
in the lower area of the rack .
