Overview
a MONACOR insertion can be installed here,
e . g . tuner, CD player, digital message inser-
tion
compartmeπnt (1)
partment (1)
individual PA zones Z 1 to Z 5
ment of the individual zones
activating all zones at the same time and
for increasing the volume to the maximum
[independent of the buttons (4) and the zone
attenuators (5)]; the maximum volume is only
limited by the MASTER control (21)
pendent of the zone attenuators (5)];
in case of overload, the red LED CLIP will light
up
Control CH 1 will also adjust the level for a
microphone connected to the jack (43) or
(44); control CH 2 will adjust the level for
zone paging microphones of type PA-1120RC
(connected via a separate module):
the priority of these inputs is adjusted with
the DIP switches (45)
to CH 3 (39)
CH 5 (38)
and CH 5
(for switching over between 2-tone chime and
4-tone chime see chapter 5)
e . g . be possible to hear a telephone bell or
night bell via all speakers [connection via the
terminals NIGHT RINGER (29)]; the bell will
take the lowest priority
via the terminals PAGING IN (32); this signal
will take 3 priority
rd
bell (also see items 14 and 29)
take 4 th priority
will light up when the temperature of the
heat sink has reached 100 °C . In this case, all
speaker outputs will be muted . In addition,
the red LED PROT (22) will light up .
circuit is activated:
1 . for approx . 1 second after switching on
(switch-on delay)
2 . for approx . 1 second after switching off
3 . if the amplifier is overloaded
4 . if the amplifier is overheated
23 POWER LEDs:
DC will light up when the amplifier uses a
24 V emergency supply voltage in case
of mains failure
AC will light up when the amplifier uses the
mains voltage
24 POWER switch
25 STAND BY LED;
will light up when the amplifier is switched off
1.2 Rear panel of amplifier
26 Speaker terminals for 100 V speakers
Attention! Each of the five zone outputs
allows a maximum load of 100 W RMS by
the speakers; however, the total load of
all zones must never exceed the following
value:
PA-1120 120 W RMS
PA-1240 240 W RMS
27 Jack for the mains cable supplied for connec-
tion to 230 V/ 50 Hz
28 4 Ω speaker output for a speaker group with
a total minimum impedance of 4 Ω
Attention! Only use this output if the 100 V
outputs (26) are not used, otherwise you will
risk overload of the amplifier .
29 Input for the bell voltage (e . g . 8 V/ 50 Hz) of a
telephone bell or night bell; the bell voltage
will trigger an audio signal which can be heard
via the speakers (also see items 14 and 16)
30 Screw terminals for an emergency power
supply (⎓ 24 V)
31 Screw terminals for an external switch for
activation / deactivation by remote control
[in this case, the switch POWER (24) must
not be pressed]
32 Input (bal ., 250 mV) for a telephone signal to
be heard via the PA system (also see item 15)
33 Connection for a separate switch;
priority
nd
if a digital message insertion PA-1120DMT
is installed, this connection allows to call up
a stored alarm announcement . At the same
time, all PA zones will be activated and set
to maximum volume [like the button ALL
CALL (6)]
34 Cover plate; will be replaced by a connec-
tion plate if the insertion PA-1120DMT,
PA-1140RCD or PA-1200RDSU is installed
35 Input AMP IN; in connection with the output
PRE OUT (36) for inserting e . g . an equalizer .
If this jack is connected, only the signal fed in
here will be reproduced . The power amplifier
will be disconnected from the preamplifier .
36 Output PRE OUT; for connection of an addi-
tional amplifier (chapter 6 .7) or in connection
with the input AMP IN (35) for inserting e . g .
an equalizer;
the output volume is independent of the
MASTER control (21)
37 Output REC for connecting a recorder; the
output volume is independent of the MASTER
control (21)
38 Inputs CH 4 and CH 5 for units with line level
(e . g . CD player, cassette recorder, etc .); the
two stereo channels L and R will be mixed
internally to a mono signal
39 Balanced inputs CH 1 to CH 3 via XLR / 6 .3 mm
jacks (combined jacks);
the input sensitivity can be adjusted between
microphone level and line level (2 .5 - 250 mV)
with the controls GAIN (41)
