4 2 Microphone Connection And Basic Setting; 5 Units With Line Level / Audio Recorder; 6 Inserting The Equalizer Or Another Unit; 7 Additional Amplifier - Monacor PA-1120 Mode D'emploi

the storage M 6 of the PA-1120DMT can be
called up via the zone paging microphone
(position ON) or not (position OFF, factory
setting) . The storage M 6 can e . g . be used
for an alarm announcement which is only to
be activated via the terminals MESSAGE FIRST
PRIORITY (33) .
10) In the amplifier, set the jumper MS 2 to posi-
tion PRI . Thus, the volume of an announce-
ment from the insertion will not be attenuated
by a signal of the zone paging microphone .
6.4.2 Microphone connection and
basic setting
1) Connect the jack OUTPUT (62) of the micro-
phone to the jack INPUT of the connection
module . A short connection cable is supplied
with the microphone . The cable length be-
tween amplifier and microphone must be
1000 m as a maximum .
A 2 microphone may be connected via its
nd
jack OUTPUT to the jack LINK of the module or
to the jack LINK (61) of the 1
the connection of a 3 microphone, connect its
rd
jack OUTPUT to the jack LINK of the 2
phone . As a maximum, three microphones
may be connected . The cable length between
two microphones must not exceed 100 m .
2) When using several microphones of type
PA-1120RC, set the TALK switch (60) to po-
sition PRIORITY on the microphone or on the
microphones which are to take priority over
the others . On the other microphones, set the
switch to position SLAVE . Thus, an announce-
ment from a microphone without priority can
be interrupted by a microphone with priority .
3) To obtain 2 nd priority for the zone paging mi-
crophone or the zone paging microphones,
press the button on the connection module
(position PRIORITY) . If the button is not pressed
(position SLAVE), 4 priority is adjusted .
th
4) If the digital message insertion PA-1120DMT
is used, select with the switch DIGITAL
MESSAGE (59) if stored announcements can
be called up via the zone paging microphone
(switch position ON) or if they are locked
(position OFF) .
5) If the inputs on the amplifier do not suffice, a
line input signal can be fed via the jacks AUX
IN (63) [e . g . background music from a CD
player] . Adjust the output level for the micro-
phone signal and the signal from the jacks
AUX IN with the control AUDIO OUT (64) .
6.5 Units with line level /
audio recorder
Up to five units with line level (e . g . CD players,
cassette recorders) may be connected to the in-
puts CH 1 to CH 3 (39) as well as CH 4 and
CH 5 (38) . Exceptions: Do not use CH 1 when
operating the desk microphone PA-4000PTT or
PA-4300PTT and do not use CH 2 when oper-
ating the zone paging microphone PA-1120RC!
For background music, the inputs CH 4 and
CH 5 should be used because these have the
lowest priority .
1) When connecting the inputs CH 1 to CH 3,
turn the corresponding GAIN control (41)
fully to the left to position "−10" . Do not
press the corresponding button PHANTOM
POWER (40) .
When connecting a stereo unit to one
of the inputs CH 1 to CH 3, use a stereo
mono adapter (e . g . SMC-1 from MONACOR)
and an adapter cable (e . g . MCA-300 from
MONACOR), otherwise the signals of the ste-
reo centre cancel each other mutually .
2) If one of the inputs CH 1 to CH 3 is to take
priority over the other two inputs, set the cor-
responding DIP switch MIC PRIORITY (45) to
position ON . The inputs CH 1 to CH 3 always
take priority over the inputs CH 4 and CH 5
(also see chapter 7) .
3) An audio recorder may be connected to the
jacks REC (37) . The recording volume is inde-
pendent of the MASTER control (21) and the
zone attenuators (5) .
6.6 Inserting the equalizer or
another unit
For external sound effects, e . g . an equalizer may
be inserted via the jacks AMP IN (35) and PRE
OUT (36): Connect the input of the unit to the
jack PRE OUT and the output to the jack AMP IN .
Note: A signal interruption occurs in the amplifier if
only jack AMP IN is connected or if the inserted unit is
not switched on, if it is defective, or if it is not correctly

nd

6.7 Additional amplifier

If more speakers are required than admissible for
the amplifier, another amplifier is necessary . Con-
nect the input of the additional amplifier to the
jack PRE OUT (36) or REC (37) . The signal for the
additional amplifier is not affected by the control
MASTER (21) and by the zone volume switches (5) .

6.8 Telephone bell or night bell

If required, a telephone bell or night bell may
sound via the PA system (e . g . during a nightly
inspection round) .
1) Feed the signal for the bell (e . g . 8 V/ 50 Hz) to
the terminals NIGHT RINGER (29) .
2) Press the button TEL (14) .
3) Trigger the bell, and adjust the volume of the
ringing tone generated by the amplifier with
the control RINGER (16) .
4) Switch on or off the ringing function with the
button TEL according to your requirements .
Note: The bell takes the lowest priority .

6.9 Emergency priority relays

If PA volume adjusting controls with emergency
priority relays (e . g . series ATT-3 . .PEU or ATT-5 . .
PEU from MONACOR) are inserted between the
amplifier and the speakers, important announce-
ments can also be heard with the volume "zero"
adjusted .
1) For this purpose, connect a desk microphone
PA-4000PTT or PA-4300PTT (see chapter 6 .3) .
2) Connect the emergency priority relays accord-
ing to fig . 6 to the screw terminals PRIORITY
RELAY OUTPUT (42) . The output allows a load
of 200 mA .
3) Set the switch PRIORITY (48, 53) on the
microphone to position ON (downwards) .
4) Upon actuation of the TALK button (51, 58),
the speakers are now switched to maximum
volume via the relays .

6.10 Switch for (automatic)
announcements in all zones
For remote control of the following functions,
connect a switch to the terminals MESSAGE FIRST
PRIORITY (33) .
1 . All PA zones are switched on and set to maxi-
mum volume [like button ALL CALL (6)] .
2 . When the digital message insertion PA-
1120DMT is used, the announcement of
storage M 6 is automatically called up . For
this purpose, set the jumper MS 2 to position
PRI prior to installing the insertion (see layout
diagram on page 48) . Thus, the announce-
ment of storage M 6 takes first priority .
Instead of the switch, an alarm contact may
be connected, e . g . for an automatic fire alarm
announcement .
3 . If the amplifier is to be switched on simulta-
neously via the switch or the alarm contact,
insert a diode of type 1N4004 between the
upper terminal MESSAGE FIRST PRIORITY and
the right terminal POWER REMOTE according
to fig . 7 .

6.11 Telephone switchboard

From a telephone switchboard, announcements
may be reproduced via the PA system .
1) Feed the telephone signal (line level) to the
terminals PAGING IN (32) .
2) During an announcement, adjust the volume
with the control PAGING (15) .
Note: Telephone announcements take 3rd priority .
6.12 Switching on / off by
remote control
A separate switch allows to switch the amplifier
on and off by remote control .
1) Connect the screw terminals POWER REMOTE
(31) via a two-pole cable to a single-pole
power switch .
2) For switching on / off by remote control, the
main switch POWER (24) must not be pressed .
6.13 Power supply and emergency
power supply
1) For continuous operation of the amplifier
after power failure, connect a 24 V emer-
gency power supply unit (e . g . PA-24ESP from
MONACOR) to the terminals 24 V⎓ (30) . For a
cable length of up to 7 m, a cable cross-section
of 4 mm 2 as a minimum is required .
2) Finally connect the supplied mains cable to
the mains jack (27) first and then to a mains
socket (230 V/ 50 Hz) .
Note: Even when the amplifier is switched off, it has
a low power consumption . Therefore, disconnect the
mains plug from the socket and, if necessary, disconnect
the emergency power supply unit if the amplifier will not
be in operation for a longer time .
