3 Applications and
Accessories
The amplifiers PA­5240 and PA­5480 have
been specially designed for use in 100 V PA
systems . 100 V outputs for up to five speaker
zones are available . The volume of these
zones can be individually adjusted . To the
five input channels which can be mixed with
one another, microphones (channels 1 – 4) or
units with line level (channels 2 – 5) can be
connected . One of the following MONACOR
insertions can be installed into the insertion
compartment (1):
digital message storage
PA­1120DMT
with timer
PA­1140RCD radio / CD player
PA­1200C timer
PA­1200RDS AM / FM radio
The MONACOR PA PTT desk microphone
PA­5000PTT has been specially designed as
a separate accessory for these amplifiers and
can be connected to the terminal strips (34)
of channels 2 – 4 .

4 Setting up the Amplifier

The amplifier has been designed for instal­
lation into a rack (482 mm / 19"), however, it
can also be used as a table top unit . In any
case, air must be allowed to pass through all
air vents to ensure sufficient cooling of the
power amplifier .
4.1 Installation into a Rack
For installation into a rack, 3 rack spaces
(133 mm) are required . To prevent top­heav­
iness of the rack, the amplifier must be in­
serted into the lower part of the rack . The
front panel alone will not be able to secure
the unit; side rails or a base plate must be
additionally provided .
The hot air blown out at the side of the
amplifier must be dissipated from the rack;
otherwise, heat will accumulate in the rack
which may not only damage the amplifier but
also other units in the rack . In case of insuf­
ficient heat dissipation, install a ventilation
unit into the rack .

5 Connecting the Amplifier

All connections should only be made by quali­
fied skilled personnel . For this purpose, always
switch off the amplifier!
Numerous connections, e . g . those for the
speakers, are underneath the protective cover
(15) . For connection, unscrew the cover .
WARNING Do not operate the ampli­
fier without the protective
cover (15) . During operation,
there is a hazard of contact
with a voltage up to 100 V at the speaker
terminals (16, 25) . After connecting, screw
on the cover again so that the terminals are
protected against any accidental contact .
5.1 Speakers
1) Either connect 100 V speakers for the five
speaker zones to the terminals ATT ZONE
OUTPUTS (16)
Attention! In each speaker zone, the
maximum load by the 100 V speakers
may be 100 W RMS; however, the total
admissible load of all speakers must not
be exceeded:
240 W RMS (PA­5240) or
480 W RMS (PA­5480)
2) or a speaker group of a total impedance
of at least 8 Ω to the terminals COM (22)
and 8 Ω (23) . The zone attenuators (6) will
not affect this output .
3) Always observe the correct polarity when
connecting . For the 8 Ω connection, the
terminal COM is the negative pole and the
terminal 8 Ω the positive pole . The positive
connection of the speaker cables is always
specially marked .
4) Additional 100 V speakers, the volume of
which is not to be attenuated by the zone
attenuators (6) can be connected to the
terminals COM (22) and 100 V (25) . How­
ever, the total load of these speakers and
the speakers at the terminals ATT ZONE
OUTPUTS must not be exceeded (see note
"Attention" above) .
5.2 Microphones
Four microphones can be connected, one
microphone each to the channels 1 – 4:
1 . In channel 1 to the jack MIC (7) on the front
panel or to the combined XLR / 6 .3 mm jack
INPUT­1 (21)
A signal in channel 1 will take priority
over all other signals, i . e . the volume of
the other signals will be automatically at­
tenuated if you speak into the microphone
of channel 1 .
2 . In channel 2 to the combined XLR / 6 .3 mm
jack INPUT­2 (20) or to the terminal strip
(34) below it*
3 . In channel 3 to the terminal strip IN­
PUT­3 (34)*
4 . In channel 4 to the terminal strip IN­
PUT­4 (34)*
* Note: When the talk button of the microphone
PA­5000PTT is pressed, the volume of the AUX
channel will be automatically attenuated .
To facilitate handling, it is possible to remove
the terminal strips (34) from their plug­in con­
nections on the unit and to reinsert them after
connection .
1) Connect the microphones to the corre­
sponding terminals .
Connect the microphones PA­5000PTT
to the terminal strips (34) so that it will be
possible to activate the chime from these
microphones and to attenuate the volume
of the AUX channel .
2) In channels 2 – 4, the button "Mic / Line"
(35) must not be pressed when connecting
a microphone so that the input is switched
to microphone sensitivity .
3) When using a phantom­powered micro­
phone, press the corresponding button
"P .H . +18V" (36, 37) . The microphone
will then be supplied with 18 V by the
amplifier .
Attention! With the phantom power
connected, unbal anced microphones
must not be connected to the corre­
sponding inputs; these microphones may
be damaged .

5.3 Units with line output

Six units with line output (e . g . MP3 / CD
player, tuner, tape deck) can be connected,
one unit each to channels 2 – 4 and three units
to the AUX channel .
1) Connect the units to the corresponding
terminals:
– combined XLR / 6 .3 mm jack INPUT­2 (20)
– terminal strips INPUT­2 to INPUT­4 (34)
– RCA jacks AUX INPUTS (19)
When connecting a stereo unit to the com­
bined XLR / 6 .3 mm jack (20), use a stereo
mono adapter (e . g . SMC­1 from MONA­
COR) and an adapter cable (e . g . MCA­300
from MONACOR); otherwise, the signals
of the stereo centre will cancel out each .
2) In channels 2 – 4, press the corresponding
button "Mic / Line" (35) when connecting
a unit with line level so that the input is set
to line level . To ensure that the phantom
power is deactivated, the corresponding
button "P .H . +18V" (36) must not be
pressed .
3) For the AUX channel, use the selector
switch "5 6 7" (3) to select the unit to
be heard .
5.4 Inserting an equalizer or another unit
For external effects on the sound, e . g . an
equalizer can be inserted via the jacks IN­
SERTS (18) .
1) Connect the input of the unit to the jack
PRE OUT .
2) Connect the output of the unit to the jack
AMP IN .
Note: The signal in the amplifier will be interrupted
if merely the jack AMP IN has been connected, if
the inserted unit has not been switched on, or if it
is defective or not correctly connected . In this case,
the speakers connected will remain mute .
