Operating Elements And Connections; Safety Notes - Monacor PA-5240 Bedienungsanleitung

PA Mixing Amplifier
for 5 Zones
Please read these operating instructions care­
fully prior to operation and keep them for
later reference . All operating elements and
connections described can be found on the
fold­out page 3 .
Connection of the speakers (chapter 5)
requires adequate technical knowledge in
100 V PA technology and is to be made by
experts only . Operation of the amplifier is easy
(chapter 6), even for adults without any ex­
pert knowledge . However, in case of any que­
ries, please contact your installer or retailer .
1 Operating Elements
and Connections

1 Cover of the insertion compartment;
a MONACOR insertion can be installed
here, e . g tuner, MP3 / CD player, digital
message insertion
2 Chime key
3 Switch for selecting the inputs AUX 5 – 7

"Treble" (±10 dB / 10 kHz)
5 Additional tone controls for a unit in­
stalled in the compartment (1)
6 Zone attenuators for separate volume
control of the individual speaker zones
7 Microphone input MIC (6 .3 mm jack, bal .)
for input 1, connected in parallel to the
jack INPUT­1 (21)
8 Level controls of inputs 1 – 4 and AUX
9 MASTER control for the master volume
10 VU­meter for the power amplifier [inde­
pendent of the zone attenuators (6)];
in case of overload, the red LED "clip"
will light up
11 LED "stand by", will light up when the
amplifier has been switched off
12 LED "power", will light up when the unit
is switched on
13 LED "prot"; will light up when the ampli­
fier has been muted due to overheating
14 POWER switch
1.2 Rear panel
15 Protective cover for the screw terminals
Caution! Never operate the amplifier
without the cover .
16 Speaker terminals for the 100 V speakers
Attention! Each of the five zone out­
puts allows a maximum load of 100 W
RMS by the speakers; however, the total
admissible load must never be exceeded:
PA­5240 240 W RMS
PA­5480 480 W RMS
17 Cover; when installing an insertion, fur­
ther connections can be fitted here, if
required
8
18 6 .3 mm jacks AMP IN and PRE OUT for
inserting a unit, e . g . equalizer;
it is also possible to connect a second
PA amplifier to the jack PRE OUT if the
output power is not sufficient for oper­
ating further speakers
19 Inputs AUX 5 – 7 for units with line level
(e . g . MP3 / CD player, cassette recorder,
etc .), to be selected with the sliding switch
(3); the two stereo channels L and R re­
spectively will be internally mixed to a
mono signal
20 Input jack for channel 2 (combined XLR /
6 .3 mm jack) for connecting a microphone
[button "Mic / Line" (35) not pressed] or
a unit with line level [button "Mic / Line"
pressed]; connected in parallel to the ter­
minal strip (34) below it
21 Input jack for channel 1 (combined XLR /
6 .3 mm jack) for connecting a microphone;
connected in parallel to the jack MIC (7)
22 Ground connection for the two speaker
connections "8 Ω" (23) and "100 V" (25)
next to it
23 Direct output for an 8 Ω speaker or an
8 Ω speaker group;
the zone attenuators (6) will not affect
this output
Attention! Only use this output when
the 100 V outputs (16 and 25) are not
used . Otherwise, this will result in over­
load of the amplifier .
24 Mains jack for connection to a mains
socket (230 V/ 50 Hz) via the supplied
mains cable
25 Direct output for 100 V speakers;
the zone attenuators (6) will not affect
this output
Attention! The total load of all speakers
connected must not exceed 240 W RMS
(PA­5240) or 480 W RMS (PA­5480) .
26 Terminal strip* AC POWER REMOTE for
an external switch for remote activation
and deactivation
Note: For remote activation, the unit must not
be switched on with the POWER switch (14) .
27 Fuse for the emergency power supply;
always replace a blown fuse by one of
the same type
28 Screw terminals for an emergency power
supply: 24 V (⎓)
29 GROUND/ LIFT switch; in case of hum
problems, for separating the signal
ground from the housing ground (LIFT)
or for connecting them (GROUND)
30 Screw terminals
"Remote Siren" for remote activation of
the siren via a switch
"Remote Chime" for remote activation of
the chime via a momentary pushbutton
switch
"INPUTS Chime On /Off" with short circuit
bridge
When the bridge is removed, remote acti­
vation of the chime via the terminal strips
(34) of inputs 2 – 4 will be impossible .
31 Control "Mute Level" for adjusting the
volume attenuation in case of announce­
ments or activation of the chime or siren
32 Control "Siren Level" for adjusting the
siren volume
33 Control "Chime Level" for adjusting the
chime volume
34 Terminal strips* for inputs 2 – 4; for chan­
nel 2, this input is connected in parallel
to the jack (20) above;
The contacts are used respectively
for remote activation of the chime and
for automatic volume attenuation of the
AUX channel .
35 Selector switch of inputs 2 – 4: micro­
phone level (button not pressed) or line
level (button pressed)
36 Switch "P .H . +18 V" of inputs 2 – 4 for con­
necting the 18 V phantom power; required
when connecting phantom­ powered con­
denser or electret microphones
Attention! With the phantom power
connected, never connect any unbalanced
microphones to the corresponding inputs;
these microphones may be damaged .
37 Switch "P .H . +18 V" for input 1 for con­
necting the 18 V phantom power

2 Safety Notes

The unit corresponds to all relevant directives
of the EU and is therefore marked with
WARNING The unit uses dangerous
mains voltage . Leave servicing
to skilled personnel only and
do not insert anything into the
air vents! Inexpert handling or modification
of the unit may result in electric shock .
During operation, there is a hazard of
contact with a voltage up to 100 V at the
speaker terminals (16, 25) . Never oper­
ate the amplifier without the protective
cover (15) .
Always switch off the PA system before
