Safety Notes; Applications And Accessories - Monacor PA-4000PTT Bedienungsanleitung

1.3 Desk microphone PA-4000PTT
(accessory available separately)
35 Microphone cartridge with windscreen
36 LED indicator, lights up with the talk button
(37) pressed
37 TALK button; for an announcement, keep
the button pressed and wait for the chime,
if necessary
38 Switch for priority circuit and preliminary
chime
PRIORITY – for use at the PA-40120, leave
this switch in the upper position as the prior-
ity of this microphone is defined in the ampli-
fier (for a better intelligibility of an announce-
ment, the other input signals are muted as
soon as talking starts or the chime sounds)
CHIME – in position ON, first a chime sounds
when the TALK button (37) is pressed
39 Jacks for connection to the amplifier; for
connection to the PA-40120, the RJ45 jack
(left) is required
1.4 Zone-paging microphone
PA-4000RC
(accessory available separately)
40 LED POWER / CPU ERROR lights up as soon
as the supply voltage is available; flashes in
case of a malfunction of the microprocessor
in the PA-4000RC
41 LED MIC FAULT/ LOW VOLTAGE lights up in
case of failure of the microphone, flashes if
the supply voltage is too low
42 LED SIGNAL lights up when a microphone
signal is available
43 Jack 24 V⎓ for additional voltage supply via
a power supply unit with a low-voltage plug
5 .5 / 2 .1 mm (outside / inside diameter) and
any polarity; the additional power supply unit
is required if the supply via the amplifier is
not sufficient (e . g . when more than 10 PA-
4000RC units are connected or a cable with
a length > 500 m is used)
44 Switch for the address and the line termi-
nation
I .D – with these 5 switches, different ad-
dresses have to be adjusted at all PA-4000RC
units prior to connection to the amplifier
☞
( chapter 5 .5 .3)
TERMINATION – at the final PA-4000RC con-
nected in a chain, set the switch to ON in
order to activate the terminating resistor
45 Switch
CHIME – in position ON, first a chime sounds
when pressing the TALK button (52)
PRIORITY – in position ON, the PA-4000RC
takes priority over all other microphones
without this function activated, and it is able
to interrupt their announcements
COMPRESSION – in position ON, the dynamic
power of the microphone signal is attenuated
to reduce distortions when talking at high
volume
46 RJ45 jack INPUT for connection of another
PA-4000RC
47 RJ45 jack LINK for connection to a jack
INPUT (33) of the connection module at the
amplifier or the jack INPUT (46) of another
PA-4000RC
48 Control AUDIO LEVEL to adjust the volume
of the announcement
49 Microphone cartridge with windscreen
50 Buttons for selection of the announcement
zones, each with the following status LEDs:
BUSY – lights up when the zone for an an-
nouncement has been selected; if an an-
nouncement is being made via a different
PA-4000RC, the LEDs for the respective zones
starts flashing
EMER . – lights up when an emergency situ-
ation has been signalled in the zone (via an
emergency microphone unit PA-4000FMP)
51 Button ALL CALL to simultaneously select
and deselect all zones for an announcement
52 TALK button; for an announcement keep the
button pressed and wait for the chime, if
necessary
The LED indicator above it lights up as long as
the button is pressed; the other input signals
of the amplifier (e . g . music) are muted for
a better intelligibility of the announcement

Safety Notes

The unit corresponds to all relevant directives of
the EU and is therefore marked with
WARNING The unit is supplied with haz-
ardous mains voltage . Leave ser-
vicing to skilled personnel only .
Do not insert anything through
the air vents . Inexpert handling of the unit may
cause an electric shock hazard .
•
The unit is suitable for indoor use only . Protect
it against dripping water and splash water,
high air humidity, and heat (admissible am-
bient temperature range 0 – 40 °C) .
•
Do not place any vessels filled with liquid, e . g .
drinking glasses, on the unit .
•
The heat being generated in the unit must be
carried off by air circulation . Therefore, the air
vents at the housing must not be covered .
•
Do not set the unit into operation, and im-
mediately disconnect the mains plug from the
mains socket if
1 . there is visible damage to the unit or to the
mains cable,
2 . a defect might have occurred after a drop
or similar accident,
3 . malfunctions occur .
The unit must in any case be repaired by skilled
personnel .
•
Never pull the mains cable to disconnect the
mains plug from the mains socket, always
seize the plug .
•
A damaged mains cable must only be replaced
by skilled personnel .
•
For cleaning only use a dry, soft cloth, never
use chemicals or water .
•
No guarantee claims for the unit and no liabil-
ity for any resulting personal damage or mate-
rial damage will be accepted if the unit is used
for other purposes than originally intended, if
it is not correctly connected or operated, or if
it is not repaired in an expert way .
•
Important for U. K. Customers!
The wires in this mains lead are coloured in
accordance with the following code:
green / yellow = earth
blue = neutral
brown = live
As the colours of the wires in the mains lead
of this appliance may not correspond with the
coloured markings identifying the terminals in
your plug, proceed as follows:
1 . The wire which is coloured green and yel-
low must be connected to the terminal in
the plug which is marked with the letter E
or by the earth symbol ⏚, or coloured green
or green and yellow .
2 . The wire which is coloured blue must be
connected to the terminal which is marked
with the letter N or coloured black .
3 . The wire which is coloured brown must be
connected to the terminal which is marked
with the letter L or coloured red .
Warning – This appliance must be earthed .
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not harm-
ful to the environment .

Applications and Accessories

This amplifier with 4 independent outputs
. and an RMS output power of 120 W each is
especially designed for PA applications . Either
PA speakers (100 V or 70 V) or low-impedance
speakers (minimum impedance 4 Ω) can be used
at the output . Further equipment:
– 3 input channels with adjustable sensitivity
from line level to microphone level, with XLR /
6 .3 mm connectors;
phantom power (15 V) for each channel to be
switched on individually
– 2 input channels for signals with line level via
RCA connectors
– 1 input channel for announcement signals
with line level via screw terminals (PAGING)
– 1 desk microphone PA-4000PTT with talk but-
ton, to be connected (accessory)
– 32 zone-paging microphones PA-4000RC with
zone selection and status LEDs, to be con-
nected (accessory)
– input signals can be assigned to the 4 outputs
as desired
– 4 emergency microphones PA-4000FMP with
microphone and announcement recorder, to
be connected (accessory)
– Switching voltage for each of the 4 zones to
control emergency priority relays in case of
emergency
– 1 monitor output to check the outputs and
for recording purposes
– 1 internal monitor speaker
– signal chime, to be activated via additional
momentary pushbuttons, e . g . to precede an
announcement; the type of chime (2-tone,
4-tone, siren) can be selected internally
– siren sound for alarm via additional switch
– 4 reserve amplifiers to be connected; in case
of failure of an output, the unit is automat-
ically switched to the corresponding reserve
amplifier (only if 100 / 70 V speakers are used)
– input for a 24 V emergency power supply unit
for operation in case of mains failure
Important announcements will become more
intelligible when the inputs take different priori-
ties . Then the signals of an input of lower priority
