1.4 Zone paging microphone
PA-4000RC
(separately available accessory)
34 Indicator POWER / CPU ERROR will light up
when the supply voltage is available; it will
start flashing in case of a malfunction of the
microprocessor in the PA-4000RC
35 Indicator MIC FAULT / LOW VOLTAGE will
light up in case of a microphone failure; it will
start flashing when the supply voltage is too
low
36 Indicator SIGNAL will light up when a micro-
phone signal is available
37 Jack 24 V
to supply additional voltage via a
power supply unit with a low-voltage plug
5.5/2.1 mm (exterior / interior diameter) and
any polarity; the additional power supply unit
will be required when the power supply via
the mixer does not suffice (e. g. when more
than 10 PA-4000RC are connected or when
the cable length exceeds 500 m)
38 Switches for the address and the line termi-
nation
I.D – prior to connection to the mixer, use
these 5 switches to set different addresses at
all PA-4000RC (
chapter 5.5.3)
TERMINATION – at the final PA-4000RC
connected in a chain, set the switch to ON in
order to activate the terminating resistor
39 Switches
CHIME – in the position ON, a chime will first
sound when the button TALK (43) is pressed
PRIORITY – in the position ON, the PA-
4000RC will take priority over the other units
where this function has not been activated
and will interrupt their announcements
COMPRESSION – in the position ON, the
dynamics of the microphone signal will be
attenuated in order to reduce distortions
when announcements are being made in a
loud voice
40 Microphone cartridge with windshield
41 Buttons to select the announcement zones,
each with the following status indicators:
BUSY – will light up when the zone for an
announcement has been selected; if an
announcement is being made via a different
PA-4000RC, the LEDs for the respective
zones will start flashing
EMER. – without any function when the
PA-4000RC is used with the PA-6040MPX
42 Button ALL CALL to select/deselect all zones
for an announcement at the same time
43 Button TALK; to make an announcement,
keep the button pressed and, if applicable,
wait for the chime
The LED indicator above the button will light
up while the button is being pressed; the
other input signals of the mixer (e. g. music)
will be muted to make the announcement
easier to understand.
44 Control AUDIO LEVEL to adjust the volume
of the announcement
45 RJ45 jack LINK for connection to a jack
INPUT (27) of the connection module at the
mixer or to the jack INPUT (46) of another
PA-4000RC
46 RJ45 jack INPUT to connect another PA-
4000RC

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 all operations
described in these instructions
where the unit must be opened to
skilled personnel! Inexpert han-
dling of the unit may result in
electric shock.
G
The unit is suitable for indoor use only. Protect
it against dripping water and splash water,
high air humidity and heat (admissible ambi-
ent temperature range 0 – 40 °C).
G
Do not place any vessels filled with liquid on
the unit, e.g. a drinking glass.
G
Do not operate the unit and disconnect it from
the mains
1. if the unit or the mains cable is visibly dam-
aged,
2. if a defect might have occurred after the unit
was dropped or suffered a similar accident,
3. if malfunctions occur.
In any case the unit must be repaired by
skilled personnel.
G
Never pull the mains cable for disconnecting
the mains plug from the socket, always seize
the plug.
G
For cleaning only use a dry, soft cloth; never
use water or chemicals.
G
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.
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not harmful
to the environment.
3 Applications and Accessories
This signal mixer has specially been designed
for PA systems. It is inserted before the PA pow-
er amplifiers and allows for the connection of up
to 4 microphones (also phantom-powered ones).
As an alternative, it is possible to connect audio
units with line level output to the inputs 1 and 4.
Additional units with line level output can be con-
nected to the inputs 5 and 6. For each input, it
can be defined to which of the 4 outputs (PA
zones) the signal shall be routed. For announce-
ment signals with line level, an additional input
with plug-in terminal screws is available.
An announcement can be preceded by a
chime tone. A monitor output for output checking
and recording purposes is available.
To ensure continued operation after a mains
failure, the mixer can be connected to a 24 V
emergency power supply unit.
To expand the announcement options, a
desktop microphone PA-4000PTT with a talk
button and up to 32 zone paging microphones
PA-4000RC with zone selection and status indi-
cators can be connected.
Input prioritisation will add to the audibility of
important announcements: Signals from an input
of lower priority will automatically be muted when
an announcement via an input of higher priority
is being made. The priority structure is as fol-
lows:
.

4 Setup Options
The unit is designed for installation into a rack
(482 mm/ 19"), but may also be used as a desk-
top unit. For rack installation, 2 RS (rack spaces)
= 89 mm are required.
5 Connections
Prior to connecting units or changing existing
connections, disconnect the PA-6040MPX from
the power supply and switch off the units to be
connected.
5.1 Microphones
Microphones with an XLR plug or 6.3 mm plug
can be connected to the combined XLR / 6.3 mm
jacks (22) of the inputs CH1 – CH4.
1) Turn the control for the input gain GAIN (23)
towards "MIC". If required, readjust the con-
trol during operation. (If the announcement
via this input is not loud enough, turn the con-
trol clockwise; if the announcement is dis-
torted, turn the control counter-clockwise.)
2) If a microphone requires phantom power,
engage the switch PHANTOM (21). The
phantom power will only be available at the
XLR contacts of the jack.
CAUTION!
1. Actuate the switch only when the unit has
been switched off or the input has been
muted (switching noise).
2. Do not connect an unbalanced micro-
phone when phantom power has been
activated; otherwise, the microphone may
be damaged.
5.2 Audio sources with line level
1) Connect units with a mono output to the com-
bined XLR / 6.3 mm jacks (22) of the inputs
CH1 – CH4. Turn the control for the input gain
(23) towards "LINE". If required, readjust the
control during operation. (If the signal via this
input is not loud enough, turn the control
clockwise; if the sound is distorted, turn the
control counter-clockwise.)
Disengage the switch PHANTOM (21),
unless the audio source explicitly requires
phantom power (phantom power only at the
XLR contacts of the jack).
The jacks are designed for balanced sig-
nals. Audio sources with unbalanced signals
can be connected via 2-pole 6.3 mm plugs or
via an XLR plug where the contacts 1 and 3
are connected with each other. The audio
sources with unbalanced signals can of
course also be connected to one of the RCA
jacks (18) of the channel CH5 or CH6.
