will be required when 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 ter-
mination
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 con-
nected 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
sound first when the button TALK (43) is
pressed
PRIORITY – in the position ON, 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 an-
nouncement is being made via a different
PA-4000RC, the LEDs for the respective zones
will start flashing
EMER . – without any function when PA-
4000RC is used with 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

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! There is a risk of electric
shock .
•
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) .
•
Do not place any vessels filled with liquid on
the unit, e . g . a drinking glass .
•
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 ac-
cident,
3 . if malfunctions occur .
In any case, the unit must be repaired by skilled
personnel .
•
Never pull the mains cable to disconnect the
mains plug from the socket, always seize the
plug .
•
For cleaning only use a dry, soft cloth; never
use water or chemicals .
•
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 opera-
tion definitively, dispose of the unit
in accordance with local regulations .

Applications and Accessories

This signal mixer has specially been designed for
PA systems . It is inserted before the PA power
amplifiers and allows for connection of up to
4 microphones (also phantom-powered micro-
phones) . As an alternative, it is possible to con-
nect audio units with line level output to the
inputs 1 to 4 . Additional units with line level
output can be connected 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 announcement 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 checking the
outputs and for 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
indicators 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 follows:
.
Priority Input
1 (high) PA-4000PTT, PAGING,
LOCAL INPUT (PRIORITY)
2 PA-4000RC (PRIORITY = ON)
3 PA-4000RC (PRIORITY = OFF)
4 CH1, CH2, CH3, CH4
5 CH5, CH6
6 (low) LOCAL INPUT (SLAVE)
⑤ Input priorities

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 RU (rack units)
= 89 mm are required .

Connections

Prior to connecting units or changing any exist-
ing connections, disconnect 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
control 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 when 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
combined XLR / 6 .3 mm jacks (22) of the
inputs CH1 – CH4 . Turn the control for the
input gain GAIN (23) towards "LINE" . If re-
quired, readjust the control during operation .
(If the signal via this input is not loud enough,
turn the control clockwise; if the sound is dis-
torted, 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 . Of course,
audio sources with unbalanced signals can
also be connected to one of the RCA jacks
(18) of channel CH5 or CH6 .
The input channels CH1 to CH4 are of
medium priority, i . e . their input signals will
