take priority over the channels CH5 and CH6
but will be interrupted by announcements
that are made via the zone paging micro-
phones PA-4000RC or the desktop micro-
phone PA-4000PTT .
For input signals requiring the highest
priority, use the input PAGING (26) with
plug-in screw terminals (e . g . for a micro-
phone with preamplifier or for the line level
output of a telephone system) .
2) Connect units with a stereo output (e . g . CD
player) to the RCA jacks (18) of the input
CH5 or CH6 . In the PA-6040MPX, the two
stereo channels are mixed to a mono signal .
These inputs have the lowest priority and
will automatically be muted by a signal at
an input of higher priority (
in chapter 3) .
5.3 Direct inputs
When a signal with line level is to be heard in
one zone only, connect the signal source to the
jack LOCAL INPUT of the zone desired . The jacks
are designed for balanced signals . Audio sources
with unbalanced signals can be connected via
2-pole 6 .3 mm plugs . The control LEVEL of the
zone will have no effect on the volume of this
input signal; the volume must be adjusted via
the output level of the signal source .
5.3.1 Setting the priority for the direct inputs
Jumpers are used to define for each direct input
if its signal shall take priority over other signals or
not (
☞
table fig . 5 in chapter 3: LOCAL INPUT
PRIORITY/ SLAVE) .
WARNING The mixer must be opened for
this operation; therefore, it must
be performed by skilled person-
nel only! Prior to opening the
mixer, disconnect the mains plug from the
socket; otherwise, there will be risk of electric
shock!
1) Remove the housing cover from the mixer .
2) The jumpers are located on the front circuit
board behind the controls for the inputs CH1
to CH4:
⑥ Selecting the priority of a direct input
Rearrange the respective jumpers as required .
3) Close the housing again .
5.4 Desktop microphone PA-4000PTT
With this desktop microphone (separate acces-
sory), announcements of the highest priority
can be made . The PA zones where the an-
nouncements are to be heard are selected at the
PA-6040MPX .
Connect the PA-4000PTT to the RJ45 jack
"PA-4000PTT" (24) by means of the cable sup-
plied, for example . The length of the connection
line must not exceed 30 m .

5.5 Zone paging microphone
PA-4000RC
With this zone paging microphone (separate
accessory), announcements of high priority can
be made . The PA zone where the announce-
ments are to be heard can be selected at the
respective PA-4000RC . Up to 32 PA-4000RC can
be connected to a single PA-6040MPX .
5.5.1 Installing the connection module
First, install the connection module supplied with
the PA-4000RC in the mixer . Figure 2 shows the
mixer with the module installed . The connec-
tion module is equipped with two RJ45 jacks
(27); a PA-4000RC can be connected to each of
these jacks . An additional zone paging micro-
phone can be connected to each zone paging

microphone until a maximum of 32 zone page
microphones and the mixer are connected with
each other .
1) Screw off the two screws of the cover plate
(located to the right on the rear side of the
mixer) and remove the plate .
2) If only jack INPUT 1 of the two connection
jacks (27) is used, rearrange the jumper on
the circuit board of the connection module
to the position ON for a correct line termi-
nation; when both jacks are used, rearrange
the jumper to the position OFF:

with jumper for the terminating resistor
3) Slide the module into the opening on the
rear side of the mixer, making sure that the
connector on the module fits into the socket
of the mixer . Fasten the module with the two
screws .
5.5.2 Connecting zone paging microphones
1) Connect a jack of the connection mod-
High priority
ule to the RJ45 jack LINK (45) of the (first)
(PRIORITY)
PA-4000RC by means of the cable sup-
plied, for example . If required, connect the
jack INPUT (46) to the jack LINK of another
Low priority
PA-4000RC etc . until all units are connected
(SLAVE)
in a chain . The total line length must not
exceed 1000 m .
2) To prevent interference in signal transmission,
make sure that the line is correctly termi-
nated: At the final unit in the chain (or at
the final two units if INPUT 1 and INPUT 2 at
the module are used), set the switch TERMI-
NATION of the DIP switch block (38) to the
lower position (ON) . At all other units, the
switch must remain in the upper position .
3) The power supply via the PA-6040MPX will
not suffice when the total line length exceeds
500 m (for each input at the connection
module) or when more than 10 PA-4000RC
are connected . In this case, connect an ad-
ditional power supply unit with ⎓ 24 V to
the 11th PA-4000RC or to the zone paging
microphone with a connection line length of
more than 500 m to the PA-6040MPX .
Connect the power supply unit to the
jack ⎓ 24 V (37) . The required dimensions
of the low-voltage plug are 5 .5 / 2 .1 mm
(exterior / interior diameter) . The polarity is
as desired .
The supply voltage will be routed to the
zone paging microphones that are connected
to the jack INPUT (46) . Thus, these zone pag-
ing microphones do not require a power
supply unit of their own if the power supply
unit connected to the jack ⎓ 24 V provides
sufficient current (current consumption of
each PA-4000RC: 63 mA) .
5.5.3 Address assignment
To enable communication between the mixer
and the zone paging microphones, the PA-
4000RC connected must have different data bus
addresses . To assign the addresses, use the first 5
switches of the DIP switch block (38) located on
the rear side of the zone paging microphones .
Set the addresses continuously according to the
table in figure 8 .
Note: Always switch off the mixer prior to address
assignment; any address changes made during op-
eration will not be recognised .

5.6 Recorder, monitoring system
A recorder or another audio unit with line input
(e . g . a monitoring system for checking the out-
puts) can be connected to the RCA jacks REC
(19) or to the 6 .3 mm jack MONITOR (20) . LEFT
and RIGHT RCA jacks are provided for stereo
recorders . The mixer is monophonic; therefore,
the signals at the two jacks are identical .
The setting of the selector switch REC /
MONITOR (5) located on the front side of the
unit will determine the output signal for this
output .
