The input channels CH1 to CH4 are of
medium priority, i. e. their input signals will
take priority over the channels CH5 and CH6
but will be interrupted by announcements that
are made via the zone paging microphones
PA-4000RC or the desktop microphone PA-
4000PTT.
For input signals that demand the highest
priority, use the input PAGING (26) with plug-
in screw terminals (e. g. for a microphone
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 (
table fig. 5 in chap-
ter 3).
5.3 Direct inputs
When a signal with line level shall be audible 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 con-
nected via 2-pole 6.3 mm plugs. The control
LEVEL of the zone will have no effect on the vol-
ume of this input signal; it must be adjusted via
the output level of the signal source.
5.3.1
Setting the priority for the direct inputs
Using jumpers, it is possible 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).
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:
High priority
(PRIORITY)
Low priority
(SLAVE)
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 announce-
ments are to be audible 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 audible can be selected at the
respective PA-4000RC. Up to 32 PA-4000RC
may 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 connection
module is equipped with two RJ45 jacks (27); a
PA-4000RC can be connected to each of these
jacks. An additional zone paging microphone
can be connected to each zone paging micro-
phone until a maximum of 32 zone page micro-
phones 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 termination;
when both jacks are used, rearrange the
jumper to the position OFF:

3) Slide the module into the opening on the rear
side of the mixer, making sure that the con-
nector 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 module to
the RJ45 jack LINK (45) of the (first) PA-
4000RC by means of the cable supplied, for
example. If required, connect the jack INPUT
(46) to the jack LINK of another PA-4000RC
etc. until all units are connected in a chain.
The total line length must not exceed 1000 m.
2) To prevent interference in signal transmis-
sion, make sure that the line is correctly ter-
minated: 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 TERMINA-
TION of the DIP switch block (38) to the lower
position (ON). At all the 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 mod-
ule) or when more than 10 PA-4000RC are
connected. In this case, connect an addi-
tional power supply unit with 24 V
to the 11
th
PA-4000RC or to the zone paging micro-
phone 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
paging 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
Setting unit addresses
To enable communication between the mixer and
the zone paging microphones, the PA-4000RC
connected must have different data bus ad-
dresses. 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 opera-
tion 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 out-
put.
5.7 Amplifiers
Connect the power amplifiers for the four PA
zones to the XLR jacks OUT (16). Here, the
mixed signals for the respective zone are avail-
able as balanced signals with line level.
