5.5.2 Connecting zone-paging microphones
1) Connect a jack of the module, e. g. via the
supplied cable, to the RJ45 jack LINK (51) of
the (first) PA-4000RC. If required, connect
the jack INPUT (52) to the jack LINK of
another PA-4000RC etc., until all units are
connected. The total length of the line must
not exceed 1000 m.
2) To prevent interference during signal trans-
mission, provide a correct termination of the
line. For this purpose set the switch TERMI-
NATION of the DIP switch block (44) to the
lower position (ON) at the last unit of the
chain (or at the two last units if INPUT1 and
INPUT2 are reserved at the module). For all
other units the switch must remain in the
upper position.
3) With a total cable length above 500 m (for
each input at the connection module) or if
more than 10 PA-4000RC units are con-
nected as a total, the power supply via the
PA-40120 is not sufficient. In this case con-
nect an additional power supply unit with
24 V
to the 11th PA-4000RC unit or the
zone-paging microphone which has more
than 500 m connection length to the amplifier.
Connect the power supply unit to the jack
24 V (43). The required dimensions of the
low voltage plug are 5.5 / 2,1 mm (outside /
inside diameter). The polarity is as desired.
The supply voltage is passed on via the
jack INPUT (52) also to zone-paging micro-
phones connected there so that these micro-
phones do not require an individual power
supply unit if the first power supply unit is of
sufficient dimensions (current consumption
for each PA-4000RC: 63 mA).
5.5.3 Adjusting the addresses of the units
Different data bus addresses have to be
assigned to all connected PA-4000RC units so
that the communication between the amplifier
and the zone-paging microphones will work.
This is made by means of the first 5 switches of
the DIP switch block (44) on the rear side of the
zone-paging microphones. Adjust the addresses
of the units continuously according to the table in
fig. 9.
Note: Always make the address adjustment with the
amplifier switched off as a change of the addresses will
not be recognized during operation.

5.6 Recorder, monitor system
It is possible to connect a recorder or another
audio unit with line input (e. g. a monitor system
to check the outputs) to the RCA jacks REC (25)
or to the 6.3 mm jack MONITOR (26). The RCA
jacks are provided for stereo recorders as L (left)
and R (right). As the amplifier operates mono-
phonically, the signals are identical at both jacks.
Adjust the selector switch RECORDING / MONI-
TOR (4) on the front side of the unit to define
which output signal is supplied.
5.7 Additional amplifier systems
The mixed signals for the respective zone are
present as balanced signals with line level at the
plug-in screw terminals PRE OUT (22). Here
additional amplifier systems for PA applications
of a larger area may be connected.
5.8 Momentary pushbutton for chime
activation, switch for siren
A CHIME may each be added to the signals of
the inputs CH1 to CH3 by an NO contact (nor-
mally open). Three different types of sound can
be selected (
chapter 5.8.1). To activate the
chime, connect e. g. a momentary pushbutton to
the corresponding contact of the plug-in screw
terminals CH1/ CH2 / CH3 (31) and the common
contact (2nd contact from above) [
For a siren sound of high volume in all zones
connect the upper two contacts of the plug-in
screw terminals via a switch. Contrary to the
sounds of the chime which end automatically
after shortly actuating the respective momentary
pushbutton, the siren can only be heard as long
as the switch is closed.

5.8.1 Selecting the sound of the chime
The sound of the chime can be adjusted inside the
amplifier. A 2-tone sequence, a 4-tone sequence
and a siren sound are available. The siren sound
is an emergency signal according to DIN 33 404/
EN 457 and independent of the siren function via
the siren switching contact described above.
Switch
1) Remove the housing cover of the amplifier.
2) A PCB with a jumper is provided in the rear
area, in parallel to the rear side of the unit,
near the inputs for CH1 and PAGING. Place
the jumper on the position corresponding to
the desired sound (

3) Close the housing with the cover.
5.9 Unit for evaluating a failure
If an amplifier output fails to operate or if a fault
occurs in one of the connected emergency
microphones, the relay FAULT (18) is switched
over. Here a unit for evaluating the fault, e. g. a
signal device, can be connected. The relay is
equipped with a floating switching-over contact
and has a rating of 24 V/ 500 mA.
5.10 Reserve amplifier
If the power amplifier of an output fails to oper-
ate, this is recognized automatically and a relay
is switched over to an additional amplifier. This
is only possible if the 100 /70 V output of the
PA-40120 is used.
1) Connect the input of the reserve amplifier to
2) Connect the 100 / 70 V output of the reserve
5.11 Emergency microphone unit
With this separately available accessory, emer-
gency announcements can be made at highest
priority. In addition, the emergency microphone

unit allows to record an announcement which is
automatically reproduced in an emergency situ-
ation via the amplifier system (for details
RJ45 jack EMERGENCY IN (23) for the corre-
sponding PA zone. The cable length may be
1000 m as a maximum. From a cable length of
500 m the PA-4000FMP must be supplied with
power via a power supply unit of its own
(
5.12 Emergency priority relays
Emergency priority relays serve to bridge vol-
ume controls inserted between the amplifier and
the speakers so that emergency announce-
ments are transmitted everywhere at maximum
volume. For each PA zone (Z1 to Z4) of the PA-
40120 an output 24 V EMER. OUT (21) is avail-
able for connecting emergency priority relays.
The rating of each output is 200 mA.
emergency microphone unit PA-4000FMP sig-
nals an emergency situation for this PA zone.
5.13 Power supply and
For continued operation of the amplifier in case
of mains failure, connect a 24 V emergency
power supply unit to the terminals 24 V

1. When a 24 V voltage is present, the amplifier is
immediately in operation and the power LED (14)
and the LEDs PWR (3) of the four outputs light
up. The amplifier cannot be switched off with the
switch POWER (15). The switch only serves to
switch over between mains power and emer-
gency power supply.
2. During emergency power operation the amplifier
supplies less power than during mains operation.
