prior to operation and keep them for later ref-
erence .
All operating elements and connections de-
scribed can be found on the fold-out page 3 .

outputs Z1 to Z4, each for the input channels
CH1 to CH5
EMER . / FAULT – briefly lights up at switch-
on when an emergency microphone unit
PA-4000FMP has been connected for this
PA zone and a fault occurs at the emergency
microphone unit during operation
PROTECT – briefly lights up at switch-on and
in case of failure of an amplifier, e . g . by over-
load or overheating
CLIP – lights up when the amplifier is over-
loaded . In this case attenuate the volume of
this output with the control (11) or the vol-
ume of the inputs with the controls LEVEL (9) .
0 / −6 /−10 dB – show the output level
PWR – indicates the operating voltage of the
respective output amplifier

input PAGING (30)
Note: If an emergency power supply is connected
to the terminals 24 V⎓ (19), the amplifier cannot
be switched off
(230 V/ 50 Hz)

supply (⎓ 24 V)
20 Plug-in screw terminals to connect of the
speakers and a 100 V reserve amplifier, each
for the outputs Z1 to Z4; with the terminals
removed, a jumper to select the rated output
voltage is accessible (

chapter 5 .1 .1)
21 Plug-in screw terminals 24 V⎓ EMER . OUT
(each for the outputs Z1 to Z4) supply a
switching voltage when an emergency sit-
uation is signalled via an emergency micro-
phone unit PA-4000FMP;
here emergency priority relays of volume
controls inserted may be connected
22 Plug-in screw terminals PRE OUT with the
mixed signals (line level, balanced), each for
the zones Z1 to Z4, to pass on the signals to
the reserve amplifiers or additional amplifier
systems to provide sound to larger areas
23 Input EMERGENCY IN as an RJ45 jack for
connection of an emergency microphone
unit PA-4000FMP (each for the zones of the
outputs Z1 to Z4)
24 RCA jacks, each for the input channels CH4
and CH5; the jacks are available for stereo
signal sources as L (left) and R (right) . The
amplifier is monophonic; therefore, the ste-
reo signals are internally transformed into a
mono signal .
25 RCA outputs REC to record an output signal
selected with the selector switch RECORD-
ING / MONITOR (4); the jacks are available for
stereo recorders as L (left) and R (right) . The
amplifier is monophonic; therefore, the sig-
nals at the two jacks are identical .
26 Output MONITOR as a 2-pole 6 .3 mm jack for
connection of a monitor system to check the
outputs; the jack receives the same signal as
the outputs REC (25)
27 Switch PHANTOM POWER, each for the
input channels CH1 to CH3; with the switch
engaged, a voltage of ⎓ 15 V for phantom-
powered microphones is available at the XLR
contacts of the input jack (28)
28 Input as a combined XLR / 6 .3 mm jack, bal-
anced, each for the input channels CH1 to
CH3
29 Control GAIN to adapt the input sensitivity
to the signal source (microphone level to line
level), each for the input channels CH1 to
CH3
30 Plug-in screw terminals PAGING for connec-
tion of a signal source with line level output,
as an alternative to the desk microphone
PA-4000PTT, for announcements of highest
priority
31 Plug-in screw terminals for connection of mo-
mentary pushbuttons to activate the chime,
each for the input channels CH1 to CH3 and
for connection of a switch to activate / deac-
tivate a siren for all outputs
32 RJ45 jack for connection of the desk micro-
phone PA-4000PTT
1.2.1 Connection module for the zone-
paging microphone PA-4000RC
(supplied with the PA-4000RC)
33 RJ45 input jacks INPUT 1 and INPUT 2 for
connection of up to 32 zone-paging micro-
phones PA-4000RC; when making the con-
nections, make sure that the line termination

is correct (
