1 Operating Elements
and Connections
1.1 Front side of the PA-40120
1 Tone controls BASS and TREBLE, each for
the input channels CH1 to CH5
2 Switch for the assignment of the input to the
outputs Z1 to Z4, each for the input channels
CH1 to CH5
3 Status LEDs, each for the outputs Z1 to Z4
EMER./ FAULT - shortly lights up when
switching-on if an emergency microphone
unit PA-4000FMP has been connected for
this PA zone and a fault occurs at the emer-
gency microphone unit during operation
PROTECT - shortly lights up when switch-
ing-on and in case of failure of an amplifier,
e. g. by overload or overheating
CLIP - lights up when the amplifier is over-
driven. In this case attenuate the volume of
this output with the control (11) or the volume
of the inputs with the controls LEVEL (9).
0/-6/-10 dB - show the output level
4 Rotary switch RECORDING / MONITOR for
the selection of one of the zone output sig-
nals to be sent to the outputs REC (25) and
MONITOR (26) and the integrated speaker (7)
5 SPEAKER switch to switch the integrated
speaker (7) on and off
6 Volume control for the integrated speaker (7)
[not for warning signals]
7 Speaker to check the outputs and for warning
signals
8 LED SIG. lights up when a signal is available
at the input (each for the input channels CH1
to CH5)
9 Volume control LEVEL, each for the input
channels CH1 to CH5
10 Switch with indicating LED to switch the input
on and off, each for the input channels CH1
to CH5
11 Control for the overall volume, each for the
outputs Z1 to Z4
12 Switch ZONES SELECTOR to select an out-
put for an announcement via the desk micro-
phone PA-4000PTT or via the input PAGING
(30)
13 Volume control for an announcement via the
desk microphone PA-4000PTT or via the
input PAGING (30)
14 POWER LED
15 Mains switch POWER
Note: If an emergency power supply is con-
nected to the terminals 24 V (19), the ampli-
fier cannot be switched off
1.2 Rear side of the PA-40120
16 Mains cable for connection to a socket
(230 V~ / 50 Hz)
17 Fuse for the 24 V emergency power supply
Only replace a blown fuse by one of the same
type!
18 Relay with a switch-over contact to signal the
failure of a unit, e. g. via a visual or acoustic
signal device; connection via plug-in screw
terminals
19 Screw terminals for an emergency power
supply (24 V )
20 Plug-in screw terminals for connection 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
(each for the outputs Z1 to Z4) supply a
switching voltage when an emergency situa-
tion 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 for PA application of 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 out-
puts 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). As the
amplifier operates monophonically, in each
case the mono sum will internally result from
the stereo signals.
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).
As the amplifier operates monophonically,
the signals are identical at both jacks.
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
powered microphones is present 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
EMER. OUT
for phantom-
