2Safety Notes
The unit corresponds to all relevant directives
of the EU and is therefore marked with ..
WARNING The unit uses dangerous mains
voltage.. Leave servicing to
skilled personnel only and do
not insert anything into the
air vents.. Inexpert handling may result in
electric shock..
During operation, there is a hazard of con-
tact at the connections OUTPUT 70 V and
100 V (21) with a voltage of up to 100 V..
Always switch off the PA system before
making or changing any connections..
•The unit is suitable for indoor use only.. Pro-
tect it against dripping water and splash water,
high air humidity and heat (admis- sible
ambient temperature range 0 – 40 °C)..
•Do not place any vessels filled with liquid,
e. g.. drinking glasses, on the unit..
•The heat produced inside the unit must
be carried off by air circulation; never
cover the air vents (22) of the housing..
•Do not operate the unit or immediately
disconnect the mains plug from the socket
1. if the unit or the mains cable is visibly
damaged,
2. if a defect might have occurred after
the unit was dropped or suffered a
similar accident,
3. if malfunctions occur..
In any case, the units must be repaired
by skilled personnel..
•Never pull the mains cable to disconnect
the mains plug from the mains socket, al-
ways seize the plug..
•For cleaning only use a dry, soft cloth,
never use chemicals or water..
•No guarantee claims for the unit and no li-
ability for any resulting personal damage or
material dam-age- will be accepted if the unit
is used for other purposes than originally
intended, if it is not correctly connected,
operated or not repaired in an expert way..
If the unit is to be put out of oper-
ation -de-finitively, take it to a local
recycling plant for a disposal which
is not harmful to the environment..
3Applications
The amplifier has especially been de-signed for
setting up a PA system for general PA appli-
cations.. The different speaker outputs allow to
connect various speaker combinations (see fig..
3).. The speakers can be distributed to four PA
zones, and the volume of each zone can be
adjusted independently of the others..
It is possible to connect microphones
(CH 1 – 3) or units with line level output
(CH 1 – 5) to the five inputs which can be
mixed with each other.. All inputs can be as-
signed to the four PA zones independently of
each other.. An additional line level input is
provided- for emergency announcements or
other important announcements.. With a
separate switch it is possible to switch to this
input..
For monitoring the zone signals, outputs
for headphones and an 8 Ω monitor speaker
are provided-.. The zone signals may
individu- ally be fed via the outputs LINE OUT
(20) or mixed via the output MIX OUT (15) to
further amplifiers or to a recorder..
4 Setting up the Amplifier
The amplifier is provided for installation into
a rack for units with a width of 482 mm
(19”), but it can also be used as a table top
unit.. In any case, make sure that air will
circulate freely through all vents to provide
sufficient cooling of the unit..
4.1 Rack installation
Prior to installing the amplifier into a rack,
give priority to the inputs CH 1 and TEL
PAGING, if required.. Open the amplifier
for this purpose (chapter 6..1)..
For rack mounting 3 RS (3 rack spaces =
133 mm) are required.. To prevent the rack
from becoming top-heavy, the amplifier must
be inserted in the lower section of the rack..
The front panel alone is not sufficient for fixing
it safely.. In addition, lateral rails or a bottom
plate must secure the unit..
The air heated bythe amplifier must be
able to leave the rack; otherwise, this will
result in heat accumulation within the rack
which may not only damage the amplifier
but also other units in the rack.. In case of
in- sufficient heat dissipation, install a
ventilation unit into the rack..
5Connecting the Amplifier
All connections should only be made by
spe- cialized personnel and always with
the am- plifier switched off!
5.1 Speakers
Fig.. 3 on page 3 shows examples of
different possibilities of connection of the
speakers for each PA zone..
Caution! For each zone, connect low im-
pedance speakers only (4 Ω, 8 Ω) or PA
speakers only (25 V, 70 V, 100 V);
otherwise, the amplifier will be damaged..
However, it is possible to connect low
im-pe- dance speakers and PA speakers
in different zones..
When connecting PA speakers, make sure
that the RMS power at each of the four zone
outputs will not exceed 40 W (PA-4040) or
120 W (PA-12040).. When interconnecting
low impedance speakers, make sure that the
impedance will not fall below the value stated
at the terminal (4 Ω or 8 Ω)..
Connect the speakers to the terminal strips
OUTPUT (21): the negative connections to the
terminal “COM” and the positive con nections to
the corresponding terminal “4 Ω”, “8 Ω”, “25 V”,
“70 V”, or “100 V”.
5.2 Monitor speaker and headphones
To be able to monitor the signals of the PA
zones, it is possible to connect an 8 Ω
speaker to the terminals MONITOR (16) and
head- phones to the jack PHONES (10)..
5.3 Microphones
Up to three microphones with XLR plug or
6..3 mm plug may be connected to the in puts
CH 1 to CH 3 (29).. Set the input level switches
(19) to the corresponding position.. Only actuate
the switches when the amplifier is switched off or
when the corresponding control LEVEL (6) is set
to zero (switching noise)..
MIC for microphones which do not require
phantom power
PHANTOM for phantom-powered micro-
phones
Caution! Do not connect any microphones
with unbalanced output when the phan- tom
power has been activated.. These mi-
crophones may be damaged..
5.4 Units with line output
Up to five units with a line output (e. g.. CD
player, cassette recorder, radio) may be con-
nected to the inputs CH 1 to CH 5 (27 and
29).. For background music, it is best to use
the inputs CH 4 and CH 5.. These inputs may
be muted with a separate switch when e. g..
an announcement is made via the input CH 1
(see chapter 5..6).. The stereo signals fed to
the jacks “L” and “R” of the inputs CH 4 and
CH 5 are internally mixed to a mono signal..
When connecting to the inputs CH 1 to
CH 3, set the corresponding input level switch
(19) to the position LINE.. Only actuate the
switch with the amplifier switched off
(switch- ing noise).. For connecting a
stereo unit to the inputs CH 1 to CH 3, use
one input each for the right stereo channel
and the left ste- reo channel or use astereo
mono adapter (e. g.. SMC-1 from
MONACOR); otherwise, the signals of the
stereo centre will cancel each other out..

5.5 Connection for emergency
announcements or
a telephone systeme
For emergency announcements or for con-
nection to a telephone system, the amplifier is
provided with the input TEL PAGING (18)..
TEL. PAGING
T R G
➃Input and switch
for emergency
announcements
Signal
Feed the signal (line level, 40 mV – 1..5 V) via a
shielded audio cable to the terminal “R”..
Connect the ground and the shield to the ter-
minal “G”.. Connect a switch to the terminals “T”
and “G”.. The switch is used to release the
announcement, i. e.. the announcement signal
may always be available at the terminal “R”, but
it can only be heard when the switch is closed..
When the switch is closed, the sig- nals of the
inputs CH 2 – 5 can be muted at the same time,
see chapter 6..1..
Set the DIP switches ZONE (26) for the
zones where the emergency announcements
are to be heard to the lower position ON.. The
volume for these announcements is sepa-
rately adjusted with the control VOLUME (28)
on the rear side..
5.6 Switch for muting the
inputs CH 2 to CH 5
The inputs CH 2 to CH 5 can be muted to
gether with a single switch, e. g.. for
making an important announcement via
the input CH 1.. For this purpose, connect
a switch to the terminals PRIORITY (17)..
Note: When an announcement is made via the
input CH 1, the inputs CH 2 to CH 5 will be
automatically muted if priority is given to the
input CH 1, see chap ter 6..1..
5.7 Line signal outputs for further
amplifiers or a recorder
For connecting further amplifiers or a re-
corder, different line outputs are available:
LINE OUT (20)
The signals of the individual zones are present
at these four balanced outputs.. The signal level
depends- on the position of the corre- sponding
zone control LEVEL (14).. If the input of the unit
to be connected is unbalanced, connect the
input only to the terminals “+” (signal) and “G”
(ground).. Use these outputs:
1. to connect further PA amplifiers if more
speakers than permitted are required for
each PA zone..
2. to connect a recorder for recording the
signals of a zone..
MIX OUT (15)
Here the signals of the zones are present
whose buttons MON (13) are pressed. . If
several zones are selected at the same
time, the corresponding zone controls
LEVEL (14) define the mixing ratio of the
zone signals.. Use this output:
1. to connect an amplifier if e. g.. further
mon- itoring speakers are required..
2. to connect a recorder for recording the
signals of different zones..
5.8 Power supply
Finally connect the supplied mains cable to
the mains jack (25) first and then to a
socket (230 V/50 Hz).
6 Setting into Operation
6.1 Giving priority to the inputs
CH 1 and TEL PAGING
In the factory, the inputs CH 1 and TEL PAGING
(18) are adjusted in such a way that their signals
will be mixed with the other input channels..
When the jumper S701 inside the amplifier is
rearranged, the inputs CH 1 and TEL PAGING
will take priority over the inputs CH 2 – 5.. When
an announcement is made via the input CH 1 or
TEL PAGING, the signals of CH 2 – 5 will be
automatically muted during the announcement..
WARNING For rearranging the jumper
S701, the unit must be opened..
Only skilled personnel may do
this; inexpert handling may
result in electric shock..
1) Disconnect the mains plug from the socket..
2) Unscrew the housing cover..
3) Rearrange the jumper S701 from OFF
to ON (page 11, figure 5)..
4) Fasten the housing cover again..
6.2 Adjusting the volume and the
sound, switching the input signals
to the zones
1) To prevent switching noise, switch on
all other units of the PA system first..
2) Prior to switching on the amplifier for the first
time, set the four zone controls LEVEL (14)
to zero to prevent an excessive volume at the
beginning-.. Then switch on the amplifier with
the POWER switch (5).. The POWER LED
(4) lights up..
3) For basic setting of the input channels
a) set all controls GAIN (2), TREBLE
and BASS (1) to mid-position,
b) set all controls LEVEL (6, 14) to zero,
c) unlock all buttons MUTE (8) so that
the red LEDs above the buttons do
not light up,
d) unlock all buttons ZONE
SELECTOR Z 1 to Z 4 (7)..
4) Turn up the control LEVEL (6) of the input
which is to be heard at highest volume (e. g..
for an-nounce-ments) to approx.. 2∕3of the
maximum value.. With the buttons ZONE
SELECTOR (7), switch the input sig- nal to
the zones where it should be heard..
5) Adjust the desired volume for each zone with
the zone controls LEVEL (14).. The level
indicators (12) show the volume of the
zones.. The top red LED lights up when
the integrated limiter limits the volume
at the maximum level.. It should light up
with passages of highest volume for a
short time only.. If it lights up for a longer
time, turn back the corresponding zone
control LEVEL..
If the volume of the zones cannot be
adjusted in an optimum way because the
input signal is too low or too high, read-
just the input level with the corresponding
control GAIN (2) or LEVEL (6)..
6) Adjust the sound with the corresponding
controls TREBLE and BASS (1).. If
required, readjust the volume with the
control LEVEL (6)..
7) For feeding further input signals to
certain zones, press the corresponding
buttons ZONE SELECTOR (7).. With
these buttons the zones may be
configured differently.. Example:
–The announcements of input CH 1
are to be heard in all zones.
Press the buttons Z 1 to Z 4 of CH 1..

–The announcements of input CH 2 are
to be heard in zones 1 and 4 only.
Press the buttons Z 1 and Z 4 of CH 2..

–The background music of CH 4 is to
be heard in zones 1 and 2.
Press the buttons Z 1 and Z 2 of CH 4..

–The background music of CH 5 is to
be heard in zones 3 and 4.
Press the buttons Z 3 and Z 4 of CH 5..

8) Adjust the volume and the sound of further
input signals with the controls LEVEL (6),
TREBLE and BASS (1).. Turn the controls
LEVEL of the inputs not used to zero..
6.3 Muting inputs
For muting an input, e. g.. for switching off the
background music in case of an announce-
ment, press down the corresponding button
MUTE (8).. As an indication, the red LED above
the button lights up.. To switch on the input
again, unlock the button MUTE..
If a switch is connected to the terminals
PRIORITY (17), the inputs CH 2 to CH 5 can be
muted at the same time by closing the switch..
6.4 Monitoring the zone signals
Press down the buttons MON (13) of the PA
zones whose signals are to be monitored..
Ad- just the volume for the monitor speaker
con- nected to the terminals MONITOR (16)
with the control MONITOR (11) and the
volume for the headphones with the control
PHONES (9).. The signal for the monitor
speaker is shown by the level indicator (3)..
Notes:
1.. The volume for the headphones and the moni-
toring speaker also depends on the zone controls
LEVEL (14).. Whena control is set to zero, the signal
of the corresponding zone cannot be monitored
even if the button MON is pressed..
2.. The buttons MON are also used to switch the zone
signals to the output MIX OUT (15) –see chapter
5..7..
