6) If the connection module for the zone paging
microphone PA-6000RC has been inserted
before, the 2-pole line is already connected
to the jack CN 801 of the connection module
(dashed line in the layout plan on page 48) .
Disconnect the line from the connection module
and connect it to the jack CN 801 of the PA-6FR .
For this purpose connect the 2-pole line AN 801
of the PA-6FR to the jack CN 801 of the con-
nection module .
7) Place the jumper MS 401 of the amplifier to
position "FR" .
4.4.2 Operation
After setting the amplifier into operation, set the
switch ACTIVE (67) to position IN . Via input 1 make
an announcement at the required volume . In the
basic setting, when all DIP switches (68) are in the
upper position, the frequency shift is 2 Hz . If an
acoustic feedback should occur in spite of this
frequency shift, adjust a higher frequency shift with
the DIP switches .

5 Setting into Operation

5.1 Setting up the amplifier

The amplifier is designed for insertion into a rack
for units with a width of 482 mm (19"), but it can
also be used as a table top unit . In each case, air
must be able to circulate through all vents without
obstruction so that a sufficient cooling of the power
amplifier is ensured .
5.1.1 Rack installation
For rack mounting 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 hot air blown out at the side of the ampli-
fier must be dissipated from the rack; otherwise,
heat will accumulate in the rack which may not
only damage the amplifier but also other units in
the rack . In case of insufficient heat dissipation,
install a ventilation unit into the rack .
5.2 Adjusting the chime sound and the
priority of the insertion module
Prior to the installation of an insertion into the com-
partment (1), adjust the two jumpers MS 1 (chime)
and MS 2 (priority of the insertion), see layout plan
on page 48 . These are no longer accessible when
an insertion is installed .
1) Disconnect the amplifier from the mains and
from the emergency power supply .
2) Screw off the cover (1) for the insertion .
3) Adjust the chime sound with the jumper MS 1
position "4T": 4-tone chime
position "2T": 2-tone chime
4) Adjust the priority for the insertion module with
the jumper MS 2:
po sition "SLAVE" (factory setting):
The signal of the insertion has lowest priority .
po sition "PRI TO PACK":
The signal of the insertion has 2
adjustment must be selected, for example, if
annoucements stored via the zone paging
microphone PA-6000RC are to be called from
the digital message memory PA-1120DMT .
An overview of all possible priorities is given in
chapter 5 .4 "Defining the priority of the input
signals" .
5) If no insertion is installed, screw on the cover (1)
again .

5.3 Making connections

Any connections should only be made by quali-
fied personnel and in any case with the amplifier
switched off!
Numerous connections, e . g . those for the
speakers, are below the protective cover (22) . For
connection, screw off the cover .
WARNING Never operate the amplifier without
terminals (23, 25) . After connection, always replace
the cover to prevent any contact with the terminals .
5.3.1 Speakers
1) Either connect 100 V speakers for the six PA
zones to the screw terminals SPEAKER ZONES
ATT . OUTPUTS (23)
Attention! Each of the six zone outputs
allows a maximum load of 100 W RMS by the
speakers . However, the admissible total load
must not be exceeded in any case:
PA-6240 240 W RMS
PA-6480 480 W RMS
PA-6600 600 W RMS
or a speaker group with a total impedance of
4 Ω as a minimum to the screw terminals LOW
IMP 4 Ω (24) [when the 100 V outputs (23 and
25) are not used; otherwise, the amplifier will
be overloaded] . The zone volume switches (2)
do not affect this output .
2) Additional 100 V speakers which should always
be switched on independent of the zone but-
tons (3) and whose volume is not to be reduced
by the zone volume switches (2), may be con-
nected to the screw terminals HIGH IMP 100 V
(25) . The total load of all connected speakers
must, however, not exceed the amplifier power
(see note "Attention!") .
3) When connecting the speakers, always observe
the correct polarity, i . e . connect the positive
contact of the speakers each to the upper ter-
minal . The positive contact of the speaker cables
is always especially marked .
5.3.2 Microphones
Connect three microphones with an XLR or 6 .3 mm
plug to the combined XLR / 6 .3 mm jacks (42) of the
inputs 1 to 3 .
1) When connecting a microphone, turn the cor-
responding control GAIN (43) to the right stop
to position "−50" .
2) When using a phantom-powered microphone
(e . g . PA-4000PTT), switch on the 12 V supply
with the corresponding button PHANTOM
POWER (44) .
Caution! Only actuae the switch with the am-
plifier switched off (switching noise) . With the
button pressed, no unbalanced microphone
must be connected to the corresponding input;
otherwise, this microphone may be damaged .
3) For the priority of a microphone, set the corre-
sponding DIP switch MIC PRIORITY (34) to the
position ON (also see chapter 5 .4) .
priority . This
nd
Notes:
1 . When using the desk microphone PA-4000PTT or
PA-4300PTT, the input 1 must not be used as this
input is connected in parallel to the input (46) for the
PA-4000PTT and with the input (45) for the
PA-4300PTT .
2 . If a zone paging microphone PA-6000RC is connected,
the input 2 must not be used because it is in parallel
to the input for the PA-6000RC (via the corresponding
connection module) .
the protective cover (22) . During op-
eration, dangerous high voltages up
to 100 V are present at the speaker
5.3.3 Desk microphone PA-4000PTT
or PA-4300PTT
The desk microphones PA-4000PTT and PA-4300PTT
[separately available as accessories] have been
especially designed for this amplifier .
1) Use the RJ-45 jack PTT REMOTE to connect the
microphone PA-4000PTT to the jack PA-4000PTT
(46) of the amplifier or
use the jack OUTPUT to connect the microphone
PA-4300PTT to the jack PA-4300PTT (45) of the
amplifier .
2) It is possible to connect two additional micro-
phones of the model PA-4300PTT: Connect the
jack LINK of the first microphone to the jack
OUTPUT of the second microphone . Proceed in
the same way to connect the third microphone
to the second one .
3) Press the button PHANTOM POWER (44) of
input 1 and turn the corresponding GAIN con-
trol (43) fully to the right to the position "−50" .
Notes:
1 . Input 1 is now connected in parallel to the jacks for
the desk microphones and must therefore not be used
for any other input signals .
2 . The overall length of the microphone cable must not
exceed 1000 m .
5.3.4 Units with line output / recorder
Five units with line level (e . g . CD player, radio,
mixer) may be connected to the inputs 1 to 5 .
Exceptions: Do not use input 1 when connecting
a desk microphone to the jack PA-4300PTT (45) or
PA-4000PTT (46) and do not use input 2 when op-
erating the zone paging microphone PA-6000RC!
For background music the inputs 4 and 5
[RCA jacks LINE IN (41)] should be used because
these have lowest priority .
1) When connecting the inputs 1 to 3 via the com-
bined XLR / 6 .3 mm jacks (42), turn the corre-
sponding control GAIN (43) to the left stop to
position "−10" . Do not press the corresponding
button PHANTOM POWER (44) .
When connecting a stereo unit to one of
the inputs 1 to 3, use a stereo mono adapter
(e . g . SMC-1 from MONACOR) and an adapter
cable (e . g . MCA-300 from MONACOR); other-
wise, the signals of the stereo centre cancel each
other mutually .
2) If one of the inputs 1 to 3 should take priority
over the other two, set the corresponding DIP
switch MIC PRIORITY (34) to position ON . The
inputs 1 to 3 always take priority over the inputs
4 and 5 (see chapter 5 .4) .
3) A recorder may be connected to the jacks REC
(40) . The recording volume is independent of
the control MASTER (17) and the zone volume
switches (2) .
5.3.5 Inserting an equalizer or another unit
For external sound effect e . g . an equalizer may
be inserted via the jacks AMP IN – PRE OUT (39):
Connect the input of the unit to the jack PRE OUT
and the output to the jack AMP IN .
Note: A signal interruption occurs in the amplifier if only
jack AMP IN is connected or if the inserted unit is not
switched on, if it is defective or not correctly connected .
Then the speakers remain mute .
5.3.6 Additional amplifier
If more speakers are required than admissible for
the amplifier, another amplifier is necessary . Con-
nect the input of the additional amplifier to the
jack PRE OUT (39) or REC (40) . The signal for the
additional amplifier is not affected by the controls
MASTER (17) or by the zone volume switches (2) .
