PA Mixing Amplifier
for 4 Zones
These instructions are intended for installers
of PA systems (chapters 1 – 7) and for users
without any specific technical knowledge
(chapters 1 – 3 and chapters 6 .2 – 6 .4) . Please
read the instructions carefully prior to opera­
tion and keep them for later reference .
All operating elements and connections
described can be found on the fold­out
page 3 .
1 Operating Elements and
Connections
1.1 Front panel
1 Tone controls TREBLE (high range) and
BASS (low range); one each for the inputs
CH 1 to CH 5
2 Controls GAIN for the input amplification;
one each for the inputs CH 1 to CH 5
3 Level indicator for the signal of the mon­
itoring speaker at the terminals MONI­
TOR (16)
4 POWER LED
5 POWER switch
6 Volume controls for the corresponding
input signal; one each for the inputs CH 1
to CH 5
7 Buttons ZONE SELECTOR Z 1 to Z 4 for
switch ing the corresponding input signal
to the desired PA zone(s);
one each for the inputs CH 1 to CH 5
8 Buttons MUTE for muting the correspond­
ing input; one each for the inputs CH 1
to CH 5
With the button pressed, the correspond­
ing input is muted and the LED above the
button MUTE lights up as an indication .
9 Volume control for headphones con­
nected to the jack PHONES (10)
10 Connection PHONES for headphones
Here, the signals of the PA zones are
available whose buttons MON (13) are
pressed .
11 Volume control for a monitor speaker
connected to the terminals MONITOR (16)
12
Level indicators for the corresponding
PA zone; one each for the zones 1 to 4
13 Buttons MON for switching the corre­
sponding signal of the PA zone to the
headphone output PHONES (10), to the
output MONITOR (16), and to the line
signal output MIX OUT (15);
one each for the zones 1 to 4
14 Volume controls of the corresponding PA
zone; one each for the zones 1 to 4
1.2 Rear panel
15 Line signal output MIX OUT for connec­
tion of another amplifier or a recorder
Here, the signals of the PA zones are
available whose buttons MON (13) are
pressed .
16 Terminal MONITOR for an 8 Ω monitor­
speaker
Here, the signals of the PA zones are
available whose buttons MON (13) are
pressed . The volume is adjusted with the
control MONITOR (11) .
17 Terminal PRIORITY for a switch: If the
switch is closed, only the signals of the
input CH 1 can be heard; the inputs CH 2
to CH 5 are muted .
18 Input TEL PAGING for a line level signal of
highest priority – see chapter 5 .5
19 Level selector switches for the inputs CH 1
to CH 3:
LINE
line level
PHANTOM microphone level, the phan­
tom voltage is available at the
corresponding input jack (29)
MIC microphone level, phantom
voltage switched off
Caution! Only actuate the switch when
the amplifier is switched off or the corre­
sponding control LEVEL (6) is set to zero
(switching noise) .
With the phantom voltage switched on,
do not connect a microphone with un­
balanced output . The microphone may
be damaged .
20 Outputs with line level for connection of
another am plifier or a recorder; one each
for the PA zones 1 to 4
21 Speaker terminals; one each for the PA
zones 1 to 4
The maximum RMS power at each zone
output must not exceed
40 W (PA­4040) or
120 W (PA­12040) .
Caution! For each zone, connect low
impedance speakers only (4 Ω, 8 Ω) or PA
speakers only (25 V, 70 V, 100 V); other­
wise, the amplifier will be damaged .
22 Air outlets for the temperature­controlled
fan
23 Clamping screw for a possible ground
connection
24
Mains fuse
Only replace a blown fuse by one of the
same type .
25
Mains jack for connection to a socket
(230 V/ 50 Hz) via the supplied mains cable
26 DIP switches ZONE
Set the switches of the zones to the lower
position ON for feeding the signal at the
terminals TEL PAGING (18) to the corre­
sponding PA zone – also see chapter 5 .5
27 RCA jacks for the inputs CH 4 and CH 5
for con nection of audio units with line
output (CD player, cassette recorder,
radio, etc .)
28 Volume control for the signal at the ter­
minal TEL PAGING (18)
29 Jacks for the inputs CH 1 to CH 3 (com­
bined XLR / 6 .3 mm jack, bal .) for connec­
tion of microphones or audio units with
line output
