1 Overview

1.1 Front panel

1 Equalizer controls HIGH, MID and LOW;
one each for the inputs CH 1 to CH 4
2 Volume controls for the corresponding
input signal; one each for the inputs CH 1
to CH 8
3 LED indicators CLIP and SIG; one each for
the inputs CH 1 to CH 8
CLIP: Will light up briefly to indicate that
the maximum undistorted signal
level has been reached . If it lights
up more frequently, the input is
overloaded; in this case, turn back
the control GAIN (21) accordingly
SIG: Will light up when a specific signal
level has been reached at the cor-
responding input
4 Zone buttons Z 1 and Z 2 (PA-M412: Z 1 - Z 4)
to switch the input signal to the PA
zone(s) desired; one each for the inputs
CH 1 to CH 8
5 Equalizer controls HIGH and LOW for the
individual PA zones
6 LED indicators for the individual PA zones
PROT: Will light up when, in case of over-
heating or overload, the protective
circuit has switched off the speak-
ers
CLIP: Will light up briefly to indicate that
the maximum undistorted signal
level has been reached . If it lights
up more frequently, the zone is
overloaded; in this case, turn back
the control ZONE (8) accordingly
0, -10, SIG: Level indicators for the zone
7 Buttons MUTE to mute the individual
zones
8 Controls ZONE to adjust the volume in the
individual zones
9 Selector switch PFL/AFL for the monitor
function with the monitor speaker (12)
PFL: The zone selected will be moni-
tored ahead of the volume control
ZONE (8); the signal will be audible
even when the volume control is
turned to minimum or when the
button MUTE (7) is pressed
AFL: The zone will be monitored after
the volume control ZONE
10 Buttons Z 1 and Z 2 (PA-M412: Z 1 - Z 4) to
select the zone to be monitored via the
monitor speaker (12)
11 Volume control MONITOR for the monitor
speaker (12)
12 Monitor speaker to monitor the zones
13 Power switch and LED indicator POWER

1.2 Rear panel

14 Mains jack for connection to a mains
socket (230 V/ 50 Hz) via the mains cable
supplied
15 Mains fuse
Always replace a blown fuse by one of
the same type!
16 RJ 45 jack PAGING MIC for a zone paging
microphone PA-M4RC
17 Connection MUTE ALL for a switch to
mute all zones at the same time
18 RJ 45 jacks WALL MODULE; one each for
a wall module PA-M1WP per zone
19 Line level outputs of the individual zone
signals, e . g . to connect additional am-
plifiers
20 Speaker connections for the zones
The power rating for each zone is
PA-M224: 240 W
PA-M412: 120 W
Caution! The total load of the speakers
connected in a zone must not exceed
the rated power of the zone .
21 Controls GAIN to adjust the input gain;
one each for the inputs CH 1 to CH 8
When the gain is too high, the corre-
sponding LED indicator CLIP (3) will light
up frequently for high signal levels; in this
case, turn back the control accordingly .
22 Mono inputs LINE (6,3 mm jacks) for the
connection of audio units with line level
(e . g . microphone preamplifier)
CH 1 - 4 balanced
CH 5 - 8 unbalanced
23 Stereo inputs LINE (RCA jacks) of the in-
puts CH 5- 8 for the connection of audio
units with line level (CD / MP3 player, radio,
etc .)
24 XLR jacks MIC of the inputs CH 1 - 4 for
the connection of microphones
25 On / Off switch PHANTOM 2- 4 for the
phantom power supply of the micro-
phone inputs MIC (24) in the channels
CH 2 - 4
Caution! Only use this switch when the
amplifier has been switched off or when
the corresponding volume control (2)
has been set to minimum (switching
noise) .
