PA Speaker System
with 370 W Amplifier
These operating instructions are intended for
users with basic knowledge in audio tech-
nology. Please read the instructions carefully
prior to operation and keep them for later
reference.
1 Applications
The speaker system PAK-312M/SW is suited for
numerous PA applications and can be used in
fixed installations and for mobile applications. It
is possible to use the speaker system as a floor
monitor or to place it on a speaker stand using
the stand sleeve.
The speaker system is designed as a 12/2 full-
range bass reflex system and is equipped with a
30 cm bass speaker (12") and a coaxial 25 mm
horn tweeter (1"). A digital amplifier (class D,
300 W) is used for bass frequencies, and an
analog amplifier (class A /B, 70 W) is used for high
frequencies. The audio signals pass a digital signal
processor (DSP) including a signal limiter.

3 Connections and Control Elements
Prior to connecting or changing connections,
.
always switch off the speaker system and the
units to be connected!
1 Input signal switch to switch between micro-
phone level and line level for input A
2 Switch for sound adjustment
MUSIC
= music reproduction
FLAT
= no sound modification
LOWCUT = filter for suppressing low frequen-
cies (≤ 120 Hz) activated
3 LED indicators
ON = power indicator
SIG = signal indicator
CLIP = overload indicator
4 Volume control MASTER
CAUTION Never adjust a very high vol-
volumes which do not seem to be that high
any more after some time. Therefore, do not
further increase a high volume after getting
used to it.
5 POWER switch
6 Inputs (XLR /6.3 mm jack, bal.) to connect units
with line outputs (mixer, MP3/CD player, etc.)
When the input signal switch (1) has been set
to the position MIC, a microphone can be con-
nected to the upper jack A.
7 Feed-through outputs
At these outputs, the signals of the corre-
sponding input jack (6) are available so that
they can be sent to another active speaker sys-
tem, for example.
8 Output jack MIX OUT
At this jack, the mixed signal of the two input
jacks (6) is available; the level depends on the
position of the control MASTER (4).
