for Speaker Systems
These instructions are intended for
non-professionals with basic knowledge in
DIY speaker building. Please read the in-
structions carefully prior to operation and
keep them for later reference.
1 Applications
This crossover network can be used to set up
a 2-way speaker system with a power capabil-
ity of up to 600 W. Its filter characteristics are
specially designed for PA bass speakers with a
diameter of 30 cm or 38 cm.
2 Important Notes
The crossover network corresponds to all rel-
evant directives of the EU and is therefore
marked with
.
•
The crossover network is suitable for indoor
use only. Protect it against dripping water,

No guarantee claims for the crossover net-
work and no liability for any resulting per-
sonal damage or material damage will be
accepted if the crossover network is used for
other purposes than originally intended, if it
is not correctly connected, if it is overloaded,
or if it is not repaired in an expert way.
If the crossover network is to be put
out of operation definitively, take it to
a local recycling plant for a disposal
which is not harmful to the environ-
ment.
3 Connection
1) Connect the speakers to the crossover net-
work (figs. 3 and 4).
B+
and B− = bass speaker
HB+ and H− = tweeter
HA+ and H− = tweeter when a speaker
The correct polarity of the tweeter de-
pends on the speakers used and on their
arrangement within the speaker system. To
determine the correct polarity, make sound
checks.
2) The pins IN are used as signal inputs.

3.1 Connection of a speaker L pad
A speaker L-pad (e. g. model series AT-62 ...
from MONACOR) can be used to perfectly
match the volume of the tweeter to the vol-
ume of the bass speaker. For this, the connec-
tion strip L-PAD is provided. The connection is
shown in fig. 4.
