CONNECTIONS

With its active crossover and numerous options for connecting and adjusting, the SWA 15
offers several benefits, especially regarding the integration with various types and sizes of
loudspeakers. You may tailor the level, the crossover frequency and the phase to the
main speakers of your choice, and you may choose freely if you want to use the subwoofer´s
built-in crossover network or use an external filter, which may be part of a surround amplifier.

In any case, the SWA 15 must be connected to a line level signal. This procedure takes
place by either using the  „AUDIO IN - LEFT/RIGHT”, „AUDIO IN - MONO” or „AUDIO IN
- LFE” sockets, and never more than one of these at the same time. It is important to make
sure that the level of the line signal chosen is being controlled with the volume control of
the system. The diagram below shows how the RCA phono sockets are wired inside the
subwoofer.

Connecting to a stereo signal with full frequency range:

If you want to connect the subwoofer directly to a preamp without built-in crossover network
of high quality, we recommend that you connect the subwoofer inputs „AUDIO IN - LEFT/
RIGHT” to a full-range signal from a normal preamplifier output. (See Fig. 1). This way, the
built-in crossover network of the subwoofer takes care of filtering the signal, resulting in
the subwoofer “only” reproducing the lowest notes of the signal.

When the subwoofer inputs „AUDIO IN - LEFT/
RIGHT” are fed a full-frequency stereo signal,
it is possible to tap a high-pass filtered signal
from the „AUDIO OUT - LEFT/RIGHT” sockets.
This  means  that  the  low  notes,  which  the
subwoofer is meant to handle, have been fil-
tered out. The high-pass filtered signal is then
fed to the power amplifier that drives the main
speakers, resulting in these speakers no longer
having to handle the demanding low frequen-
cies, which in turn means that the main speak-
ers will always sound  more clear.
