Connecting to a mono signal with full
frequency range:
If you want to connect the subwoofer to just
one channel, for instance when using two
units in a stereo set-up, and if you still want
to utilize the built-in crossover network of
the subwoofer to divide the frequency of the
signal as described in the section
concerning connection to a stereo signal,
the subwoofer input AUDIO IN - MONO
should be used. (See Fig. 2). As with the
stereo connection, the built-in crossover
networks of the subwoofer split the audio
signal, resulting in the subwoofer only
reproducing the low notes. From the output
socket AUDIO OUT -
LEFT a high-pass
filtered signal may be tapped, as when using
a stereo connection. Please note that there
is
no signal available on the AUDIO OUT -
RIGHT socket.
Connecting to a low-pass filtered mono
signal:
If you want to use the subwoofer with a sur-
round amplifier or other sound equipment
giving access to a filtered mono output for
subwoofer use, it may be advantageous to
connect this signal to the subwoofer´s input
marked AUDIO IN - LFE (See Fig. 3).
When the subwoofer is connected via
AUDIO IN - LFE, the SWA 15 crossover
network has no effect, meaning also that
there is
no signal available at the output
AUDIO OUT (See diagram on page 4). Any
adjustment of the crossover frequency must
take place elsewhere in the system, and the
manual for the relevant unit should be
complied with. When using the input socket
AUDIO IN - LFE, the level and phase
controls of the SWA 15 are still active, and
these should be adjusted as recommended
in the section concerning adjustments.
