If your preamplifier does
not have a sub/LFE output,
you can use “Y” cables to
send its main outputs to
both the subwoofer and
your amplifier.
The subwoofer will play
the low frequency range
and your front speakers will
play the full range.
Although bass is
commonly distributed
evenly between left and
right channels (L+R bass),
movie soundtracks often
contain differential (L-R)
bass. The opening scene in
“Top Gun”, for example,
has loads of L-R bass
information. If this is not
preserved, the bass in
these scenes sounds
anemic. The Sunfire
Subwoofer utilizes
differential gain on the left
and right inputs to retain
both the L+R and L-R
information. Therefore,
systems which do not have
a dedicated sub/LFE output
should use
both
the left
and the right inputs as
shown, for the greatest
bass impact.
An alternative connection method
without using Y cables is shown on the
next page.
If your preamp/receiver has a
dedicated sub/LFE output, then only the
Left (Mono) input is used, as shown on
the previous page.
