Y CABLES
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 connec-
tion 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.
