INPUTS
TO FRONT SPEAKERS
If your preamplifi er does
not have a sub/LFE output,
you can use “Y” cables to
send its main outputs to
both the sub woof er and
your am pli fi er.
The subwoofer will play
the low frequency range
and your front speak ers will
play the full range.
Although bass is com-
mon ly dis trib ut ed evenly
between left and right
chan nels (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
in for ma tion. If this is not
preserved, the bass in
these scenes sounds ane-
mic. The Sunfi re Subwoofer
utilizes dif fer en tial gain on
the left and right inputs to
retain both the L+R and
L-R in for ma tion. There fore,
sys tems which do not
have a dedicated sub/LFE
output should use both
the left and the right inputs
as shown, for the great est
bass impact.
An alternative connection
method without using Y cables is shown
on the next page.
If your preamp/receiver has a dedi-
cated sub/LFE output, then only the Left
(Mono) input is used, as shown on the
previous page.
