Sunfire Subrosa SRS-210R - Manual (Page 15)

User's Manual
If your preamplifier does not
have a sub/LFE output, you can
use “Y” cables to send its main
outputs to both the subwoofer am-
plifier and your main 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 dedi-
cated 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.
