More Setup, calibrating and integration SV Sound
If you are running a pair of SVS subwoofers (fig. 2), you will need to use a standard
“Y” cable adapter (c.) The best adaptor to use for this task has one male RCA con-
nection and two female RCA outputs. From the “Y” cable you can run a standard
75 Ohm RCA to RCA signal cable (d.) to each sub, thus “splitting” the Low Fre-
quency Effects (LFE) and other bass signals from your receiver and effectively feed-
ing both subwoofers with the same signal.

Calibration
” isn’t only for tech minded folks, it’s
critical
to a proper configuration
of your home theater sound system. Fortunately, adjusting channel balance (what
“calibration” really is) is as simple to do as it is important. First though, simply make
sure your DD/DTS surround sound system is set up properly. We recommend you
consult your audio/video receiver (or processor) manual to refresh on the procedures
to do this. Generally, this requires ensuring the receiver’s test tones, or a special test
disk (like Ovation Software’s
Avia
) play back at the same volume from each of your
system’s speakers. That’s speakers at left, center, right, left surround and right sur-
round (and if equipped, center rear), plus the subwoofer. (More on sub level in a sec-
ond). Skip to page 9 (“Powered Box Features”) if you aren’t familiar with your sub’s
amp, and come back to calibration.
Some things to check as you get ready to calibrate:
•
Are your speakers set correct to the correct “size”?
Your receiver/processor
should allow you to indicate if your speakers are “Small” or “Large”. Selecting
the size accordingly will ensure bass goes to most appropriate speakers, and use
the subwoofer correctly too. Also, is your subwoofer turned “ON”? We don’t
mean “is your subwoofer
amplifier
on?” (that’ll be important later too) but
rather,
is your receiver sending a bass signal to your sub amp
? This can only

NOTE: Now is a good time to select if
you want “ON” (always on) or “AUTO
ON” which turns your sub on only
when a bass signal is present.
