If you are running a pair of SV 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 connection and two female RCA outputs.
(Radio Shack ® stocks them.) From the “Y” cable you can run a stan-
dard 75 Ohm signal cable (d.) to each sub thus “splitting” the Low Fre-
quency Effects (LFE) and other bass signals from your receiver, thus
feeding both subwoofers.

alibration” isn’t only for tech minded folks, it’s critical to a proper
configuration of your home theater sound system. Fortunately, channel
balance (calibration) is as easy to do as it is important. The first order
of business is making 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

) plays back at the same volume from each of
your system’s full range speakers. That’s left, center, right, left sur-
round and right surround speakers, plus the subwoofer . (More on sub
level in a second). Skip to page 7 (“
Powered Cylinder Amp
”) 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 your system:
•
Are your speakers set correct to the correct “size”? Your receiver/
processor might allow you to indicate if your speakers are “Small” or

NOTE: Be sure to keep the power volt-
age switch in the correct position (your
sub is 110 volt or 220 volt capable).
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.
