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 standard 75 Ohm RCA
to RCA signal cable (d.) to each sub, thus “splitting” the Low Frequency
Effects (LFE) and other bass signals from your receiver and effectively
feeding both subwoofers with the same signal.

isn’t only for tech minded folks, it’s
critical
to a proper
configuration of your home theater sound system. Fortunately, adjusting
channel balance (or calibration) is as easy to do as it is important. The
first order of business is making sure your DD/DTS surround sound sys-
tem 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
Video Essentials or Avia
) plays back at the same volume from
each of your system’s full range speakers. That’s left, center, right, left
surround and right surround (and if equipped, center rear) speakers, plus
the subwoofer . (More on sub level in a second). Skip to page 7

come back to calibration.

re your speakers set correct to the correct “size”?
Your receiver/
processor might allow you to indicate if your speakers are “Small” or
“Large”. Selecting the size accordingly will ensure bass goes to most appro-
priate speakers, and use the subwoofer correctly too. Also, is your subwoofer

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.
