More Setup, calibrating and integration
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.
!ampNOTE: 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.

“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 (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 speakers, plus the subwoofer . (More on sub level in a second). Skip now to page 7 (“Powered Cylin- der 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
