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 (d.) 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 (e.) 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.
!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.

“Calibration”: This 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 impor- tant! 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 spe- cial test disk (like Video Essentials or Avia) play 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 (“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 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 appro- priate speakers, and use the subwoofer correctly too. In most instances set-
