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.

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” 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
