Is your receiver connected to the sub amp? Use a well-shieldedRCA cable sometimes called a “patch cord” to connect the subwoofer output of your DD/DTS receiver to either input jack of your subwoofer’s dedicated amplifier. As mentioned earlier, you’ll need to “split” the bass signal with a “Y Cable” if you bought a pair of subs. You only need feed one of the two inputs either Right or Left of any sin- gle Powered Box SVS however

But what’s “too high”?? Tastes vary, and so do movie soundtracks, but your SVS is capable of tremendous levels of low distortion, low frequency bass - far more than most commercial subs. Take advantage of this, especially if you like action movies with lots of “.1” channel LFE action, and give the sub a bit more “bump” during calibration also known as running the sub “hot”. Keep in mind too that the human ear is relatively insensitive to low frequencies. This, coupled with the fact most folks don’t watch mov- ies at Dolby Digital theater reference level loud!, means turning the bass up a few deci- bels usually yields a better movie sound experience

your sub, getting these bass wave forms to arrive in a complementary, enhancing fashion is the difficult job of the phase control. Essentially, “phase” varies the tim- ing of the bass waves coming from the sub. But don’t despair if you don’t hear much difference with changes to the phase knob - the effect of bass cancellation will vary by volume and frequency in your room, and no single setting is likely to ever be “perfect”. One technique to optimize phase is to find a nice “bassy” loop such as the menu of “Godzilla” and measure the loop’s SPL response at various points. As the loop runs, you can have an assistant adjust the phase control. When you see the most response on a given bass passage, typically that’s the setting with the least room-inducedcancellation for the frequencies of the demo loop
