Page 2 SV Subwoofers Welcome. From the entire SVS team, congratulations on your pur- chase of the standard in home theater and music bass! Your new subwoofer isn’t some generic, mass-produced box built someplace you can’t even find on a map. It’s made in Ohio (USA), by home audio enthusiasts... like you. Designed, tested and assem- bled by hand, while using state of the art automation and materials, your SVS is without a doubt one of the best investments you’ll ever make in bring

Page 3 SV Subwoofers About your SV Subwoofer No powered subwoofers look anything like them. And virtually none work like them either. SV Subwoofers are decidedly different. The best part? You could have spent much more and still not come close to the same bass performance our PC-Ultra line gives you. But what makes a subwoofer an SVS? Quality components, sane prices. You might be surprised at how inexpensive the components in some not-so-inexpensive subwoofers are. Make no mist

Page 4 SV Subwoofers Setup, calibrating and integration What’s to know? Well, first of all, setting up an SV Subwoofer is pretty darn easy. There are a few key things to get right though, if you want to get the most out of your sub… Unpacking. You’re probably eager to fire up your sub (we’re the same way), but take time to carefully unpack your sub. Set the box and other protective shipping coverings aside, just in case you need to return the sub for any reason. Be sure you do

Page 5 SV Subwoofers More Setup, calibrating and integration If you are running a pair of SVS’s (Fig. 2), you will need to use a stan- dard “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 signal cable (d.) to each sub thus “splitting” the Low Frequency Effects (LFE) and other bass signals from your receiver, thus feeding both subwoofers.

We don’t mean “is your subwoofer ampli- fier on” (that’ll be important later too!) but rather, is your receiver sending a ? This can only happen if you say “Yes” (or bass signal to your sub amp “ON”) to the “subwoofer” setting of any typical Dolby Digital/DTS capable receiver. • Is your receiver connected to the sub amp? As discussed above, use a well-shield

SV Subwoofers Page 8 Phase. Think of bass waves as conflicting or enhancing each other, depending on the timing of their arrival at your listening location (either together, or not). Since some of your room’s bass might come from main, center and/or surround speakers, as well as your sub, getting these bass waves to arrive in a complementary, enhancing fashion is the diffi- cult job of the phase knob. Essentially, this control varies the timing of the bass waves coming from the sub. Th

SV Subwoofers Page 10 This disc allows the user to play 10Hz through 98Hz in one hertz increments allow- ing very good resolution over your measurements. Other good examples for test discs are Avia’s Guide to Home Theater and Digital Video Essentials. When meas- uring the room’s response use a minimum resolution of 5Hz. Figure 3 on the previ- ous page shows a theoretical illustration of a room’s response. Before you plot your results however, it’s important to note the Radio Shack sound

SV Subwoofers Page 11 The LEVEL control is the amount of attenuation on the signal located at the center frequency. MIN is equal to 0dB and MAX is equal to -12dB “cut”. Each hash mark reduces the Center Point in question by 1.5dB. The “FREQ” control (short for frequency) is the adjustment for the center point of the cut and should target the highest peak frequency in the room’s response. Each hash mark for this control moves the center frequency for the desired cut 5Hz within a rang

SV Subwoofers Page 12 Subsonic Filter and Port Tuning Your new PC-Ultra subwoofer not only comes with our “Tri-Power” port flares, but custom port plugs and variable subsonic filter which allow your sub to be “tuned” to even lower frequencies than its stock configuration. For most people and most rooms, your SVS is already configured for the best blend of extension (how deep/low your sub goes) and output (how loud it gets at a variety of bass frequencies). However, we know that b
