- Page 5 SV Subwoofers SV Sound About your SVS Subwoofer There maybe be other subwoofers that look like them, but virtually none work like them. SVS subwoofers are decidedly different in how they are designed, produced, sold, and the exceptionally high quality components we use.
- Page 6 SV Sound Chapter 5-1 Powered Box/Cylinder Common Fea- tures: SVS subwoofer amps use the most durable and accurate designs possible. Get familiar with yours! Volume/Gain Use “gain” (in conjunction with your Audio Video Re- ceiver (AVR) subwoofer output level control) to achieve bass level calibration to your liking.
- Page 7 SV Sound Chapter 5.2 Sometimes, with very low listening levels, your subwoofer might not get enough of a bass signal from your AVR to “trip” the Auto-On circuit. Should you ever find this to be the case you may leave this switch to “On”, or turn up the AVR’s subwoofer level some (be sure...
- Page 8 SV Subwoofers SV Sound Setup, calibrating and integration What’s to know? Setup is easy! However, there are key steps which must be done carefully and correctly, read on: Unpacking. Take a few moments to carefully unpack everything. Save the box and shipping materials, just in case you need to return the sub for any reason.
- Page 9 SV Sound SV Sound More Setup, calibrating and integration If you are running a pair of SVS subwoofers (Fig. 2), you will need to use an inexpensive “Y” cable adapter (d.) dard 75 Ohm RCA signal cable (e.) to each sub, thus “splitting” the Low Fre- quency Effects (LFE) and other bass from your receiver, and effectively feed- ing both subwoofers with the same signal.

- Page 11 Page 11 Page 11 SV Sound Chapter 6-4 But what’s “too high”?? Tastes vary, and do movie soundtracks, but your SVS subwoofer is capable of tremendous levels of low distortion, low fre- quency bass — far more than most subs in this size or price class. Take advantage of this, especially if you like action movies with lots of “.1”...

- Page 15 SV Sound Chapter 8-2 “Q” Control Effects Measuring The In-Room Frequency Response: In order to use the PEQ effectively, you must measure the in-room FR of the subwoofer at the lis- tening positions. This can be done manually using test tones and an spreadsheet, or it can be accomplished using software such as “TrueRTA”,...
- Page 16 SV Sound Chapter 8-3 To set the overall test level, play a 25 Hz frequency and adjust the sub- woofer gain (option 1 below) or the processor master volume (option 2 below) until the SPL meter reads about 75 dB at the listening position.
- Page 17 SV Sound Chapter 8-4 Option 2: Measure the Combined FR of the Speakers and Subwoofer: To measure the combined FR of the front speakers and subwoofer (to in- clude the digital crossover in your processor), connect your sound card output to an analog input on your processor. Make sure the analog input is configured to use the digital crossover between the speakers and the sub- woofer.
- Page 18 SV Sound Chapter 8-5 Set the Frequency control to the approximate center frequency of the largest peak. Set the Q control to HI (narrowest bandwidth), and set the Level control to MAX. Play the test tones again and re-measure and re- plot the affected portion of the FR curve and visually evaluate your re- sults.
