Page 4 SV Sound Chapter 3 SV Subwoofers Welcome! At SVS, you can actually hear the tireless research and design efforts built in to our subwoofers and speakers. Years are spent developing any SVS product — with work typically spanning from our Ohio headquarters… to US west coast technology centers… and over to the finest component suppliers in Asia and Europe as well. Nothing in our speaker offerings is an “off the shelf” product.
SV SV Subwoofers Sound Chapter 4 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. You could have spent much more on other brands and still not come close to the performance our products provide. What makes a subwoofer an SVS? Quality components, sane prices.
Chapter 5-1 SV Sound Powered Box/Cylinder Common Features: 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 Receiver (AVR) subwoofer output level control) to achieve bass level calibration to your liking. Start your setup with the sub’s volume/gain no more than 1/4 to 1/3 of the way up (turned clockwise from the left). Crossover Frequency.
Chapter 5.2 SV Sound 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 to recalibrate channels levels with your sound meter afterwards). Crossover Feature Switches.
SV SV Subwoofers Sound Chapter 6-1 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. Location. Where you put a sub is important to how it will sound. Use a corner if you can, and avoid putting your sub where it might adjoin large open areas.
SV SV Sound Sound Chapter 6-2 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.) From the “Y” cable you can run a standard 75 Ohm RCA signal cable (e.) to each sub, thus “splitting” the Low Frequency Effects (LFE) and other bass from your receiver, and effectively feeding both subwoofers with the same signal.
Chapter 6-3 SV Sound Also, is your subwoofer turned “ON”? We don’t mean “is your subwoofer amplifier on?” but rather, is your AVR sending a bass signal to your sub amp? This can only happen if you say “Yes” (or “ON”) in the “Subwoofer” selection during the setup of your AVR’s setup menu. Is your receiver connected to the sub amp? Use a well-shielded “RCA” cable (sometimes called a “patch cord”) to connect the subwoofer output of your AVR to either input jack of your subwoofer’s dedicated amp.
SV Sound Page 6-4 11 Chapter Page 11 But what’s “too high”?? Tastes vary, and do movie soundtracks, but your SVS subwoofer is capable of tremendous levels of low distortion, low frequency 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” channel (LFE) bass action, and give the sub a bit extra gain during calibration. Keep in mind too that the human ear is relatively insensitive to low frequencies.
Chapter 7-1 SV Sound Advanced Features: Subsonic Filter and Port Tuning Your new SVS subwoofer comes with custom foam port plugs and variable subsonic filter which allows your sub to be “tuned” to even lower frequencies than its stock configuration. For most people and most rooms, your sub is already configured for the best blend of extension (how deep/low your sub goes) and output (how loud it gets).
Chapter 8-1 SV Sound Advanced Features: Parametric Equalizer (PEQ). Important Note: Until you are ready to use the PEQ feature set, it should be disabled by setting all three controls to the full counter clock-wise position. Background Information: Direct and reflected bass waves in the listening room will create “standing waves” and associated peaks and nulls in the subwoofer frequency response (FR).
Chapter 8-2 SV Sound “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 listening positions. This can be done manually using test tones and an spreadsheet, or it can be accomplished using software such as “TrueRTA”, or “Room EQ Wizard”. SVS does not provide technical support on the setup and use of any software, but it can make measuring the subwoofer FR easier and faster than manual methods.
Chapter 8-3 SV Sound To set the overall test level, play a 25 Hz frequency and adjust the subwoofer gain (option 1 below) or the processor master volume (option 2 below) until the SPL meter reads about 75 dB at the listening position. Run each tone only long enough to get a stable reading from the meter (about 5-6 seconds), and then give the subwoofer about 10 seconds to cool off between test frequencies.
Chapter 8-4 SV Sound Option 2: Measure the Combined FR of the Speakers and Subwoofer: To measure the combined FR of the front speakers and subwoofer (to include 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 subwoofer.
Chapter 8-5 SV Sound 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 replot the affected portion of the FR curve and visually evaluate your results. Simple trial/error will then allow you to adjust all three controls to shape the PEQ cut to achieve the desired effect. The previous image shows the results of the first PEQ cut attempt.
