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. You might be surprised at how
inexpensive the components in some not-so-inexpensive subwoofers
are. At SVS, performance is king... not cutting a few dollars from our
“cost to build”.
Innovative designs, rich materials. We test all our materials, and
features in the real world, and test size and shape, before any design is
deemed ready. Cabinet construction must ensure rigid and durable
products. All our subwoofers offer computer controlled panel cutting,
steel fasteners, and recessed components. Tap the side of your sub,
look at the solid construction or remove your grill, and you’ll know what
we mean.
Sealed, or vented, down-firing or front-firing cabinets. An SVS
tradition is to offer a variety of “form factors” which provide exceptional
performance yet also a compact “foot print” which complements your
room style.
Features and controls. Variable phase, crossovers which can be
defeated, and on select models, variable tuning, equalizers or other
advanced controls are built in to allow customers to make their SVS fit
their needs. Spend time exploring this guide and contact your dealer if
you require assistance on any feature.
World class power. Our advanced amplifiers are designed and
manufactured with a level of fit and finish, and genuine power which is
rare at our competitive prices. Loaded with comprehensive of easy to
use controls, and our tremendously efficient Ohio-built woofers, all our
subs achieve exceptional depth, tremendous power and flat, natural
sound. Hear everything on your music CD’s and DVD’s with SVS
products.

Powered Box Basic 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).
Phase. Think of long bass waves as conflicting or enhancing each other,
depending on the timing of their arrival at your listening location (either
together, or not). Set phase to zero if your AVR offers settings for the
distance from your seat to your subwoofer. Adjust in small steps for
smooth sound with music playing if your AVR lacks a subwoofer distance
setting.
Line In/Out. Use the sub’s “Line In” jack (RCA) to connect the subwoofer
to the output jack of your AVR. A simple RCA signal cable is all you need
for either type configuration. .
Auto-On. Your Powered Box allows itself to be in an “Auto-On” mode…
or “On” all the time. With the former setting (the switch in the “Auto” posi-
tion) your subwoofer will “sense” that a DVD or CD etc. has begun and
switch its audio circuits on immediately (the “hard” power switch men-
tioned below must be set to “on”, naturally). A few minutes after a movie,
the Auto-On light will turn from Green to Red, switching portions of the
sub’s power supply back off.
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 chan-
nels levels with your sound meter afterwards).
Power. This heavy-duty two-position switch next to the power cord will
completely cut the power to your sub amp. Flip this switch to off before
you ever move the sub or change inputs or outputs. Do not plug this sub
into receiver convenience power outlets. Allow five minutes of “off” time
before switching back “on”.
Fuse. User replaceable, contact your dealer if you have trouble finding
one. The fuse can be accessed by a small door immediately next to the
power cord fitting (where you should also find a spare one for your use).

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. Studies have shown that the deepest and flattest bass
response is typically attained when a subwoofer is placed within a few
feet of one of your room’s corners (leave about 3” in the back for cable
clearance with any wall or other surface). Whether you put the sub in
front or to the rear of your room makes surprisingly little difference.
Hook-up (see Fig. 1). There are a variety of ways to configure your new
sub. Usually, a simple mono, shielded 75 Ohm A/V RCA type cable (a.)
is used to take the subwoofer output of your AVR (b.) and feed the low-
level input of the sub’s amp (c.).
NOTE: Take time to review
your AVR manual. Ensure all
power to your equipment is off
when making these connec-
tions. Also, be certain your power outlet
can handle a minimum of 400 watts. (Use
of “convenience outlets” on receivers are
not recommended for your sub).

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 stan-
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 (when phase is properly adjusted,
achieving a significant 6dB of added “headroom” versus only one sub). .
NOTES: Determine if you want
“ON” (always on) or “AUTO ON”
which turns your sub on only when
a bass signal is present. High
power amp designs can require five minutes
of “OFF” time before sub will resume “ON”
status again.

“Calibration” isn’t only for technically minded sound enthusiasts. It is ’s criti-
cal to a proper configuration of your home audio system. Fortunately, adjust-
ing channel balance (essentially all “calibration” amounts to) is simple to do.
The first requirement is to ensure your AVR is ready. Thus we recommend
you consult your AVR manual to review the choices you have regarding
setup. Generally, this requires your receiver’s test tones play back at the
same volume from each of your system’s speakers. Of course this can in-
clude speakers at left, center, right, left surround and right surround plus the
subwoofer itself.
Some things to check as you get ready to calibrate:
Are your speakers set correct to the correct “size”? Your
AVR should allow you to your speakers be set to “Small” or
“Large”. Selecting the size accordingly will ensure bass goes to
most appropriate speakers, and use the subwoofer correctly too.
“Small” is nearly always the best configuration with a good sub-
woofer and all but the largest speakers.

Also, is your subwoofer turned “ON”? We don’t mean “is your sub-
woofer amplifier on?” but rather, is your AVR sending a bass sig-
nal 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 the RCA input on the subwoofer’s amp. Again, you’ll
need to “split” the bass signal with a “Y Cable” if you have a pair of subs.
Is your Radio Shack ® sound pressure level (SPL) meter ready?
This tool is absolutely essential to proper home audio
setup. It’s akin to a tire pressure gauge for your car. Set
the meter to “Slow” and “C-weighting” (and turn the dial to
70dB. If using Avia for calibration tones, set your meter to
80dB instead.)
Getting ready to start now: Make sure your receiver or proc-
essor’s master volume is set to “00 dB” or some other easy to
remember “reference level”. Then, ensure your sub’s volume/
gain control is set no more than 1/4 to 1/3rd up, for now, leaving
plenty of adjustment “up”.
It’s also critical to check the subwoofer output level control of your AVR before
you begin the test tones. Set the AVR’s subwoofer output to about 1/3rd up too.
Turn off any sound-field processing schemes, “Mid-night Mode”, “DRC” (dynamic
range control), “Movie Mode” etc. If it is an option in your system, route your
LFE to the “subwoofer only”, not “mains + sub”.
Now play your AVR’s internal test noise “tones” so you have something to
measure with your SPL meter. When the tones start alternating from speaker
to speaker (watch your sound meter now), set each speaker’s volume to about
75 dB by using the receiver’s dedicated channel level controls (leaving your
AVR’s master volume the same).
We recommend you turn down the AVR’s subwoofer channel output level before
you significantly lower your subwoofer’s gain control. This helps keep distortion
sent to your SVS to a minimum. Note: You should not set the AVR’s subwoofer
level control much lower than the first 1/4th of the receiver’s control range.
Some downward adjustment may be needed to fine tune levels later. If your
subwoofer’s SPL meter reading is still too high, then turn down the sub’s amp
volume a little with each run of the test noise signal, as it cycles from speaker to
speaker and the subwoofer.

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” 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.
This, coupled with the fact most folks don’t watch movies at full “theater lev-
els” means raising the bass up a few decibels (dBs) usually yields a more
satisfying movie and music experience.
What bass levels do we recommend? If you watch movies at moderate
sound levels, a good start is a range of +1dB to +3dB above your other
channels (as measured with your sound meter). This means the test tone
will waiver about 78 dB for the subwoofer portion of the calibration run using
your receiver test tones.
Note too that many modern A/V receivers allow a variety of subwoofer level
settings, depending on the “listening mode” you are in. With “Dolby Digital”
as your “mode” use the above calibration routine. You may well find that CD
“Stereo” music calls for a lower bass settings. The above is a guide… ex-
periment! The louder your master AVR volume however, the more you
should reduce the subwoofer’s playback level to compensate. You should
always avoid your driver “bottoming”, resulting in a loud “clack”!
Location and measurement. You should take the above measurements
from your typical preferred seat for watching movies. Be advised, strong
bass levels can vary tremendously simply by moving your seat, or your sub-
woofer, just a short distance. Such is the nature of long wavelength, deep
bass sound. Do not hesitate to try different locations and different levels for
your subwoofer.
Setting playback levels on the sub which are too high (and often, too low) is
the most common theater/music setup error.
