WELCOME

At SVS, you can actually hear the tireless research and design efforts built into our subwoofers and speak-

ers. Years are spent developing any SVS product. These days our teams work typically span from our Ohio

headquarters to all corners of the USA and of course with the ﬁnest component suppliers in Asia and Europe

as well. Nearly nothing in our speakers is an “off the shelf” part. We spend more and tend to overbuild our

stuff, because that’s how our customers like it.

SVS is committed to making better sound systems with elegant looks, robust construction, world-class tech-

nology and materials. We believe you deserve nothing less. This manual and the printed Quick Start sheet

will help integrate your speakers and subwoofer quickly and with professional results. Armed with only a few

basic tools, such a sound pressure level (SPL) meter, and the test tones built in to most audio/video receivers

(AVR), you will achieve smooth, detailed and powerful reproduction of all your favorite music and movie audio.

Expect to hear things you never heard before… and expect not to hear some of the artifacts you might have

accepted in the past from inferior brands.

Have a question about your surround sound system? For more information about SVS products check

out our US website, or speak with the exclusive dealer for your region. Regardless, contact us via phone or

email should you have questions about our products. SVS was founded by audio enthusiasts — our dedication

to customer service is the only thing rivaling the products we create.

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 com-

ponents 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. We range the world with our engineers and use the best stuff and best suppliers in the business.

Innovative designs, rich materials. We test all our materials and features in the real world and build

stuff our own in-house enthusiasts would buy with our own hard-earned money! “Over-built” SVS cabinet con-

struction ensures rigid cores for decades of solid performance. All our subwoofers offer computer controlled

panel cutting, steel fasteners recessed components, custom parts made just for us at every turn. Tap the side

of your sub, look at the solid construction, or remove your powder-coated grill. You’ll know what we mean.

Sealed, or vented; down-ﬁring or front-ﬁring cabinets. An SVS tradition. Offering 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, defeat-able crossovers, even power saving auto-on mode. Flex-

ible hookup options mean your SVS subwoofer can adapt to your space. Spend time exploring this guide and

contact your dealer if you require assistance on any feature.

World class driver power. SVS woofers have arguably been the industry’s best for a decade. Now our

advanced ampliﬁers raise the bar to new levels with digital signal processing (DSP) tuned pre-amps. With all

new power stages, more sophisticated protection our subs achieve exceptional depth, tremendous power and

ﬂat, natural sound that deﬁes price points or sometimes even words. To hear everything your favorite movies and

music have to offer you need the most reﬁned power available. SVS Sledge™ DSP amps push our exclusive woof-

ers like nothing else can.

Connectivity & Panel Operations

Operation of the Power Mode Switch

NOTE: Depending on the version of the STA-800D/STA-1000D ampliﬁer, the LCD display may or may not

light when power is ﬁrst applied. Even if the LCD display does not light when power is applied, if the

ampliﬁer is in the AUTO mode, it will play source material when a suitable signal is applied.

To manually come out of Standby when in AUTO mode, press and hold the IFC knob for several seconds

until the display lights. Note that menu operations are not possible when the ampliﬁer is in Standby.

In AUTO mode If power is removed from the ampliﬁer either through the main power rocker switch, or

by loss of power from the mains (wall outlet) and then restored, the ampliﬁer will either turn back on or

come up in Standby. If it comes up in the on state, it will revert to Standby after a period of time if no

signal is presented at the inputs.

When the AUTO/ON Switch is in the ON position and power is applied to the ampliﬁer via the main power

switch, the ampliﬁer will NOT turn on. In order to turn the ampliﬁer on, the IFC knob must be pressed and

held in for several seconds. When the ampliﬁer turns on, the LCD display will illuminate at the WELCOME

screen for a few seconds. The ampliﬁer will stay on until either the IFC knob is pressed and held until the

LCD display goes dark, when power is removed from the ampliﬁer using the main power switch, or power

is removed from the mains (wall outlet).

If power is removed from the ampliﬁer either through the main power switch or by loss of power from the

mains (wall outlet) and then restored, the ampliﬁer will not turn back on until the IFC knob is pressed and

held as noted above.

It is important to note in case of a power outage, it will be necessary to manually turn the ampliﬁer on

by pressing and holding the IFC knob as noted above. STA-800D and STA-1000D Connectivity and Panel

Connectivity & Panel Operations

STA-800D and STA-1000D Connectivity and Panel Operation

Inputs

There are two types of physical input connectors on the STA-800D/

STA1000D; Balanced XLR and single-ended (also referred to as low

level or line level). There are inputs for Left and Right main channels

for both types of connectors. There is also a switch below the input

connectors labeled “Input Level”. This switch can be used to select

either consumer audio (Normal)or pro audio (Hi-Level) voltage levels

depending on the source device.

The input signal(s) can have a High Pass filter applied which

affects the signal that appears on the STA-800D/STA-1000D’s

outputs. The input signal can also have a Delay applied independent

of the High Pass ﬁlter which can be used to add delay to the Left

and Right main speakers to accommodate preamps that have no

digital capability. See the next section that discusses the

Integrated Function Controller for a more detailed discussion

on using the High Pass ﬁlter and Delay functions.

Input Conﬁguration

Typically for most AVRs and pre/pros that have bass management

capability, connectivity to the STA-800D/STA-1000D would be via

FIG. 3

a single balanced or single-ended (RCA) connector from the Subwoofer Pre Out on the AVR or pre/pro to

either the Left or Right amp input (Fig. 4). This assumes the AVR or pre/pro does bass management for the

SAT speakers connected to it, handles the merging of any LFE (.1 channel in multi-chan-nel audio) content with

the bass from the SAT speakers, and manages the proper delay of all speakers and the subwoofer through a

distance or time delay function for each utilized audio channel.

Alternatively, for two-channel preamps that do not have (or do not use) any digital management, the typical

connectivity scenario would be to use both the main channel Left and Right inputs into the STA-800D/STA-

1000D (Fig. 5). In this case the subwoofer would sit between the main L/R outputs of the preamp and the L/R

inputs of the STA-800D/STA1000D, with the L/R outputs of the STA-800D/STA-1000D going to the inputs of the

power ampliﬁer for the system’s L/R main speakers. To then integrate the main speakers and the subwoofer,

the High Pass Filter, Low Pass Filter, and optionally the Delay feature of the STA-800D/STA-1000D amp would

be used. See the following section on the use of the Integrated Function Controller for more information on

using and setting these functions.

Power Mode Switch

The Power Mode switch allows the STA-800D/STA-1000D to either stay on all the time, or go into Standby

if no signal is being received. When in Standby mode and a signal is detected on one of the inputs, the

STA- 800D/STA-1000D will turn on and begin playing the material on its active input(s).

Outputs

There are two types of physical output connectors on the STA-800D/STA1000D; Balanced XLR and single-

ended with RCA connectors (also referred to as low level or line level). There are outputs for Left and Right

main channels for both types of connectors.

The output connectors are typically used to either daisy-chain additional subwoofers with single or dual unﬁltered

outputs, or as the input to a power ampliﬁer for the Left and Right main channels after using the High Pass Filter

and (optionally) Delay functions with two channel analog preamps (see discussion above under “Inputs”).

Main Power Switch

Use this switch to apply power to the STA-800D/STA-1000D ampliﬁer.

Power Cord

Plug the power cord into a wall outlet. Do not use extension cords to lengthen the cord. Do not plug into

accessory outlets on the back of an AVR or pre/pro.

Integrated Function Controller

This SVS Subwoofer is equipped with an advanced digital ampliﬁer, the SVS STA- 800D/STA-1000D Sledge™

DSP Ampliﬁer. The STA-800D/STA-1000D Sledge™ amp is not only digital for ampliﬁcation, but also for all

ampliﬁer control functions. Notice there is a single knob and a two line LCD display that allow you to set the

various Functions and their parameters of the SVS Subwoofer. This knob and the LCD screen are referred to

as the “Integrated Function Controller” or IFC for short.

The IFC replaces individual switches and knobs found on conventional subwoofer ampliﬁers. The straight-

forward menu structure and intuitive dialog makes setting up and maintaining the SVS sub much easier than

with past analog amps with a myriad of confusing and less accurate controls.

The IFC knob has three actions associated with it:

1. It can be turned both clockwise and counter-clockwise to either adjust a Function’s settings, or to

advance to a sub-menu within a Function.

2. It can be pushed in once (single-click) to select a (sub) function or to move forward and back- ward

within the IFC’s menu structure.

3. It can be pushed in twice in rapid succession (double-click) to quickly return to the top-level menu

structure.

The two line LCD display has two context modes:

1. Top-level menu screens.

2. Function/Sub-function screens.

The top-level menu screens allow the selection of major control Functions within the STA-800D/STA-1000D.

When power is ﬁrst applied to the subwoofer, the STA-800D/STA-1000D will display a WELCOME menu

showing the Model name of the subwoofer. If nothing is done for 30 seconds while in the WELCOME screen,

the LCD backlight will automatically go off. While in the top-level menu context, if nothing is done for 10

seconds, the display will revert back to the WELCOME screen.

High Pass Delay (STA-1000D)

The High Pass delay Function is a unique capability that allows the sound from the main speakers to be de-

layed. This feature allows users who have no means of time aligning their speakers and subwoofer through

their AVR or pre/pro (common with two channel analog systems) to add a delay-inducing component to their

subwoofer path such as a digital equalizer. The High Pass Delay affects the Output whether or not the High

Pass Filter in the STA-1000D is enabled or disabled.

In order for the High Pass Delay to function, the subwoofer must be placed between the output of the preamp/

processor and the input of the power ampliﬁer for the selected channel (front left or right) using either the

single-ended (RCA) or Balanced inputs and outputs on the STA-1000D.

From the IFC WELCOME screen, single-click the IFC knob and rotate the IFC knob four clicks clockwise until

the display reads “MENU/HIGHPASS DELAY”. Single-click the IFC knob to select the High Pass Delay Function.

Rotate the IFC knob clockwise or counter-clockwise to adjust the High Pass Delay value.

The range of adjustment of this control is 0 to 10 milliseconds in 1 millisecond increments.

Room Gain Comp

The Room Gain Comp (Compensation) Function allows the subwoofer to be set to compensate for the increase in low

frequency sound based upon the size of the room if it is felt there is too much bass. Small rooms will have a greater

increase in low frequency sound than larger rooms. There is no need to use this control unless it is felt there is too much

low frequency energy being generated in the listening environment.

This function operates by setting a corner frequency of 40Hz (small size rooms), 31Hz (medium size rooms), 25Hz (large

size rooms) or Disabled (no compensation), and allows a target slope of either 6 dB per octave (ﬁrst order) or 12 dB per

octave (second order) roll off from the selected corner frequency. This has the effect of attenuating the lower frequencies

below the selected corner frequency at a rate commensurate with the selected slope.

From the IFC WELCOME screen, single-click the IFC knob and rotate the IFC knob ﬁve clicks clockwise until the display

reads “MENU/ROOM GAIN COMP”. Single-click the IFC knob to get to the Room Gain Comp Function menu. If the Room

Gain Comp feature is disabled, a message to that effect will be displayed.

If the Room Gain Comp feature is disabled, turn the IFC knob which will display the Room Gain Comp submenu. To set the

IFC knob to return to the top-level menu.

Subwoofer Tune (Ported Subwoofers Only)

Note: This Function is active only in ported subwoofers and is inactive in sealed subwoofers.

The Subwoofer Tune Function allows the STA-800D/STA-1000D’s subsonic ﬁlter to be set based upon how the

ports have been blocked on a ported subwoofer.

From the IFC WELCOME screen, single-click the IFC knob and rotate the IFC knob six clicks clockwise until the

display reads “MENU/SUBWOOFER TUNE”. Single-click the IFC knob to select the Subwoofer Tune Function.

Rotate the IFC knob clockwise or counter-clockwise to adjust the Subwoofer Tune setting. Single-click to select

the desired tuning frequency. Single-click again to return to the top-level menu. If this function is selected ac-

cidentally, double-click to skip the function and return to the top-level menu.

The range of adjustment of this control is 20Hz (all ports open), 16Hz (one port blocked) or Sealed (all ports blocked).

P-EQ (Parametric EQualizer)

Note: Setting the Level of PEQ1 (STA-800D/STA-1000D) or PEQ2 (STA-1000D) to 0 effectively disables it.

The P-EQ Function allows room modes that exaggerate certain bass frequencies in a room to be reduced to by

up to 12 dB. Dips in frequency response can be boosted by up to 3 dB. The result of a reduction tames boomi-

ness and “one note bass” phenomenon that occur when a narrow range of bass frequencies are signiﬁcantly

louder than surrounding frequencies. Boosting a dip can bring forward frequencies that are masked by normal

levels around the dip.

The STA-800D has a single PEQ ﬁlter and the STA-1000D has two PEQ ﬁlters. PEQ1 and PEQ2 can be set in-

dependently from each other, allowing for more ﬂexibility in setting up the SVS subwoofer in any particular

listening environment. Both PEQ1 and PEQ2 operate identically.

Setup, Calibration & Integration

Before using your new subwoofer, it is important to get it set up and integrated into the rest of your audio or home

theater system to ensure optimum results. Failure to properly set up and calibrate your new subwoofer may result

in too much, too little, or boomy bass -- none of which provides the best overall listening experience.

There are multiple ways to set up and calibrate your subwoofer depending upon what type of equipment you have

and how many subwoofers you will be using. Each common scenario will be covered below, however if you have

questions about your speciﬁc situation that are not covered here, contact SVS Technical Support at techsupport@

svsound.com.

Unpacking and Subwoofer Location

If you have not already done so, take a few minutes to carefully unpack your new subwoofer. Try to avoid

damaging the shipping materials and keep the box and internal cushioning for a short time just in case you

need to return the sub for any reason.

There continues to be much discussion about subwoofer placement. If you have done your research and de-

termined the best place for your sub(s) in your room, that’s great. If not, we recommend starting in a corner,

especially in large rooms, leaving at least ﬁve to six inches in back for cable hookups and to access controls.

Corners provide the most reinforcement for both sub level and extension, and in most rooms provide good

response in most listening positions. However all the things that make a corner good can also work against

you in some cases, causing locations in the room where bass may sound overly loud compared to other loca-

tions or inversely, bass may be lacking the punch you expect. If you ﬁnd there is too much bass at certain fre-

quencies or bass response is uneven in the room, experiment with different placement options around the

room. There is surprisingly little difference between the front and the back of a room when the subwoofer

is properly calibrated so feel free to try any location that is convenient or meets aesthetic criteria for place-

ment in the room.

The STA-800D/STA-1000D ampliﬁer also offers room correction features to help with location and place-

ment. These include two single-band PEQs (PEQ1 and PEQ2), as well as a Room Compensation ﬁlter that

can attenuate overly loud bass caused by room gain. Refer to the section of this manual that discussed

the Integrated Function Control (IFC) for more information on these features. SVS also offers an advanced

digitalsubwoofer equalizer based on Audyssey MultEQ technology, the AS-EQ1. See the SVS web site for

moreinformation on this product if interested.

Setup, Calibration & Integration

Power and Signal Connection

Before making any power or signal connections, make sure all equipment in the chain is turned off. Plug

the subwoofer into a power outlet that is capable of a peak draw of 1100 watts. Using convenience outlets

located on some AVRs or pre/pros is NOT recommended for your subwoofer as these outlets are not meant

for high current devices.

For a discussion of the audio connections available on your subwoofer, see the section earlier in the manual

entitled “Connectivity and Panel Operation”.

From an audio signal connection perspective, there are two primary ways you can connect the subwoofer

based upon the capabilities of the AVR, pre/pro, or preamp you are using in your listening environment:

1) Bass Management and time alignment performed in the AVR or pre/pro. In this conﬁgura-

tion it is assumed that the subwoofer will be passed a signal intended strictly for the subwoofer – in other

words there is no additional higher-frequency information that needs to be accounted for.

Normally, you would use a single RCA (single-ended) or XLR (balanced) cable from your AVR or pre/pro’s

“Sub Pre Out” connector and attach it to either the Left or Right Input on the STA-800D/STA-1000D ampli-

ﬁer. If you have multiple subwoofers you can split the signal at the AVR or pre/pro using a “Y” adapter, or

you can daisy-chain an additional subwoofer through an Output connector on the STA-800D/STA-1000D

ampliﬁer with the HPF disabled if so equipped.

Using the Integrated Function Controller, set the following values as starting points for initial set up (facto-

rydefaults assuming no ports blocked if applicable):

2) Bass Management and (optionally) time alignment performed in subwoofer. In this con-

ﬁguration, it is assumed that due to the lack of bass management and time alignment capability in a preamp

(typical for 2 channel analog systems) these functions will be handled using the features of the STA-800D/

STA-1000D ampliﬁer.

If you are using one subwoofer for the bass of both Left and Right Channels, connect the Left and Right Pre-

amp Outputs for these channels to the corresponding Inputs of the STA-800D/STA-1000D, and the Outputs

of the STA-800D/STA-1000D to the Inputs of the power ampliﬁer for the main Left and Right speakers. If you

are using two subwoofers (one for each channel), connect the Left Output to one sub and the Right Output

to the second sub. Connect the sub Outputs to the respective inputs on the power ampliﬁer.

Using the Integrated Function Controller, set the following values as starting points for initial set up:

FIG. 10

Calibrating the Subwoofer

In order to get the best experience from your new SVS subwoofer, it is important to calibrate it with the rest

of your speakers. To do this correctly you either need an AVR or pre/pro with “Auto Setup” capability, or you

will need a Sound Pressure Level (SPL) Meter (preferably with Analog display) like those sold by Radio Shack

as well as a source of test tones.

It is highly unlikely the subwoofer level can be set correctly using hearing alone due to the difference in

hearingcapability of individuals, as well as the decreased level of hearing sensitivity in the lower frequen-

cies. There-fore it is highly discouraged to use your ears as a substitute for the SPL meter.

Setup, Calibration & Integration

If you have two or more subwoofers in your system, it is important that they be level-matched (set at the

same level relative to one another) before starting the calibration process. If the subs are not level-matched,

there is a risk of unbalanced bass and potential subwoofer localization in your listening environment. This

level-matching process is best performed using auto setup or a SPL meter as discussed above.

1) AVR or pre/pro with auto setup capability. Many AVRs and pre/pros newer than 2004 to

2005 have some form of auto setup capability that does a good job of setting channel levels and speaker

distances, making calibrating your subwoofer very easy. Review the documentation that came with your

AVR or pre/pro on how to run the auto setup feature and after connecting your subwoofer and setting the

initial values as shown above, run the auto setup routine.

At the completion of running the auto setup routine, there are two things you should check in your AVR or

pre/pro’s Manual Speaker Setup Menu to make sure your subwoofer has been integrated properly:

a) Check to see your speakers are all set to Small with a suggested crossover of no lower than 80 Hz. If

already Small and the crossover is higher than 80 Hz the setting should be left as is.

b) Check to make sure your subwoofer Trim value does not exceed the positive or negative limits of Trim

(typically +12 dB to -12 dB but may be different based upon your equipment). A value at the negative limit

(example, -12 dB) indicates the Volume on the subwoofer was set too high. Lower the Volume on the

subwoofer and re-run the auto setup routine. If the subwoofer trim is at the positive limit, raise the

Volume on the subwoofer and re-run the auto setup routine.

2) AVR or pre/pro without auto setup capability. Older AVRs or pre/pros may not have auto

setup capability. In that case, you will need a Sound Pressure Level (SPL) meter and a source of test tones

used to set speaker levels. SPL meters can be purchased at Radio Shack, usually for less than $50. Even

older multi-channel receivers and pre/pros have built in test tones but if yours doesn’t, calibration disks are

available that have the tones needed to accurately set speaker and subwoofer levels. SVS typically recom-

mends the AVIA II Guide to Home Theater by Ovation Software as a good calibration disk.

Before starting, familiarize yourself with your AVR or pre/pro’s setup and conﬁguration menu. Of particular

importance are the menus dealing with setting up your speakers (distance, level, size, crossover, etc.). Once

you have read and feel comfortable with setting up your speakers, you are ready to begin.

Start by making sure your AVR or pre/pro knows you have a subwoofer in your system. Sometimes the menu

item will be “Subwoofer = Yes, or “SUB ON”, etc. Ensure all speakers are set to Small and have

crossovers set no lower than 80 Hz (a speaker set to Small – as opposed to Large or Full Range – will cause

bass frequencies below the selected crossover to be routed from the speaker to the subwoofer).

a) Make sure you have a known good battery in the SPL meter (use the Battery Function). Set the “Weigh-

ing” switch to “C”, and the “Response” switch to “Slow”.

b) Set the “Range” dial to “70” to start. Consequently, when the meter displays “0”, that will indicate 70

dB. When the meter reads “5”, that will indicate 75 dB. When the meter reads “-3” (left of “0”), that will

indicate 67 dB.

c) In the AVR or pre/pro speaker setup menu, set the value of the subwoofer trim to -3 db. Set the Master

Volume (main volume control) of the AVR or pre/pro to 0.0 dB. In most units, this will produce a reading of

close to 75 dB on the SPL meter when playing the test tones on your speakers.

d) Place the SPL meter in your main listening position, ideally on a tripod (the Radio Shack SPL meter will

mount to a standard camera tripod adapter) with the unit pointed straight up (microphone pointed at the

ceiling). Adjust the tripod so the microphone is roughly at ear height.

e) Using the Manual Speaker Setup menu of your receiver or pre/pro, play the speaker level-matching test

tone and adjust each speaker to read 75 dB (“5” on the meter with the range switch set to 70) using the

speaker Trim controls found in the menu for each channel. When playing the test tone for the subwoofer,

use the VOLUME control on the STA-800D/STA-1000D to raise or lower the level of the subwoofer to read

75 dB leaving the subwoofer Trim control in the AVR or pre/pro set to -3 dB. (Note the meter may ﬂuctuate

by several dB when measuring the subwoofer. This is normal and what you are seeing are room modes in

play. Use the average of the swings to determine the volume of the subwoofer.)

If you have two subwoofers, you should ﬁrst set each sub to 75 dB with the other off, then split the differ-

ence between the two when making level adjustments with them both on. For example, if you need to lower

the level of the combined two subs by 4 dB, lower each sub by 2 dB.

f) From this point forward to add to or decrease the level of your subwoofer(s), use the subwoofer Trim in

your receiver. In some cases the level of your subwoofer Trim may exceed +/- 5 dB after tweaking your sub

level to taste. If this occurs, use your SPL meter and a combination of the subwoofer Trim in your AVR or pre/

pro and the VOLUME control on the STA-800D/STA-1000D to get the subwoofer Trim back to -3 dB while

reading your desired subwoofer level on the SPL meter.

Port Tuning

Advanced Features: Port Tuning (Ported Subwoofers Only)

Your new SVS ported subwoofer comes with custom foam port plugs and a variable subsonic ﬁlter which allows your sub

to be “tuned” to even lower frequencies than its stock conﬁguration. For most people and most rooms, the sub is already

conﬁgured for the best blend of extension (how deep and how low your sub goes) and output (how loud it will play). How-

ever, bass is a very personal and subjective taste, and no two rooms will react exactly the same with any subwoofer.

There are some compromises when tuning a sub lower than its standard conﬁguration. Installing one port plug takes

some capacity from the upper reaches of bass but will allow the subs to play at lower frequencies. Installing three port

plugs effectively conﬁgures your sub to a sealed conﬁguration, including the lower frequency roll off going from 24 dB per

octave (ported) to 12 dB per Octave (sealed). Again the tradeoff is output versus extension. Let your ears be your guide.

To insert one or three port plugs, ﬁrst remove the grill. The box sub grill is attached magnetically and will pull off easily.

The cylinder sub grill can be pried off using your ﬁngers or a small ﬂat blade screwdriver (gently!) around the edges of the

grill, slowly working it off around the entire perimeter. After the grill has been removed, take a port plug and squeeze the

foam on one end and press the plug into the port ﬂare. The plug should be recessed ¾” to 1” into the mouth of the port.

To remove a port plug, insert your ﬁngertips into the port ﬂare, squeezing and pulling on the foam plug at

the same time.

FIG. 11

To avoid potentially damaging your subwoofer, be sure to select the proper subsonic ﬁlter setting that coincides

with your new subwoofer’s tuning point. The subsonic ﬁlter is adjusted using the “Subwoofer Tune” function

accessible by using the Integrated Function Controller (IFC) on your STA-800D/STA-1000D Sledge™ ampliﬁer.

See the section above on how to use the IFC to change the value of the Subwoofer Tune.

NOTE: It is strongly recommended you do NOT run a lower subsonic ﬁlter point than your port plug conﬁgura-

tion would dictate. Failure to properly align Subwoofer Tune and port plug conﬁguration can potentially result

in serious damage to your subwoofer, especially if run at higher sound pressure levels.

Setup & Use of PEQ

Advanced Features: Parametric Equalizer (PEQ)

Important Note: Until you are ready to use the PEQ feature set, it should be disabled and setting the Level

in both PEQ1 and PEQ2 to 0. See the discussion above on the Integrated Function Controller for instructions

on how to Disable and set the PEQ Level, as well as selecting the Frequency and Q values.

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). The PEQ allows you to reduce

the severity of a peak in the subwoofer frequency response up to -12 dB, and to boost a dip in frequency

response up to + 3dB, thus obtaining a more accurate sound. The STA-800D/STA-1000D Sledge™ ampliﬁer

in your subwoofer contains two PEQ ﬁlters labeled PEQ1 and PEQ2 so you can implement one (STA-800D) or

two (STA-1000D) different sets of cut or boost.

Control Explanation: The PEQ has three controls: Frequency, Bandwidth, and Level.

The Frequency control (labeled “FREQ:” ) selects the center frequency where the PEQ cut will take effect,

and has several discrete frequencies to choose from. These include: 31, 35, 40, 46, 50, 56, 63, 70, 80, 90,

100, 112 and 125 Hz.

The Bandwidth control (labeled “Q:”) affects the width of the PEQ cut or boost. The higher the Q value, the

narrower the bandwidth of the cut/boost and conversely, the lower the Q value the wider the bandwidth

of the cut or boost. In most cases, it is best to start with a high Q setting (narrow bandwidth) and widen out

(lower Q) as the results are observed. To better understand the relationship between Q values and octave

bandwidth, browse the following link:

http://www.sengpielaudio.com/calculator-bandwidth.htm

The following table summarizes bandwidth of the Q settings in the STA-800D/STA-1000D Sledge™ ampliﬁer:

Cuts of up to -12 dB and boost of up to +3 dB are allowed.

Setup & Use of PEQ

Measuring 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 a spreadsheet, or it can be accomplished using

software such as “TrueRTA”, or “Room EQ Wizard (REW)”. 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. An active user forum for REW exists on the Home Theater Shack web site, http://www.homethe-

atershack.com/forums/rew-forum/

To measure the subwoofer FR using a manual method, you will need a SPL meter, a basic working knowl-

edge of Microsoft Excel (or other spreadsheet program), and a means to generate sine wave test tones.

There are several sources of sine waves and/or tone generators on the internet. A popular tone generator is

the NCH Tone Generator ( http://www.nch.com.au/tonegen/index.html ) which is available for time-limited

trial use, and may also be purchased for a nominal fee. You can download working Excel spreadsheets

from the SVSound web site at:

http://www.svsound.com/techsupport/Subwoofer_Frequency_Response.xlsx

and

http://www.svsound.com/techsupport/Speaker_And_Subwoofer_Combined_Frequency_Response.xlsx

Place the SPL meter on a tripod and set the controls to C-weighted, Slow, and the 70 dB scale (you may need

to alter the dB scale during the measurement process). Place the meter at head level at the primary listening

position with the meter pointed toward the ceiling at a 90 degree angle.

To set the overall test level, play a 25 Hz frequency and adjust the subwoofer Volume (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.

Setup & Use of PEQ

Option 1: Measure the FR of Subwoofer Only Using Excel Spreadsheet:

To measure the FR of the subwoofer only, connect your sound card output directly to a line level input on

the subwoofer. Use the Excel spreadsheet named Subwoofer_Frequency_Response (link provided above),

which will plot the frequency response of the subwoofer from 11.2 Hz to 100.8 Hz. Input your raw (direct

read) values from your SPL meter into the green band of frequencies in the Raw SPL Data worksheet, and

the Frequency Response worksheet will plot the FR of the subwoofer.

Below is an example of a subwoofer FR. Notice the large peak from 35 - 55 Hz.

FIG. 14

To correct a peak such as that above, start by setting the Frequency to 40 Hz, the Q to 14.4, and the Level to

-10 dB. Re-measure and re-plot from 30-70 Hz to evaluate the effect.

Option 2: Measure the Combined FR of the Speakers and Subwoofer using Excel Spreadsheet:

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. Use the Excel spread-

sheet named Speaker_And_Subwoofer_Combined_Frequency_Response (link provided above), which will

plot the frequency response from 11.2 Hz to 201.6 Hz. Input your raw (direct read) values from your SPL

meter into the green band of frequencies in the Raw SPL Data worksheet, and the Frequency Response

worksheet will plot the combined FR of the speakers and subwoofer.

Adjusting The PEQ: Identify the largest/widest peak in the response and target it for reduction with

the PEQ control. When making adjustments to the PEQ control, there is no need to re-plot the entire FR for

interim adjustments - simply re-plot the affected section of the curve to verify your PEQ adjustments are

having the desired effect. When you are done making adjustments, you can re-plot the entire frequency

response to obtain a ﬁnal curve.

plot 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. The Frequency and Cut effect look cor-

rect, but the Q is too narrow. Adjust the Q to 9.6 and try again.

Room Compensation

Advanced Features: Room Compensation

In typical home theaters a phenomenon known as “room gain” can play a major role in how accurately

bass is produced.

When any subwoofer produces notable bass energy below 40Hz, the output you will perceive is different

than the sub’s normal output would be (if unaffected by your room’s walls).

The difference in actual bass, versus theoretical (quasi-anechoic/anechoic) bass response, can be thought

of as rising SPL levels in the room as frequency decreases. The smaller the room, the more room gain comes

into play – e.g. louder levels as frequency decreases as compared to larger spaces where the effect is less

noticeable. Room gain can create excessive deep bass which can sound exaggerated simply due to interac-

tion with your room.

If you ﬁnd your bass is excessive and lowering the level of the subwoofer using the subwoofer trim in your

AVR or pre/pro does not have the desired effect, you should try using the Room Compensation control in

your STA-1000D ampliﬁer. To enable and adjust your Room Compensation control, see the section earlier in

this manual on the Integrated Function Controller (IFC).

Use the table below as a guide to select the appropriate Room Compensation corner frequency for your

speciﬁc listening environment.

FIG. 17

To rapidly roll off the lower frequencies below the selected corner frequency, select -12 dB per octave slope.

For a more gradual roll off, select -6 dB per octave slope. For example if the corner frequency selected is

40Hz, the subwoofer output level would be down 12 dB at 20Hz if -12 dB was selected, or down 6 dB at

20Hz if -6 dB was selected.
