CONNECTING & CONTROLLING YOUR DEVICE

The SVS PC-4000 is designed for easy set-up and integration in both multi-channel home theater and two-channel (stereo) systems. It is best to familiarize yourself with the subwoofer connections and the rear panel of your AV receiver or preamplifier before setting your subwoofer up. Be sure your PC-4000 is switched to Off before plugging it in or connecting to your AV receiver. It's also best to use cables with secure connections for optimal bass performance.

In addition to the IR Remote Control and front panel control interface, we've developed the convenient SVS mobile app for both Apple iOS and Google Android that allows you to make adjustments for room layout, personal preferences, movies vs. music, and more. It's the best way to fine tune your subwoofer for perfect performance from the comfort of your favorite seat.

A full explanation of all the advanced subwoofer DSP controls is available in following sections in this owner's manual, as well as in the SVS subwoofer app tutorial. The following sections cover basic connections and control settings when integrating the PC-4000 into a surround sound or two channel system.

BACK PANEL FEATURES

AC Power Connection

Connect the subwoofer power cord to the subwoofer amplifier and directly into an AC outlet. Convenience outlets located on the rear panel of some AV receivers or pre/pros are NOT recommended for your PC-4000 as these outlets are not meant for high power devices.

Line Level Connection

Single LFE Channel

The most common way to connect your PC-4000 is with a single RCA or XLR interconnect cable going from the LFE or SUB1 Output on your AV receiver or preamplifier to the LFE Input on your PC-4000. This allows your processor to perform the upstream bass management and send the subwoofer a pre-filtered mono signal.

Stereo Receiver or Preamplifier Left/Right Channels

Both Left and Right inputs on your PC-4000 can be used in a two-channel stereo application with a stereo preamplifier that has Left and Right line level or Balanced (XLR) outputs.
Connect the left and right outputs of your preamplifier to the left and right line level inputs of the PC-4000 using RCA or XLR interconnects.
Enable and adjust the on-board low pass filter of the PC-4000 for a smooth blend with the main speakers.

NOTE: For additional guidance on speaker/subwoofer crossover settings, please consult our Sound Experts or our Merlin subwoofer matching tool at www.svsound.com/merlin.

3V-12V Trigger Input

This feature will automatically turn the subwoofer on/off when a signal is sent to the trigger input from another component in the system (typically the pre/pro or AV receiver). The other component in the system must be equipped with a trigger output feature and requires a TS 1/8" mono cable (pictured below).

Connecting Multiple Devices

"Going Dual"
Running two or more subwoofers has many acoustic benefits such as: improved frequency response throughout the listening area, fewer peaks and nulls, increased output and decreased bass localization. The RCA and XLR Outputs provide an easy way to integrate multiple PC-4000s or other subwoofers into your audio system.

Many AV Receivers and Surround Processors have more than one subwoofer output.
As described previously, you can run a single connection from each subwoofer output to each of your subwoofers.

If you have more subwoofers than Sub Outputs from your AV Receiver, an easy solution is to use an RCA splitter or RCA Y-adapter to divide the subwoofer output. This is the most commonly recommended way to connect multiple subwoofers when there is only one Sub Out.

Another option is to use the Left and Right RCA or XLR outputs on the PC-4000 to Daisy Chain additional subwoofers. It's important to use the matching output and input terminals. For example, if you are using the RCA inputs, be sure to use the RCA outputs to daisy chain to the next subwoofer.

NOTE: While the settings of each subwoofer should be similar, you will probably find that each sub will need to be calibrated for optimal performance because of its unique room placement. Regardless of how you use your subwoofer, experimentation can often result in better sound. Don't be afraid to try different settings, you can always return the controls to their defaults.

In a 2-channel system you can set up Stereo Subwoofers, where one is used for the Left Channel and one for the Right Channel. Typically, the subwoofers will be symmetrically placed according to your speakers. And be sure to maintain all the correct Left and Right output and input connections to ensure optimum performance.

Control Settings for AV Receiver & Processor

If using your PC-4000 subwoofer with an AV Receiver or preamp with bass management, it is recommended to leave all control settings in the default position, aside from the volume, which allows you to adjust the level of output based on your personal preferences. Set the PC-4000 volume to -10 before running auto-set-up in the AV receiver/processor.

NOTE: Always re-run AV Receiver auto-set-up after moving the subwoofer to a different location to ensure the acoustic distance and calibration levels are set correctly.

NOTE: If you want to run the subwoofer louder than the initial auto-set-up level, adjust the subwoofer channel level upward in the AV receiver menu until you get the experience and performance you want. An increase of 2-4 dB louder than initial set-up level is common for many customers. Volume can be controlled from your mobile device via the Free SVS App, from the IR Remote Control, or using the buttons on the front panel interface.

Please consult the Advanced Subwoofer Controls section of this owner's manual or contact our SVS Sound Experts if you have questions about any of the control settings.

Control Settings for Stereo Receiver or Pre-Amplifier

Most Stereo Receivers and Pre-Amplifiers do not have bass management. Instead you will use the Left and Right full-range outputs and make adjustments through the DSP amplifier on the subwoofer.

Be sure to connect both Left and Right outputs to the Left and Right inputs on the subwoofer.
Set the Low Pass Filter to "On" and adjust the Crossover Frequency and Slope to achieve a smooth blend and transition with the main speakers.
Once blended, adjust the Subwoofer volume to match the volume level of your main speakers.

For finer tuning, our Merlin Subwoofer Selection Tool provides the recommended low pass filter frequency and slope setting for most loudspeakers on the market. Just choose your brand and model of speakers from the menus and Merlin does the rest. It's available 24/7, 365 at www.svsound.com/merlin. Our SVS Sound Experts are also standing by to help with any connection or control questions you have about any of the controls or settings.

NOTE: Volume and low pass filter can be controlled from your mobile device via the Free SVS App, from the IR Remote Control, or using the buttons on the front panel interface.

PLACING THE UNIT IN A ROOM

Placement of subwoofers is a process driven by competing variables that differ in every home. Décor, floor space, furniture, speaker placement, seating location, and of course, sound quality all factor into the decision of where a subwoofer should be placed. If you have flexibility, there's an artistry to subwoofer placement that can be aided by understanding some basic acoustic principles and set-up techniques.

If you are limited to a single subwoofer location, it's best to find the ideal listening location in the room. You'll notice as you move through the room, bass response will vary significantly. This is due to the complex pattern of standing sound waves in the room. Sometimes simply moving a few feet in any given direction can improve the balance and accuracy dramatically. Once you find the 'subwoofer sweet spot' in the room – reserve that seat for yourself!

Corner Placement

Corner placement of a subwoofer reduces the potential to encounter nulls, which are acoustic cancellation points or 'dead spots' in the room. While this can often make for hugely impactful bass, it can sometimes result in a "boomy" sound depending on your listening position. If you experience this, you can use the tuning controls to blend your PC-4000 more smoothly with your speakers or try pulling it further away from the walls to smooth out the bass response.

Front Placement

Front of the room placement in between or just to the side of the front channel speakers is another common choice. Front of the room placement usually results in the best blending with the main speakers and center channel and minimizes localization effects.

Side Wall Placement

Side wall placement is less frequently used but can be an effective subwoofer location for excellent accuracy and output.

Dual Unit Placement

Based on our own extensive testing, and research done by the professional audio community, we recommend the following placement options for dual subwoofers:

• Opposite diagonal front/rear corners.
  
• At the mid-points of the side walls.
  
• Front stage in the corners.
  
• Front stage flanking the center channel to the inside of the main speakers.
  

While the first two options are proven performers with typically excellent results, they are often difficult to implement in a living/family room environment. All rooms are different, so we recommend staying flexible and trying all possible placement options for the best results.

DEVICE CONTROL OPTIONS

Your SVS PC-4000 Subwoofer can be controlled from the new SVS Mobile App, an included IR Remote Control or via the front panel for unprecedented flexibility when optimizing performance for room layout, speakers, system set-up and more.

SVS Bluetooth App

Our groundbreaking SVS Subwoofer DSP app is available for free via the Apple App Store and Google Play Store. Just search "SVS App" and follow the prompts to download to your mobile device. Once installed, there's a helpful tutorial that will guide you through each option and provide common settings to simplify the process. The SVS App is the only way to access all of the advanced control features available on your PC-4000 and it is the most convenient option for controlling every feature.

IR Remote Control

The included IR remote can be used to adjust nearly every one of the advanced subwoofer control settings with two-way feedback on the front panel display.

Front Unit Panel

The front panel features an intuitive user interface with simplified controls that can be used to adjust the majority of the advanced subwoofer control settings.

ADVANCED DEVICE CONTROLS

Volume

Setting the level too high will cause the bass to seem bloated and is the single most common cause of bad sounding subwoofers. A rule of thumb is that the subwoofer should not draw attention to itself, but should simply make the systems low end seem more extended and accurate. Different content has different levels of output so adjust volume based on source material and your personal preference.

Low Pass Filter

Enables smooth sonic transition and flat frequency response between speakers and the subwoofer. This allows you to control the upper frequency cut-off to blend with main speakers. It also allows you to adjust slope, or the rate at which the low pass filter rolls off. If using an AV Receiver with a Subwoofer Output, leave in the OFF position.

Phase Adjustment

Solves sound wave cancellation issues at specific frequencies and perfectly aligns the arrival of output from speakers and subwoofers to your listening position. Normally set to 0° if the subwoofer is near the main speakers. Adjusting Phase shifts timing of the subwoofer output to align with the main speakers or additional subwoofers.

Polarity

In some cases, reversing polarity solves dips or humps at the crossover frequency between a subwoofer and speaker and can be used to fix bass nulls or overly boomy spots in the listening area. Reversing the electrical polarity of the subwoofer amplifier makes it so the woofer moves in when speaker drivers move out and is normally set to positive

Parametric EQ

Powerful tool for removing peaks and dips in your listening area, and for creating custom subwoofer output based on personal listening preferences. Works best when used with acoustic measurements.
Allows you to set the desired center frequency of the filter, increase or decrease the SPL dB of the filter, or adjust the bandwidth of the filter.

Room Gain Compensation

Fixes bloated sounding bass by optimizing low frequency output and extension when too much sound wave density is being created by a small room.

CONNECTING & CONTROLLING YOUR UNIT

Presets

Allows up to three pre-saved settings for movie, music and custom. This enables easy switching to optimize your PC-4000s output and settings based on your specific listening preferences with different kinds of content. If using the SVS App, these presets can be renamed as desired.

Port Tuning

Port blocking allows custom tuning of your PC-4000 Subwoofer based on listening preference by exchanging max output for low frequency depth and quickness. Foam port plugs are available upon request by emailing custservice@svsound.com. When using the feature, always match port blocking with the selected tuning via the SVS Subwoofer App.

Three tunings are available:
Standard Tune = All ports open (highest maximum output)
Extended tune = One port plugged (deeper extension, slightly less maximum output)
Sealed tune = All ports plugged (best transient response)
