version 1.0.07142020 SUBWOOFER CONNECTING & CONTROLLING YOUR SUBWOOFER The SVS 3000 In-Wall 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 3000 In-Wall is switched to O before plugging it in or connecting to your AV receiver. Its also best to use cables with secure connections for optimal bass performance. The convenient SVS mobile app for both Apple iOS and Google Android allows you to make adjustments for room layout, personal preferences, movies vs. music, and more. Its the best way to fine tune your subwoofer for perfect performance from the comfort of your favorite seat. In addition to the SVS mobile app you can control the primary features of the amp using the Intelligent Control Interface (ICI) back-lit user interface on the amplifier plate. A full explanation of all the advanced subwoofer DSP controls is available in this manual, as well as in the SVS subwoofer app tutorial. The following sections cover basic connections and control settings when integrating the 3000 In-Wall into a surround sound or two channel system. BACK PANEL FEATURES 2 3 4 5 6

Convenience outlets located on the rear panel of some AV receivers or pre/pros are NOT recom-

mended for your 3000 In-Wall as these outlets are not meant for high power devices. Line Level Connection Single LFE Channel The most common way to connect your 3000 In-Wall is with a single RCA interconnect cable going from the LFE or SUB1 Output on your AV receiver or preamplifier to the LFE Input on your 3000 In-Wall. This allows your processor to perform the upstream bass management and send the subwoofer a pre-filtered mono signal. RECEIVER/PREAMP LINE LEVEL OUTPUTS LFE Rear Panel Graphic Line Level Connection Stereo Receiver or Preamplifier Left/Right Channels Both Left and Right inputs on your 3000 In-Wall can be used in a two-channel stereo application with a stereo preamplifier that has Left and Right line level outputs. Connect the left and right outputs of your preamplifier to the left and right line level inputs of the 3000 In-Wall using RCA interconnects. 3000 In-Wall SUBWOOFER CONNECTING & CONTROLLING YOUR SUBWOOFER Line Level Connection Stereo Receiver or Preamplifier Left/Right Channels (contd) RECEIVER/PREAMP LINE LEVEL OUTPUTS REAR FRONT AUTO PASS 30Hz 0 40Hz 60Hz 90Hz 140Hz Rear Panel Graphic 90 VOL PHASE LFE LOW PASS 180 PHASE Enable and adjust the on-board low pass filter of the 3000 In-Wall for a smooth blend with the main speakers.

Set-up is simple and quick and separate instructions are included with the adapter. NOTE: The 3000 In-Wall amplifier should be turned o when making all connections. Rear Panel Graphic 3000 In-Wall SUBWOOFER CONNECTING & CONTROLLING YOUR SUBWOOFER Control Settings for AV Receiver & Processor If using your 3000 In-Wall 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. NOTE: Always re-run AV Receiver auto-set-up after moving the subwoofer to a dierent 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 or using the buttons on the rear panel interface. Please consult the Advanced Subwoofer Controls section of this owners manual or contact our SVS Sound Experts if you have questions about any of the control settings. www.svsound.com custservice@svsound.com (877) 626-5623 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, the SVS Subwoofer Matching Tool on our website 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. Its available 24/7, 365 at https://www.svsound.com/pages/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, or using the buttons on the rear panel interface. 3000 In-Wall SUBWOOFER SUBWOOFER INSTALLATION INTRO COPY FOR In-Wall Subwoofer Placement Retro Fit with Dogs Retro Fit with stud screws

((REAR PANEL GRAPHIC)) 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 3000 In-Wall more smoothly with your speakers or try pulling it further away from the walls to smooth out the bass response. 3000 In-Wall SUBWOOFER Front Placement SUBWOOFER INSTALLATION 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 eects. Side Wall Placement Side wall placement is less frequently used but can be an eective subwoofer location for excellent accuracy and output. 3000 In-Wall SUBWOOFER SUBWOOFER INSTALLATION Dual Subwoofer 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 dicult to implement in a living/family room environment. All rooms are dierent, so we recom-

mend staying flexible and trying all possible placement options for the best results. 3000 In-Wall SUBWOOFER SUBWOOFER CONTROL OPTIONS Your SVS 3000 In-Wall Subwoofer can be controlled from the SVS Mobile App or via the rear panel for unprecedented flexibility when optimizing performance for room layout, speakers, system set-up and more. SVS Subwoofer App Our groundbreaking SVS Subwoofer DSP app is available for free via the Apple App Store, Google Play Store and Amazon Appstore. Just search SVS App and follow the prompts to download to your mobile device. Once installed, theres a helpful tutorial that will guide you through each option and provide common settings to simplify the process. The SVS App operates via Bluetooth and is the only way to access all of the advanced control features available on your 3000 In-Wall. It is the most convenient option for controlling every feature.

The subwoofer should sound like its naturally adding bass for all the speakers without overly drawing attention to itself. Dierent content has dierent levels of output so its normal to adjust volume based on source material and your personal listening preferences. 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-o to blend with main speakers. It also allows you to adjust slope, or the rate at which the low pass filter rolls o. 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 (SVS App Only) 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 (SVS App Only) 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 (SVS App Only) Fixes bloated sounding bass by optimizing low frequency output and extension when too much sound wave density is being created by a small room. Presets (SVS App Only) Allows up to three pre-saved settings for movie, music and custom. This enables easy switching to optimize your 3000 In-Walls output and settings based on your specific listening preferences with dierent kinds of content. If using the SVS App, these presets can be renamed as desired. 3000 In-Wall SUBWOOFER ADVANCED SUBWOOFER CONTROLS System Settings (SVS App Only) Allows you to make further customizations and reset your subwoofer to factory settings.
