ABOUT EARTHQUAKE SOUND

For over 30 years, Earthquake Sound has been producing a variety of high- quality audio products that have impressed audiophile communities around the world. It all started in 1984 when Joseph Sahyoun, a music freak and Aerospace Engineer unhappy with the existing loudspeaker technology and performance, decided to put his advance engineering knowledge to use. He pushed technological boundaries to the limit to create the kind of subwoofer he could live with. Earthquake quickly createda name for it self in the car audio industry and became well known for its powerful subwoofers and amplifiers. In 1997, using his existing expertise in the audio industry, Joseph Sahyoun expanded his company to home audio production.
Earthquake Sound has since evolved into a leader in the home audio industry, producing not only subwoofers and amplifiers but surround speakers and tactile transducers as well. Engineered by audiophiles for audiophiles, Earthquake Sound audio products are meticulously crafted to reproduce each and every single note perfectly, bringing your home theater experience to life. With true dedication and full attention to details, Earthquake Sound engineers continuously develop new and better products to meet customers’ needs and go beyond their expectations.
From mobile audio to prosound and home audio, Earthquake Sound has been selected as the winner of many prestigious awards based on sound quality, performance, value and features. CEA and numerous publications have awarded Earthquake Sound with over a dozen design and engineering awards. Additionally, Earthquake Sound has been granted many design patents by the USPTO for revolutionary audio designs that have changed the sound of the audio industry.
Headquartered in a 60,000-square-foot facility in Hayward, California USA, Earthquake Sound currently exports to over 60 countries worldwide. In 2010, Earthquake Sound expanded its export operations by opening a European warehouse in Denmark. This accomplishment was recognized by the US Department of Commerce who honored Earthquake Sound with an Export Achievement award at the 2011 Consumer Electronic Show. Just recently, the US Department of Commerce presented Earthquake Sound with another Export Achievement award for expanding its export operations in China.

SYSTEM INSTALLATION CONSIDERATIONS
There are several factors to consider before installing or placing Earthquake Sound’s Supernova MKVI DSP Subwoofer.
What are the intended listening zones?
From where in each zone will the listener prefer to control the system? Where will the subwoofer be located?
Where will the source equipment be located?

CONNECTION TIPS

• Keep all power cords away from all signal cables to prevent humming from induced noise.
• Choose reliable signal cable cords (Earthquake Sound also specializes in high-performance RCA cables and patches).
• All speaker wires that are ran trough the walls should be twisted type to reduce potential hum noise pick-up.
• It is best to use a grounded electrical outlet to power the amplifier. Lack of input ground reference could be unsafe. Consult with your electrical contractor about proper grounding.

SAFE AND PROPER HANDLING
The Supernova MKVI DSP subwoofer is considerably heavy for an average person to carry or maneuver. To prevent injuries and eliminate any possible damage to the subwoofer, we encourage you to employ the help of a friend when unpacking the unit. We further suggest the following.

• wear a back support belt if needed when carrying/lifting the MKVI DSP 12P/15P.
• If possible, get someone to help you move your subwoofer.
• Do not apply pressure or push against the face of the speaker as this will cause irreparable damage to the cone and suspension.

SAFE AND PROPER HANDLING CONT’D

• When carrying your subwoofer, make sure that the speakers/grilles are positioned away from your chest, eliminating the chance of pushing against the face of the speaker.
• Do not drop the subwoofer or subject it to sudden shocks. This will damage the external finish and weaken the enclosure, creating air leaks.
• Avoid exposing the your subwoofer to moisture. Water will damage the wood structure as well as the amplifier and speaker.
• Cleaning your subwoofer is best using a soft cloth. If needed, use a mild detergent with water. Like any other electrical unit, always make sure that the unit is unplugged prior to cleaning it.

UNPACKING THE SUPERNOVA MKVI DSP

• Keep the original carton and packing materials for future shipment storage.
• Check for any visual signs of damage. If you encounter any concealed damage, consult your Earthquake Sound dealer before proceeding with unit installation.
• Retain the sales receipt as it establishes the duration of the limited warranty and provides information for insurance purposes.
  The Supernova MKVI DSP is packaged well for safety. We highly suggest having a padded surface and at least two (2) people to safely unpack the subwoofer.

STEP 1:
On a padded surface, carefully place the box on its side to remove the bottom packing tape and staples.

STEP 2:
Without tilting the box too much, tug the bottom flaps outward and keep the protective foam in place.

STEP 3:
Gently re-position the box upright.

STEP 4:
Slide the box off, minding the protective foam on the top, bottom, and sides of the subwoofer.

Congratulations and thank you for choosing the Earthquake Supernova MKVI DSP as a key component of your home audio system.
MKVI DSP subwoofers utilize an advanced digital class “D” amplifier, a premium long throw active driver and patented SLAPS v2 passive radiator technology. With a ported design and black piano gloss enclosure, Supernova MKVI DSP subwoofers deliver phenomenal bass. Pairing the MKVI DSP with the iWoofer™ mobile app allows for features such as automated room tuning adjustment for full control of the DSP and a more customized listening experience through mobile devices.
Designed in the U.S.A., The Supernova MKVI DSP series of subwoofers meet and exceed industry standards of performance and quality. With compromised “World Class” performance and superior technology, MKVI DSP subwoofers embody both power and elegance.

WHAT MAKES A SUPERNOVA MKVI DSP

Digital Class “D” Amplifier
The MKVI DSP amplifier utilizes an advanced class “D” circuitry with over 90%efficiency, allowing it to perform continuously without getting hot. This 1500 Watts peak power amplifier is fully equipped with IR inputs, auto room tuning adjustments, 0–180º phase switches, low-level RCA inputs & outputs, auto signal sensing, and iWoofer™ app-controlled DSP module.
Premium Long Throw Drivers
The active driver installed in every MKIV DSP 12P and 15P is specifically designed for accurate reproduction of bass and sub-bass frequencies. Built with TCT (Turbine Cooled Transducer) technology, stitched tensile leads, anti- wobble cone construction, and reinforced dust cap, the MKVI DSP active driver effortlessly produces phenomenal bass with extremely low distortion while staying cool.
Mass Tuned SLAPS (Symmetrically Loaded Audio Passive System)
Earthquake’s own patented SLAPS passive radiator technology dramatically increases the subwoofer’s efficiency and capability for ultra-low frequency reproduction. The unique design of the SLAPS employs dual (identical) suspensions, allowing the passive driver to move the same amount of air in either direction. Coupled with the active driver, the SLAPS enables the subwoofer to deliver louder bass without using more power from the amplifier.
Luxurious Piano Gloss Cabinet
The deep luxurious black piano lacquer begins with a thorough sanding and priming, followed by multiple applications of black lacquer with additional fine sanding between each layer and finished with a smooth, high gloss clear coat.

AMPLIFIER PLATE OVERVIEW

1. Low Level RCA Input
   Use this input to deliver an audio signal from your A/V source to the Supernova MKVI DSP amplifier.

2. Mono DSP Output
   Use this RCA output to deliver signal to an additional powered subwoofer or amplifier.

3. Balanced XLR Input
   Earthquake Sound highly recommends the use of a fully balanced XLR input ca- bles when the distance between a sub-woofer and the audio source is excessive and susceptible to any noise interfer-ence. The XLR input is a true balanced input and both conductors are isolated relative to ground.

4. Balanced XLR Output
   Use this output to deliver signal to an additional powered subwoofer or am- plifier that has an XLR input.

5. Auto/On/Off Mode Switch
   This is a 3-way switch. When ON, the amplifier will remain on regardless of signal presence. When set to AUTO, the amplifier will only turn on when audio signal is detected. Additionally, the am-plifier will go to sleep/standby if it does not detect any signal after 15 minutes. When set to OFF, the amplifier will remain off regardless of signal pres-ence. Note that the MAIN POWER switch must be in the ON position in order for this feature to work.

6. Input Selector Switch
   Use this switch to select between the input method that will be used to de- liver signal to the MKVI DSP amplifier.

7. Low Pass Filter
   This variable low pass filter from 40–160Hz is designed to control the subwoofer’s cutoff frequency. Any Signals above the set crossover frequency will gradually roll off to prevent from interfering with your surround speakers.

8. Phase Shift Switch
   This 0–180º switch allows the user to synchronize the subwoofer to obtain a better and more precise bass response.

9. DSP On/Off Switch
   This switch is used to enable or disable the application-controlled DSP. When set to the OFF position, the frequency adjustment knob (7) will be active allowing the user to make manual adjust-

ROOM TUNING WITH iWoofer™

Room Correction Control
The iWoofer™ Pro app features automatic room correction. To begin select “Room Correction” from the main menu. Once there, select “Wizard” to begin the automatic room correction process. Before beginning, ensure that the gain knob is properly adjusted on the woofer and that the sub is not over-driven.
The iWoofer™ Pro app will begin by taking a near field measurement. Place the microphone as close as possible to the subwoofer and equal distance from the passive side. This can best be done by placing the microphone so that it is facing the side of the subwoofer halfway between the active and passive. After placing your mobile device in the proper location, select “Next” to begin the sweep. It is important to remain as silent as possible during the sweeps. The subwoofer will begin sweeping through the frequency range. Once completed, you will be asked to add an additional response or sweep measurements or you may continue. Earthquake Sound recommends performing a minimum of 3 response sweeps in order to get an accurate measurement.
Once you have obtained the desired sweeps select “No, Next” to continue to the next step. You will be prompted to select either boomy region, near field, or linear room compensation. We rec-ommend the “Boomy Region” selection since it maintains the high energy peaks of the low frequencies while creating a linear response for the mid-range. The Near Field option is ideal for users with poor mic tolerance as it measures relative SPL and only compensates for the room reflection and not the woofer/box itself. The final reference, Linear, creates as flat as a response curve as possible throughout the frequency range.
After the desired option is selected, iWoofer™ will then instruct you to place the mic in your typical listening position. Once the mic is placed, click “Next”. The iWoofer™ Pro app will then proceed to sweep again. As before, it is recommend to perform at least 3 re-sponse sweeps. Click “No, Next” when you have concluded your response sweeps and iWoofer™ will proceed to make the necessary adjustments to your subwoofer’s response.

AC POWER INPUT WITH BUILT-IN FUSE
The AC line connector is fused to pro-tect the subwoofer from unwanted power surges. Be sure to use the proper fuse rating when replacing the fuse. To access the fuse compartment, simply unplug the subwoofer from any power source and place a flat-head screwdriver in the small notch and pry it open as illustrated below.
110-120V~60Hz:ø5x20mm, T6.3AL/250V
220-240V~50Hz:ø5x20mm, T3.15AL/250V.

PLACING YOUR SUBWOOFER(S)
You often hear the term “subwoofers are non-directional.” This is not true. It is harder to choose subwoofer placement when low frequencies are crossed. The wider the room, the more directional the subwoofer. The easiest solu-tion is to use two (2) subwoofers, feed a mono signal to both and place them in front, one on the left and another on the right.
While having two (2) subs is better than one, the MONO signal that drives those subs keeps them from projecting the three-dimensional images in the sub- harmonics. Using two (2) subwoofers allows you to cross the subs up to 250Hz sound quality, imaging and staging. In some applications, you might have small front speakers or planar speakers. The two front-subwoofer system is an excellent solution to planar speakers’ low-frequency response early roll off from 150Hz on down. When placing these subwoofers in close proximity to the stereo satellite, the subs will enhance low-frequency extension. It will be better to have a stereo sub-woofer to help in the lower bass notes and their placement.
Suppose you have only one (1) sub-woofer in the room and it is placed on the right side of the room. If a bass guitar player was standing on the left side of the stage and played a EE note (42Hz), then the sub will also respond to that from the right side of the room and completely destroy the stage.
You will see illustrations showing the two (2) different suggested setups. In each of them, note the breakaway and the image separation represented by the black and gray arrows.

The black arrows rep-resent the sub-har-monic frequencies and the gray arrows rep-resent the lows, mids,and highs as they follow the action. The best response is achieved when the sub-harmonic frequencies are dynamically synchronized with the rest of the audio system, the black and gray arrows are identical.

SINGLE SUBWOOFER SETUP
This is a GOOD setup. The subharmonic frequencies (black arrow) always move towards the sub in the single sub setup while the lows, mids, and highs (gray arrow) follow the action.

Placing the subwoofer in the corner of the room will produce a more boomy effect, often preferred for movies and sound tracks. For a music application, place the subwoofer as show above or against the front wall, about a third of the room width.

ROOM TUNING WITH iWoofer™

About iWoofer™
iWoofer ™ is a mobile based applica-tion developed by ARTEM KHLYUPIN, that allows the user to control DSP set-tings from a mobile device. In addition to full DSP control, the iWoofer ™ Pro app offers automatic room correction to achieve a more linear or boomy re-sponse from the woofer.

Getting Started
Launch the iWoofer™ or iWoofer™ Pro app on your mobile device. Ensure that the iWoofer supported subwoofer is powered on and that Bluetooth is en-abled on your mobile device. There is no need to search for the Bluetooth signal, the iWoofer™ app will automatically find it. Once the application has been launched, a list of devices found will ap-pear as shown in the image. The device name is generally a string of letters and numbers representing the unique MAC or UDID address of the woofer you are connecting to. Alternatively, the “Demo Mode” can be used to test the iWoofer™ features without connecting to a woofer.
After selecting your device, you will be prompted to import a DSP preset. If no previous presets have been saved on the woofer, select “Cancel” to continue connecting, otherwise select “OK”. Your mobile device will now connect with the woofer.Once connected, the device can be renamed from the “Options” menu.

BALANCED XLR SETUP – DUAL SUBS

The diagram below illustrates how to connect two MKVI DSP subwoofers using only balanced XLR cables. Use the MONO DSP output to connect one MKVI DSP to an additional MKVI DSP sub-woofer or any other sub that supports an XLR input.

PLACING YOUR SUBWOOFER(S)
DUAL SUB SETUP WITH MONO SIGNAL
This is a BETTER setup. In a dual sub-woofer setup, the sub-harmonic fre- quencies (black arrow) always move towards the middle of the room while the lows, mids, and highs follow the ac-tion (gray arrow).

Notice the breakaway and image separation is less in this setup than the single subwoofer setup.

CONNECTING THE MKVI DSP
LOW LEVEL SETUP – SINGLE SUB
This is the best way to drive an audio signal to your Supernova MKVI DSP subwoofer. Today, all signal processors (5.1, 6.1, etc.) come equipped with built-in pre-amplifier outputs (RCA) that in-clude a subwoofer output. Generally, the SUB PRE OUT is in a mono format. Connect the SUB PRE OUT from your audio/video processor to the MKVI DSP LOW-LEVEL INPUT using a “Y” RCA cable.
We strongly recommend that you use the best available RCA connectors and cables. High quality cables are normally triple shielded and the connectors are gold plated with forceful grasping.
When using this connection, the Super-nova MKVI DSP only receives bass sig- nals from the source. Therefore, the crossover frequency should be set at max value.

LOW LEVEL SETUP – DUAL SUBS
For a more realistic sound stage and greater theater experience, we suggest having two (2) subwoofers and running them in stereo.
Using a “Y” RCA cable, connect the SUB PRE OUT 1 of the receiver to the LOW LEVEL INPUT of the left side Supernova MKVI DSP amplifier.

Using another “Y” RCA cable, connect the SUB PRE OUT 1 of the receiver to the LOW LEVEL INPUT of the right side Supernova MKVI DSP amplifier.
In case the subwoofers become of out of phase with the main front speakers, flip the phase switches to correct the problem. Note that maximum bass is only achieved when the subwoofer is in phase with the rest of the speakers in your audio system.

BALANCED XLR SETUP – SINGLE SUB
If the distance between the MKVI DSP subwoofer and the audio source is ex- cessive and susceptible to noise inter-ference, use the fully balanced XLR input if your A/V receiver or processor supports an XLR output. This is a true balanced input and both conductors are isolated relative to ground.
