When you have safely removed the subwoofer from the packaging and placed it in a safe area, perform a thorough physical inspection and report any damage to the  
dealer that you purchased the unit from. We suggest that you keep the original packaging, and that it should be stored in a safe, dry place in case you’re required to  
transport the unit.The customized packaging is specially designed toprotect the amplifier from potential damage that can arise when shipping such a product.  
To reduce the risk of fire or electric shock, do not expose this product to rain or moisture. Do not attempt to “lift the ground” by removing the  
WARNING!  
ground pin from theAC cable. Make sure that your household electrical wiring supports properAC grounding techniques before plugging  
in this product. Keep the heat sinks and top cover free of dust to allow for proper heat dissipation. Never expose this product to extreme  
temperature. Always connect the audio signal path cable prior toconnecting theAC mains.  
No user-serviceable parts inside. Do not attempt to remove cover or repair this product, as severe electrical shock may result and it may  
disrupt your warranty.  
CAUTION!  
Make sure that your localAC voltage complies with the unit’s label. Damage caused by plugging this subwoofer into anAC receptacle of  
the wrong voltage will not be covered by warranty.

Subwoofer Placement Guide  
GOOD / This illustration shows a single subwoofer setup  
Why having two gains on a mono subwoofer is  
a good thing?  
The blue arrow represents the subharmonic  
frequencies as they move always toward the sub in  
the single sub system. The red arrow represents  
the lows + mids + highs as they follow the action.  
Often you hear the term “subwoofers are non-directional”;  
this is not true. Subwoofer placement is harder to pick when  
two low frequencies are crossed. The wider the room, the  
more directional the subwoofer. The easiest solution is to use  
two subwoofers in the front: one on the left and a second on  
the right. The signal to both is mono. In some applications,  
users might have small front speakers or planar speakers.  
Both speakers have an early roll off in the sub-harmonics.  
The planar needs help from 150Hz on down, having two front  
subwoofers placed on the left and the right is a healthy  
solution tothis problem.  
Note: The breakaway and the image separation.  
best response when blue and the red are identical.  
BETTER / This illustration shows dual subwoofer with mono signal  
Two Subs  
The blue arrow represents the sub-harmonic  
frequencies as they move always toward the  
middle in a mono-two-subs- system. The red arrow  
represent the lows+ the mids+ highs as they follow  
the action,  
While having two subwoofers is better than one, the MONO  
signal that drives these subwoofer keeps them from  
projecting the three dimensional images in the sub-  
harmonics. The use of two subwoofers allows you to cross  
the subs up to 150Hz sound quality, imaging and staging.  
The two-front-subwoofer-system is an excellent solution to  
planar speaker’s low frequency response early roll off. When  
locating these subwoofers in a close proximity to the stereo  
satellite, the subs will enhance low frequency extension. It  
will be better to have a stereo subwoofer to help in the lower  
bass notes and their placement.  
Note: the breakaway and the image separation.  
If a bass Guitar player was standing on the left side of the  
stage and he played an EE note (42Hz), then the right sub will  
also respond to that and create havoc on the stage. In fact, if  
you only have one single sub in the room and it’s placed on  
the right side of the room, while the bass guitar player is  
playing his music on the left side of the stage. As soon as he  
hits the EE note, the sub speaks out on the right and  
completely destroys the stage. To give you three-  
dimensional front-end bass that allows you to have a low  
frequency dynamic stage, Earthquake designed dual input  
circuits that use buffers to maintain your stereo separation on  
the processor side while mixing stereo front signals to  
produce 3D bass.

sub-harmonics dynamically synchronized in

Usually one RCA has enough signal to  
drive the IQ amplifier to its full output.  
However, in some cases where signal is  
too low for the IQ amp to produce its full  
output, you may use a " Y" connector to  
increase the amp's sensitivity.

Room Correction  
The MKVIs' amplifier offers a room correction technique that surpasses all previous  
attempts. The intelligent “Back emf” drive circuit interacts with the subwoofer design  
and memorizes system tuning frequencies as well as system type. The information,  
which is stored in microprocessor, turns on a preset group delay curve that serves as a  
correction reference. This information deals only with time correction that moves the  
peaks and the dips in a room to a flat. Once that is achieved, the user will resort to the  
final correction- EQ the room. For that reason, Earthquake’s SuperNova MKVI is truly  
an intelligent system. 20Hz, 30Hz and 40Hz frequencies can be cut or boosted by a  
whopping 6dB, these corrections help in producing wider range of listening position  
that is unprecedented forthe room.  
To begin the process of room correction, you should have two people: One  
person will make adjustments at the amplifier and the other at the meter.  
When setting the room EQ, do not over power the speakers. As this  
may cause them to bottom out or cause other more severe problems  
that your warranty will not cover. To set up the room EQ, you will need  
a spectrum-analyzer, or you can use the rule of thumb.  
STEP 1: Place your subwoofer in the most desirable area.  
STEP 2: Have the second person sit on a chair or sofa with a testing  
microphone or SPL meter.  
STEP 3: Load "white Noise" CD or 50Hz tone continuous.  
STEP 4: With the amp phase at 0° and the delay set at 0°, measure the SPL.  
STEP 5: Rotate variable delay until the dB measurement peaks (you will know  
that it has peaked when the measurement begins to go back down). Rotate the  
knob back to the peak section.  
STEP 6: Measure angle of rotation in approximate degrees.  
STEP 7: Reset all adjustments to zero(0) / Flip phase switch to 180°  
and redo test.  
STEP 8: Your best setting is when the phase is at 180° and there is less delay.
