When you have safely removed the amplifier 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.Thecustomized packaging isspecially designed toprotecttheamplifier frompotential damage thatcan arise when shipping such aproduct.  
To reduce the risk of fire or electric shock, do not expose this product to rain or moisture. Don not attempt to “lift the ground” by removing  
WARNING!  
the ground pin from the AC cable. Make sure that your household electrical wiring supports proper AC 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  
extremetemperature. Always connect theaudio signal pathcable prior toconnecting theACmains.

Subwoofer Placement Guide  
GOOD / This illustration shows a single subwoofer setup  
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 Note  
the breakaway and the image separation. Best  
response if the blue and the red are identical  
Why having two gains on a mono subwoofer is  
agoodthing?  
Often you hear the term “subwoofers are non-directional”;  
this is not true subwoofer placement is harder to pick when to  
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 planer speakers. Both  
speakers have an early roll off in the sub-harmonics. The  
planer needs help from 150Hz on down, having two front  
subwoofers placed on the left and the right is a health  
solution tothisproblem.  
BETTER / This illustration shows dual subwoofer with mono signal  
TwoSubs  
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, Note the breakaway and the image  
separation  
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 sub up to 150 Hz sound quality, imaging and staging. The  
two-front-subwoofer-system is an excellent solution to planer  
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 extention. It  
will be better to have a stereo subwoofer to help in the lower  
bassnotesand their placement.  
BEST / This illustration shows dual subwoofers with stereo+mono signals  
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.  
In this illustration the stereo subwoofers keep the  
sub-harmonics dynamically synchronized in  
motion with the rest of the audio systems. Fully  
complementary sub-harmonics to the mids and the  
highs

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.
