Thank you for choosing Earthquake Sound’s line of MiNi D amplifiers, the best way to
enhance your factory mobile audio system. With proper installation and responsible
listening, your amplifier(s) will give you years of near perfect sound reproduction.
WWe strongly recommend you to have your new amplifier(s) installed by an authorized
Earthquake Sound dealer. Installation professionals employed by your dealer have the
correct tools and knowledge to install your amplifier(s) neatly and successfully. Also,
when your new products are installed by an authorized dealer, your products will
include a ONE (1) YEAR LIMITED WARRANTY. If you choose to perform your own
installation, your warranty will be subject to further limitations. Dealer policies on
handling warranty requests may vary from one dealer to the next.
Please
Please read the warranty information (located at the end of this booklet) in its entirety
and use good judgment when making these vital decisions.
CAUTION: Earthquake amplifiers are capable of generating high sound pressure levels. You
should exercise caution when operating these amplifier systems. Long term exposures to high levels of
sound pressure will cause permanent damage to your hearing. Sound pressure levels exceeding 85dB
can be dangerous with constant exposure. Set your audio system to a comfortable loudness
level. Earthquake Sound Corporation does not assume liability for damages resulting from the direct use
of Earthquake amplifiers or other Earthquake products and urges users to play their music at moderate
listening levels.

not in the signal path, but works by sensing the electromagnetic field of the conducting
wires. Like OMEGA , the internal communication of MARS is optical rather than
electrical. MARS does not use any relays or other damping-factor reducing mechanical
switches that can wear out or fail over time. Instead, a specially designed circuit
instantly shuts off the output drive. In the event a short-circuit activates the MARS
protection system, it continuously re-scans the output every 10 seconds. Normal
operation automatically resumes as soon as the short-circuit condition is removed.
MARS (Magnetically Actuated Reanimation
System) is a new type of protection system that
enables the use of all amplifier power
resources without compromising the survival of
the amplifier under catastrophic conditions.
Typical protection systems rely on fuses or
relays that complicate the signal path thus
degrading audio qualitdegrading audio quality. MARS is different as it is
OMEGA is tapped into every circuit and transmits instructions in the optical plane with
a speed of 500khz, making it deadly accurate. This enables constant optimization of
power generation and amplification. The best example of efficiency gain due to
OMEGA is the power supply and amplification section, previously operating without
coordination. With OMEGA they operate in continued adaptive synchronization, almost
doubling their output. In addition to adaptive synchronization OMEGA utilizes an
optical multilevel feedback path operating in the digital domain - providing real time
targeting
targeting data, enabling OMEGA to digitally steer voltage and current with absolute
precision.
OMEGA (Optical Multilevel Empirically
Guided Aggregation) is the highly evolved
brain and central nervous system of the MiniD
amplifier. Traditional amplifiers are comprised of
many circuits, operating in blind autonomy.
OMEGA adds intelligence and operational
awareness to these functionsn - transforming
autonomy into unit
autonomy into unity.
The MiNi-D3000.4 is essentially two Mini-D1500.2 amplifiers fused together in one
chassis, resulting in the most power-dense 4 channel amplifier on the market today.
With 180 watts RMS to each of its 4 channels, the MiNi-D3000.4 D has enough power
to satisfy even the hungriest speakers all while remaining incredibly composed. The
audiophile attributes are so refined that a panel of audio experts could not pick it out
against esoteric home audio amplifiers.
It was clear that the amplifiers of the future would be smaller, stronger and smarter.
However breaking through the technical barriers on the way would require
considerable innovation. To decrease the size of an amplifier its necessary to increase
efficiency. This requires intelligence and control. In the pursuit of these goals several
new technologies were developed.
Mini-D is a true next-gen amplifier - with features and a level of
design sophistication years beyond the competition. With the
Mini-D, Earthquake once again reasserts absolute dominance
in the field of car amplifier technology.
TTo decisively leapfrog the car amplifier industry, would be no
easy task. Earthquake’s chief engineer, Joseph Sahyoun,
descended into the Earthquake research laboratories
determined to crack the code to the universe and design the
car amplifier of the future!
Smaller - Stronger - Smarter

A critical area for efficiency in a Class D amplifier is the speed and precision by which
the transistors can be opened and closed. VE-TAT dramatically increases transistor
velocity, thus eliminating dead-time losses and increasing efficiency. The addition of
VE-TAT makes the Earthquake Gen 3 Enhanced Class D output topology the most
efficient Class D technology on the planet today.
VE-TAT (Velocity Enhancing Transistor
Augmentative Technology ) is an enhanced
transistor dead-time controller. Where OMEGA
is a macro overlay system - VE-TAT works at the
component level.
Real-World Benefits
TheThe real world benefits of these technologies are significant. In comparison to a
traditional Class AB amplifier with an efficiency of 45 percent, the MiniD at 96 percent
will use less than half the power playing at the same volume. Or it will play 3 db louder
with the same amount of power. 3 DB is the same as adding an extra woofer to the
system. With MiniD even a staunch system will be able to operate with just the stock
battery and alternator. As MiniD is very competitively priced against inferior rivals - all
this extra power is basically FREE.
Reclaim your trunk space! The new micro form-factor of the MiniD opens up a new
realm of placement possibilities - Under car seats, inside door or chassis panels. It is
no longer necessary to stuff your trunk with amplifiers to get great sound.
Unprecedented Placement Possibilities
FEATURES
• Clip Suppression Technology. The Mini-D will avoid hard clipping , so in the event
of excessive input the sound will not get harsh.
• Fan free operation. The stellar efficiency of the MiniD negates the need for noisy
fans. Even when driven continuously 2 db into clip the MiniD will not overheat.
•• Variable Subsonic filter option to protect speakers from unwanted low frequency
content.
• Auto ON signal sensing switch. Amplifier can wake up on signal and fall asleep
when not in use.
• RCA line outputs for daisy chaining multiple amplifiers.
• User selectable high & low pass crossovers with variable crossover frequency.
•• MARS status LED. Lights up when MARS has detected an anomaly and when the
unit is initially powered up and going through self analyzing mode.

When the switch is on AUTO ON, the amplifier will auto-
matically detect an incoming signal when the stereo is
turned on. If the amplifier does not detect any signal after
20 minutes, the amplifier will automatically turn off.
In case the system goes into protection, simply turn off the
audio source and slide the switch to RESET then back to
AUTO ON position.
When the switch is on REMOTE ON, the amplifier relies
on the remote wire to detect the signal and turn the ampli-
fier on or off.
The proper power and remote wire connection when using the Auto Signal Sensing is
illustrated below.
(!) DO NOT connect the remote wire to the battery wire as this will make the amplifier’s
auto sensing feature not work properly.
(!) DO NOT connect the remote wire to the head unit as this will damage your sound
system.
NOTE: RCA outputs must be inserted in CH1/2 for the amplifier to detect any incoming
signal.
