Smaller - Stronger - Smarter
MiniD is a true next-gen amplifier - with features and a level of design sophistication years beyond the competition.
With MiniD, Earthquake once again reasserts absolute dominance in the field of car amplifier technology.
To 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! 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.
Unprecedented placement possibilities.
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.
Real world benefits
The 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.
OMEGA
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 functions- transforming autonomy into unity.
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 data, – enabling OMEGA to digitally steer voltage and current with absolute precision.
VE-TAT
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. 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.
MARS
MARS – (Magnetically Actuated Reanimation System) is a new type of protection system that enables the use of all amplifier power resources without compromising the survivability of the amplifier under catastrophic conditions. Typical protection systems rely on fuses or relays that complicate the signal path thus degrading audio quality. MARS is different as it is not in the signal path, but works by sensing the electromagnetic field of the conducting wires.
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.
