MiNi D1000.4 2nd Gen (Open-Box)

MiNi D1000.4 2nd Gen

As the first 4-channel full-range amplifier of the MiNi D series, the MiNi D1000.4 2nd Gen is blazing its own trail. It does so by cramming 4 full channels of robust cool running power into a micro chassis the size of a portable hard drive. This level of power density is just now possible thanks to the new Power Chip technology from Earthquake.

Power Chip Technology

The next frontier, in the race to make the smallest and most powerful amplifiers, is Power Chips. A Power Chip is a chip like a computer processor that has all the functions of a normal discrete component output stage. Earthquake is at the forefront of this battle with the introduction of the Hybrid Power Chip amplification technology featured in the MiNi D1000.4 amplifier. It combines the output Power Chip itself with a wideband discrete switch mode power supply connected through an intelligent communications bridge. This best of both worlds solution has Power Chip compactness and discrete transistor resiliency.

VE-TAT Enhanced Power Supply

Velocity Enhancing Transistor Augmentative Technology is an enhanced transistor dead-time controller. VE-TAT is a component level technology. A critical area for efficiency 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 SR-SMPS switch mode power supply one of the most efficient on the planet today.

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.

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.
