The Model 302 takes Jeff Rowland's vision into the future with the implementation of Jeff's proprietary digital switching power circuitry. Dubbed MECC (Multivariable Enhanced Cascade Control), this circuit is neither class D nor any other existing classification, simply the fruits of Jeff's meditations on circuit design and an expanding inventory of innovative digital hardware. Thanks to the MECC circuit, the Model 302 is far more electrically efficient than its predecessors. While Jeff has moved back to the Model 8 chassis design for the Model 302, the overall dimensions have been reduced, as has the weight. The weight savings are made possible by the reduction of the large capacitors featured in Jeff's past designs. The chassis has also undergone extensive structural redesign, yielding the most rigid resonant-free structure Jeff has ever designed.
