Introduction

The NuPrime MCX-800MZ is a multizone eight channels ampliﬁer that has four stereo modules, each with its own Adaptive Voltage Switching Power Supply technology and integrated ampliﬁer incorporating high-speed gate driver error correction. This technology enables each module to deliver explosive power and ultra-low distortion, with a neutral and detailed sound characteristic. The MCX-800MZ has advanced protection circuitry that safeguards it from fault conditions such as short circuits, overload, overtemperature, and under- voltage.

The Adaptive Voltage Switching Power Supply is the most innovative SMPS design introduced by NuPrime. The ampliﬁer’s output signal feeds back into the power supply’s servo power stage, causing a change in the output voltages supplying the power stage of the ampliﬁer. This design resulted in more details at a low music level and explosive power at a high volume.
