MCX Multi-channel Amplifier

A new level of audio realism

We designed the MCX amplifiers specifically for people who are looking for the "best of both worlds" performance, between audiophile stereo music listening and explosive movie soundtracks. "Handcrafted" class A transistor circuit replaces off-the-shelf OpAmp for precise and natural sound signature.

Whether you're listening to music, playing a movie, live concert or video games, the MCX amplifier with its lightning fast dynamics and ultra-low distortion brings you to a new level of audio realism.

Taking the best bits from NuPrime's award winning products, the MCX has been developed for the multi-channel market. We understand that it is not only power that enthrals the listener, but also the accuracy of reproduction to create a realistic experience.

The MCX utilizes NuPrime’s Class A+D hybrid amplification technologies deliver the substance and warmth of Class A amplification and the efficiency and speed of Class D technology in a milieu of un-measurable noise. A 1000W power supply and 33,000 uF CMA capacitor array allows the MCX to fully exploit the Class A+D design’s ability to deliver massive amounts of power and speed when needed by a single or multi channels.

By utilizing discrete components in NuPrime’s ULCAM circuit, the signal can be fine tuned to reduce noise and provide maximum power. The MCX amp circuit improves on traditional class-D design by using a self-oscillating circuit to generate pulse-width modulation. The amplifier switches at a frequency of 550kHz, well beyond the compact disc’s 44.1kHz sampling rate.

Power Rating & Measurement

• For typical usage of multi-channel amps, the situation where all channels are driven at max power will never happen.

• The MCX amps are designed to handle a wide range of speaker impedance from 2 Ohms to greater than 16 Ohms.

• As the speaker load varies and drop, the power increases (normally a 4 ohm load would have twice the power).  But for high power amplifier the 4 ohm power rating can not exceed power supply, amplifier design limit and safety standard. Many manufacturers would claim theoretical (max) power to hype up the product spec.

MCX amplifiers are the successor to acclaimed NuPrime MCH-K38 with further sonic refinement, increased power, reduced noise and heat.
