Bel Canto BLACK ASC1/ MPS1 Ultimate Amplification System

The Ultimate Amplification System

Black is like no other audio system in the world. It communicates the musical experience completely, staying true to the recorded event and conveying the passion the artist intended. Achieving this level of detailed playback required rethinking the way signal travels through the many stages of the electronics system. This was the challenge behind Black and the reason we took a different approach, designing a 3 chassis integrated hybrid system.

Beautifully constructed from solid high grade billet aluminium, the modern look and feel of Black connects to all sources offering the highest level of flexibility and ease of use. Black creates an authentically present and naturally dimensional musical experience that will captivate you.

The System

Our integrated hybrid approach has 2 distinct functions. First, the ASC1 (Asynchronous System Controller) isolates noise and sends a pure optical digital audio signal to each MPS1 mono block without loss or degradation. Second, each MPS1 receives the digital signal from the ASC1, re-clocks the data, converts the signal to analog (Mono DAC) and amplifies the signal (Mono Amplifier).

There are many unique advantages to the Black system architecture. Critical to its performance is the proximity of the DAC to the amplifier, set only 3cm apart and isolated within the MPS1. This eliminates the need for added I/O circuitry, preserves signal accuracy and creates a more synergistic system. BLACK is a radical approach to integration, combining the best analog, digital, optical and mechanical elements to achieve the best playback possible.


ASC1 - Asynchronous Stream Controller

The ASC1 is the heart of the BLACK system. The ASC1 is not a digital to analog converter; it is a Master Clock/Controller and the only one of its kind. It could be described as the digital preamplifier, with analog and digital inputs and digital output. The easy to read programmable display allows you to select the best view or turn it completely off. 

The volume control and input selector is controlled from the multi-function rotating wheel on the top of the ASC1, you can also use the IR custom remote control, or your iPhone/iPad and the custom iOS app. The master control is always ready to adjust volume, press it once and rotate to enter input, or press and hold to enter the menu, where you can set the system up that best meets your needs.


MPS1 - Mono PowerStream

The MPS1 is a unique monoblock design with Ultra low noise Clocking, Digital to Analog conversion, Bel Canto's class A amplifier stages, and custom 1200 Watt Power Buffer in an optimized environment. 

The digital signal from the ASC1 is asynchronously re-timed before conversion in the advanced segment fully balanced mono DAC, that combines the best of Multi-Bit and delta sigma technologies measuring below 0.0005% distortion and 130dB of dynamic range. The high current output from the DAC is coupled directly into the I/V stage and within 3 cm into Bel Canto custom amplification.

The buffer stage is a discrete, low gain, low noise buffer that can drive 40A peaks into a 2-ohm load. It adds virtually no noise or distortion to the voltage amplifier output resulting in an extremely transparent audio power stage using only 4 high current output MOSFET power devices operating in an efficient self-oscillating analog switching architecture adding neither coloration nor distortion. The chassis design isolates these critical analog stages within a controlled, optimized environment, ensuring maximum performance under real-world system conditions. The BLACK system achieves a greater level of resolution by creating a greater synergy between technologies eliminating potential signal loss, so you hear everything as it was originally recorded in incredible detail, speed and musicality.
