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.

Black is a highly-optimized audio system that communicates the most subtle detail in a recording. Black has the synergy of integration and the optimization of separates, creating one system to bring out the clarity and naturalness in music. Designed and manufactured by Bel Canto in Minneapolis Minnesota, the Black system delivers an unparalleled level of sonic realism. We invite you to take a look inside.

The Black system architecture incorporates the most advanced digital and analog audio technologies and a series of unique electronic and mechanical design solutions aimed at preserving the delicate audio signals. Black’s bold design isolates source and DSP processing in the ASC1, creating an ideal signal transfer to the MPS1 monoblocks where digital conversion and amplification takes place in an optimized environment. Each innovation in Black adds up to create an audible experience that is simply remarkable.

The mission of Black’s ULN Masterclock circuitry is to flawlessly re-time the digital audio signal, removing any jitter related digital noise before being sent to the MPS1s for final conversion to analog. In order to take full advantage of 35 Femtosecond clocks great care is taken in the physical layout of each technology that plays a critical role in overall signal performance. Each input is extremely close in proximity to the DSP core, Masterclock and power devices creating very short signal paths to the output, and maintaining the ultimate signal integrity.

Bel Canto’s ULN Masterclocks circuit push the limits of low phase noise and jitter. Our research has shown that lowering the noise levels well beyond previous limits provides the absolute transparency and musicality that defines the true potential of digital audio. The phase noise levels of our ULN Clocks are below 35 Femtoseconds from 100Hz to 1MHz, with a clock noise floor of -170dB we are virtually equivalent to the noise floor of 24 bit PCM audio limit. While difficult to measure, the sonic superiority of our ULN Master Clocks is easily heard.

Bel Canto FIR filters provide subtle sound contours for a truly natural sound quality. This is critical for 16/44.1 CD playback. CD playback is remarkably engaging and competes with any high resolution source when played through the Black system.

There are 3 selectable custom filters that allow the listener to control playback to their tastes, using last octave roll-off to create a more natural decay. These subtle filters adjust the shape of the waveform to more accurately mimic the natural sonic structure of music. Black is designed to bring recordings to life, the design process being constantly informed by regular experience with live music.

Filter 1: minimum phase filter- flat to 20Khz with minimal pre-ringing
Filter 2: minimum phase filter- -3dB at 20Khz with less pre-ringing
Filter 3: minimum phase filter- -9dB at 20Khz with least pre-ringing

The MPS1 monoblocks are highly integrated mono DACs and amplifiers creating the ideal digital conversion and the shortest analog path to the loudspeaker maintaining true high dynamic range.

We achieve this with the following:
Asynchronous Interface with Bel Canto Ultra-Low Phase Noise (ULN) Masterclock
Custom Bel Canto Discrete Analog Stages
Ultra-Low Distortion High Drive 250mA Gain Stage
Ultra-Low Noise High Speed Current to Voltage Stage
No Capacitors in the signal path
Ultra-Low Noise, Ultra-Low Distortion Bel Canto Custom nCore Power Buffer Stage
128dB Dynamic Range, <0.001% Distortion

The final stage before the loudspeaker output is a custom fully discrete NCORE low-gain power buffer built to Bel Canto specifications. This delivers up to 1200 watts into the speaker without adding noise or distortion.

This stage can deliver 40 amps peak. Black’s high purity, vibration isolated WBT NextGen speaker connectors complete the delivery of pristine audio to the Black’s loudspeaker output.
