The BLACK system architecture, consisting of the ASC2 System Controller and two MPS1 DAC/Amplifiers, incorporates numerous Bel Canto developed electronic and mechanical design solutions aimed at preserving the delicate audio signals. Digital processing and asynchronous interfaces driven from our Ultra Low Noise Master Clock circuitry ensures external noise from sources cannot corrupt, modify or color the original signal. Bel Canto’s ST fiber interconnect electrically isolates the ASC2 from the rest of the system, preventing random external noise from impacting sensitive analog stages in the MPS1 mono blocks. This eliminates ground loops and electrical noise pickup from environmental RF noise sources ranging from WiFi, Bluetooth, computers, cell phones or any other noise sources. Black is void of extraneous electrical noise; you only hear the music.
