Bel Canto Black 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.
The ASC1 is an all-digital asynchronous controller with galvanic isolated inputs that eliminate the potential for noise to corrupt the fine audio signal from digital, networked and analog sources. The ASC1’s 64 bit DSP processor core controls system function, 32-bit volume and custom FIR Filters retains the highest level of accuracy. And at the heart of the ASC1 is the custom ULN Master clock circuit, ultra-low phase noise clocks with independent power supplies measure below 40 Femtoseconds, keeping phase noise and jitter to extremely low levels, ensuring pure sonic performance.
The ASC1 handles all audio inputs, ranging from a networked audio UPnP Ethernet, USB2, a suite of SPDIF/AES digital inputs and an Analog line input that is digitized with a high performance 24/192 ADC 2cm from the input connector. All DSP based control and filter functions are contained within the ASC1 with each FIR filter allowing you to set the tonal balance that best meets your personal preference. Just as a high performance analog preamplifier is critical to the performance of a traditional audio system the ASC1 is critical to the superior musical performance of the BLACK system making sure the signal is ready for digital optical transmission to the MPS1 monoblocks.
