bit One HD VirtuosoDSP | 12 input channels | 13 output channels | 24 bit / 96 kHz floating point processing Just as the virtuous performer holds the absolute mastery of the instrument and the technique connected to it, the bit One HD Virtuoso features unique skills dedicated to the most ambitious OEM Integration projects and excels in the uncompromising Hi-End systems. This was made possible thanks to innovative functions born with the new software/firmware development and the upgrade of some key components in the audio signal path, which are crucial to reach new heights of listening pleasure. bit One HD Virtuoso allows the creation of an Audison Full DA HD (Full Digital Audio HD) system where the audio signal is transmitted digitally from the Hi-Res audio player to the Audison amplifiers equipped with AC / AD link inputs, preserving every nuance with maximum purity.
