The Wadax digital components employ our own MusIC Chip 2 technology, a feed-forward error correction system that compensates for time, amplitude and phase errors in the D-to-A conversion path. Using the same technique – adding the inverse of the transfer function error to the signal – we realised that it would be possible to compensate for the bit waveform distortion in the USB interlink. But whereas in our DACs, we are dealing with a closed system of known elements, with a universal USB interface, the corrective applied would have to be user adjustable. Our response to this challenge is the Digital Waveform Control, a set of three rotary knobs that allow users to adjust/compensate for errors in the rise-time and amplitude of the sent signal as well as the spacing on the return channel (counteracting echoes and reflections). Users can establish three, pre-set compensations, to match the replay characteristics of different streaming services or locally stored files.
