If I should fall behind The usual method for data communication within a converter is I2S or similar. But the residual noise generated by this coding system contains a large audio frequency component, effectively in the form of a square wave, superimposed on the digital data and whose amplitude increases as the digitally represented component's amplitude reduces. The result is an inherent background level of jitter, ultimately responsible for a clouding of the air and ambience information present in the original digital source. To avoid this limiting factor within the DAX Discrete, all internal data is communicated by our proprietary N-Code method which replaces I2S and moves all of the radiated frequency components of the data coding well away from the audio band. But just as I2S is a poor internal data communication system so the transmission of the combined clock and data between transport and dac by S/PDIF (RCA, BNC, Toslink) or AES/EBU (XLR) places limits on the ultimate sound quality achievable. The art of the interface If we say that DAX Discrete is capable of giving ridiculously good sound quality with standard S/PDIF or AES/EBU interfaces then, with ASL, it simply becomes sublime. Audio Synthesis Link, or ASL, is a dual-ST glass optical interface, available on both DAX Discrete models and retro-fittable into selected transports. ASL removes S/PDIF's data induced jitter and rewrites the rules of data recovery and thus the possible analogue resolution available from digital sources. With CD sources the improvement an ASL connection makes over S/PDIF is of similar character to the increased resolution witnessed when using 24/192 or DSD™ sources - simply amazing. ASL is fitted as standard on DAX Discrete Variable and is optional for DAX Discrete Basic. 1 2 3 4 5 6 7 Next > © 2010 Audio Synthesis
