This interface is the highest-performance digital audio interface. The interface is glass fiber optic based, making it 100% electrically isolated and allowing for incredible cable lengths with no loss. The unique protocol allows a very low jitter copy of the DAC master clock to be fed back to the source, creating a low jitter clock synchronous with the audio data system. The audio data is encoded and sent to the DAC, where it’s checked for errors and corrected before playback. The ProISL is capable of multi-channel audio and extremely high sample rates (much higher than any current standard). By using fiber, any noise generated in the source (CPU, drive, video processing, etc…) can be prevented from entering the DAC and the rest of the audio system.
