Hi DC, I didn't claim that FIFO's and master clocks were something new - they've been used in the pro audio world for a long time. However, this is the first solution (at least what I'm aware of) that employ these techniques for the SB3.
DC, your description of the how the FIFO buffers work are excellent. That's exactly where something like the PaceCar enters the picture. In order to prevent FIFO buffer over/under-runs the PaceCar is in control of the master clock. Since the SB3 is slaved to the clock of the Pace-Car, the buffer in the PaceCar will never over/under-run even though the incoming signal may have jitter. The buffer is then clocked out using a very low jitter clock. By employing this technique the SB3 can operate as a digital source with extremely low jitter. Whether the low amount jitter makes an audible difference or not is an interesting question. Anecdotal evidence shows that people are able to hear very low levels of digital jitter, and yes, I realise that I've opened up a Pandora's box by saying that! :-| Regards J -- Jaco ------------------------------------------------------------------------ Jaco's Profile: http://forums.slimdevices.com/member.php?userid=10726 View this thread: http://forums.slimdevices.com/showthread.php?t=37557 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
