I'm sorry, but I don't understand this. Suppose you digitally attenuate a signal by, say, 24dB. How can you avoid losing the bottom 4 bits?
Or are you saying that, within the SB3, any attenuation less than 30dB is not done digitally, but is done instead by adjusting the analogue gain of the DAC's output circuitry? -- cliveb Performers -> dozens of mixers and effects -> clipped/hypercompressed mastering -> you think a few extra ps of jitter matters? ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=28133 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
