I could be incorrect, but I believe that 0 VU represents -20 dBFS or 20 dB below full scale. A digital sample of sixteen 1s would be full scale. I think 20 dB below that is ... oh dear ... 0000001010001111. VU is an average reading, so if a recording is holding at 0 VU, then it's RMS power is holding at about 20 dB below full scale? I think the Slimserver VU meter is reasonably accurate.
Of course, I could be mistaken in all this:) If the VU meters are pegged, then there is a good chance the file is clipping against full scale, and the DAC is attempting to put out DC. -Ron -- Ron F. *Squeezebox setup:* wireless SB3 -> CI Audio VDA.2 DAC + VAC.1 PSU *Main rig:* NAD 7600 + NAD 2600A -> Phase Tech PC-6.5 speakers *Headphone rig:* Headroom Max -> Sennheiser 650s *Other stuff:* NAD C542 CDP, NAD 6300 Tape, Monster 5100 Power conditioner, Outlaw Audio cables ------------------------------------------------------------------------ Ron F.'s Profile: http://forums.slimdevices.com/member.php?userid=5616 View this thread: http://forums.slimdevices.com/showthread.php?t=35742 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
