Members Kaux Posted March 9, 2009 Members Share Posted March 9, 2009 Hi guys, as always seeking for the light of the wise men in the forum First... are all balanced signals +4dbu and all unbalanced -10 dBV? or you could have for example, unbalanced but +4dBu signals? Second... 0 dB doesnt mean at all in the analog world the same as in the digital worls. I understand fairly well what 0 means in analog world My question: Doesnt the "digital 0" has anything to do with the "analog 0" ? or was the "digital 0" chosen in an arbitrary fashion to be full scale?

Members WRGKMC Posted March 13, 2009 Members Share Posted March 13, 2009 Because Digital distortion sounds so bad anything peaking above 0db often sounds like a blown speaker. It also doesnt come on gradually or harmonic like it does in analog, it just breaks through. Since a digital medium usually stays that way during recording, CD burning and Playback, The playback equipment is calibrated to the 0db level. Having a disk burned above 0db will cause a playback unit to distort (or not play back at all) Same goes for a dics burner failure with levels above 0db In analog, tape saturation comes on gradually and can do it while producing harmonics that flatten much more smoothly and musically which is part of the sound. If you compare the two, 0db analog clean equates to about -9 digital. Therefore running at around -17db RMS or -12db Peak provides enough safety headroom where the highest peaks in the music dont go above 0db.
