different source signals

phono = for tuntables (needs preamp) but has nothing to do with a mic! * Should be: phono = for turntables (has extra preamp) This is the important difference:A phono input applies an eq-curve (RIAA) to the signal So it changes in principle the form of the signal, not only its loudness.they were talking about active and passiv mics. where is the difference? does a activ mic create a line in signal? and a passiv is for the mic connector with the higher sensitivity? I think an active mic has a little amp in it.1. question: if i use s/p-dif it doesn't matter what soundcard i use cause it's a digital signal and i don't use the D/A converter! right? or are there also differences in quality? If the soundcard is capable of sample/bit-true input/output then there will be no difference at all, since "difference" is defined by "at least one different bit" I've heard that on winXP- systems there are problems with bit-true in/out. So among bit-true soundcards there are no differences. Feeding with spidf doesn't use converters until the very last step, right: You can't here a digital signal.2. i asked because i wanted to buy an eq or such an dj mixer (is there an difference) but now i had the idea also to modify the digital signal (s/p-dif) on the computer and the get a modified s/p-dif signal! is this possible? when yes is there any loss of quality, is there any thimeshift and which software does this job? What exactly do you want to do ? Leading the signal digital to your soundcard, eq-processing it and then leading it out digitally or analogically to speakers, and the whole thing in real-time ? Maybe your driver won't accept this. But you can record, edit and then playback. Any sound editor will do the job, I think foobar and winamp also can have eq on playback.
