How do I know how much voltage does the SB audigy NX or the SB live! 24 external output?
In any case - I don't think that amplifying the voltage of a 1/8" plug is a good idea - that would amplify the external interference that this low-quality connecter already has.
Best thing (If I could do it) would be to send everything out via spdif to a more professional unit that would grab the SPDIF and output 4.1 outputs (RCA, XLR, whatever
So, to sum it up, the final questions:
1. Is there a way to output a 4.1 signal from the spdif of the audigy2 NX/SB live! 24?
2. If so - is there a sound processing unit (something like the audiocontrol three.1) capable of receiving this 4.1 signal and output 4.1 separated analog outputs? (preferably via RCA)
Thanks!
