I'm very good with balanced analog audio, and know it very well, however, now, with a Voltair, PPM encoder, and sometimes a profanity delay, in the totally analog audio chain, en route to the transmitter audio processor, I'm wondering if there are a number of A-D and D-A conversions taking place in the Voltair, PPM encoder, and profanity delay, which now (cumulatively) degrade the final product. Our audio (that audio chain that I just mentioned), sometimes sounded different coming out of various exciters (using the exact same audio chain). There was a Continental 802B (dense sounding), a Harris MS-15 (amazingly clean), and now a Nautel 3.5 (producing the worst sounding audio of them all). I'm feeding a composite signal from the Omnia 11 into the Nautel. Before you all condemn me for doing that, also know that that is the way I fed the 802B and MS-15. We still have analog boards, so I don't, as of yet, have a digital signal to work with. I am wondering if I convert the console analog output, to digital (AES), and keep it digital throughout the audio chain I just mentioned above, if that will clean up my audio coming out of the Nautel. If I do that, do I have to watch out for clipping on the console A-D conversion, as we have some air talent that still peg the console meters? Any recommendations for a A-D converter to use, in this application?
