[QUOTE="John Roberts, post: 50714, member: 126"] Re: Pro 2 AD Conversion - why high pass at 30hz ? A DC term at the input to an A/D converter would cause earlier clipping for one polarity than the other, thus lower "clean" dynamic range than with a HPF inserted. I would expect most A/D to be HPF to block DC while perhaps much lower than 30 Hz, likewise I would expect most signal sources to be HPF and not put out DC. Agreed the advice sounds a little funny.. not ha ha funny, but why? funny. 30Hz seems a practical corner for a HPF, but why would they ever need DC response? JR [/QUOTE]
