[QUOTE="John Roberts, post: 67246, member: 126"] Re: X32 Discussion The symptom description "sounds" like zipper noise. Since the digital gain gets changed in steps, it multiplies that step change times whatever signal is coming through. The fix or remedy for zipper noise is to coordinate gain changes with audio zero crossings, so the gain step times zero audio voltage makes zero click voltage (zero times anything is zero). It is not clear to me how this could be corrected in one place and not everywhere. .. Caveat: This is pure speculation on my part, so it may be something else entirely. JR [/QUOTE]
