[QUOTE="Tim McCulloch, post: 108583, member: 67"] Re: X32 Discussion I haven't noticed more hiss under the circumstances I use the X32. I use it in club and public environments and any residual noise is more than masked by the ambient sound. One of my guys used it at FOH for a bluegrass festival and didn't mention any hiss issues. Our systems are mostly set for 26dB gain. You have to hit them pretty hard to get full output. Dan Mortensen and a couple other users mentioned various noises in different outputs very early in this thread, a search might turn up some useful results... or not. Remember that a digital mixer's levels are referenced to 0DBFS. That means ZERO DB, FULL SCALE. That's the point at which you have, for all intents and purposes, run out of 1's. Full Tilt Boogie. Every digital product has a dBu output level that corresponds to 0DBFS, +21dBu for the X32. It is possible you're running things hot without realizing it. As for zipper noise, I think the users of <$20,000 mixers don't consider it to be a problem or have given up hope that manufacturers will fix it for their "value" models. Yamaha's M7 and LS/9 both have zipper noise (and a relay-switched pad in the M7 that changes the input impedance and therefore the sound) but I don't recall it in my more limited experience with the PM5D. I don't recall any zipper noise on the PM1D. No zipper noise on our AVID mixers, even the SC48 is zipper-less. I haven't spent any quality time with the A-H digitals but don't recalling hearing either way about them. Three or 4 years ago there was a discussion about zipper noise over at the ProSoundWeb forums that came about because a corporate client heard it at tech rehearsals and thought there was something dodgy with the PA. More a client relations issue, but the meeting planner had never heard it before and was concerned it would be present at showtime. As part of that thread, Really Smart Guys® that design mixers and other electronic stuff discussed the technical how & why and, IIRC, explained how decisions about performance vs. value decisions are made at the manufacturer's level.
