[QUOTE="Dan Mortensen, post: 96364, member: 2826"] Re: Monitor Out Whine The console came back from Las Vegas Repair, and I'll quote in full from the "Repair Details: Found Fault/Work Carried Out" sections: "Mute group 5 button works intermittently. MG #1 functioning nominally. Needs headphone rework. [B]Unable to recreate audio complaint from monitor output.[/B] No power cable or dust cover in box. "Mute switch 5 replaced. All mutes switches refitted. Performed all required manufacturer mods. Full functional check." (Emphasis added.) On a positive note, the mute buttons are all working nicely now, and the headphone outs do indeed seem quieter, although the 6k noise is still audible at full volume. Needless to say, the monitor output noise is exactly as it was, so I think it's fair to say that until the service techs are able to identify the problem, there is not much chance anything will change in that area. I'd kind of hoped that because I've been a squeeky wheel here about this noise, that the techs would be prepared perhaps more than normal to search for a problem, but apparently the analysis system used for such things is the tech's ears in whatever ambient noise field exists in the shop, along with whatever state their ears are in (meaning if they have a hard time hearing 6kHz or not). I say that because as has been shown in this thread, the problem definitely shows up in FFT analysis, so if they can't find it they are not using very sophisticated analysis tools. As a refresher for the reader, the monitor out volume control is actually an attenuator and not a gain boost/cut control, so that full clockwise rotation (to "max") results in unity gain through that system rather than an increase in volume relative to the source's output ("left/right" on XLR's 15/16 in my case). If your use does not require unity gain and you can turn down the Monitor Out pot, then you will probably not be bothered by the noise, as it is pre-pot. You also won't be bothered if you don't hear 6kHz very well. Other than that, the repair process was pretty painless, and quick; it was just about two weeks, which is very reasonable IMHO. [/QUOTE]
