Hey folks,
I'm doing a quick post here to get started - I'm at work right now and I can't spend too much time on this at the moment - but I will follow up more when I get home tonight.
I've discovered an intermittent hum in my signal chain and I discovered my 48-OB to be the source. This only happens occasionally, though: With the same configuration (everything patched the same way, the same equipment powered on or off, nothing changed), it will sometimes go away in an hour or so. This has to do with my audio equipment, and not with anything else on this circuit, as best as I've been able to determine.
The 48 has a two-pin power cord, and presumably there is a chassis ground that I could get to. Provided that I can determine that the 48 is the true cause of this hum, what can I do to resolve this problem?
I'm really confused because I'm using mostly the same equpiment as I always have, the only (and main) differences being that I'm now using my M-520 mixer instead of the M-30 mixer that I was using before, and I now have all of my outboard gear racked on two steel equipment racks.
Does anybody have anything to add here? Any comments? I'll post more information when I get home, since this whole grounding issue seems to be fairly complex.
Thanks!!
Jeff
