I finally got my MRX 520 repaired, which has been sitting on the shelf for more than 4 years now. A lot seems to have happened since then including the introduction of ARC Genesis. I tried to run ARC genesis but soon ran into a few hiccups, one of them being a "Critical audio problem". Apparently this is another well known bug with the ARC genesis software and happens when there is no arc file already uploaded on the receiver. The fix is to first upload an .arc file first and then run the measurements. See here:
around 2:35 in the video.
My hope/request is, do any of you guys have a sample .arc3 file for the MRX 520 that I can upload into the receiver before running the ARC Genesis? Since I never ran ARC on this receiver, I have no such file. I would be extremely thankful if somebody can provide me with one.
Thanking you in anticipation
Paul
