Quick question: I have the Denon AVR 3802, and last night, I was working with my brother-in-law on installing some floor trim around the media niche he just built me. We were listening to a CD (so my Denon DVD player was on as well) and I was recording a show with the VCR and Satellite receiver. All of this is plugged into a Monster Power Conditioner (HTS 1000). He plugged in his air compressor for the nail gun, on the same circuit as my HT. I was out in the garage cutting some pieces of the trim, and I came in and the compressor was running (damn they are loud). What was nice is that I put my ears up to the speakers, and there was absolutely no noise being generated by the compressor. However, when it kicked on, my receiver shut down and came back on almost immediately. My DVD player, VCR and sat receiver didn't budge. Well of course seeing that freaked me out and I turned it off immediately so it wouldn't fry anything. My questions are: Did I do any damage to my receiver? I don't think there was a spike, but more like a brown-out, but can this hurt the receiver? It came back on and was playing fine, so it seems that all is well. Why did it shut off (and not the other components). I wasn't playing it that loud, and I thought the HTS 1000 was supposed to help with this? Does the Denon detect that the voltage wasn't high enough and shut itself down to protect it? Or was it just not enough power to keep it running (like a brown out)? This compressor was a dual tank, contractor type professional one (pretty big and heavy) so I imagine it was putting a good drain on the circuit (the lights dimmed when it came on). Bryan P.S. I know for a fact there are no shorts in the system, etc. It has never done this before, and only did it when the compressor kicked on. Once it was on, the receiver was fine. It also wasn't overheating, as we only had it on for like 20 minutes, and I have had it on for hours without any problems before. Just wanted to get these assumptions out of the way, so people don't ask me to check the wiring and ventilation, etc. I know it had to do with the line voltage, but just curious as to why.
