Hey guys,
So..I've got a Marantz MM7025 that I've had a for a few months now. I love it. The only problem I'm having is from time to time the amp will shut off and I'll see the protect light come on. A few minutes later I'll turn it back on and all appears to be well. Also..this isn't at reference volume or anything like that. It happened last night just watching TV at a reasonable volume level. I should say that this amp is not rated for 4 ohm speakers, but Martin Logan has told me that it should work no problems. Also..I demoed my bosses McIntosh MC7150 and it actually shut off during operation as well, so IMO that rules out speaker loads as the cause of the problem. My AVR (NR1603) never experienced this, but I'm assuming current draw from the amp is quite a bit higher.
I live in a 2 bedroom condo built in 1983. My thinking is that its a power stability problem, but I'm using a Panamax M8-AV that is advertised to monitor for "brownouts" and act accordingly, but as I said earlier its only the amp that is shutting off. Is my thinking still possibly correct? The current demands of the amp exceed the other devices, so only it is affected? I've considered picking up a battery to help regulate the power a little bit, but I'm told that the same batteries that you'd buy to protect your network (which I also have..Cyber Power) are different from those that you would use in your AV rack. Is this accurate? Do I need an "AV grade" battery? Does such a thing even exist? I've seen some of these meant for expensive racks for over a grand..and that definitely isn't what I'm looking for.
Any ideas?
