Got my Rotel RMB-1066 Wednesday and it was very minty. I mean it looked like it was right out of the box. Very psyched and hooked up immediately. Started in bridged mode 150 x 3 and let it warm up a bit running stuff from the TV. Then it shut off. Weird. Checked all the connections and polarity...good to go. Tried again....hour or so later....shut off again. Hmmmm. Fiddled around with the 12v trigger and input sensor mode. 12v trigger would turn the amp on, but would not turn it off. Sensor on mode worked sporadically.
Thought maybe my speakers, even rated at 8 ohms were causing protection mode to kick in. So, I hooked it up in stereo mode in 5 ch. Shut down again. I think the amp is defective and have contacted the seller asking for a refund. Just started the process and hope the guy is reasonable.
