I got this receiver about a year ago and have used it mostly to power my home cinema at relatively low levels. It's worked flawlessly with a 5.1 Klipsch speaker system.\nJust this week, I added a Fluance RT-81 turntable (with built in pre-amp). I hooked it up to the CD analog inputs and boosted the source input through the receiver by 10db.\nI played two albums without any problems (again at moderate levels). Sounded great. This morning I put on Dark Side of the Moon, and within minutes there was a "pop" and the receiver went into protected mode. \nTried factory reset, it would start to initialize and then go back to protected mode. Even called customer support (who were timely in getting back to me, but unable to fix the problem).\nAt no point has this thing ever been abused, or even played at very high volume. \n(I'm and old guy with no kids at home and my wife thinks it's too complicated to do anything more than turn on the satellite TV!) \n\nNeedless to say, I'm thinking that the turntable has a something to do with the failure, it just seems more than a coincidence.\nI'll be sending it off to a Service Center, but I'd like to avoid a repeat of this failure, and I'd still like to delve into my LP's from time to time.\n\nAny suggestions?
