jfhamel 2007-03-05, 10:15 AM I have a NAD AV 716 tuner that was working perfectly well until yesterday. Now as soon as the sound is a bit louder it puts itself in a PROTECT mode and shuts down the volume. If I put the volume is very low it works fine. Does anyone have an idea of what the problem can be and how I can fix it.

Too bad we never got a response to the one with the (supposed) speaker problem - diagnosed by removing speakers... jfhamel 2007-03-05, 10:45 AM Thanks for the tip, I'll play around with my speakers tonight and let you know how it goes 987654321 2007-03-05, 08:25 PM It is not unusual for NAD AVRs to have amp failures. If you disconnect all your speakers, and the unit does not go into protect mode when you max the volume control; then you have an amp failure (ie assuming that you have no short circuits) I had a 753 once whose surround amps failed but the front 2 were OK. It would go into protect mode when speakers were hooked to any of the surround outputs. jfhamel 2007-03-06, 09:32 AM I unpluged all the speaker wires, reconnected them and now everything works fine. I noticed that one of the banana plugs had lost its plactic cover therefore exposing the metal plug and maybe causing a short. I covered it with electric tape just in case. Anyway, I cranked up the volume and everything worked. Thanks for the help free342 2008-04-20, 10:46 PM Im having same problem with my Marantz sr5001 , it shutdown in protect mode when a loud seen occurs. If i have it at -10db it will go into protect mode always at a certain seen in a movie. But if i turn it down to -15db it will work ok . But i really like it LOUD so i was wondering if my receiver just can't handle it. I checked my wiring and everything fine. I'm not sure if it makes a difference but i don't have any banana plugs or anything like that but my connection do have a little bit of copper sticking out , None are touching but i just wondered it that could be a problem. Sorry i am new at this , any help would be appreciated. Thanks | |
