    Hi All

    I was watching a dvd today (derailed to be exact) and all of a sudden the sound dissapeared, i checked the amp and the red light was flashing on and off quite fast and there was no writing in the middle.

    After a bit of investigation ive found out its happening on jumpy scenes or gun shots etc when the sound is at -15 or ABOVE if it is below that it handles fine and carrys on.

    this has never happened before and usually play film around -10 or lower sometimes for demo:thumbsup:

    Has anyone had this problem or can anyone recommend any help or where to begin.

    Does the amp have good ventilation, and what is the impedance of the speakers it is driving?

    Sounds like it's overheating and shutting down. It's worth having a quick check of speaker connections just in case there's any stray wires touching the casing at all.

    Whats the sound level? Set down with an SPL if you have one and see what it reads, set the SPL to Slow and C waiting.

    Hi all

    Im not that techy so ill try my best but thanks for the answers

    i looked at the back of the amp and all cables seem fine

    its sitting in an arca cabinet with the centre speaker above it, it was pretty hot when this was happening so i switched it off and left it a good 4 or 5 hours so it cooled down and then 1 hour into a film it happended again.

    i used to have the se version the model below and this never gave a problem in the same position.

    the speakers im using are pmc fb1s and tb2 + as the centre and tb2s to the rear, with a couple of rel strata subs.

    does this give you enough info and what do you guys recommend next.

    Thanks again for all the info guys im really greatful:eek:

    Still sounds like overheating to me. Easiest way to check is just take it out of the cabinet for a movie (if possible) and see if it still shuts down.

    Thanks Jase

    i will try that later

    although it only does it on the certain parts and the same parts of the films i watched, so for example if i try it soon and go straight to that part where it cut off and it does it does that mean we can rule out that problem

    cheers

    If it did it straight away when the amp is cool, yes.

    Check your speaker drivers/tweeters as well.

    Hi All

    After a lot of investigating it was the ex 7.1 speakers that were causing the amp to cut out.

    reason was i had my projector sitting in the window cove with the ex speakers either side, the heat must of been causing the problem, ive moved them now and all seems to be ok.

    Thanks for all your help guys.

    Cheers
