Hi all Ive spent many hours at the inlaws today wiring up the yamaha DSP-AX620 AV amp to the Q Acoustics 5.1 speaker package.(As they had tried,and it wasnt working properly)An old set up, i know, but one thats worked perfectly in the past. So all was wired i and gave it a test drive... I decided to play "saving private Ryan" as i know its a good tester for the surround.And it all sounded good until there was a bomb blast in the film.Then the amp displayed the message "check sp cable" and then switched off? Presuming this means "check speaker cable" i checked all connections..ie: + and - were into correct terminals..no stray wires..cable direction is correct and minimum impedence is 6 ohms. (which is the impedence of the speakers) The cable itself looks fine also. The speakers have a 15-75 wattage output which should be fine.. So what could it be??? Desperate dot com!!

Yes the amp does switch on again. And it stays on if at a low volume,but as soon as its turned up and theres any action type scene with a bit of boom to it,it switches off again.
All the wires are perfectly connected so know its not shorting.

i had the same problem with my old Marantz amp. each time i turned up the volume the amp will turn itself off. i see that you have already checked the speeker cable, but i fixed my problem by double checking the speaker cable and all connections to ensure that there was no stray wires causing an issue.
sorry i cant be much more help but that was how i fixed it.

i checked and double checked at both ends. unfortunately, the inlaws are away so cant get to triple check them. fingers crossed,that thats all the problem is!
