Yamaha Rx-v 2500 problem

[Jimmy DK]

My Reciever switches off, and writes "check SP Wires", when I am watching movies with high volume sound.

I have checked the cables to the speakers, and they are properly connected.

They should all be 8 ohm, but perhaps some of them have a defect ?

Anyone having experienced this problem ?

Looks like this guy had the same problem. I didn't read the entire conversation, but possibly the thread can help you.

Yes I have seen this.

But I have no nails in my cables, and the problem is only with rather loud volume (But not to loud I think).

Your receiver is seeing a short somewhere, check your speaker connections at the receiver and at the speakers (it only takes a couple of strands of wire touching to shut down the receiver at high levels). Make sure not to strip your wires to long it makes it more likely you will get a short. The other possibility is a bad woofer or mid-bass driver in your speakers. A speaker can be bad and still play. A voice coil can short inside the speaker and shut down your receiver.

I think the problem is my center speaker, B&W CC6.
When I turn down volume on this speaker, then I have no problem.

I have changed the reciever setting from 8 to 6 ohm or higher. (I have 8 Ohm speakers, according to their specs.)

This has eliminated the problem so far.

My reciever has the YPAO function, and apparently it cannot measure a defect on the speaker, and the frequency curve of the center speaker also seems to be ok.

So, I think the problem is, that the center speaker is not 8 Ohm, but more likely 6 or 7 ohm, which could give the reciever problems, if it is set up for 8 ohm or more.
