receiver keeps shutting off

ok i have a Yamaha HTR-5940 and when i turn the voulme up its shuts off and says check sp wire. i checked all the wires but still keeps happening what do i do ?
 
Sounds like an impedance mismatch, which is causing the amp to run too hard and overheat. Check your speakers to make sure they Ohm loads are appropriate for the output.

Are you running more than one speaker per channel?
 
i have a 5.1 setup and all the speakers are 8 OHMs and i don't think its a overheating issue because its not getting hot at all ?
 
has to be a short somewhere. disconnect all cables from receiver and speaker, connect one speaker (without removing last) at a time and test.
 
ok i tried but didn't help.... does it matter what kind of speaker wire to use because im using 18 gauge speaker wire
 
1) edit: nvm, you bought the KLH HT-9900
did you make sure to connect the 2 fronts to the subwoofer? and the subwoofer to the front left right outputs on the receiver?

2) ? it didn't help?
so the first speaker you connected returned the check speaker wire error?

have you tried just connecting the front speakers?

the maximum theoretical distance based on resistance and wire gauge
http://en.wikipedia.org/wiki/Speaker_wire#Wire_gauge
do any of your wires approach or exceed 32ft?

most places recommend much shorter distances (see Table 1) [though as explained in the wiki, you can run longer than this, you'll just have worse sound output)

you might want to use 16 gauge for your surrounds

what speakers are you using?
I think this might apply: as volume/output power increases, impedance decreases
i think i've heard that some 8 ohm speakers will actually drop below 8 ohms under certain conditions

i think one exceeds 32FT and others are close

just get some 12ga and call it a day 😛 do not buy expensive wires.

Home Depot has speaker wires that are reasonably priced. The cut length ones, not the ones already in a spindle or roll.

I think it was 2 dollars a metre for 12ga if I remember correctly.

or use 12ga romex if you have spare wiring about and don't mind the stiffness and white shell.

Do you have a multimeter? Check the Ohms at both the speaker and at the end of the wires before they enter the reciever. It's possible the problem is the wire or even one of the speakers. It's unlikely that your speaker wire is causing these issues unless they are damaged or shorted, even at 18 gauge. It's still a good idea to swap it out for better stuff, but I doubt it will actually fix the problem unless you happen to replace a bad wire.

Your reciever is telling you there is an impedance issue which is causing an imbalance. Good luck.

well that means i'll have to wait till next month to get the copper speaker wire sense my budget is low from my pc build ?
