Problems with RT1000P

[William509]

Hi one of my RT1000P speakers doesn't seem to work. Whenever I turn the volume up on the receiver, the receiver shuts off by itself at an "intense" scene. I thought the receiver was broken, but the tech said I should check the speakers. I tried testing it by plugging the speaker by itself. Anyone have any idea what is causing this ??

Thanks in advance

William,

From your description, it appears as if you are driving your reciever past its limit's. You mention this only occurs during intense scenes which leads me to believe you are experiencing clipping.

Some recievers have a built in pre-cautionary shut-off when the reciever is being driven past its limits.

My advice to you - Get a new, more capable and powerfull reciever that fits your demands. Clipping can also bust your speakers and then you are really up **** creek....

i don't believe it's my receiver, because when my receiver was at the tech, i bought another receiver to try it out. the results where the same. whenever i increased the volume, the receiver would shut off by itself. This only happens with that particular speaker... when i connect the other(working) speaker from the other side, nothing goes wrong when i increase the volume...

thanks for your help

Do you have the problem with th sub unplugged from the wall?

Can you hear sound out of tweeter and mid under normal conditions?

[Dr. Spec]

Sounds like the impedance load being presented to the receiver is abnormally low. Bypass the powered lowers and see if you get the same problem.

Dr. Spec that is what I was working towards.

umm i'm a newbie, can you elaborate a little more Dr. Spec? Thanks

schumach - i don't have the sub plugged in... , but I can hear things under normal conditions...

it just blows when i increase the volume :(

appreciate the help!

You don't have to power for the sub plugged in, but how do you have the sub connected? Are you using the binding post connectors or the line level input?

You may also want to pull each speaker out and confirm that there are no loose wires grounding out.

oh i don't have the subs connected....
I also pulled all the wires connected to the speakers... while having the problem speaker plugged in by itself...

I would have to say you have done every thing I would have. The only other test I would do would be to disconnect the tweeter and see if the receiver goes off and then the mid. If it happens with both then I would have to think it is the crossover. You might want to contact Ken at Polk tech support and see what he has to say. You have a five year warranty on the speakers. Other then that I am at a lose.
