Denon 3803 and Klipsch F3

[rafael]

I guess I'm new to this or don't know what I was getting into. I got the Klipsch F3 speakers over the weekend. I hooked them up to my Denon 3803 amp. The sound was great, but the amp shuts off after I turn up the volume to 30 dbs.

I've replaced all the wires to the F3 speakers. They now are using the Ultra 600 Monster Cables. I also unpluggled all speakers except one F3. I've removed banana plugs and tighten all wires. It still turns off the amp.

I've changed the configurations on the amp to support large speakers and decreased the channels sound output from 15 dbs to 40 dbs. It still turns off!

I have other Klipsch speakers and when I plug them in, turn up the volume... no problems.

Can someone provide some help?

thanks in advance!

check and make sure none of the speaker wire is touching the other side..... It sounds like a small piece of wire is touching.

Ya, it definetly sounds like a wiring problem. All it takes is one

loose strand to create a short circuit. Good thing the amp is shutting

itself off...definetly not something you want to rely on.

I would recommend completely disconnecting everything and starting over

with the wiring...but that would totally suck. If you're a bit daring,

what you can do is turn the volume up until it shuts off. Remove one of

the speaker wires from the back of the reciever, reset the reciever,

and then try again. Keep unplugging stuff until you find the channel

causing the problem. When you find the culprit channel, go ahead and

try to wire it up to the reciever again (being careful about loose

strands) and then also double check the wiring at the speaker end too

(take it all the way off and start again).

If the problem still persists, then remove the wire from the reciever

to make sure that channel was causing the problem. Then connect that

same speaker to another wire that you know is working...If the problem

comes back then there is something wrong with the speaker (which would

be very rare, but it doesn't hurt to check).

So ya, try all these things and then come back with some more data and

we'll see where to go from there. The reason the reciever is shutting

off is because it's detecting a short circuit. If it doesn't shut off

quick enough then it is going to damage itself, so this isn't something

you want to fool around with. And that's why I suggest just removing

all the wires and starting over. Plug one in at a time and test before

you add another one.

This is actually the most common problem I run across - which is cool

because the fix is usually free. On rare occasion a person ends up with

a cable that has a short somewhere in the middle...now those are by far

the most annoying.

Thanks for the reply to this post guys. I started having the same problem, and I was getting ready to switch out the reciever with a spare one my brother has, but after reading this thread I am going to go through and redo some wiring. Some of my wires were too short anyway and I was stretching it to make the connection. Maybe I can try this within the next day or two.

Thank you all for responding! I'll get some feedback shortly!

I have a Denon 2803 and and I can tell you from personal experience

that the cutoff for the amp is sensitive indeed. My main problems

have usually been the banana plugs I use becoming slightly loose.

Check speaker wires first.

The good Dr. Who has you on the right track. There is tons of

power for any Klipsch speaker with what the 3803 will put out.

A blown driver can cause this, too. Especially if it only happens at high volumes. Unplug each speaker systematically to see if one in particular is the culprit.

I have a Denon 4800 and it will shut off after a little time if the wires are touching. Usually on a heavy bass note. It's a great saftey feature for the receiver.
