Links please.

I bought some cable off monoprice a while back and its 12AWG CL2 Rated 2-Conductor Loud cable. Never gave me any problems with my old setup. I bought a BIC AMERICA DV-32CLR 31/2" 2-Way Center Channel Speaker off Amazon because it was cheap and I was tired of blowing multiple speakers.

Thanks.
Thats really not too bad of a center and its high quality speaker wire.
Are you running the wire through the wall? You say you replaced the wire. When exactly?

Well the wire is just a new cut off the same roll that I used for my previous center speaker. I didn't think the wire was the problem but I replaced it anyways. This was after two of my centers blew with the old receiver. I figured replacing the wire would be a good idea just in case. After that the 3rd blew. Then replaced the receiver and speaker and now I'm getting the new problem. The center speaker wire is not connected through the wall, its about 3 feet from the back of the receiver to the top of my tv stand.

Sounds like a short in the wire. Replace it again. Are you sure there is no bare wire touching anything other than the speaker and receiver? Are the 2 wires touching each other at any of the connections?

No, I have banana plugs hooked into the receiver and the speaker wires go directly into the terminals of the speaker. No bare wires touching anything except the terminals.
post #2378 of 3379
I have known banana plugs to touch each other.
Other than that I dont know what to say. It almost has to be the wire. I would replace it again. Dont cut a piece, just use the rest of the spool. If it doesnt work you can just put it back on the spool.

Oops, I already cut a piece. but its only a few feet. I'm not worried about it. I need to get another center, but I could hook one of my existing speakers up for now to test. Any suggestions on how to test this to see if it will do it again

Have you tested just the wire when it's not connected at either end? I suppose you could check the speaker itself right across the terminals (although this static resistance check may not yield a result that matches the typical impedance of the speaker). Then connect the wire to the speaker and check it again. If all seems well, this leaves the connection to the receiver and the receiver itself. Likely you've done all of this.

Did you strip and cut any of the wires near your receiver? Is there any chance a scrap of wire dropped inside?

You could try running YPAO with no center connected, to see if it gives an error or just fails to find the speaker. If it gives a check wire error, that would be a strong indication that something is wrong inside the receiver.

Hi tacomaguy20, maybe the problem is cause by the other speaker terminals and/or wires that short out through the center terminals.

Suggest removing receiver from the tv stand and remove all speaker wires from the unit. Take a magnifier and light to check all speaker terminals for anything (single stray wire) touching the chassis. Also see if the problem occur without speakers connected and by turning up the volume. Then connect one speaker with new short wire and test if it will pass. If good, add the next speaker and test again.

I'm not sure what you mean by other speaker terminals shorting out wires through the center terminals? Can you explain that more. I'm going to try what you suggested..I'll disconnect the speakers and turn it up and see what happens and then add back in the speakers one at a time.

I didn't strip any wires near the receiver. I cut the new wire for the center channel like you suggested and I hooked it up to the speaker thats having problems and it shows .03 ohms, when I connect directly to the terminals it shows 1? When I connect a working speaker to the center channel wire, it shows me 4.3 ohms.

One more question, how loud do you suggest I go without and with speakers and for how long to ensure no problems?

That .03 ohms just seems really low. Is the speaker that measures 4.3 ohms a match for it (same make and model, but a satellite or bookshelf as opposed to a center)? If so, then that seems odd. I'm not surprised the receiver can't drive it. If it's the same under dynamic load, it's basically a short.

They are different speakers but still 8ohm so I think it should show a similar load.

So I unhooked everything and I turned up the volume as suggested previously. The receiver can go up to about 10db with the radio before turning off (no error message) just goes into standby. With the computer hdmi connection, it seems to go only up to about -2db before turning off but I was able to get it higher by changing the movie/music modes. Btw it shuts off (no error message either). It shut off several times during my testing but never did it once say check sp wires. I didn't hook back up any speakers because I wanted to know what you think of this first. Does that sound normal to you?

Ok so I hooked back up a center speaker (one of my surrounds) and kept the volume below -5db and no problems so far. I hooked up the other 3 speakers as well and no issues. I don't have a full set since that one blew but these 4 seem good. Of course, the other center speaker seemed ok for a while as well until it gave me the check speaker wires error so I dunno how long I should assume everything is working properly. Should I increase the volume until the receiver shuts off? I'm assuming if it shuts off without the speaker wires error I should be fine. I'm just not sure I want to risk blowing another speaker that way.
post #2387 of 3379
I dont know whats normal under those circumstances but +10 is nearly maxed out and -2 is higher than I would ever consider turning it up to if I had speakers hooked up.

Have you tried Yamaha support? At this point it might be a good idea.

I've never had mine up to 10 dB. First, it would be very loud (too loud for me), and second I don't want it to start clipping and blow my tweeters. When you say you unhooked everything, do you mean the speakers as well?
post #2389 of 3379
Hook all the speakers back up and run YPAO to see what happens.
Why do you keep turning it up until the overload circuit kicks in? Do you actually listen at those extreme volumes?

I took Jchin's advice and unhooked all speakers, kept increasing the volume until it shut off. I'm guessing overload circuit or something. It didnt' say anything, it just turned off. I tried this with the radio and then with the hdmi input from the computer. Based on different modes/settings of the receiver it went to different volumes and then cut off. It never cut off before -2.0 but from the radio I was able to get it to 10db. Mind you, this is with all speakers unhooked. Then I plugged in the center speaker, turned it up to -5db and it played for a good 10 minutes or so. I didn't know how long to test it for. Then I plugged in the other 3 speakers. Currently I'm missing a speaker because of the one that blew so I have a center hooked up, my front 2 speakers, my rear left and my sub. The rear right is currently being used as my center speaker so there is no rear right at the moment. So I listened about another 20 minutes with all speakers hooked up at -5db and everything seems ok. I just wasn't sure if I should keep increasing the volume to test if I get it to overload again or if it gives me another chk speaker wires error message (and blows another center channel). I was listening to music played on my computer when it gave me the check speaker wires message before at about -8db.

You need to run YPAO so that you have a point of reference as to how loud you are really listening.
Your computer may be the culprit in all this. You have the volume control in the computer and the volume control in the 673 so you dont really know what level you are listening at.
If you insist on listening at extreme volumes I hope you have some decent speakers. Part of the reason you keep blowing speakers may be because you are just turning it up too loud.

I've run YPOA and my settings are as follows. Center is +3.5 at 12.8ft, front speakers at +6.0 at 16.4ft, sub didn't detect right so I changed it to +4 (12.6 ft) rear right is +1.5db (7.6ft) (from previous setup) and left is +2.5 (8.2ft). All speakers are set to small. crossover is 80 and volume on my computer was turned up to max just to test the system. I don't listen normally so loud. My friend came over and I was listening to some music and turned the volume up to -8db (which i figured it could handle) and thats when I got the check speaker wires error with my new receiver. Granted -8db is a little loud, but I don't think its eccessive with my setup.
post #2393 of 3379
What kind of setup do you have?
Keep in mind that at -8 if you add the pluses from YPAO you are basically listening at reference. For example your fronts are at +6 so at volume -8 they are at -2 reference. When you factor in the computer volume being at max I would imagine you are well above reference. Extremely loud to most people. Which is fine. If you want to rattle the neighbors windows I dont care but you shouldnt be real surprised when you run into trouble.

If i want to run my system at reference at what volume should i run my ypao setup?

Your question is worded funny.
If I answer it according to the question I would say that you dont set the volume when you run the YPAO setup. The AVR does.
If youre asking at what volume is reference after running YPAO the answer would be 0.

Is it possible to get this receiver to automatically go to Party mode in a specific input is selected (in my case, AV5 -- which is connected to a Sonos connect) and then go out of Party mode when I go back to HDMI Input 1?

Ok I see what you mean but since the center channel keeps having issues, what I'm wondering is what is really the problem I'm having? I wouldn't think a 90 watt per channel receiver would be blowing a 125 watt center channel even at a high volume. The front speakers at +6 are only rated for 100watts so wouldn't those be giving me problems long before the +3.5 center channel 125 watt speaker?

Not necessarily. Its not that simple. I dont have time to explain it all but you should do some research. Underpowering a speaker can be just as bad as overpowering it. Your amp is clipping so you are sending the speaker distortion.
And it can depend on the speaker.
