And even after others pointed out that those jvc's were not all that well engineered you got another jvc. I'm guessing for a lot of your life that's not the reaction you would have had or we'd be talking about some old two channel system. "



For your information I blew out the center on my original 515. Either I drove it too hard or disconnected something before turning down the receiver volume.



As far as modern surround, formats goes, got plenty of time to catch up on that.



Pro-Logic suffices for now, and BTW, I do still have a working eight-track deck and at least 72 hours worth of tapes.

Perhaps you are waiting to see if blu-ray really is here to stay? Because many blu-ray disks use the newer high definition surround formats that are not compatible with what you have. And there are not often discussed issues with many blu-ray players downmixing to the original surround formats. Forcing you to use pcm.

"I do still have a working eight-track deck" that really says it all. At the time of their introduction there really wasn't any other good way to take music to your car. But as far as audio quality goes the only thing worse was a wire recorder. They died a well deserved death almost immediately upon the introduction of cassettes.

james you don't get it:

My setup does everything we need it to. The aforementioned 8-track is not the core listening platform in my system. It's just one more option.

8 tracks are garbage. But you're right about one thing, no point in wasting time explaining the current state of the art.

IT HAPPENED AGAIN!!


This morning I turned on my replacement RX-515V, and it sounded
suspiciously low. I pressed "Test" for the surround sound pink
noise, and sure enough, center channel dead.


It seems these receivers have a history of blowing center
channel outputs. And no, I'm not over-driving it. Even JVC
themselves no longer service 20 year old receivers. They
can't even look up this model number!

Is it possible you have some problem in your load (speaker) that's
causing it?

I realized after I posted this that you are probably saying that the
channel was blown before you bought it. However, it is possible that a
problem in your load (short or near-short?) could blow it shortly after
first turn-on.

Randy Yates:

Apologies for any vaguery in my latest
post.

#1. I EBayed the replacement RX-515V
one year ago, and it has been satisfactory
almost up to today(when I discovered no
sound from my center speaker).


#2. All speakers are 8ohm. This Receiver
specifies 8~16ohm load. My original
515 went for 19 years in this configuration
before losing its center channel audio
last June.
