Yamaha RX-660 Audio Receiver Help Please

nope just come crappy wires and needed 2 more speakers connected. the only thing wrong with it was a burnt out display bulb

its your levels they all have seprate volume adjustments in the settings. the centerchannel and rear channels will only work in dolby prologic. or suround. fronts will only play in stereo mode. its in the settings yull se center volume rear volume. you need all 5 speakers hooked up for the dolby to work proper. the center will put out the main sound followed by your left ,right fronts. the rears will add filler. hope that helps some. but yeah i have a feeling its the volume levels.

mostly shitty wires

wow hmm Idk what it could be.. are you sure you have the polarity right on every speaker? otherwize I really don’t know without being there and seeing how your wires are hooked up

Before you do that go to Wal Mart, or Kmart to see how cheaper wire is there first. Radio Shack gets kinda pricey.

Whenever i am testing recievers i usually use the first speaker wire i could find, but sometimes that wire could not be too great. Thats when i get ambitious, and search for some real stuff. Usually the more beefier recievers reject the thinner speaker wire more. In your case i would cut the wire ends off, and restrip them. Sometimes the wire ends could get crispy, and corroded.

Sometimes i found out that if you have frayed speaker wire ends the sound could be faint along with having too thin of speaker wire also.

I will see if i can post a thread on Audiokarma about it. I dont know much about modern audio.

any idea how to fix it?

it’s actually my aquarium filter.

there is a setting I had the same problem

In the background is that a water fountain or a leaky toilet ? lol Nice stereo set up !!
