How come i can only adjust the volume levels on the center, surround sound left and right, and the sub, down but not up? is 0 max volume?

SOURCE: no surround sound

So your saying that you have no rear channel. Some recivers use a single stereo output ic for both sides on the rear speakers. you could have a defect with this IC . Anther thing Im sure you check3ed the obvious ie : the switch is on suround sound? If there is a front to rear fader is it in the middle? Good Luck

Please add a comment to your previous post next time, it makes it easier to see this post has a relevant history. I had to go check in your profile when I saw the word "still". Shooting in the dark, and saying the obvious(just bear in mind a month ago I was going crazy over a problem that ended up being the blanace knob turned to the right) - could it be that you're not using a digital signal? I'm not sure you can get surround with analog. Make sure all settings are for digital, and that you're using a coaxial/optical cable going from the DVD to your receiver. I hope you'll end up embarassed but happy. Good luck

Hey Tad, I have the same problem and perhaps a solution. I just moved to the other SW "pre-out" and it seems to be working..the green light is on . Whatever works i guess.

I had the same problem. Set the reciever on 6 channel stereo. On this setting, you should be getting the same sound out of each speaker. Isolate which speakers aren't getting sound. Now, on your speaker switch (the A/B button), select A. If that doesn't fix it, select B. If that doesn't fix it, try A and B (if you can on your reciever).

Now, when you switch back to pro-logic, make sure your a/b channel switch is in the position that worked in 6 channel stereo. Yamaha recievers have a memory, and when you switch various modes, it makes auto adjustments based on what you had set in the past.

Hope this helps

SOURCE: center speaker

I had the exact same problem. In order to "almost" balance the center with the other channels I had to give the center +12db gain and the other channels -12db. So after I got that far with level calibration I tried some tv sound, well the center although was playing sounded like the highs were missing and a bit distorted. This is the good part, I turned the volume all the way up real fast, somewhere near max something fixed itself, the center became very loud. Now it works just like new. Hope this helps. BTW, the problem existed the same for sub channel, so when the center started working so did the sub.
