What are you listening to? CD, DVD, TV, Radio? Many DVD's don't have much going on in the L/R channels.

What kind of processing/DSP are you using...
Have you set up the speakers with the OSD (on screen display)...

More info needed...

Do headphones work on the radio?

i am listing on cd and fm...i notice that if changes it to cd the screen display is not changing its still on a radio station and i bypass the surround mode...also check the level setting and put it on the middle...no a or b output but the all relay click i am going to try head phone tonight
