Nope, nothing changed in settings. Funny thing is, when I first noticed the drop off I went to sub and gently put a little wiggle on the volume knob (while music was playing) and viola, level popped back up. So... simple .... has to be a contact problem in the pot. No problem, I simply ordered the new sound board that contains both controls (only way it comes) and problem should be solved right? Wrong! Much to my dissapointment, same characteristics. So, I guess I'm kinda trying to double check as to where other folks find the average setting kicks out plenty of realistic low end balance (whithout going over the top cause I realize some listeners can't get enough base, especially with movie playback

). If several owners concur that they too set the volume between 12 - 2 o'clock, then perhaps this is normal and my old soundboard had a problem in the opposite direction.

Still a little suspicious though, the base just doesn't seem to 'ramp' up as smoothly as before. Nothing up to around 10 o'clock..... then fairly steady up to 3 o'clock ..... then bang! way to much all at once. Geezzz, this sounds like it has to be in the volume control, but I can't imagine the odds of two units doing the same thing. Confusing .......
