I am referring to making the music, voices and sound effects to be equal volume ratios. Like in COD Blops, I remember to get a perfect surround experience there was tweaking that was needed to get the music, dialogue and sound effects to be equalized. So one is not drowned out from the others, I dont know how else to explain it.

Currently mine is set to:
music = 30
Sound effects = 60
Dialogue = 85

Thanks
