Another input/output setting question. Why can't I set the channel level outputs for each audio source with the 990? This sure would be nice. I know my DVD players allow me to do this, but my Satillite box does not have a channel trim capability creating problems with getting perfect levels with this source (i.e. sub level setting that works optimally with my DVD player for movie output is to high for the dishnetwork satillite box output producing too much bass with dishnetwork programming). Any ideas fo rwhat I cxan do ?
