I am trying to understand what these knobs do in a Premiere CS5 5.1 mix (See picture in link). What are these knobs called? When I turn the bottom one to the right, I seem to get sound transfered to track 6. I just don't know what it is doing when transfering the sound? Is it adding bass to the LFE and reducing it in the channel with the knob? Is it just sending the bass to LFE? What is this knob doing? As for the other knob on top, I understand it sends the signal to center channel but since the signal has already been assigned to the center channel, I just don't know what the knob is for. Helllllpppp!!! Or where can I find information on these knobs with no names.
