5 Choose Input Mode > Fixed Format, and Input > 5.1 from the pop-up menus. These
define the signal coming out of your mix. (Input Mode > Monitor Feed sets the B-Chain
to listen to the selected monitor source, while Input Mode > Custom Format lets you
choose an arbitrary number of channels.)
6 Choose an Output Mode > Fixed Format, and Output > LCR from the next set of pop-up
menus. These define the speaker setup you’ll be playing the mix out of. In this example,
we’ve chosen LCR, which stands for Left, Center, Right.
At this point, you can see that once you’ve defined the Input and Output channels, the
“Inputs/Outputs” table of cells becomes populated:
At the left of this table, each channel of your selected Input occupies a vertical
column. In this example, the Input columns are labeled L, R, C, LFE, Ls, Rs,
corresponding to the 5.1 channels you’ve selected to be output. It’s possible to
specify setups with many more channels, in which case the left half of the table
becomes scrollable.
At the right of this table, each channel of your selected Output occupies a horizontal
row that intersects the Input columns. In this example, the rows are labeled Left,
Center, Right.
In this way, every Input column intersects with each Output row, making it possible for
you to assign how much of each Input is fed to each Output by entering values into
each intersecting cell.

7 To assign Input channels to Output channels, double-click the field where the desired
Input intersects the desired Output, and type a value to set how much level from the
Input to assign to the Output. Typing 0 assigns Input to Output at “unity” gain (0dB).
Numbers you type here specify tenths of a dB. Typing -3 assigns half of the level from
Input to Output. Typing -100 mutes that Input to that Output completely. Blank cells with
no value make no assignment. In this example, we’re typing:
a. 0 into cell L-1 to assign all of the Left source to the Left output
b. 0 into R-3 to assign all of the Right source to the Right output
c. 0 into C-2 to assign all of the Center source to the Center output
d. -6 into Ls-1 to assign a fraction of Left surround to the Left output
e. -6 into Rs-3 to assign a fraction of Right surround to the Right output
f. -8 into LFE-1 to assign a smaller fraction of LFE to the Left output (LFE is not
directional)
g. -8 into LFE-3 to assign a smaller fraction of LFE to the Right output as well (LFE is not
directional)
