Audio Down Mixer and Mono Mixer Function
(See Figure 1-4.) The audio down mixer function provides for the selection of
any five embedded, AES discrete, or analog audio sources serving as Left (
L
),
Right (
R
), Center (
C
), Left Surround (
Ls
), and Right Surround (
Rs
) individual
signals to be multiplexed into a stereo pair (Down Mix Left (
DM-L
) and Down
Mix Right (
DM-R
)). The resulting stereo pair
DM-L
and
DM-R
can in turn be
routed and processed just like any of the other audio sources described earlier.

The mono mixer function (Figure 1-5) generates an additional mono-mixed
channel from two selected embedded, AES discrete, or analog input channels
serving as left and right inputs. The resulting mono mix channel
MONO
can in
turn be routed and processed just like any of the other audio sources described
earlier.
