Audio Down Mixer and Mono Mixer Function
(See Figure 1-5.) 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.
