Introduction
9341 Functional Description
Audio Down Mixer and Mono Mixer Function
(See Figure 1-2.) The Audio Down Mixer function provides for the selection
of any five analog audio channel 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 1-3) generates an additional mono-mixed
channel from two selected 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.
