(V4.0)
Provides down-mix audio routing selections that
multiplexes any five embedded, AES, or analog audio
channel sources into a stereo pair (Down Mix Left and
Down Mix Right), or selection of any two audio sources
to be mono-mixed to serve as a monaural source.
With an optional upmixer licensable feature activated,
any normal PCM stereo pair can be fed to the upmixer to
generate 5.1 surround sound audio which in turn can be
applied to six user-selectable channels.
• Down Mixer Selection Separate drop-down lists for Left, Right, Center, Left Surround (Ls), and
Right Surround (Rs) inputs allow embedded, AES, or analog channel
audio source selection for each of the five inputs as shown below.

The example below shows selection from various sources and the
resulting stereo pair DM-L and DM-R. The two signals comprising the pair
can be routed and processed the same as any other audio input source.
Embed Ch 1 - Ch 16
AES Ch 1 - Ch 16
AN-AUD Ch 1- Ch 8
Embedded Ch 1 L
Embedded Ch 2 R
AES Ch 6 C
Embedded Ch 4 Ls
Embedded Ch 5 Rs
Note: The stereo pair consists of basic L/R PCM signals with no
additional encoded information.
• Mono Mixer Selection Separate drop-down lists for Left and Right inputs allow selected
embedded, AES, analog, or the DM-L / DM-R input channels to provide
an additional mono-mixed channel.
The resulting mono mix (Mono) is available as an audio source for any of
the 32 destination embedded or AES output channels as shown below.
Emb Ch 1 - Ch 16
AES Ch 1 - Ch 16
AN-AUD Ch 1- Ch 8
Emb Ch 12 L
Emb Ch 16 R
Note: Selection of any two channels for mono mixing in no way affects the
source channels themselves.
