Audio A and Audio B
These items allow various audio functions to be set
up for the 2 audio processing chains.
Audio A (B) Destination
Selecting items in this menu allows the processed
signal to be embedded into any one of the 8 pairs
of the SDI signal.
Routing Style
This function allows either Stereo or Mono routing
to be selected for the audio processing chain.
Stereo Routing
When this item is selected a stereo
pair
may be
selected for routing through the audio processing
chain.
For example, if Source 3L is selected in Audio A
Source Right menu then automatically the Audio A
Source A Left will be changed to Source 3R. i.e.
Chain A would be sourced from pair 3 with a stereo
inversion.
Mono Routing
When this item is selected a single channel may
be selected for routing through the audio
processing chain.
For example, if source 5L is selected in Src Chain
A Right then the Src Chain A Left is not changed.
i.e. each channel is selected independently.
Note that if the routing mode is changed the Mux
selection will not actually change until a new input
source chain selection is made.
Audio A (B) Source Left/Right
This menu allows any of the input audio sources to
be selected for processing.
