Flex Buses.
For both input and output nodes before and after the card
internal buses, flex buses provide flexible-structure mixer in which any of 16
summing nodes (
Flex Mix Bus A
thru
Flex Mix Bus P
) can receive any card
audio input, thereby allowing several customizable mixing schemes.
Similarly, any of the 16 card internal bus signals can be applied to an output
flex bus mixer. The output flex bus allows cross-sourcing from Path 1 thru
Path 4 embedded internal Audio Bus sources to the Path 1 thru Path 4 discrete
output audio crosspoints.
Audio Delay Processing.
Each of the four paths offers an overall Bulk
Delay control, as well as Per-channel Delay Offset controls.
Note: Per-channel audio delay controls will allow individual delay offsets for
channels within a pair for PCM. However, when the card detects a Dolby pair it
will offset both channels an identical amount as set using either channel
controls. This preserves the integrity of the Dolby pair.
Output Audio Processing
The output audio processing subsection is built around card internal
16-channel audio buses corresponding to each processing path (Path 1 thru
Path 4). From this point, path-specific Audio Bus channels are directed to
path embedded audio channels.
The output audio processor chooses from the following inputs:
•
16 channels of Path 1 thru Path 4 Audio Bus channels
•
Downmixer outputs
•
Output Flex Mix summing node outputs
An Audio Status display shows the presence of each SDI embedded pair for
each of the four paths. Lock status and payload is identified (PCM or data
such as Dolby
®
D or E).
