Example Multiple DSP Process Audio Routing and DSP Setup
In this example, single DSP pipeline DSP A is setup to:
• Receive an embedded PCM pair from the basic device input audio (input mixer positioning).
•
Upmix the PCM stereo pair to 5.1 audio.
• Perform Real-Time Loudness Leveler (RTLL) loudness processing.
• Output the processed 5.1 complement as PCM and as a separate Dolby Digital 5.1 Encoded pair.
• Provide a separate additional Dolby 2.0 Encoder (on DSP E) for a SAP stereo PCM pair.

The upper pane on the Audio DSP tab allows enabling DSP processes for each of the eight DSP pipelines. In this example,
DSP A is set to provide Upmixer, 5.1 RTLL, and Dolby Digital 5.1 Encode by checking the corresponding boxes. In this example,
all processing is positioned at the Input mixer.
The Core Usage indicators provide an OK/Overload status indication and core capacity utilization percentage.
Make certain when set up that Core Usage indicators show green. Red indicates core capacity has been exceeded. It
is good practice also to make certain neither core is exceeding 80% or so. If core exceed is being approached, spread
some functions to another core (e.g., move some processing functions from DSP A-D to DSP E-H).
