As mentioned earlier, a separate DSP pipeline (DSP E) has been set up in this example to provide a SAP Dolby 2.0 pair,
with this DSP being positioned at the output mixer in this example. Shown below is the routing that provides this.

General Tips for Using Audio DSP
• Make certain Core Usage indicators show green following set up.
• Determine what positioning (input or output mixer) is best for the task being set up. Placement at the input
mixer provides the most flexibility (especially if the processed output may be needed for other processes).
• When performing significant changes like unchecking or checking (enabling) new DSP functions, always
press the DashBoard Refresh button to make sure the change is taken in on DashBoard and sub-tabs
correspondingly displayed are refreshed with the drop-downs that correlate with the DSP setup. If
DashBoard changes (such as channel routing) are done before refresh, the intended routing settings may
not actually take place and engage.
•
Where possible where a compound setup (like that shown in this example for DSP A) is being set up, it’s a
good idea to confine the processes to a single DSP pipeline. In this manner, the intermediate processed
signals will always be routed to the next function selected, without requiring any manual routing setup in
DashBoard.
• Audio lag (delay) will occur when RTLL is used. Using the Video Delay controls (or Frame Sync controls
and Input Audio Routing > Audio Delay controls where equipped), it is recommended to provide a 200
msec video delay (or 200 msec audio advance) to restore lip sync. As with all Dolby Encoders, restoring lip
sync for a Dolby encode/decode chain must also be considered. Refer to applicable manual(s) for more
information.
