3rd Step: Audio Sets
The 3rd Step: Audio Sets section contains the following steps:
• Audio Output
• Audio Input
• Audio Options
Each of these steps is described below.
Note There is a common problem when using Dolby Sync with 720 progressive
(720P50 & 720P5994), which is due to the fact that a Dolby frame spans two
progressive frame periods. To work around this problem, Grass Valley rec-
ommends using an SD interlaced sync rather than a Tri-level sync for the
Maestro reference sync.
Audio Output
The concept of the Maestro audio processing model is to provide a consis-
tent set of audio output signals regardless of the type of input source. The
Audio output screen uses a table that defines this set of output audio
groups which is carried through to subsequent configuration tables.
When the Audio Output table is first opened, use the set panel to create a
name for the set, and then select “New.” (The set is assigned to a channel,
that is, Processor, using the Channel Setup table, as described on
page 242 .)
An example of an Audio Output table is shown in Figure 81 .
