Audio Output Routing and Delay
Figure 63:
Audio Output Routing Format Parameter Symbols
The
Alignment Mode
parameters are found in the various output sources (
Audio > Output Routing and
Delay >
x
Output Delay
). The
Alignment Mode
parameters make it possible for you to use an
Automatic
delay controlled by the module (the default state). Alternately, the
Align Now
option aligns all of the
outputs according to your current conditions (when routing from AAP sources), and leaves them in the
same state.
The
Automatic
or
Align Now
alignment modes will attempt to align all audio and video within a group of
audio (processing channel 1 embedded ch 1-16, processing ch 2 embedded ch 1-16, AES outputs 1A-8B
or a group of audio expander output channels). This alignment will automatically compensate for delay
through the AAP blocks when audio is routed internally through the module. If audio is routed
external
to the module, automatic alignment is not possible (for example, routing audio though an AAP then to
AES output and looped back to AES input).
AES and Expander destinations can match delay from either processing channel, provided its native
routing delay doesn’t already exceed the delay in the associated processing channel.
If
AAP 1
Delay
is greater than
AAP2
Delay
, AES alignment with
Processing Channel x
is possible.
However, if
AAP 1 Delay
is
less than
AAP 2 Delay
, AES alignment is not possible.
Figure 64:
Audio Delay Alignment
A fixed amount of video frame delay is added to the video path to align with the AAP delay. This delay
can be seen in the
Video Sync and Delay x > Actual Video Delay Used
parameter.
