Chapter 3: Operation
• Set the embedding mode to Auto. If the group is present, it will be
overwritten; if it is not present, it will be appended. The overwrite and
append errors are actually warnings that the operation is not being
performed.
• In SD-SDI mode do not overwrite embedded groups of 20-bit audio
samples with groups of 24-bit audio samples. The required extended data
packet information appended to that group may overwrite a pre-existing
audio group. For 24-bit audio embedding, use the ADS Clean feature
provided.
Mono Channel Audio Embedding
To embed audio on a channel-by-channel (mono) basis, preserving some
embedded audio channels while replacing others from external AES sources,
follow these steps:
1. Configure the input audio routing path (Input > Audio > Routing) by
selecting audio pair sources to the individual audio sample rate converters.
By default, SRCs 1-8 are assigned to the 8 deembedded audio sources
(DMX Grp1 Ch1/2, DMX Grp1 Ch3/4, DMX Grp2 Ch1/2, etc.) and SRCs
9-16 are assigned to the external AES audio sources (AES1a/1b, AES2a/2b,
etc.).
2. Configure the output audio routing path (Output > Audio Source Select >
Embedded Audio) by selecting sources to each mono embedded audio
output channel.
Each SRC (SRC1a, SRC1b, SRC2a, etc.) can be selected to any output
embedded audio channel, allowing for any input-to-output audio
configuration.
3. Remove or preserve existing embedded audio with the ADS Clean
parameter (Processing > Audio).
4. Use the Audio Group (1-4) Embedding Mode parameters (Processing >
Audio > Embedding) to select the desired audio group embedding mode for
each audio group.
•In Auto mode, non-existing audio groups are appended and existing
audio groups are overwritten.
•In Overwrite mode, the original audio is preserved using the settings in
step 2.
•In Off mode, audio groups are untouched unless the ADS Clean
parameter is enabled.
Example: Replacing Audio Channel 1 in Group 1 Only
To replace only embedded audio channel 1 in group 1 with audio from external
AES 1A source, follow these steps:
1. Leave the input audio routing path at the default configuration (SRCs 1-8
from deembedded audio, SRCs 9-16 from external AES audio).
