Some audio blocks are controlled by automation, and others may be set up to automatically follow other system
states; for example audio AB mixing may follow video AB mixing and Easyplay clips may drive voice-overs and/or
follow the up/down state of keying layers on Program or Preview.
Note:
When the audio option is disabled, the audio embedded within the source SDI video is generally passed
through the system completely unmodified. During AB mixing of video, audio will be cut between the input sources
(rather than faded). It is possible to insert a stereo voice-over if the LGK-3901-OPT-EAS option is enabled without
LGK-3901-OPT-AUD but this limited use-case is the only exception that allows audio mixing without the audio option.
4.5.2 Example Route Manager Templates
A range of different example Route Manager templates are provided for building custom audio setups within the
Configurator Tool.
•
16 channel embedded AB mix
•
16 channel embedded AB mix with 2 channel AES voiceover (EAS)
•
16 channel embedded AB mix with 8 channel AES voiceover
•
16 channel embedded pass-through with 2 channel AES voiceover (EAS)
•
16 channel embedded pass-through with 8 channel AES voiceover
Within the LGK-3901/DSK-3910 Web Page (see section 8.7) each example is described listing the following details:

4.5.3 Voice-overs
Voice-overs are used to adjust the combined levels of the background audio and incoming voice-over so as not to
exceed the original background volume. The diagram shows how Duck and Preset adjust the actual audio levels.
