The source for Embedder A is the audio coming in on the AES IN 1 and 2 connectors. The source for
Embedder B is the audio coming in on the AES IN 3 and 4 connectors. There are separate DIP switch
settings that are used to enable or disable each embedder as well as to set the audio groups where the
embedders will place the audio on the SDI output.
When the DIP switches are set as shown in Table 5-2, the toggle switch is used to enable or disable
Embedder 1. Each time the toggle switch is pressed up or down the Embedder 1 Enable mode will
change as indicated by the LEDs in Table 5-2.
When set to
Disable
, embedder 1 will be disabled. When set to
Enable
, the embedder destination can be
set when the DIP switches are set as shown in Table 5-3. Channels 1 and 2 from AES input 1 will be
embedded into channels 1 and 2 of the selected group. Channels 1 and 2 from AES input 2 will be
embedded into channels 3 and 4 of the selected group. If audio is not present on one or both of the AES
inputs, the respective channels of the selected audio group will be mute.
