The window will show the appropriate parameters depending on the source chosen. See next sections for
a detailed description of the different source type configuration windows.
When the channels are configured, the table shows the identifiers and buttons with a cross to remove
them:
Figure 15: Audio channels configuration table with channels configured
If BGM channels are configured, two selectors appear at the bottom of the table:
BGM Auto Selection: If this option is checked, when the data connection of the BGM channel that is being
played fails, the decoder tries to play the next configured channel.
BGM Volume control with input contacts: This allows to use the input contacts (only available in E413,
E415 and E417) to control the volume of the background music being played. When input contact 1 is
active, the volume increases in 2 dB steps at 500 ms intervals. The input contact 2 decreases the volume
in the same way.
Please note that in the E417, if you use the input contacts to control the volume, they can’t be used to
trigger the analog inputs for the advertisements or emergency channels.
