Background music is distributed by using the Audio Program feature of AlphaCom. By default this feature is using the HD Voice codec G.722.
In installations where an even better audio quality for background music distribution is required, it is possible to use the HD Audio codec PCM L16/48kHz.
The following devices support audio input feed using the PCM L16/48kHz codec:
