Audio + Port Capacities
The system’s working mode affects its system capacity: Medium Band (without Siren14) and Wide Band (with Siren14). The Medium and Wide Band settings are defined in the system.cfg file.
For Medium Band, the flag is set to
AUDIO_PLUS_FREQUENCYBAND_MODE=MB.
For Wide Band, the flag is set to
