5. Istruzioni per l'uso
5.1 Audio Mixing Modes
The receiver offers flexible audio output options:
- Mixed Output (MIX ALL): All four audio tracks from the transmitters are combined into a single output track. This is suitable for scenarios where a single, combined audio feed is desired.
- Individual Output (MIX None): Each of the four audio tracks is output independently. This allows for greater control during post-production, enabling individual adjustment of each microphone's audio.
