Many users require the use of stereo audio for their productions, rather than just mono. Using Switcher with a digital audio interface connected via the iPhone or iPad lightning port can achieve just that.
This audio adapter will allow you to use the RCA output from a mixer or PA (red and white connections typically seen on TV's and DVD players).
Keep in mind, some stream providers (like Facebook) default to mono audio for streaming. If you are broadcasting with stereo audio make sure you have enough available bandwidth and that your streaming provider supports this feature for video delivery. **May require using Custom RTMP option to enable for live.**
