Creating a zoom meeting that is streaming a music recital. Need the correct Audio Settings for a live music setting.

I have a MacBook Pro and Chrome browser that I am using for a live music recital.  I struggle with knowing exactly how to set up the meeting with the correct audio settings for the Listener/Viewer.  Do I determine the correct audio settings when I create the meeting or when I actually begin the meeting?  I did this before and something wasn’t right but couldn’t determine what exactly was wrong. 

Grateful for some guidelines.
