You are welcome. Once in a while someone asks a question that I know the answer for.
I've been driving the Stinger for nearly seven years and I still find out things about it. And forget things. I couldn't find the "on stage" or "audience" selection this afternoon in the sound settings screen from setup. I know it's there, I just can't find it. Heh. There's a backup selector when you click on "media", it's in the upper left corner below the "home" button. This backup selector I had not seen until this year. Ha hah. I discovered it by bumping it with my gloved finger when I reached for the home button and got something else. A few tries later I had identified the selector that lets you choose between on stage, audience or off. And so, it continues, the journey of Stinger discovery.
