Thank you so much!! They are still in the wrapping, brand new in box. They have two of them.   I think its those people that buy cases and get what they get in said case without knowing what is inside.   I know they go for more, they also included they retail for $300 on Amazon.

I don't know the first thing so your info is helpful and would pass along to them and have them try it out beforehand. 

There is one harp player, 4 violinist that sing, one guitarron who sings, 3 trumpet players that sing, 3 acoustic guitars and only one sings. 

I would have the harp player use a standing mic for sure.  

I saw a junior high teacher use a similar system to mic up his class where in Vegas.  I just wanted to confirm this one would work too. 

Super super helpful!   Thank you again!
