Hello Rich and welcome to the Cow Audio Forum!
Without knowing a lot more about your specific venue, making recommendations is fraught with peril. How big is the space? How many people were there?
You said no one could hear anything. LITERALLY?
Even good, basic PA audio is not plug and play (as you have experienced).
Can you please be more specific and also post without all of the formatting cha-cha-cha?
Thanks,
Ty Ford
