The event was last night and went really well. The delay speakers worked perfectly after some troubleshooting with the networking.
Setting the delay and volume was easier that I than I thought it would be. That only took me a minute or two.
I put the wireless beltpack on a lighting stand to get it as high as I could, there were no issues with reception at all.
The owner of the venue came up to get a card from me because of how good the system sounded.
I wish I got some other pictures than the one below but I was short on time due to the troubleshooting.
Now I'm off to figure out a new mixer. I need a better EQ for the mic than what my Mackie offers.
Thank you to everyone for the help, I really appreciate it.
