Sometimes you may need a little help working with AUDIO TECHINCA wireless microphone systems. Such as selecting AT frequencies that would best work in your area, and checking frequency compatibility. I have used these tools for years. It is great for when I need to check local TV interferences and to select the correct frequencies when I am using a lot of wireless at the same time. Please check out the link below and hope you find this as helpful as I do.
