I am the audio tech for Infinity World Percussion
(PIW). A huge factor will be learning the proper way to coil/wrap a cable so that it unwraps flat and perfect. Nothing will slow you down like a knot in your cable or a mess of cables all tied up together. Youtube has some great demo videos of the "Over Under" technique. Your cables will last longer, look better, and make your life easier if the kids learn this technique.
color coding is a time saver as well. You
cant practice setting up enough. I still see world lines that get out there and something
didnt happen right.
Best of luck and enjoy yourself
