Hi, all. I'm new to this site, but I have a question that a lot of you will be able to sympathize with. I am the technical director for my high school's drama club. I want to build some parabolic microphones to improve sound quality for my shows without spending a lot of money on a seheiser or something. Does anyone know how to get information regarding this question? Thanks. I'm sure that many of us would like to be able to construct mics on the cheap!
