As I was working on the audio system installation at Little Elm High School, someone left a comment asking how we use only two outputs to each speaker stack when there are actually have 4 true outs (2 main and 2 Sub) from the amplifiers. Since Little Elm uses this type of configuration, I thought it'd be a great opportunity to take a look at this exact setup.
Here I explain exactly what's going on and how we make it work.
