So I'm setting up my IEM board, which is a wired setup just for myself. I'm using an old Yamaha MX 12/4 mixer, kinda overkill but I've owned it for years and its not being used for the main PA. I get my signals from the PA by using the inserts on my Carvin RX1200 powered mixer. I've got six channels with inserts, so I can get a pretty solid mix going into the Yamaha board. Here's the problem, though. I know in order to keep your hearing there needs to be a limiter on all the channels in my IEM, but I'm unsure of how to set the limiter for a brick wall cutoff. Anyone wanna shed some light on this?
