Sometimes, as self-sufficient, self-supporting performing musicians, we deal with constraints of mixer capabilities, accessibility to power amps / equalizers, monitor wedges, etc. So after months and years of gigs where we only have one monitor mix onstage, I grew tired of hearing lead vocalists at 140dB all night. I decided to put on my thinking cap In studying the features of our stage mixer and a small mixer that I own, I realized that with a bit of creative patching and use of the channel insert without interrupt feature of our stage mixer, I was able to create 4 separate monitor mixes for our band. Holy crap, what a difference!!! No more lead vocalist wailing through my wedge at 140 dB all night, turning my brain into guacamole!!! After I configured the external monitor mixer and explained to each bandmember Just tell me what you want in your monitor everyone had an exceptional time last night.!! What a relief, my ears are thanking me and so are my bandmembers. Word to frequently performing musicians: what ever you do, look into configuring your mixer / monitor system such that each performer has a custom mix. It makes all the difference in the world, and it WILL save your hearing.
