okay so say I want to use just a power amp. I happen to have a 1000 watt Behringer. Eurolive I believe, it's super light, the whole thing doesn't weigh 5 pounds, but I digress. Would I be better running a modeler straight into the amp, or should I run into the PA and send my signal back on a monitor mix (my board has 6 sends so I have spares) or just get myself a small 4 channel mixer where I have more access to set my monitor volume and such on the fly? I know running through the PA and a monitor send will give me the same mix that is going out front and offers me a little more processing, like EQ and compression, and using a small mixer adds another layer of EQ and the advantage of a readily available master volume. or should I just say F'it and go straight from the modeler, to the power amp, to my speaker?
