This amplifier is a beast. A little wide for a 19 rack but I took the sides off and made new mounts/ears. I am running a 4 buss mixer through a 4channel compressor/expander into the bx-3 and she performs like a charm. Never had an issue except the front lights. I have been using it in a studio as my monitor driver for 8 years. It's a very under rated amplifier for some reason but it has performed consistently for me.
