I've done the search thing, gone to the BBE website, and read all the info I can find, but I'm still confused... which BBE should I add to my rack? The options seem to be 362, 482, 482i or MaxCom. FWIW, I was thinking of adding a compressor in the near future (JoeMeek or RNC?) so the MaxCom might be most cost effective. So what are the differences between these models? Why do all of them apparently have two channels (don't I only need one?)? Any ideas of the $$$ involved? Thanx!
