that MX3242X is only a SIXTEEN channel mixer.
it has 16 tape returns that you can switch to, for monitoring off say ADAT or whatever. YES they can be used for inputs but no EQ, no Aux sends, naught.
16 channels really should be enough, but whats always struck me as funny was that companies like behringer say "16 inputs" when 2, or 4 of the channels are dedicated stereo. thats pretty cheesy.
I recommend the alesis studio32. its actually similiar to that behringer youre lookin at (which isnt even available yet btw, im pretty sure) and goes for about $500.
has a very nice sounding EQ, 4 aux sends, 2 monitor sends (can be used as aux sends) 4 returns, and bussing as well.
Ive had TWO and had very little problems with them
