You can send after Channel EQ to the Mixes but there is only one Channel EQ per Channel. Each mix has its own EQ (parameteric and graphical if necessary). There is no Channel EQ per Mix.
You could patch one input to several Mixer Channels and each has its own EQ and Sends then. Since the Mixer can handle up to 48 Mono Channels that may be a solution even with a number of Inputs.
Also you can choose your send points per Channel and Mix between after Preamp, after EQ, after Insert/FX, after Delay and post fader.
