Im still tossing up between an Mackie MCU Pro or the Euphonix MC Mix. One thing I read on the SOS website is that if you want to hook 2 or 3 of the MC Mix's up, you need to plug them into a network router. Bit of a PITA, my router is already full.
Also, if you're using the MC Mix with Pro Tools LE, you
*might* have an issue with it running on ethernet. Digi actually recommend you turn your ethernet port OFF for Pro Tools... gah.
