I have heard of a lot of people using a small mixer with their mbox (or similar piece of hardware). What is the exact purpose? Are you running say 6 channels of drum mics into the mixer, then sending the stereo out from the mixer into the Mbox? Are you using an I/O setup (mixer-->Mbox-->computer-->Mbox-->mixer) for monitoring purposes? I hope this question makes sense. Any advice would be great. I am just getting to the point where I need more than 2 channels from my mbox, and I want to look at all the options available before I decide to upgrade. Thanks!
