First, I recommend you go through the Home Recording Soundcard Wizard. Go through the beginners version. It'll help you A LOT!
The
M-Audio FireWire 1814 Computer Recording Interface will record 8 channels at the same time, but it only has 2 built in preamps. Try using the wizard. You should be able to come up with a solution that has 8 inputs and 8 mic preamps such as the
PreSonus FIREPOD 10-Channel FireWire Interface with Cubase LE
