This is the full meal deal 16 in AND out firewire mixing board with pre-amps (not to be confused with the 1640, which is 16-in/2-out). Tons of aux/bus options for live mixing and/or recording straight on to your DAW. Comes with 2 extra 8 x 1/4" snakes for recording out + a brand new firewire cable with adapter. All in a snazzy Odyssey road case. I am going back to tape. No low-ballers, please and thank you, this is a killer deal. Adrian
