Behringer Quality Stereo Firewire 400 Capture Device, with (4) 1/4" phono inputs and a pair of Firewire 400 ports for power and daisy chaining multiple units together. You can capture all simultaneously on one computer easily. Doesn't come with any cables - firewire or 1/4" phono! I will send you a link to the disk image of the drivers that came on CD as well as a scan of the FCC warning. I used these to capture clean audio from tape decks, reel-to-reel decks and more with great ease.  Some of the units are marked with the 4-number Firewire serial number on the outside so you can identify individual units if you have multiple in series.
