The H8000 is from the “studio world”
The H8000FW offers four channels of pristine analog I/O combined with eight channels of AES/EBU, ADAT, and S/PDIF I/O. New FireWire I/O now allows direct connection to your Mac or PC so you can directly patch 24-bit audio to and from the eight inputs and outputs.
I've been using mine in my live rig for over 10 years. In fact I have S/N 666 which is the test/beta machine from Eventide's Scott Gilfix.
