Dom's right,...
from what I've read & determined from the manual.
I just didn't want to come right out of the gate and contradict the first respondent,... not being an actual DMT-8 owner, myself.
I think the biggest criticism of the DMT-8 was the limited HD space, (by today's standards), and the limited digital I/O, (again, by today's standards). There's no USB, optical, or S/Pdif output, but digital I/O's limited to a 50-pin SCSI port for hooking up a DAT.
That's what I've scrutinized, through my study of the DMT-8 (std).
Please, someone correct me if I'm wrong.
On the positive side, the DMT-8's sound quality has never been criticized, AFAIK, and it has all the whizbang editing capability that digital is famous for. Also, it has all the analog I/O capability you'd ever need.
I'd get one, if I had the room. Or, two!
PS: the full-version of the DMT-8 manual is available by download, from the official Fostex website. /DA
