RE: TTL SPDIF -> TOSLINK

["BUTLER, Tony, FM" <tony.butler@xxxxxxx>]

Mark,

Check out a crative labs audigy or extigy to get a soundcard with
optical
out.
Nirvis in the states did do a digital distribution box, the DXS, but I
think
they've stopped production of it now.....

Apart from them, maybe try keene or lektrpoacks for a distribution box
-
can't say they do one for definite, but they _may_

HTH,


Tony
