--> XDP4000X-List message posted by: "jonathan e. andersson" <fallout@brainwashme.com>
it *is* a rip off at that price-- unfortunately, i need one very badly.
however, i do understand the unilink protocol (and FPGA design) well
enough to make one, but it won't be cost effective (i'll still pay $300
for one) without a group buy or something.
how many people have more than one optical digital changer and need
these things, or want an aux digital in? if i could get 10-20 people,
it may be worth the effort.
also in that quantity (20), they would still be >$150...

The thing is you CAN'T make one--well it would be pretty darn hard! The
price comes from it being VERY rare in North America... Still $350-$400
is
excessive. To have an understanding of the UniLink bus well enough to
make
a Multi-Changer adapter is not easy--then you have to make the MCA and
that
requires a lot of work including finding also very hard to find UniLink
female connectors!
I guess what Pete *might* be trying to say is use an analog MCA (like
the
XA-C30 or XA-U40--no "D") and then make your own (active) optical
switcher.
You can even buy an active optical switcher, however they are also not
very cheap. I'd imagine at least $150-$200 for a device like that...
You
could also go with a manual optical switcher and just change the source
yourself (some use push buttons and other more expensive ones you can
use a
remote); but changing the digital source yourself is a little more
involved
than just changing sources on the HU.
One of these is not necessary for more than one changer, only for more
than
one *digital* output changer to be connected via digital output. You
could
use a much cheaper XA-C30 or XA-U40 (discontinued) MCA for analog
changers.
Furthermore if you have only one digital changer you could connect other
another analog changer(s) as well as the digital one using the standard
MCAs. Only when you have more than one digital-output changer does it
become an issue. Even then you *could* always go analog on the other
digital-out changer(s) keeping just one connected digitally...
