i'm pretty sure it's going to be a quick yes or no answer. i was wondering can i just buy any optical adapter instead of spending $100 for the sony one. i saw this on amazon.
Amazon.com: Toslink To Optical Mini Adapter: Electronics

I'm not sure if that will work because it doesn't have the ring like the sony one does. But the price is cheap enough, I wouldn't hesitate to buy that and try it out!

That Amazon adapter is just changing the connector type, mini optical to toslink optical.


the C90 requires one to convert from a coax type to the toslink optical, just that Sony's coax is a 1/8 in plug..

I am guessing that the output on the c90 is just coax SPDIF with a different connector, may be able to make your own 1/8 jack to RCA, then convert it to Optical.

does anyone know if the optical adapter is needed for a processor? or is the unilink cable enough?

 

[pyropoptrt]

The unilink cable just controls the remote turn-on for the xdp-4000x and allows you to select different settings; no audio is sent through that cable. You'll need an optical and/or rca cable to send audio to the processor.

I know that the xdp-210eq can accept RCAs as well as the optical, but I'll have to trust others regarding the xdp-4000x. I too would like to find a cheaper replacement as I broke mine years ago removing my HU from a different vehicle.

pyropoptrt used to own an 4000X, so he's on the level. I bought it from him... and sold it to ACRucrazy last month.

The 4000x can definitely accept RCA or optical input. The tough part is finding the adapter.

If you can get access to a wiring diagram, it's possible to "create" a coax digital out, but it's way beyond my abilities... the three pins on the 1/8 inch connector are basically ground, digital signal and 5v to operate the D210 or D211 adapter- the digital signal and ground are what's usually referred to as "coaxial" digital.

convert coax to optical

To use that adaptor you'll have to convert the digital out to a standard coax out on the c90. I don't know the specifics on how to do this but I know that audionutz had it done to one of his c90s. After that you need to use a potentiometer to provide enough voltage for that converter to send the signal through the fiber optical cable. I know that audionutz had this set up in camshaft's car. Hope this helps!
