Hi Bruno,

Yeah, the XA-U40D was pretty hard to find back in the day. Now they're almost impossible to come across. When I did the install in my Corvette, I didn't know they made an XA-U40D, but I had three CDX-838 changers and wanted to use the optical output. My problem was compounded by the fact that I also had two XDP-4000X processors so I needed to combine the three outputs and split them back out into two active links. On the LED-based TOSLINK fiber drivers, the light output is pretty low to begin with. Building an array of passive combiners just didn't work. There wasn't enough light left to drive the XDP-4000X reliably.

So, I designed an active combiner/splitter circuit and put the whole thing in a nice project box. I used a standard XA-30 for the bus switching, then interconnected all of the fiber optics links using the combiner/splitter. After 8 years, the system is still working great. I really love the sound quality of the C90/XDP-4000X. I just wish the display was brighter on the C90. I've got no plans to upgrade the system in the Car or the Truck; still extremely pleased with the performance.

I've attached a PDF of the splitter/combiner circuit, some photos of the circuit board and enclosure I made, and then a couple shots of the finished product for fun.

Best regards,

Matt Dralle
