Do you can made more this? > >Thanks >Bruno Hi Bruno, Yeah, the XA-U40D was pretty hard to find back in the day.- Now they're a lmost 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 wa nted to use the optical output.- My problem was compounded by the fact th at I also had two XDP-4000X processors so I needed to combine the three out puts and split them back out into two active links.- On the LED-based TOS LINK fiber drivers, the light output is pretty low to begin with.- Buildi ng an array of passive combiners just didn't work.- There wasn't enough l ight 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, th en 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 brighte r 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 ci rcuit board and enclosure I made, and then a couple shots of the finished p roduct for fun.
