Quote from: zedrein on April 03, 2010, 07:29:55 AMI've got a few technical questions about the materials necessary to do this mod properly (found in the wiki)...if that's all right with y'all.1.) WIRE: What wire gauge/type is going to be most suitable for point to point wiring in this instance? I'd imagine solid conductor and small gauge wire is going to be easier to work with versus the stranded or larger gauge stuff, but will it still maintain that digital signal properly? I don't want to go with the ease-of-use route if it's going to somehow adversely affect the audio transmission/reliability or fidelity.
Quote 2.) CONNECTORS: I am leaning towards using a RCA type connector (as opposed to the TOSlink fiber optics connector) because the SNES chassis already has the proper "port" for that connector already in place where the RF out is. I know there is debate out there among audiophiles about which standard will sound better (which is strange because they both transmit digital and not analog information) but I'd like to know if there are some amongst you that think going one way or the other will be better sonically. Also, depending on which standard I go with what is going to be the best brand to purchase for securely mounting the connector to the SNES case? At the local electronics store they have a few nice gold plated connectors, but they look like they'd be difficult to mount flush onto the inside of my console, and my neurosis won't allow me to have electrical components just floating around inside there.
Quote3.) RESOURCES: I am getting pretty used to people telling me "Bro, ____ only costs a few bucks, trust me!" but when I actually get a hold of this stuff it usually ends up costing significantly more. So, if you massively intelligent folks would direct me to your favorite online electronics retailer that has reliable components at reasonable prices, I'd surely appreciate it. At the end of the day I'm still a dude with barely a working knowledge of basic electronics, but I still desire to make these old "retro" consoles that I still love so much better than I remember them, and I need all the practical help that I can get.

I know that I'm potentially asking too much on this one, but...can someone drop me some actual digital recordings from a SPDIF modded SNES? I figure there are loads of digital audio interfaces out there that have proper inputs for recording from a number of digital sources including the SPDIF format, and I'd sure love to hear how great the files would sound from a real life SNES...can you make a young boys' wish come true?
Quote from: acem77 on March 22, 2011, 06:59:40 AMI found a way to get around the nonstandard 32khz you need to supply another clock.my sony works ok with the nonstandard 32khz signal, my denon does not:(the problem is my denon replaced my sony when the sony lost some channels.I since fixed the sony but i dont want to go back to it as my main unit...after using another clock the snes worked on my denon but now there is a some jitter/static/crackle(not sure what the right term is) it can only be heard in some tone ranges. 80% time it sound nice, but i want it to be perfect.Not sure if the clock is off a bit? I tried a trim cap but still no luck.It could be noise in the circuit Lots of long wires/antennas

Quote from: zedrein on November 09, 2010, 06:52:36 AMSorry to be a pain in yall's bum, but I cannot find a DSP chip that will reformat all the raw digital audio of the SNES' sound chip into something a commercial receiver can decode and amplify (and, yes, my new AVR can receive non-standard sampling rates in case you were wondering). The original document that detailed this mod said to use Cirrus Logic's CS8405A-CS, but that chip is no longer manufactured and the new version, CS8415A, cannot purchased for under $13 US unless you are buying in quantities of more than 1,000!!! I clicked on the "request a sample" link on Cirrus Logic's own site and (when the page actually loads) it prompts me to enter a legitimate business e-mail account which I am not in possession of. DigiKey, Avnet, and Newark are all sites that supposedly carry this chip, but not without the strings attached that I already mentioned...please help me in finding a comparable alternative or a resource where I can find this IC inexpensively.
Quote from: duo_r on May 09, 2013, 01:15:43 AMHi modded mine last night. Everything works fine with the system however no digital audio. I am using CS8406 and everything appears to hooked up right. How can I tell if my receiver doesnt like the signal or not working?I dont have an oscope.
