This channel is such good vibes man. Love the way you explain everything and have no earblasting music or other distractions. I can definetely tell the differences even watching on my smartphone.
Ha! I'm glad I can hear the difference between the two, especially after switching from bluetoth earbuds to wired headphones! The anlalog still sounds good by itself, but compared to the digital, it's "duller"; the digital is much "richer" and fuller.
I have mine connected to a hifi by analog RCA jacks. Sounds so much better than it did out of the tv speakers back in the day. Only reason I could see to do this mod is for recording the signal into a computer. The RF sound wold usually have more hum than soundtrack so just a little humis part of the retro feel.
EE here. What your receiver is doing is muting the audio when it loses the digital signal, and not unmuting until it has resynchronized with the audio stream. This is done to eliminate the chance of a loud audio "pop" if you have, say, a bad digital audio cable. The cheaper D/A converters don't have this protection function built in. FYI, the digital audio signal in the SNES is probably not S/PDIF; it's more likely to be LPCM (Linear PCM). It's kinda like the difference between a .WAV file and a raw audio file. Nearly everything that can handle S/PDIF can handle mono LPCM; it's just missing the overhead.
The S/PDIF output is always active, even when the serial sound data is not. As I mentioned I've tested it with a number of different DACs and receivers (some far more expensive than the pioneer) and they handle it just fine. I think the issue isn't isolated to the SNES as I've seen the option on other devices to keep the digital audio output alive to prevent dropouts with certain receivers
The Brazilian version of the SNES Jr. actually only has RF, and all other SNES Jr. boards have a large unpopulated spot where an RF modulator can be installed.
you might be able to isolate the rf can by unscrewing it, covering the bottom with an insulator and reinstall it with plastic washers. only issue would be screws, maybe drilling out the screwholes on the pcb?
@@TheRetroChannel Thanks! I do have a mega cd that would be awesome to do maybe that could be your next video ;) Thanks again keep up the good work Cheers
Could you not add some dsp to the board to "upscale" the audio signal to 44,1Khz 16bit? It wouldnt change the quality but it may help the pero equipment accept the signal.
It's not so much an issue with it being 32KHz, it's down to how certain receivers handle gaps in the audio stream. "Upscaling" it is unlikely to solve anything and 44.1KHz would be a bad choice, 96KHz (3x) would be better but again that's not the main issue
Would it be possible to do a more extensive mod and isolate the output? I'd also want to replace the jack with a new one, as the old RF jack might be worn or corroded.
I don't plan on doing another version as there are already other options out there that isolate the output and replace the RF jack. FirebrandX has one that does just that, so that would be my recommendation if you need those options. I did experiment with isolation of the output and found it made no discernible difference when comparing the output on a scope. So I dropped that idea and went for the simplest implementation possible. I've also had a couple with a pretty rough RF jacks but they polished up pretty nice with a fibreglass pen.
If the chip has Nintendo on it, it's proprietary and will not be available other than stated. Most of the others can be sourced by searching the part numbers.
@TheRetroChannel I do have a NES power supply, could try that one maybe 🤔 I want to recap the SNES, I'm just not confident doing it. I've recapped my C64 (and got told online afterwards that I shouldn't have because the original caps will outlive me 🙄) and resurrected a PVR and PC power supply that had bad caps. So I'm fine doing through hole caps. Just don't want to kill my SNES by stuffing up a recap. 😬

Even with UA-cam compression I hear a difference in audio quality even during higher volume sections. I’ll definitely be SPDIF modding the console.

The output board isn't entirely passive, that chip is taking reset, data, clock, LRCLK, and wordclock and converting it to SPDIF.

The grunt as you pick the poofy boy up.
He c h o m n k.
I had 2 of those same early versions with a 60 cycle hum. I changed C63 & C64 and presto no more hum. They didn't require any mods.
Great video!

Great video thanks for info, can it also be done for the Sega mega drive?
Not possible with the mega drive unfortunately. Could be possible with the mega CD I guess, but only for audio generated by the mega CD itself.

really wishing for a hdmi mod for the SNES soon that leverages this for digital audio
2:48 Shit... My tinnitus is just about 7.8-7.9 kHz.... So when you played the empty sound it was quite noticeable for me.
cool video! crispy af
Good work!
Using a fiberglass pen might be an easier way to remove the conformal coating to expose the vias you want to solder to.
Maybe, but they're pretty thick. You'd probably end up removing a bunch of solder mask while exposing them
Hi, what kind of wire you used? Could you share the link? Thanks
I just added a link to it in the video description. UA-cam will likely hide my comment if I link to something outside UA-cam here

@@TheRetroChannel Ah! That's good to know. Thank you!
The Snes Jr was only released with RF in Brazil Funny enough,
Hello! Is there any store to buy cpu, ppu and other snes components?
Not that I'm aware of. You need to pull them from another snes

Is that a Logitech Harmony 700 on your bench?
650 but yeah same same
My SNES has that kind of buzz noise through the TV when I turn it off. Is that just part of the analog noise, or does that mean it needs recapping?
Sounds more like a ground loop, a different PSU may solve it. Or just ignore it, but yeah the caps should be changed if they haven't been already

Find a junk board with SMD caps and practice first. Practically anything made after the early to mid 90s should be full of em

Why don't you mod the SNES with a step-down-converter? Saves much energy and so lowers the aging of the rest of the console because of the heat.
totally. the analog audio is muffled
I couldn't hear any difference between them.
Most vinyls are recorded and mixed digital, so i see no reason to listen to vinyl.
Only the newer vinyl. Vinyl records prior to the mid 80s would most likely be analogue.
@@jimdavis6833 Read at the back how they boast that their record is digitally mixed and that now it sounds better.
lol being hearing impaired i dont hear any diffrence
Fair
