I just setup my Super Famicom, and everything is fine and dandy, except I have noticed a very annoying 'humming/buzzing' going on. The more I turn up the audio, the louder it gets. I have tried on both TVs and got the same effect.
Is there something wrong with the cable, or the issue lies somewhere else? :crying:
Thanks!
Yeah, it was a cheapo ebay cable. Can you suggest me where I can get a good one without paying too much (Official Gamecube cables are worth at least a couple of vital organs).
Cheers =)

Are you using an official power supply, or one that matches the voltage/ampage of the original PSU?
I found with the NES that using a power supply with too low an ampage caused a loud buzzing sound on the audio - I'm guessing due to underpowered amplifier circuits. No other noticeable differences. :/
I am using a multi voltage PSU. I has 9v, negative centre and 1Amp - all that should supply more than enough juice, I guess.
Just match the ratings on the bottom of the console.
Could this be a ground loop? Does the frequency match the one of your mains?
Try connecting only the console and TV to the same power strip, then remove all other cables. Including ethernet, A/V receiver, cable or terrestrial TV and so on, basically everything that could connect to another ground potential.
I tried on two different TVs, in two different houses. Got the background audio noise on both.
Hm, well in theory 9V/1A should be OK - it's just strange that the problem only affects the audio portion when a noisy cable would normally affect both video and audio. I'm guessing you can't test the composite or RF connectors to find out whether it's the cable or the SNES. I'm also assuming you don't know anyone else with a SNES to test out either the cable or the PSU.
:/
Good luck.
Come to think of it, the picture is a bit fuzzy, not as sharp as it should be. I didn't think much of that because of the audio noise...:dammit:
This is a common problem with the Super Famicom. My SFC does the same thing. The only way to fix it is to either modify the console to have a separate audio output, or buy a higher quality cable, like the official Super Famicom RGB cable. It's wired for Japanese RGB instead of SCART, but you can buy an adapter.
Official Nintendo cables do it too. In France Nintendo sold the console with a good quality Scart cable. It's way better than those 3rd party cables, but there is still a noise in the background. Maybe wiring a separate audio port and using good quality audio cables can solve but I haven't tried it. These old consoles always have this kind of sound problems because of the low quality cables with not enough shielding perhaps.

All SCART cables will do it, but the noise won't be noticeable unless you're using awful speakers cranked up to max and it'll be worse with a worse cable.

the noise is very noticeable on my TV on even very low settings. Poorly shielded cables can have A LOT of noise.
I went with a mod to the console and put separate audio out on it. There is still a little noise, but can only be heard when loud - as you said.
My Saturn does this too, but it's barely noticeable. The only time you're really aware of it is when there's no other sound whatsoever, and that doesn't happen very often.
That's what's great about consoles that have separate audio outputs, like the model 1 Genesis/Mega Drive. Crystal-clear picture and clean, stereo audio.
Yeah? Only time I've EVER noticed is when I was using my XRGB-2+ with my headphones. When I plugged in my powered speakers because they weren't even close to maxing out I couldn't hear it at all.Originally Posted by Bad_Ad84
Or maybe I'm not listening hard enough. I'll load up my PS2 right now on my LCD.
I see. I'm using an official SCART for my PS2 at the moment. With the XRGB I was using a cheapo JSCART cable.
Update: Today I got another cable (Gamecube RGB/Scart) and tested it with my Super Famicom. It still does noise :( - I have noticed that the brighter the screen, the more noise I get.
Will an official Gamecube RGB/Scart cable solve this problem? I better know before wasting a lot of money on one :P
