Whiny Sound MegaEverDrive x5

[Greenhawk84]

Hello,

I am noticing a high pitch sound going on when I have this flash cart hooked up to my stereo system through the Sega Genesis.  Just to test I put in a couple normal Genesis carts and I didn't hear it.  However, I think it goes away during normal play, and I can't notice so much when the game is actually playing.   This is kind of a fleeting issue, but I wanted to get it out there.  Some of you probably wouldn't notice on small TV speakers, only when cranked on a 5CH-7CH stereo system.  I only mention it because it only happens when I am using the MegaEverDrive x5.

There is a similar buzzing that I have when my x7 is on the main menu. It's just noise from the power draw. It goes away when you start the game up, like you said.

Do you have the original SEGA power brick?

Do you have the original SEGA power brick?

I do. It's all original from when I got it new over 20 years ago.

Must be you talking about VDP noise, it notable in some combinations of graphics on the screen. For example when bright text on black background. Those noise most notable when you use RGB cable, by some reasons. Probably because current in RGB wires, inside of cable, quickly switch from high to low level, when pixels switch from black to white, and this emits interference to the closely located audio wires.
