Title: RGB mod coregrafx2/supercdrom2 - audio question
Post by: Cyborc on August 01, 2014, 03:51:25 PM
I have a grey Super CDROM2 and Core Grafx II unit. I'd like to RGB mod them. However, From my experience I always get audio buzzing when using scart cables with other RGB systems. Shielded cables help but the buzz is still noticeable while wearing headphones so I usually try to separate the audio by adding separate audio jacks or other methods.

Can I do the RGB mod on the core grafx II unit itself and run a cable from the core grafx II to my monitor and run a cable from the super cdrom2's av output to my stereo? I'm hoping if I do the mod this way there wouldn't be any buzzing since the signals aren't travelling together in the same cable.

you can.  the output on the coregrafx outputs simultaneously with the output on the CDROM

I recently component modded my Super CDROM.  I replaced the stock DIN socket w/ a 8-DIN socket and I dont have any audio issues at all.  I wonder if the RGB amp board you are using is causing the audio issues.

Yes... If it solves any buzzing thats another question entirely.
