I am trying to figure out where to tag the stereo signal from MV-1C.
As you can see in the image, the signals from red circled points
go through sets of resisters and capacitors and then merged into
one. I am wondering if those two red circled points are where I can
find the stereo sound? If they are, is it safe to directly connect them
to RCA jacks?

Ok just tested and comfirmed that if you connect the white circled points to RCA jacks, you get the stereo sound. : :glee:
Feel free to correct me if I am wrong thanks.


NOTE: The sound is not amplified.

I haven't messed with a 1C (other than changing the bios for some people), but this looks very simple. Thanks for posting your findings!

Just tapping at those points would give you a mono signal -- you'll need to break that trace between R102 and R95(?). So that you don't cut the actual trace, you could just remove those two resistors to break that path and then just solder the proper value resistor to the exposed pads.

You should go into the MVS test menu and test the audio to make sure that stereo is working properly.

Again, thanks for posting :) I know a few people were interested in this.
