So I'm using the headphone jack on a MVS1FS to get stereo out as per the JNX tutorial.

I've noticed that If I switch the audio switch to Mono it is a bit louder than stereo.

Does the switch actually have an effect on the headphone jack in terms of changing from mono to stereo? (and does it to anything @ the jamma connector, which I assume is just always mono)

Thanks,
