Sega-Naomi

I recently purchase an official Big Blue Capcom Q sound cabinet. The game originally inside was the CPS-2 Marvel Vs Street Fighter.



When I installed the Sega Naomi Marvel Vs Capcom 2 board also with the Sega Capcom Naomi System Jamma I/O Board, the game worked fine but the sound was on full blast. I had no way of controlling the volume.



What I realized is that the CPS-2 A and B board automatically have a volume control on it (right next to the test button)



The Sega Naomi motherboard, on the other hand has no volume control.



How do I control the volume on my Sega Naomi Marvel Vs Capcom 2 when I install it in a Big Blue Capcom Q sound cabinet?

hi!



volume control is on Capcom Naomi System Jamma I/O Board. check it. it's a little black pot.

STV is correct. Take a look here:







The volume control is on the top-right portion where the square cutout is located.

Thanks guys for all the help its very informative but...



I installed my Marvel vs Capcom 2 but the volume is still on full blast and I can't adjust it even if I turn the knob. And more bad news: all the kick buttons don't work even though its attached to a kick harness (CPS2 kick harness).



Can my I/O be messed up? Is there a way to fix it?

this can help you about extra buttons configuration.

for that audio problem i don't know. maybe the pot is broken

Thanks that was extremely helpful. Got my kicks working.



On the link you sent me it says that for Switch 1:



"1. Switches between composite and separate H/V syncs. If it is set to "right", composite sync is selected."



When it says "composite" and "separate H/V syncs". Is it talking about the volume? If not what is it exactly referring to?



Thank you.

No, it's talking about the monitor input type. :smt018

Thank you guys for all your help. Now everything works. Kicks work and the volume works. I needed an av stereo cable to connect the I/O to the motherboard.



Thanks for everything with your expertise nothing would work. Happy New Year!!
