Hi !
I just fixed graphic issues on my contra PCB ( thanks to Riptor and Shawn1976)
and when I test it in my jamma cabinet : no sounds..
I look at the original docs and see that the jamma connector on this board does not use the 10 and L pins for the mono sound.
I have to wire by the 4 pins JST connector :
1 left + 2 left - 3 right - 4 right+
my questions:
can I simply connect 1 and 4 pins to the 10 of my cabinet's jamma connector ,( 2 and 3 to the L of the jamma) to have a "mono" sound by my cabinet's amplifier ?
or do I need an external stereo amplifier with 2 speakers ?
Thanks for help,
Raphael
