I have been spending way too much time in the hyper forums lately. So here's something I found while working on the Roads Edge/Xtreme Rally audio. Multiple audio channels turned into mono by one simple mod.
After I did it on my Driving board I turned over my Revision 1 and there it was again. So I tried it on there and viola, sound from the jamma connector.
Removing the 3ch resistor and short the MONO connection. I took a piece of a resistors long leg and stuck it in the holes. Fit snug and its easy to remove if you ever change your mind. If you do change your mind, just short the 3ch space and its back to normal.
Now, I dont know the long term effect of this, I just did it this afternoon. I seriously doubt any damage would occur to your board, game or cab. That is, as long as you can remove the resistor without jacking up your hyper board. But do it at your own risk.
The one flaw is you cant adjust the volume level. BUT the volume it does give out is just right for me on my Candy. Not too loud and not too soft. Two flaws if you consider you are losing stereo sound. If you are connecting it to a pure jamma cab, then its mono to begin with.
I looked and I dont think this has been posted before. If I had seen it in the past, I definitely would have done this long ago.
Revision 1 boards are a dime a dozen, if the extra wiring was keeping people from getting one, this is a very easy solution for sound wiring issues. I still dont buy that extra 5v line stuff for the Rev 1. I have powered these boards from the harness for years and never noticed any overheating or connector damage. But, I dont leave them on for hours and hours on end like arcades would have.
