Soul Calibur sound wiring questions....

NGT · Apr 2, 2005

well, here's the layout

http://www.crazykong.com/pins/Soulcalibur.pin.txt

the question I have is, since there is a speaker + and - on the primary harness, and although switched (which I will fix) and another speaker + and - on the auxilary harness....

-can I put the speaker + from the primary harness to pin 10 on a jamma adapter and the speaker + from the auxilary harness to pin L and then get stereo (I know it's not true stereo....but better sound?)

-or should I just take one to the 10 pin and then go the mono sound route?

-or, will the amplified sound be safe on the speakers in my cab so I can wire stereo from the outside rca style jacks in the picture below...?? or will I need a couple attenuations to lower it for the speakers?

Any advice would be appreciated!!!

You probably need to use the (-) for each channel respectively because of the way the audio circuitry is designed (not a common ground). Probably the easiest way to do it would be to put one speaker on 10 and L (like standard JAMMA, if your harness is wired for MVS you will need a switch) then two separate wires for the right speaker to A1 and B1. If you're goal is to use this with a supergun, like to inputs on a TV, you should probably use the RCA phono jacks, I am pretty sure these are line leveled like Q sound on a CPS board. Is this a system 12 game? The link you gave says Soul Edge but also says Soul Calibur. I have Soul Edge and it is system 11 and looks quite a bit different from Soul Calibur system 12 games. The pinouts may still be the same, not sure.

cheers,

Looks like Soul Caliber is a stereo game with the right channel connected via the aux harness.
Looking at the pin outs, I think its wired like this

L......left +
10....left -

A1.... right -
B1.... right +

Yes, but to do this you would have to cut the trace leading to pin 10, then solder a wire from B1 to the edge connector part of pin 10. Then you would need a wire running from the cut trace for pin 10 to the left speaker (-), and another wire running from A1 to the right speaker (-). It would really just be much simpler to have 1 speaker on JAMMA and 1 speaker on the extra connector.

-or should I just take one to the 10 pin and then go the mono sound route?

This would be the easiest solution of all. Then there is the possiblility of line-leveled output on the phono plugs.

I think that two speakers (1 jamma, 1 extension connector) and using the phono plugs will yield true stereo sound.

Yeah, to get stereo you must wire each speaker separately(or use the RCA jacks into a stereo system or amp).

System11 and System12 boards have the same input/output connectors, but only System12 boards have the RCA jacks.

So, why can't I use a common ground for the speaker -'s?

What I would want to do would be make a jamma adapter that send the pin 10 from the game to pin 10 on the extension.

Then put pin B1 from the auxilary harness to pin L on the extension...

and use the ground hooked up for the speaker -'s.....and play the game via MVS sound.....

Is this not ok?

No it's not OK to just use ground for most games. See this thread:

damn....well, guess I will have to just turn it into some sort of harness and mod the audio setup in the cab.

oh well, thanks for the info!

remember also that not only are the speaker - not grounded, but L & R speaker - are not common.

so would I have to ground the speakers? or leave them un grounded?

here's a question: could I put this board in an mvs setup, with speaker +'s going to pin 10 and pin L....and then wire the corresponding speaker -'s with a switch DPDT along with the ground wires that go to the speaker -'s in the mvs setup....the when I switch back and forth...it will be set for soul calibur when switched one way and mvs another way?

just want to make sure I am wiring this up right.

as a matter of interest what type is that audio output IC on the heatsink, it looks like a STK ????

lamens terms? no comprendo output IC o heatsink

Reznor007 · Apr 4, 2005

He's talking about the markings on the chip that is near the extra connector attached to the metal heatsink that sticks out of the board.

You can put this in an MVS cab, with a switch, but the speaker (+)'s have to go to L and B1, and the (-)'s have to go to 10 and A1. You could wire a switch to do this in one position, and regular MVS in the other position. Like 4PST switch maybe?

would it be ok to split one of the speaker -'s to both speaker?

Reznor007 · Apr 10, 2005

No, the way it's amp operates each speaker must be wired separately.

I flipped the L and 10 pins and just ran it in a jamma cab. It works and sounds great. I left the stereo option alone and just have mono sounds....but it's much easier this way.

Thanks for all of the help!

you can flip the L & R (L and 10) but never make the speaker - common ground, its OK with mvs but definately not with most jamma boards. And with jamma stereo boards do not make the left and right speaker - common, it will end up in sorrow.

I have it set up like this, so I should be cool right?

I tend to let my Soul Edge game do it's thing in mono as well

I don't play it very often anyways, 3D fighters just don't keep me coming back very often.
