how to wire a volume control?

[redfivexw]

I am trying to wire a cabinet with a neo geo board.  This is the newer, smaller board.  I dont see a volume pot on the board.  I have an old pot here that was in another cabinet.  It is three wires coming off it, i am wondering how to wire it in to adjust the volume, if it is that easy.

Center pin of the pot and usually the right side are shorted and connected to the board the other side is connected to the speaker.   If it rotates the wrong way then use the left side and the center.   This is based on the assumption that your pot is of the right value to make a difference in the volume.   Too high a resistance will give you a overly sensitive pot and too low will not change the volume significantly.

All the Neo Geo boards I've seen have a slide type pot for volume adjustment along a side of the PCB.  There are two: one is for headphone volume, and the other is for the cabinet speakers.  Remember that multi-slot Neo-Geo boards don't have standard JAMMA wiring for their audio since they are stereo.

there is no volume pot on a neogeo board, just 2 sliders. well the slider is a pot, but its not a knob, its a plastic stick

There is a small volume pot on the MV-1FZ board.   Only one that seems to have it.

I totally forgot about that, small plastic screw adjustment pot to the left of the jamma edge connector.
