Various questions about building a Mame cab with J-PAC

Speakers don't require power. So again, your question doesn't apply.
The JPAC supports everything you need for quick and easy connection of all inputs, RGB+sync output, plus a few extras.
If you have a JAMMA cabinet that already works, then you DO NOT need to do anything other than add a PC, preferably with an ArcadeVGA card, and to be safe, cut off the power to the original power supply. NOTE, I said power supply. Don't confuse the ISOLATION TRANSFORMER as being a power supply. Chances are your monitor gets power from the isolation transformer (big heavy block thing).

Well my cabinet at the moment doesnt have a power supply and Im not well versed in how to wire things.
The faqs on ultimarc sort of answered my question, but they didnt go into any great detail about it, so I was still wondering.
That chart kind of helps.
RayB:
If you are going to MAME the cab and do not care about using JAMMA circuit boards in it, then don't worry about power supplies. All you need is your PC's usual power supply to power your PC.
The monitor, as stated, should be wired directly to the Isolation transformer, which should be getting its power straight from the plug that plugs in your wall outlet.
