I'm working on a Japanese capcom cabinet, Mame works great now with J-pac and arcade vga! but this cabinet have a Capcom stereo amplifier and I'm wondering if I can use this amp with its speakers with my MAME PC. Anyone have idea how it can work?
-
I don't see why not (although I know nothing about this amp).
Seems you just need to supply 12v. I assume the audio inputs/outputs are probably obvious. Note apparently there needs to be an input signal connected for the amps to power up.

My Q-sound amp is a simple 12v car audio amp. Use it.

Thank you so much for the advices! My Capcom Q-sound amplifier come with its power supply but How connect the audio imput (L and R jack) to my PC?

Using something like this:

Minwah your last link do not work, I just need the connetor/adapter to audio PC output...please add a working link to this item.

You need an RCA stereo to 1/8 inch stereo adapter. Not sure what that would be in millimeters. Also not sure if your RCA connections are male or female off your amp.

As common as both of these jacks are there are a million ways to do this with a variety of cables and adapters. Ultimately you are going from a 1/8" stereo plug to two RCA/Phono plugs. You could buy one cable to do this like THIS ONE (http://www.radioshack.com/product/index.jsp?productId=2102974&cp=&sr=1&origkw=1%2F8%22+rca&kw=1%2F8+rca&parentPage=search) from RadioShack. With the advent of iPods and MP3 players, these cables are sold almost everywhere to hook up you iPod to a stereo.
If you have the original RCA-->RCA cable that came with CPS-2 systems then you could also use one of THESE (http://www.radioshack.com/product/index.jsp?productId=2103225&cp=&sr=1&origkw=1%2F8%22+rca&kw=1%2F8+rca&parentPage=search) instead. Although I can't find a link, you could also use a cable that has 1/8"-->1/8" with a female 1/8" to 2 male RCA plugs adapter.
If you already have cables laying around, then you might go the adapter route. If not, pick up a pre-made cable.

Just keep in mind that unless you are running a legitimate CPS2 board, you aren't going to get "real" Q-Sound. The Q-Sound chips in MAME right now are a "good enough" approximation to the real thing. Until the actual Q-Sound chips are decapped and analyzed, MAME just can't reproduce the exact output of Q-Sound since it's not known exactly how it works.

That's not necesarily true. The modern Capcom Q-Sound Format is based upon the Sony PlayStation Sound Format, with a few modifications, although the Q-sound label has been around much longer. Designed to support lower-end consoles, such as the original PlayStation and older PCs, the QSF's data is stored in an uncompressed form. There are several Capcom games on PC and consoles that use Q-sound. There's even a win-amp plug in that plays QSF files (see here: http://www.neillcorlett.com/hq and here: http://en.wikipedia.org/wiki/QSound). The modern Q-sound is an algorythm, not a hardware solution.

Take a look at this thread here discussing arcade chips being decapped and analyzed:
Linky (http://www.mameworld.info/ubbthreads/showthreaded.php?Cat=&Number=144271&page=0&view=expanded&sb=5&o=&fpart=1&vc=1)
"They're emulated in a black box sense, but there is no Qsound effect. It was discovered about 2 years ago that the Qsound chips are actually AT&T DSPs with a built-in program that makes them act like a sound chip and provides the Qsound effect. So once they are decapped and dumped it will be possible to have 100% perfect Qsound in all the CPS-2 and ZN-1 games, including the "virtual 3D" aspects."
I just think it's a misunderstanding of words here. ;D
