Theres 3 in total, one left, right, and a centre one thats placed in a box, i guess it acts as a sub, should i be getting sound from these speakers by just connecting the jamma connection to the J-PAC, or do i need to do some re-wiring? --- End quote --- From the JPac FAQ ... --- Quote ---What about sound? The JAMMA standard is for only one speaker, mono sound. This is one of the reasons the J-PAC does not contain a sound amp. Other reasons are: There is no readily available 12V supply. Using the available 5V supply would not enough power. Using a separate mains adaptor would create issues with local line cord types. How do I wire for sound? There are several easy ways to do this: Use a sound card with an on-board amp. Either wire this to the speaker connectors on the J-PAC to use the cabinet speaker via the JAMMA connector or by-pass the J-PAC and wire directly to one or two speakers in the cabinet. OR: Use a set of mains powered PC speakers. Either remove the speakers from their cases and mount in the cabinet or simply place inside the cabinet. This will give the advantage of power stereo sound. --- End quote --- As others have pointed out, JAMMA standard is for amplified sound. It is certainly easy enough to bypass the JPac and use amplified PC speakers, but do yourself a favour and don't hack up the existing sound system too much (in case you want to restore). Cheers. |
