arcade speakers SOS (solved)
<< < (3/3)
marioxb:
So speaking of Reactor, and other games that I heard use a subwoofer, like MK.. Is there a way to wire up and amp/ sub to the cab speakers and have it work for a J-PAC AND regular Jamma boards at the same time, via a 6 in 1 Jamma switcher? I want to have a universal volume control that would control everything. My cab is a converted Tekken 2 that does not have any negative 5 volts or volume control or amp. Can I use a PC/ car whatever amp to bypass boards that use -5, like MK? Is the -5 ALWAYS only for the speaker amp/ volume?

i know there is a way to connect speakers and woofer in to jamma harnnes cus my shocase 33" deluxe was connected like that but the bad think ya can only control volume from pcb. Well im making mine MAME so what i did i disconnect all cables from behind of the speakers and woofer and i ran new ones to the amp and from the amp goes to the pc ( sorry for my spanglish)

Unstupid:
You will have to check your board schematics and pick off the audio line level signal before it makes its way to the on-board amp.  If you can find the line level signals send those to the lepai amp....
