    • can't get stereo sound from RCA sockets--SOLVED (post 8)

      Hi All,

      Just installed my kit and everything works great except for some reason, I'm only getting one working sound channel from the RCA sockets working. I've tried 2 different A broads and both show the same problem.
      The stereo sound from the RCA works with a normal B broad installed. I'm using a revision 7 with a PAL F+Cable with the kit. I've checked that everything is seated properly in their sockets, not sure what's causing it.

      Wondering if any one had any ideas to what could be causing sound to only come through one channel on the RCA sockets?

      Thanks, for any help.

      blaze.
    • I have stereo sound, however if I separate the left and right audio channels... The left channel is noticeably louder than the right. Not by a lot, but it is noticeable.

      I too am using sound directly from the A-board RCA's, my amp is the XRGB Mini set to about 30~34.

      I never noticed this before the multi cart, I also never tested it. I was playing around with sound trying to lessen the crackling, that's when I first discovered it.

    • Order some 3D Printed buttons and try holding volume down since it seems to work for many people, though not all, or if possible see if you can use something to trigger the volume down button temporarily just for the fix even holding down a simple wire jumper may be find if the button is completely dead - waiting on HAS & Feb Pre-Order of CPS2 Multi to arrive myself, hoping I don’t run into any of these issues

    • this is a very common issue that is unavoidable when you switch from mono to stereo, you have turn the volume all down then all up to reset to get the cps2 aware that you have switched to the stereo output. I'm not sure about the exact procedure but I always try many things to get to this.
      Any Multi MVS bug ? Before asking delete BUFF FILE on the SD card and Reset NVRAM procedure : Power on without cart, Press Start multiple times until it asks to press ABC + Start, Do it, Power off > Done
    • @ZERO_MILES almost no Japan game boards use -5v FYI... Certainly not CPS1, CPS1.5, CSP2 and CPS3.
      They ALL work perfectly fine/with sound, no -5v needed whatsoever!

      It's the American shit that most often needs negative voltages bro (Midway boards).

      My cps2 outputs sound without -5v with one of my superguns that doesn't support -5v
      Same, my Vewlix Capcom only outputs +5v and +12v (the official Taito JAMMA kit like so many candy cabs don't even include negative, because again NO Japan boards really use it).
      CPS2 works perfectly fine/with sound.


      Yes I'm using a RECO here so I could easily add a Negatron IF I wanted too, but none is attached in this image (and everything is still working fine).
      The (JVS) Wei Ya PSU Taito uses in Vewlix cabs totally lacks the ability for negative, +3.3v, +5v and +12v ONLY!

      Haha, see I wasn't going to even post this... I thought by liking Frank's post ZERO would realize his mistake and just drop it.
      As he is still insisting -5v is needed for sound I figured the time was at hand. :rolleyes:

    • I never said -5V is required for sound.

      I said QSOUND uses -5V.

      Still, I have to admit it -- I went to Assemblergames to double check the information, and lo and behold, there was a post saying you needed -5V for QSOUND output.

      So I decided to open up one of my CPS2 mobos, and -5V goes nowhere.

      So there you go, there is no need for -5V in this case, and I was mistaken.

      Nothing wrong with mistakes, we all make 'em... but if you wanted to take the time to research something, try to prove/disprove that above statement.
