    Question MV-1C Audio (mix and amp question).

    Still in the planning stages of consolation. I've googled for about 2 days with no luck.

    I've seen the stereo mod pictures for the MV-1C https://benheck.com/Downloads/Stereo_on_MV-1C.jpg. I've also seen a mod for a MV-1FZS board. There is a circuit design floating around by n00b on oshpark. https://oshpark.com/shared_projects/q6nKRQBW This board shows a "mix" input. None of the MV-1C stereo mods mention a "mix." The pictures of the MV-1FZS has a "mix."

    Does the MV-1C not have a "mix?" What is "mix" anyway? Am I losing anything by not having it? Has anyone used this board with an MV-1C?

    Thank you for any help or insight.

    Please refer to the Stereo mod section of this guide where it says: "The MV-1C board does not give Stereo Sound off the jamma edge so you will need to tap the sound directly from the chip to achieve Stereo Sound"

    Thanks but I did refer to that, I understand I need to tap the chip, however I see no "mix" pin as on the other boards. I'm asking if MV-1C has this mysterious "mix" pin or not. The mod board I linked on oshpark has L, R, MIX pads. I don't see any reference to MIX or what it is.

    EDIT: Logically I would assume you would just leave out the components on that amp board and just treat it as a stereo (L&R) amp with the mix section being unpopulated. Does this sound right?

    No it doesn't. You just tap left and right audio from the chips and run it to your rca jacks, no other work or boards required.

    The is to me what makes the MV-1C so awesome. The ASIC revision on the MV-1C has ALL the audio sent digitally to the DAC. The "mix" pad needed for other revisions is due to one of the sound channels being analog only. When I get my HAS Supergun in, I'm going to start work on a digital audio mod for the MV-1C.
