JVC duplicator SVHS pin out

Discussion in 'Professional Video Production' started by Dewey V. \Marty\ Martin, Nov 3, 2005.

  1. HI

    I'm looking for the pin-out diagram for the JVS 777 series
    duplicators...uses the same 7 pin Y/C 358 plug found on the back of most
    u-matic machines as a dub in or out.

    Need to find out how to connet the 4 wires on a standard S-VHS connector to
    the right pins on the Y/C 358

    Anyone with a mnaul for the JVC 777 duplicators could help

    The dub signal on the U-Matic is *NOT* S-Video.

  3. Yes, I know. However, the JVC br-777 series duplicators use that same
    CONNECTOR as is normally found on a U-matic deck for Dub IN or OUT. As you
    know, this is a 7 pin connector. I am trying to find out which 4 of the 7
    pins are used to sent the duplicators a S-VHS signal, and which part of the
    sgnal goes to which pin. Obvioulsy, you don't know this. I hope someone
    who does will reply.

  4. Are you sure Sony uses the same Y/C 358 signal as JVC?
    I thought Sony used a lower-frequency hetrodyne.

    The JVC uses Y/C 629, not 358. Just connecting the SVHS decks up to a 3/4"
    decks with this cable - - even wired correctly - - will yield a black and
    white signal because the color is referenced to a different frequency.

  6. I can't tell you hopw much I appreciate that you have read my message and
    have taken the time to reply.

    However, it appears NONE of you have read my message correctly

    I am NOT tryoing to send 358/YC singals to a JVS duplicator...

    The JVS 777 series duplicators use the same 7 PIN CONNECTOR (sorry, I don't
    know the name) as is found on U-matics. I have the proper four ping S-VHS
    out signal....I am simply trying to find out whatch 4 of the seven pins are

  7. Perhaps if you had explained why you wanted to know
    (and/or what you were trying to do) it might have helped
    understand your question. Assuming you don't have the
    service manual (or access to one)?

    I tried to find the BR-777 recorder at JVC's professional systems web
    site. Doesn't seem to exist there. Must be quite old.

    He should just call JVC and attempt to find a service tech who can
    answer the question...

    I have the pinout for the Y/C 358 connector:

    Y (Luminance) is Pin 1, C (Chroma) is Pin 5, then 2 and 6 are grounds. I just finished converting mine to BNC jacks on my BR-S822U VCR's. The active pins follow the same trapezoidal pattern as the S Video connector, except that the Chroma and Chroma Ground pins are reversed.

    If you can't read those tiny pin numbers on the female connector, they simply go clockwise from 1 to 6 (1 and 6 are on top), with 7 being the center pin. The male connector goes counterclockwise.

    This connector also supports component video, but the VCR needs the upgrade board installed to use it. For component, Pin 1 is still for Y, with 3, 5 and 7 used for the colors - but I don't which goes to which as I don't have the upgrade board in my units. Pin 6 remains the common ground connection.

    Hope this helps - 5 years later!
