    I've just bought an old Sony EVW-325P pro Hi8 camera (DXC-325P docked
    with EVV-9000P). Could anyone tell me the polarity of the pins for the
    4-pin, XLR 12 volt connector so that I can make up a lead for a
    battery belt? Also, anyone who has experience of this camera, have you
    any hints on getting the most out of it?

    Thanks in advance,

    Industry standard--pin 4+, pin 1-.

  3. As with all Sony Broadcast, Professional, Medical, Industrial 12v 4 pin XL
    connections..... Going back as far as 1978 to the first camera and the first
    portable deck.

    Going back as far as 1978 to the first camera and the first
    Is this standard that recent? Various 16mm cameras have used the 4-pin XLR
    (4+, 1-) for many years, and I think some of the Arriflex and Aaton models may
    predate 1978. The Arri SR and the original Aaton have 4-pin XLR connectors
    mounted on their bodies. The Arriflex 35mm BL-1 has one and it debuted at the
    1972 Munich Olympics. Earlier cameras such as the Arri 16BL and the Eclairs
    used different connectors, although every battery I've ever seen has been 4-pin
    XLR (older standards may have been replaced and all the cables go from old
    style to 4-pin, but then I don't know). I do know that there are many other
    portable 12v units for audio and lighting that have this connector as standard
    but I'm curious as to when the standard was first set.

    So anyone know how old the 4-pin XLR standard for 12vdc power is?

    Asked about this on the CML (Cinematography Mailing List) and quickly heard
    back that the Eclair NPR apparently started this standard when it was
    introduced in the early 1960s. The reason for the 4-pin configuration was that
    this was in the days before crystal sync camera motors, so a pilotone signal
    was sent down pins 2 (-) and 3 (+), then split out at the battery to the audio
    deck. So it looks like this predates Sony in 1978 by a good 15-17 years.

    Hi John,

    I also have an EVV-9000P deck but need to get hold of a replacement battery. Do you happen to know what the model number of the battery is..??

    I know these are quite old but still do good a good job, I hope.. :)
