    SAM1HF Schematic

    Is it available?

    It appears as though that the cd comp is part of the internal crossover.
    Can anyone verify this?

    Nope!

    We've been waiting for someone to reverse engineer it. Tag - you're it!

    Not until you run a voltage drive on the network.

    Send me a pair, and I'll get right on it

    (the real challenge would be persuading someone to disassemble
    a working/warranteed unit ... if you didn't have that particular driver
    and horn, why on earth would it be needed? other than as a design
    example or out of curiosity)

    No it's not! That Be 45 deg to the right side! Upside down is 180 deg...

    Curiosity. I would expect that they simply copied Greg's 1400 Array schematic but it's possible they didn't. When I asked Greg years ago he didn't know.

    Not only that, but it's a 435AL.

    I will pull the crossover today and get pics/values and confirm weather this is the case or not.
    Always fun learning more.......

    and no room for a 476Be with that inductor nearby

    Here's a link to the 1400 Array schematic, I bet they are pretty similar

    The component counts don't appear to match (L,C,R) vs. the 1400 schematic
    (more caps and resistors visible on the SAM board), but it could still be close
    or some elements paralleled.

    Sound like Junior's got it covered, in any case

    ... and I type too slowly.

    My thought is that it would be almost the same maybe minus the high pass for the 435al since they use the synthesis electronics to do the other half of the crossover between the samlf and hf.

    BTW I type even slower!

    Or the SAM12X
