    multiple preamp outputs Empty multiple preamp outputs

    I built an SP8


    In some of the pictures, I see multiple outputs. There are resistors connecting the hot contacts on the RCAs

    What values are these resistors, and why are they there?


    I am assuming they prevent some type of loss that would occur from just wiring the outputs in parallel, correct?

    I usually use 1K resistors, the value isn't critical, it just provides a little bit of isolation between the two outputs,
    and isn't absolutely necessary.
