    multiple preamp outputs

    Post by rockinrob86 on Thu May 24, 2012 10:56 am

    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.
