  Well, that depends only on how your mixer works, but yes - it should be.
  Don't forget that when you "hear" a 2v signal, it doesn't sound twice as
  loud as a 1v signal. The *voltage* of the output signal is doubled, the
  perceived *volume* the volume will be ahh, um, it'll be ahh....
  ....some sort of logarithmic amount bigger - but not doubled :)

  This seemed like voodo to me for a while as well - but now I often use
  the cv mixer on my modular as a voltage doubler, just plug the same
  source into two input channels...

  If yer average audio mixer does something different please clue me in -
  I've never looked at the schems for my Mackie (even though they're
  sitting in a file cabnet at home) but I think all those busses are just
  summing opamps.
