[sdiy] Mixer levels

[Scott Gravenhorst]

I had this same question and it became an issue as I added
signal sources to my FatMan's VCF input via a mixer.  After
adding several of them, I noticed that I had some nasty
clipping to deal with and wound up trying to tweak down each
of the input pots.  That got old real quick, so I stuck a
rheostat in series with the filter's input resistor to
attenuate the mixture of signals.  Once I got the levels of
the individual inputs correct relative to each other, I could
eliminate the clipping by increasing the resistance of the
rheostat.
