ac and dc mixers - help please

2009-01-09 by b3nnysf

Hey Smoggers,

I have a question that I can't find an answer to, being that the
search function has been broken for a while here at yahoo....

what is the differences between the ac mixers and the dc mixers?

a. If I run audio into a "blue" dc mixer, does it mix the audio?

b. If I run CV into a "black" ac mixer, does it mix the CV?

and finally, on the mixer pro, if I invert the output of the "audio"
is that the same thing as inverting the polarity with the polarity
switch on the audio mixer?

thanks, forgive my ignorance!!

later,
ben

the circuit for the CV mixer is optimized for DC or CV, and the audio
mixer is happiest with audio frequency signals.
The audio mixer's pots have an audio taper, and a processor's pots have
a linear taper. Also, the audio mixer will reject DC offsets.

Having said that, yes, you can mix audio signals in a DC mixer or
processor. You can mix slowly varying CV signals in an audio mixer, but
things like transients, sequencers, etc, will come out funny. Try it
for yourself!

An AC mixer will attempt to center the signal around zero volts at a rate
determined by the value of the components used in the mixer.

If the INPUTS are AC coupled, the resultant mix will be an "average" of the
incoming signals.

A DC mixer adds what it sees at its inputs together, so the output is the
SUM of what is at it's inputs.
