Merge two signals

[abracadabraHomer]

Hi, I want to merge two signals (parallel FX), but they may not influence each other. Simple as possible, 2 in 1 out. Where is the answer....

(Nobody's gonna answer this one?)

To combine two inputs into one output, you need a mixer.

A simple "resistance mixer" or "passive mixer" (google for those phrases) will do you fine unless you're mixing several tracks at once.

You could also search the forum here for "blending", "mixing" and all related wordings

Ciao.

can U say "Mixer"??
not as in "stainless steel"
not as in "Schwepe's Effervesant"
not as in "with the dual, rotating spatulas"
but as in---
guitar + cello + drum + vocal1 + synthasizer + bass + piano
each one has it's own knob.
then there's the "master control" knob.
DO touch that dial!!!

You could use the Return sections of the Splitter-Blend at runoffgroove.com

I would use an OPamp configured as inverting unity gain section and add a second one to reinvert the signal. But for sure there are people here that know much more about this than me.

You can learn a fair amount about mixing two or more channels at these links:

And this is my own mixer project:

This may be even more relevant, if not overkill:


When R1 is in the center, both inputs will be at an equal level, towards either extreme, and each signal's relative volume will change.
