For a passive summing mixer is a circuit to combine two audio signals to one signal. Passive summing works generally ok, both with unbalanced and balanced circuits if all connected circuits are same type (mixed balaced and unbalanced is mixed business if it works as wanted or not). When the devices connected to all inputs →
WOW, this one is amazing! Rockstar developer presentation!! Join Dylan Beattie – programmer, musician, and creator of the Rockstar programming language – for an entertaining look at the art of code.
