The passive mixer circuit consists of four identical audio inputs and one audio output. All GND connections are connected together. Audio Input Wiring. Audio jack GND (pin 1) to potentiometer GND; Audio jack right channel (pin 2) to potentiometer wiper (front) Audio jack left channel (pin 3) to potentiometer wiper (back) Potentiometer Output Wiring
Passive Audio Mixer W/ Channel Volume Control : 6 Steps ...
https://www.instructables.com/Passive-Audio-Mixer-w-Channel-Volume-Control/
This Audio Mixer mixes multiple audio inputs to a single audio output, with knobs to control the volume of each channel. My particular build features 4 stereo RCA inputs mixed to 1 stereo RCA output. You could easily alter this design to any combination of jacks that you need. This mixer is passive, meaning it requires no external power. It also means that nothing is amplified.

“Passive” Current Mixer +LO −LO +IF −IF +RF −RF +LO The input stage is a Gm stage similar to a Gilbert cell mixer. The Gilbert Quad, though, has no DC current and switches on/off similar to a passive mixer. The output signal drives the virtual ground of a differential op-amp. The current signal is converted into a voltage output by ...

An astonishing feature of this design lies in the fact that a complete stereo mixer as shown below in the Block diagram draws less than 6mA current! Block diagram: Input Amplifier Module. Circuit Diagram: Parts: R1 = 22K - 1/4W Resistor. R2 = 22K - 1/4W Resistor. R3 = 47K - 1/4W Resistor. R4 = 47K - 1/4W Resistor.

Passive attenuator is nothing more than a fancy word for a volume knob. It's just a potmeter inbetween the in- and output of the signal. It's called 'passive' because it doesn't require any power source. But by flipping the switch from passive to mix, the signal is now also being led into the mixer and becomes part of the signal coming out of ...

Simple Mixer Schematics PREAMBLE: I've been cooking audio circuits for so long now I no-longer need a recipe. A lot of the theory I have forgotten over the years because I've just gotten to know the circuits by instinct. But this should serve as something of a guide to designing mixers from scratch. The idea:
