The full output of the mixer circuit is Vout = -Rf(V1/R1 + V2/R2 + V3/R3 . . . + Vn/Rn). Thus, by making RF larger the gain can be increased. The other option is to make the resistor in the channel(s) smaller, but you are already using a potentiometer that can become very small, thus increasing the size of Rf is a better choice.

In this project, we will build an audio mixer, which is a device that can add different audio signals together into one output. For example, say, one audio input is a cappella, with a person’s lone voice singing and another audio signal is background music. With an audio mixer, you can combine the background music with the singing to have an output as if both audio signals …

To make this a stereo mixer, simply duplicate the circuit for the other channel. They can share the same power supply. We want the input impedance presented to each input to be constant and not a function of the gain setting. So here, the input impedance will be 47k to match most audio sources and dynamic microphones.

In this tutorial, we will show how to build an analog audio mixer using common electronics components, such as resistors, capacitors, potentiometers and operational amplifiers (Op-Amps). We will demonstrate a modular design so that the constructor can decide how many inputs should be provided.

To make this audio mixer, you will need: 2x 10k Potentiometers. 2x 1k Resistors. 2x Momentary switches or pushbuttons (the pic has only one because the other was being used) 2x TRS 3.5 mm audio jacks (you can find these in old mp3 players). Several female to male and male to male wires. 1x Breadboard
