Audio Circuit Mixer: 5 Ways of Building an Audio Mixer
https://www.wellpcb.com/audio-circuit-mixer.html
Audio Mixer with LF353 circuit . 3 CH MIC preamplifier with Mixer using LM348. You can use a 3-channel microphone amplifier circuit to make a mixer with a microphone. Also, it is cost-effective since you won’t have to use four pieces of IC—741 ICs. Instead, you’ll use a single IC LM348.

To make audio mixer circuit we need amplifier stage and here LM3900 IC is used as amplifier stage. All internal amplifiers are employed to amplify the audio input signals, Each Audio input is controlled by Variable Resistors (VR1 to VR4) and hence we can easily control individual audio channels. Inverting input of Amplifier gets the audio signals and non inverting …

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.

The amplifier uses two 2N3823 FETs (Q1, Q2) and delivers an overall open-circuit gain of 400: The maximum i-f input is 2.5 mV rms before peak clipping takes place in the 1-V rms output. The selectivity of the circuit follows very nearly to that of the filter alone.
