Here is a simple 3 input mic mixer circuit using the popular uA 741 ICs. Four 741s are used here.IC1, IC2, IC3 are used as preamplifiers. They produce a gain of around 40 decibel to the individual input signals. The IC4 is wired as a summing amplifier to add the signals from three preamplifiers.IC4 also gives a gain of around 5decibel to the final output signal.
Simple Microphone (MIC) Amplifier Circuits

The first one is a single transistor simple microphone circuit, very simple to hook up using an electret microphone or MIC and an audio amplifier. Typically the 10K resistor within the microphone's positive port offers this specific vital voltage for the procedure. The capacitor of 100nF on that particular network prevents the DC component of the transmission permitting …

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.
