This simple circuit mixes two or more channels into one channel (eg. stereo into mono). The circuit can mix as many or as few channels as you like and consumes very little power. The mixer is shown with two inputs, but you can add as many as you want by just duplicating the "sections" which are clearly visible on the schematic. Parts

The audio mixer has two audio inputs (their number can be increased simply by adding inputs in parallel). For my case two inputs are enough. The device has one audio output (the jack in the middle), which can be used as headphone driver or as Line output and connected to some power amplifier.

Audio power amplifier circuits will be dealt with in a future episode of the series. SIMPLE PRE-AMPS. The basic function of an audio pre-amplifier is that of modifying the input signal characteristics so that they give the level frequency response and nominal 100mV mean output amplitude needed to drive the amplifier's tone-control system.

A mixer can be implemented in several ways, using active or passive techniques. Ideally, to meet the low noise, high linearity objectives of a mixer we need some circuit that implements a polarity-switching function in response to the LO input. Thus, the mixer can be reduced to Figure 4.4, which shows the RF signal being split into in-phase
