The minus sign indicates that the summing output is inverted (or otherwise phase shifted by 180 degrees). In that case the circuit becomes nothing more than an adder. Rn and also the feedback resistor, Rf have the same value, then the voltage gain for each input channel becomes equal to the unity and the formula becomes:

Its output voltage Uo is given by the formula:ДЄx is the voltage gain for the xth input and it is equal to Rf/Rx. It consists of an operational amplifier, n input resistors (R1, R2 вЂ¦ Rn) and a feedback resistor (Rf).ДЄ summing amplifier sums several (weighted) voltages. This circuit is also known as the summing amplifier. Ok, letвЂ™s start! The heart of the mixing console is the summing circuit shown in figure 1. After reading this tutorial, you will be ready to build your own analog mixing console at a minimal cost. We will also discuss about adding a VU meter. In other words, we will add circuits for attenuating or boosting a range of frequencies e.g., bass, midrange, and treble on each audio channel and we will also add a general graphic equalizer to perform general equalization control at the output. Later, we will add some circuits for audio equalization. The basic mixer will be able to combine those signals from different signal sources, change the volumes of each input channel, as well as the overall volume of the mixer output.

The input audio signals could be anything from microphone inputs, to an audio output of a cd player, to an output of a PC sound card or any other type of analog audio sources. We will demonstrate a modular design so that the constructor can decide how many inputs should be provided.

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). Digital mixing consoles use Digital Signal Processing concepts and analog mixers are usually based on op-amps electronic circuits.

Audio mixers can be analog or digital type. The modified audio signals are summed to produce some combined output signals.

An audio mixer, also called a mixing console, is an electronic device for combining, and modifying audio signals.
