Op amp audio mixer. The op amp inverting amplifier provides an ideal platform for an analogue audio mixer. As shown above the various inputs can be taken via a suitable resistor to the virtual earth point. By using the virtual earth of the inverting amplifier, the level for one input is not dependent upon the conditions for any other input.

4 channel Audio Mixer using a Single Op-Amp. For the first audio maker circuit, we’ll incorporate an IC LM3900. LM3900 is in a 14-pin dual inline package. Then, in the list of LM series, it is a Quadruple Norton Op-Amp IC. Additionally, its supply voltage varies widely from 4.5V to 32V. Also, it has an internal frequency compensation.

Oct 13, 2012. #6. The output impedance of a mixer is usually extremely low. But the input impedance of an amplifier is usually fairly high. When they are connected then there is little voltage loss so the impedances are NEVER matched. The same for the output of a power amplifier, its impedance is very low, 0.04 ohms or less.

The op-amp output voltage is always equal to the voltage drop across R5 and compensates it. Figuratively speaking, it acts as a "negative resistor" with resistance -R5. The result is zero resistance... as though the summing point is connected by a piece of wire to ground... but still there is output voltage at the op-amp output...

The circuit of four channel audio mixer is wired around op-amp IC 741 followed by few other active as well as passive components. The IC 741 as previously mentioned works in inverting mode with extra resistor for every single input channel. When a single audio signal is fed as input in the circuit, it starts working as an inverting amplifier, where R 1 and R 7 are
