In figure, thereis an inverse adder,it is a basic audio mixer. But this circuit is rarely used in real audio mixer. Because it can approximate op-amp's work limit, actually we recommend increasing the supply voltage to improve dynamic range. In-phase addercan be realized, but is not recommended. Because the impedance of signal source will affect circuit's gain.
