Op amp Adder circuits

The picture is a summing inverter , he is a basic audio mixer . However, very little of the circuit for real audio mixer . Because it limits approaching the work of the op amp , in fact, we recommend ways to improve the supply voltage to increase the dynamic range.

Instruments used can be achieved with the additive , but is not recommended . Because the signal source impedance will affect the gain of the circuit .
