Here's a simple 2 channel audio mixer:
R
C +------/\/\/\/\---+
|| R | |
V1 --||---/\/\/\/\----------+ | |\ Vcc |
|| | | | \ | |
+--+----|- \| |
C | | \ |
|| R | | \ |
V2 --||---/\/\/\/\----------+ | \______|_______ Vo = -(V1+V2)
|| | /
| /
| /
+----|+ /|
| | / |
| |/ Vee
GND
The values of the components can be
R= 47k ( good choice for audio applications )
C= 0.1uF
Vcc= -Vee= 9 V.
Op Amp 741 for low to medium performance audio applications.
Any other low noise type can be used for
higher performance/fidelity.
