The easy circuit mixes 2 or more input channels into one channel (eg. stereo to mono).
The circuit must as many or as few input channels as you like and consumes very little energy mix.
The mixer is shown with two inputs, but you can only add as much as you want simply by repeating the “sections” that are clearly visible on the plan.
Electrical Part Component
R1, R3 10K Pot
R2, R4 100K 4.1 W resistor
R5 6.8K 4.1 W resistor
C1, C2, C3 0.1 uF capacitor
Q1 2N3819 Junction FET
MISC Wire, Shielded (Metal) Case, Phono or other connectors for power
Note
1- Many or as few channels needed to be added to the mixer. Do this simply by repeating the command “sections” are clearly indicated on the chart. A version of this mixer I saw had 25 entries!
2- A shielded case is probably necessary to prevent disturbances and vibrations.
3- The circuit can be powered by a 9-volt battery.
