Hi, I nead a simple fast schematic for turning stereo sound into mono sound, and if possible back to stereo. Thanks.
Code: L-||--2.2k resistor---+ | +----Mono | R-||--2.2k resistor---+ Cheap & cheerful, the caps remove any DC offset on the outputs and may not be needed. Use 220n-2uF. Resistor size isn't critical. Better way is an opamp summer circuit. The thread's all of half a screen down.
Just use the left channel? Thats the most common way to do it simply. Typically it works fine, unless you are listening to something like "yellow submarine" by the Beetles
