Hi all,
I need to build an EQ circuit to cut or boost LF and HF in a portable boom box system. A Baxandall EQ will do the trick. The circuits for a stereo signal are obviously two, with the need of stereo potentiometer.
My question is : would be ok to convert the L/R signals with the help of a summing amp into mono and then having just one EQ circuit with mono potentiometer?
How can I then convert the mono signal back to stereo?
Thanks

If only that was possible. No need for stereo interconnects, just do it all in mono and convert back to stereo!!
Just buy one from ebay or Amazon eg:

Well... You could do time multiplexing similar to what was done in the early CD players. But you'll get better performance and lower cost if you just buy stereo pots.
