Hi everybody!
I am trying to add an FX loop to my Marshall Code 25 amp.
After a lot of research I figured out that the sound is passed from the preamp/DSP board to the power amp board as analogic sound on 4 cables.
Two of them are ground, the other two are the left / right signal.
I would like to fit an FX loop as follows:
SEND section:
When two jacks are plugged in the send it should send stereo signal directly from the preamp
When one jack is plugged in the L port it should sum up the L and R channel and send out mono signal.
RETURN section:
When two jacks are present than accept stereo return
When only the L jack is present, than split the signal and feed L and R on the corresponding cables.
I've seen quite a lot of amps being able to do that, but I can't find any schematic.
Any support is welcomed!
Regards,
Matei
