Mono or Stereo to Stereo Splitter? Yes!

A few days ago an interesting life hack came to my mind. How to convert mono-stereo to stereo signal splitter for headphones, for example?!

The problem was listening to the sound in the headphones from the Doepfer Dark Energy 2 analog synthesizer. The fact is that on simple analog monophonic synthesizers, as usual, there is one monophonic output. Being a fan of passive analog devices, I want to do it in a compact, convenient and small device. Let it be something like a splitter. Thought that the device should support both stereo input and mono! After thinking a little with a sheet of paper and a capillary pen, figuring out the various options, I got the following:

As a result, there are two receiving mono jacks and one stereo output at the input. These are standard connectors with pins for pin detection. These are budget, but high-quality stereo connectors with an additional contact, many of these connectors is in electronic stores, a very common contraption…

Consider the following specific features that this device has.

In the presence of a mono signal that is connected to either of the two input connectors, the signal is distributed along the right and left channels of the headphones, as in the simplest current division circuit (see current divider).
Perhaps you need a stereo signal at the inputs. You can do this using two inputs as a stereo pair! Accordingly, the headphones sound stereo.

It is applicable when you need to send a signal from a module with a mono output to your headphones, as for example with a Ring modulator or a stereo signal pair for example from a Quad Mixer module.

And it comes to deep synthesis, and the time comes for improvisation, immersion in thin moments of the multilayer fats of the German synthesizer…

Thank you very much for your attention!
Let the article be useful and useful!
I wish you good and full cosmic states of mind!..
