Question on Eurorack M/S Encoder

Hey there,
I’m looking for a hardware mid/side encoder to process stereo line signals.
I found this Eurorack module:

LRMSMSLR Mid/Side Encoder-Decoder

I never used Eurorack and I’m confused about the technicalitites, amongst others:

  • Current draw:
    +12V: 15mA
    -12V: 15mA
    +5V: 0mA

Can this be used on a line signal or is this only suited for control voltages in Eurorack modules?
I hope someone could clarify.

Yeah, you’d need something to boost the line levels going in and attenuate the Eurorack levels going out because Eurorack audio levels are quite a bit higher. There are modules to do this easily, but it’s more cost of course.

Adding to that you’d need a little case and some sort of power (say, a 4ms Pod or something) so it probably wouldn’t be the most cost-effective route. Having said that, if you do go in that direction there’s also the Xaoc Minsk and the Joranalogue Enhance 2.

Understood, thank you!
Are there any guitar pedals that can split a stereo signal to mid/side?

Not that I can think of but I’m not a massive pedal buff really! I was trying to figure out if there might be a hack-y way to do it with other stereo pedals but couldn’t come up with anything.

Maybe something like this Radial Engineering box might be the closest in a fairly compact format?

I noticed this device, but I’m not sure if you can revert the signal path to achieve the encoding.
I have a hacky solution already with stereo Impulse Response Pedals. However it needs 3 operations aka 3 pieces of dedicated gear.
First double the stereo signal,
second apply Summing to the first signal pair for the Mid Signal,
third subtraction of the second signal pair for the Side Signal.
That’s too much gear.

Ah yeah, of course there aren’t enough ins and outs there for it to be a one-stop solution.

If you did want to go the Eurorack route something like this Ladik is a fairly cheap way of converting the levels. I think this sum/difference unit might be about your cheapest way of doing the no-frills mid-side and back again conversion.

Add in a small Pod (which I think would have to be an X version to be able to accomodate the module depth) and you should come in reasonably below what that Radial might’ve been, but it’s a faffy solution. I think the smallest X Pod is the 34x though so you’d have a bit of room left to maybe add a cool Eurorack only effect or whatever!

Seems like a thing you might be able to build within a Poly Beebo or an Empress Zoia.
