Module Idea - Zero HP Passive Stereo Panner

I've got a few mixers now, I've got CV-able Mono mixing that I can pan with voltage and mono-to-stereo panning mixers, and I've got Stereo mixers.
What I always want to do with stereo sources is to Pan the stereo slightly and it seems to me there are a bunch of No-hp modules around but what I want is a Zero HP Passive Stereo Panner to connect between a Stereo source and my main mixing.

I don't know if this is even possible.

Thoughts???

Hi Wishbonebrewery,

I am not fully sure what you mean with no-HP modules, meaning you want an external solution? If that's what you mean, nothing pops up in my mind.

If you don't mind to consider a Eurorack module, then Make Noise - X-Pan module comes to mind but that's it, I think, not too many options out there.

Good luck for the search of this solution, please let me know if you found something, I also might want something into that direction and kind regards, Garfield.

@wishbonebrewery What do you mean with Zero HP?
Similar to a passive "inline attenuator" like that?

I have to admit that I too was scratching my head when I read 'Zero HP'. But I did a search and finally found at least the cables.
Hmm, you'll have to make some sacrifices: https://hifi-solution.com/en/speaker-cable/1471-dragon-zero-hp.html

Now you still have to find the module, but frankly, all this worries me a bit.

Exactly like that. @modular01
And I guess I could use 2x Attenuators per Stereo Pair to adjust, but isn't there something called Panning Law https://samplecraze.com/tutorials/the-pan-law/ and the way Panning should work versus just attenuating a split Stereo signal.

From what I can see, there's not really a cost effective module out there to handle the panning.
Though if someone made a 4-6hp module with 3-4 Stereo Panning channels it would be pretty handy.

There's a few here - https://www.thonk.co.uk/product-category/hp-size/0hp/
And here - https://pushermanproductions.com/?s=workmate&post_type=product

But nothing Stereo.

At an affordable price (I have one ;) and it works well :) there is also this: https://www.dv247.com/en_GB/GBP/Koma-Elektronik-Attenuator-Cable/art-SYN0004623-000

i wasnt't aware of the "Panning Law" which totally makes sense...

I found this passive stereo solution. But i assume the Panning Law is not respected:

it shouldn't be that hard to solder short cables with jacks of your choice onto this PCB...

Someone somewhere will make a Stereo one at some point.

An interesting article around these topics:

What a thread!

Interesting :)

In conclusion the A-138s could be one of the best tools for ‘real’ stereo panning and / or stereo balance adjustment, ‘to connect between a stereo source and the main mixing’. And as it seems that you have two (If I refer to your Percussion Row. I have only one but I don't blame you :)) we end up with a great additional... ‘Zero HP'.

Easter really is a beautiful day!

A-138s are handy but only input mono signals, though i guess you could use 2 channels panned left & right then the Volume of each channel as Pan.

Yes, exactly. You can think of the 4 mono channels as 2 stereo processing tools, each one in order to get a control on ‘real’ stereo panning and / or stereo balance.
Ex: Morphagene left out > A-138s in1 / Morphagene right out > A-138s in2
Or: Monsoon left out > A-138s in1 / Monsoon right out > A-138s in2

Because you need the stereo image of a sample in Morphagene or that of the reverb from Monsoon to be better positioned in the song, or it can also be too wide. So, apart from controlling the stereo image for artistic purposes, you can use it to get a good (or better) phase correlation. The more you reduce the gap (in other words, the more you tend towards mono), the less you get problems of phase cancellation, especially with the bass spectrum.

(This phenomenon does not occur in headphones because the left-right sound distribution is necessarily separated, but it can dramatically happen in the case of monitor diffusion. The vibrations of the left and right loudspeakers cancelling each other out... and parts of the song sag or disappear!)

I'll give it a go, though I normally have both A-138s taken over by Percussion mixing duties.
