[IN STOCK] NEW L-1 Stereo Mixers

Post by L-1 »

I made new stereo mixers to mix my system properly.

Several stereo mixers can be mixed into Unity Stereo Mixer as pictured:

Two 2 Channel Stereo Mixers can be controlled from the Mute expander via splitted cable:

This looks super useful! I have a lot of stereo sources and mixing them down is a pain.

For the unity mixer, are the Left inputs normalled to the Right inputs for occasional mono sources?

No. The Unity mixer is planned as mixing node and required input modules like this Two Channel Stereo Mixer, it has normalled inputs for mono sources.

bit off topic but:
- what kind of clips do you use in the first picture to bundle your leads?
- are the cables custom made?
i recognised the rean plugs which i also use for my custom cables
(with sommer cable onyx 2025)
- how did you do that colour coding? i'd like to adapt that solution.

i'll probably will have more questions concerning the actual topic,
but not before i thoroughly researched all the information that
you have given so far...

till then, let me say this: i am a really happy user of the vc stereo mixer
and i am glad to see the things on the new one that i had to solve
externally, i.e. cv-attenuation and aux send...

once again, great desgin!

- Thse clips left from tuners.

- yes, the cables made by L-1. I cutted some audio cables with RCA plugs to have this nice thin grey cable. Color coding is made with shrink tubes.

- also separate left and right inputs.

What would be the best way to use the 2 Channel Stereo Mixer as a stereo send/return effects? I have two stereo signals that I'd like to mix together and control the send per stereo channel.

Also, is there way to achieve PFL like functionality with the Phones module?

Yes, it's possible - stereo send/return.

You can feed your stereo signal into Phones module from any point of your patch. There are multiples for using a signal further.

Where can one get the A50K Dual gang pots for the 2 Channel Stereo Mixer? (Part number P1, P2 - SEND1, SEND2).
Smallbear, Tayda, Thonk, etc don't have them.

You late. Thonk had them. I hope they will make new stock.

When you will be ready to order kit, write me, I will try to find a couple for you.

(EDIT) Thonk has dual 50K linear. They will fit ok.

I PM'd L-1
but i'll ask here as well:
Does the pcb come with all SMD parts already on the board? It seems to be the case from the pics in the OP.

Got another question about the Stereo Unity Mixer for you, L-1.

Are the two outputs on ether side summed? Why the double output? Sorry if it was explained elsewhere. I must've missed it :/

Two outputs are just multiples.
I planed for example one out for speakers , another for recording.

How's the panning work on the stereo mixers? I mean, you pan mono sources into a stereo bus. I'm confused :hmm:

Also would be great with a 4hp version of your unity mixer (don't need the leds)

Level meter is needed to control sum level because easy to overload with many summed channels.

How panning works - at the picture yellow one channel, green another. Panorama is modulated by triangle LFO. It has -4.5dB at the center according to the panning law.

Okay, but how does panning work on stereo signals? You pan two mono signals left and right, so why is there a pan control on each of the stereo channels?

Pan is an attenuator for each channel. So if you pan hard right there is no left signal in the output, and the right output is amplified relative to central pan.
