You got it! 🙂 You can put the L&R grounds on their respective pads instead of the same one if you want. It's all the same, but you may like them on separate pads.
You can do that for any of the inputs. Whichever one is most convenient.

Success! Its playing sweet, clear music.
Thank you ZM, Nelson, IAIMH and everyone at the DIY Store who made this possible.

Hi together,
This is a documentation for the software of my module with input control in balanced version. This module can also be used for completely unbalanced preamplifiers. Mixed operation is also possible.

There will be a module for the Iron Pre that is designed exactly for its hardware. I will include the power supply of the Iron Pre.
The existing input board is shortened so that only the output sockets (maximum 4 mixed outputs) and the two Muses chips are available here.
The microcontroller board contains the IR sensor, connection for the 2.6 inch display and the rotary encoder. It is able to control a trigger output and a power output (1600VA). In addition, a standby mode is possible, which enables switching on and off by remote control.
The special Iron Pre solution works on all existing boards and also on the newly designed boards. The existing boards only need to be wired and populated slightly differently.
I am currently expanding my website with the description of the existing module. There will be a separate entry for the Iron Pre. I will post the link here when I have started to expand the website.

I also offer pure volume controls without input selection (with or without display). If you only want to replace the volume control, you can also get a customised solution.
Please do not orientate yourself on the prices on my website.
The Iron Pre solution will be cheaper because part of the hardware is already available. There is a discount on ready-made solutions if you point out that you belong to the forum.

If you have any suggestions or questions, please do not hesitate to contact me. I am watching both posts and will try to answer them quickly.
first impressions
It is an add-on board that is soldered directly into the pads for volume control.
The resistors are assembled alternatively; either SMD (Susumu) or CMF55. Since there are already 330Ohm resistors in the input signal path of the Iron Pre, these resistors can probably be dispensed with.

@frankwilker this is exactly what I was planning to make by myself (or try to make...) after summer vacation. Very happy to see you are going in the same direction.
I'll for sure join your project when available.

I look forward to this as well as I'd already began studying how to add a Muses volume control solution.
Hi Frank, looks great. I'm putting together the components to start building my kit, balanced, and I'm counting on your solution for volume control🙂
