Hello to all DIY Audio Hobbyist

I' m Spiri from AKOUO Audio Solutions and want to introduce our new company for DIY audio modules here.

We produce small audio modules at reasonable prices, to enable any DIY Audio Hobbiest the use some digitally controlled chips.
That is why we are here in the forum .
This forum has many bright minds, discussions on high technical level and the handling is very polite.

And of course we want to sell our modules.

Most of our products need a micro controller and we constantly expand our software.
This is also why we offered a programmer.

Our first 20 boards with the volume control Muses 72320 and the associated controller are done.

Visit us at Willkommen bei AKOUO

and please share your opinion about our products.

Have Fun and DIY

Hello spiri,
I came here while I was looking for a passive control volume... so this GB is really interesting!
I'm quite a "noob" in DIY, so I hope Im not confusing.
So, for 4 inputs, I'd need:

1 Controller MINI
1 Modular Volume
1 Rotary Encoder (volume and selection)

Am I right? I saw this pics on your site:

An externally hosted image should be here but it was not working when we last tested it.


But I thought you were using 2 controllers for 2 balaced in ( I wan to go for a single ended).

Thanks in advance!

EDIT: I'm sorry... as usual, I've asked before searching on documentation. 🙁 Page 8 here: http://www.akouo.at/akouo/downloads/volume-select-datasheet-en.pdf :

• 1 x AKOUO Select & Volume
• 1 x AKOUO Controller Board with Software
• 1 x AKOUO Power M1 Supply
• 3 x Flat cable set
• 1 x Transformer 2x18V
• 1 x Transformer 1x6V
Click to expand...
So the encoder is in the Controller board, right?

spiri, when will this GB end? 😉 I have to decide if I'll use a Hot Rodded DCB1...

You are right. Picture shows the volume and select.
If you build a preamp, this is the right solution.

If you only need a pot, the mini version the best solution.
We will also prepare the software to switch input relays with additional pins on the mini controller.

I have to get the MINI Boards in the Shop and then the GB runs about 2 weeks.
Stay tuned!

The B1 with dual supply or a Joachim Gerhard filter buffer without the filter, as it is offered by EUVL in a GB, fits perfectly.
I think of something like that as pluggable add on board for the MINI Series.

Yes, my goal is to build a nice preamp, not aiming to highend since I'm very noob. Unfortunately I'll have to fit all in a GX283 box (23x21cm).
I admit that 4 inputs are quite too much for me, but as my grandmother used to say "to have it enough, you sometimes need to have some more to spare.
I'm building the Salas HotRodded DBC1, I think I can share the same dual toroid (but I didn't check it still).
As soon I get more info about the buffer, I'll PM you. 😉

If the mini version will also control input relays (through push function on the digital encoder pot - I assume) I will sign up for 2 balanced stereo sets (4 mini muses boards and 2 controller boards).
