Hello DIY-folks,
This is the announcement for a new module and a new "brand"-name* under which I will continue to release my modules.
It will be released on my GitHub:
Blattwerk - Betula
I secretly developed over the last 2 two years, I needed 5 prototypes and a lot of time!
So I hope you all are as happy to see this module being releases, as I am!
The module is now a working prototype. I have two of them in my setup and tested them for the last 6 months.
Features:
All files are available on GitHub, including detailed build instructions.
Please let me know in case you attempt building the module, I would love to hear your experiences and improve based on that feedback!
It is a difficult build with 4 PCBs!!
Feedback!
That's the most important part to me:
The module is not perfect yet. Some channels show more noise than others. Still very usable, but not as quiet as it could be.
The inferior noise performance is most likely linked to the dens PCB layout and the noise pollution of DC/DC converters and so on.
This is the noise floor directly measured in my DAW:Is there anything, I overlooked?
What could help the SNR of channel 5,6 and especially of Channel 8? A 4-layer PCB?
Is this frequency response (roundtrip) ok? (-2.7dB@20kHz)Is there room for improvement on anything else?
*Blattwerk is German and loosly means "leafs on a tree" or "foliage"
The Panel shows a birch leaf. The Latin name for Birch is Betula

The module is now a working prototype. I have two of them in my setup and tested them for the last 6 months.
Features:
- 8 channels In/Out ADAT Interface
- Outputs are DC coupled
- Inputs can be switched with jumpers between AC and DC coupling (In 2 groups: channel 1-4 and channel 5-8)
- Low noise: -100dB
- Low THD: >0.01% @ 1kHz, -6dB(+-5Vpp)
- 22kOhm input-impedance, 1kOhm output-impedance
- 8HP
- All channels with bicolored indicator LED
- ADAT sync indicator LED
- No μController, no programming required, hardware only
- CC BY-NC-SA 4.0 DO NOT USE COMMERCIALY!
- small and dense SMD build (0603,TSSOP)
- 180mA @ +12V and 100mA @ -12V
(Without connected ADTA-signal:
14mA @ +12V and 0mA @ -12V)
All files are available on GitHub, including detailed build instructions.
