## [Blattwerk - Betula](https://github.com/Cs4System/Eurorack/tree/main/Betula)
- 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: -110dB
- 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)
## [Blattwerk - Salix](https://github.com/Cs4System/Eurorack/tree/main/Salix)
- VCF based on the Moog Transistor Ladder Filter
- Compensation for loss of bass in high resonance settings via potentiometer
- 6,12,18,24 dB/Oct selectable via potentiometer or CV!
- 2 Inputs with attenuator for audio and CV
- Seperate V/Oct input.
- Input-Drive indicator LED
- 8HP
- small and dense SMD build (0603, SOIC, SOT-363!) Not a beginner build, please be sure to have some SMD-soldering practice!
- 45mA @ +12V and 25mA @ -12V
- quick demo: https://youtu.be/XMdGtwIK5IQ
