When developing Erica Black Series and Pico Series modules, we accumulated quite a know-how on compact and great sounding designs, and
we decided to share some of those with DIY community. And therefore Erica Synths proudly presents – DIY Synth Voice module! It consists of all
essential blocks for versatile monosynth, and is 100% patchable for even more control options. In order to make the module more compact and
reliable in tuning, it has digital/analogue design. VCO and envelope generators/LFOs are digital, other parts are analogue. Digital parts are designed
arround pre-programmed STM controller, which comes with a kit presoldered on a small contoller board. Chain up several Erica Synths
DIY Synth Voice modules and you have a versatile polysynth!

  • Page 12 GUIDE ON ASSEMBLY OF THE ERICA SYNTHS DIY SYNTH VOICE What you get? The Synth Voice kit comes in three versions: 1) Set of 2 PCBs + MCU board + 2xK140UD12 opamps + mechanical parts (PCB connectors and spacers) 2) Set of 2 PCBs + MCU board + 2xK140UD12 opamps + mechanical parts (PCB connectors, spacers) + panel 3) Full kit, so you do not need to worry about ordering parts.
  • Page 13 ASSEMBLY 1. Take precautions with regard to electrostatic discharge (ESD) safety. Handling components should be done in electrostatically safe environment. Use personal and workplace grounding. Any discharge (even a minor one) from body to a component may permanently damage it. 2.
  • Page 14 ASSEMBLY 3. There are optional ferrite beads and capacitors for noise generator power supply filtering in order to prevent possible noise getting into PSU circuit. You may omit those and replace ferrite beads with wire jumpers (leave capacitors unpopulated). As our experiments show, the module works fine with wire jumpers.
  • Page 15 ASSEMBLY 5. Install also ferrite beads and reverse polarity protection diodes. 6. Now, let’s sort ceramic and film capacitors! Capacitors provided with kit look like this: 15 pF 47 pF 150 pF 22 nF 47 nF 68 nF 100 nF...
  • Page 16 ASSEMBLY 7. Populate all cearmic and film capacitors on both PCBs!
  • Page 17 ASSEMBLY 8. Insert and solder IC sockets! Pay attention on the orientation key! 9. Install K140UD12 opamps in the VCF circuit! Pay attention on orientation key – it has to fit one on the silkscreen. Use tweezers to align pins of the ICs. Also solder transistors on both PCBs and voltage reference LM4040! Transistors and voltage reference look similar, therefore follow the silkscreen and make sure, you do not mix up NPN 2N3904 and PNP 2N3906 and LM4040!

  • Page 23 ASSEMBLY 18. Insert jacks and pushbuttons on the Control PCB, but do not 19. Insert 3 toggle switches and LEDs (pay attention on the orientation – follow solder them yet!! the silkscfreen) in relevant places, but do not solder them yet! 20.
  • Page 24 ASSEMBLY 22. Connect all three PCBs! Pay attention on MCU board orientation! 21. Solder male connectors on the small MCU board!
  • Page 25 VCO! ENJOY! CONGRATULATIONS! YOU HAVE COMPLETED ERICA SYNTHS If your module doesn’t work, please check the Erica Synths DIY SYNTH VOICE! Synth Voice build thread on Muffwiggler or contact us on the email Now you can connect the module to PSU, and see, what happens. If you haven’t info@ericasynths.lv!
