My first electronic project - to build a 3-way active XO.
- I got & studied schematic for both powersupply & XO. OK.
- I got op amps (OPA2134)
Can I ask stupid questions?
- What are orange drop caps? (I found them at Apex Jr for cheap & in values I want, appx 33nF) Are they suitable for this app? Can you recommend other capacitors & source?
- I'm thinking of using registor array / network to allow me to play with different XO frequencies. They're 2% tolerance, 14-DIP package (7 registors) sold at Digi-key & Mouser. Any problem using them?
- How should I connect the ground from the power supply? to signal ground? not connected?
Thanks,
Duc
