From the project
Active audio signal splitter to drive multiple parallel stompboxes
This project is about an active audio signal splitter that utilizes the TL074 opamp to drive multiple parallel stompboxes.
- Split one line-level input into three outputs - Direct output (unity from input buffer) - Stompbox output 1 (level pot + output buffer) - Stompbox output 2 (level pot + output buffer)
- Recommended 18 V - Should work at 12 V - May work at 9 V - Series schottky protection included
