LAST UPDATE: 2006-04-10
This is a "Signal Detecting Auto Power-On Unit" as in Rod
Elliotts project 38. It is used to automatically turn on my subamp and EQ
I have only changed some minor things from Rod's circuit : R4 to 500 Ohms to make the circuit more sensitive Added a two colored LED and a switch to discharge C4 A IRFZ22. instead of MTP3055 .
The box is an old modem just like my Sub EQ
