I have put together the Chaney Sound Organ (http://www.electronickitsbychaneyelectronics.com/prodinfo.asp?number=C7025) and replaced the microphone input with a rca plug.
I tested this with a sansa audio player (battery operated) and it worked fine.
However, when I use a splitter with the audio player -- and have the other side of the splitter going to an amplifier, I trip the reset in the power strip that is powering both the amplifier and the sound organ. Is this some sort of ground loop, or some sort of feedback? And if so, do I isolate the two systems?
Thanks in advance
