I’d like to redirect the output of my piano keyboard to an oscilloscope. My keyboard has an audio jack (1/4") designed for headphones. Is there an easy way to use the audio jack to direct the output to an oscilloscope instead?
I have an audio-jack-to-RCA converter cable, so I was thinking of buying a RCA-to-BNC adapter and doing it that way. Would that work?
PS When replying, please don’t assume I know anything about audio electronics–I’m a theoretical physicist, not an engineer. Thanks!
That should work fine.
Most keyboards will shut off the speakers when you plug the headphone jack in. Do you need to be able to hear what you are playing or do you just want to see the waveforms it makes on a scope?
My keyboard doesn’t have built-in speakers, so I don’t expect to be able to hear anything. I’d be happy to just see the waveform.
Although if there WAS a way to hear the sound, too, that would be really awesome.
hook up a Y cable (splitter) to the headphone jack, plug headphones in one and the scope in the other.
