this is at least audio related DIY, and could have to do with headphones. :) but this is in fact for a MiniDSP / amp active setup.
The miniDSP is only putting out 1v of audio signal. The amp I paired it up with need more line input voltage, maybe like 4v.
I need to put together a basic line-driver circuit, with a already-regulated/filtered 5v of DC current.
Want to use a 4 channel OPA4134, because the miniDSP is a 4 channel device.
I have basic understanding of wiring/building. Have built a couple CMOY head amps, and have modded various electronic over the years.
Can I modify the CMOY design for use as a "line driver"?
