Hello ..
I was modifying a karaoke pcb, in attempt to fix microphonics , when part of pcb was touched/tapped it produced sound in speakers, this circuit used JRC 4580 op-amp and PT2339 for echo.
when reading PT2339 datasheet got this idea to add circuit for Auto double track (sound like two people singing). Searched internet found some article on phase shifter.
My question is it practical to use op-amp phase shifter to achive Audo double track effect, if some had tried please share your points.
Thank You

Mods. Please change topic heading to Design Idea: Auto double track pre-amp circuit
As this discussion is not about acutal premap circuit.
