Hey folks I am working on a mixer for a modular-esque synth that uses a combo of Teensy audio library and a 40106 based oscillator.
The chip oscillator comes in pretty hot (im using a 5v power supply) compared to the teensy, which is fine but in playing around with resistors and potentiometers I realize that I do not know what the target signal strength should be for consumer-grade PA line level signal. The research I have done keeps coming back to impendence. Which still does not make any sense to me, if impedance is the AC equivalent of resistance then how can there be such thing as an output impedance? That seems to me like saying how many ohms a battery is. What makes more sense is peak-to-peak voltage range (which I can see on the O-scope).
Can anyone provide some guidance on what sort of voltage ranges I should be targeting? Anything that would help me relate that to impedance would be great to just so I am smarter tomorrow then I am today.
Thanks!!
