Good...day...Gentlemen, Ladies.
I have encountered a troubling aspect in my audio project. A balanced line's filter and the reflected impedance from the amplifier (it's the reflected Z throwing me off).
I would like to use a 1st order highpass filter (fc=30Hz)
Ctotal=110nF
Rtotal=48.2kOhm
C1=C2=220nF and Rtotal is RIN to amplifier and all.
I am used to seeing R parallel to L but if R is suitable, can't I omitt R for Rreflect?
Thanks in advance,
