I want to make inline attenuators for my Modi/Vali stack as there is channel imbalance below 8:00 and my max listening volume is 9:00 with either gain setting.
I don't know if I should use an L or Pi network, and don't really understand how to match resistors to impedances or why direction/location matters here. I tried a couple different online calcs and some say to use two resistor values (R1 + (2x) R2 ) and others say to use three values (R1 + R2 + R3).
Modi output = 75 ohm
Vali input = 50k ohm
Attenuation: calcs say 35dB is minimum I can do? The pre-made inline attenuators come in 12dB and supposedly work OK for this stack. I might prefer closer to 24dB.
Any help is appreciated. Thank you.
