Re: Balanced Inputs noisey and hipass filtered

Hi Lukas,

On my boards, value of capacitor C(49, 50, ...) are 1nF. Fc = 7KhZ
Correct value is 1uF (github kicad schematic file)

Passive high-pass filter of balanced input breakout board (6 duals inputs)

Hi, There is a problem with the input passive high pass filter ( C=1uF and R= 47K // 47K ) With the values of components from kicad SCH file (https://github.com/flatmax2/AudioInjector.Octo.balanced/blob/master/AudioInjector.Octo.balanced.sch.pdf) , Fc = 1/(2 x PI x R x C) = +-7Hz https://preview.ibb...
