phono stage

[Jean-Marie]

thanks for you reaction , i have a mm element and don't now what to do but i hate the sound, i have already buy a project phone amplifier but i just want that the devialet will works probability

Did you check, if you have WiFi activated on your 400 that in the settings of the photo input you have selected ‘Auto WiFi Standby’?

I don’t know if it is your problem, but WiFi is known to sometimes send noise into the phono inputs, hence the option. 

Cheers and best of luck to find the solution,

Jean-Marie
