Hello everybody , i have problems with the phono stage of mine devialet 400.
the problem is that the sound is terrible.When i turn on the phono stage you can hear a hard hiss of sound , is this normal?greetings hans
I would say that everything below 1mV produces a lot of hum. If you are using a low output mc, perhaps you should use a stepup transformer?
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,

It seems a little strange. I have 2.1mV and the phono stage is very quiet. What are your settings?
I use an Ortofon Quitet Black (0.3mV) and the hiss level is quite acceptable.
thank you all for your reaction ! i will look for the settings , specially if the wifi is on or off when the phono stage is working,greetings hans
Hello everybody , so , now i maked a new configuration just like Jean-marie said.The wifi must now turn off when the phonostage is working. To bad...
i can still hear a bad noise from the phonotrap without using the phono!! Who have the solution for my problem? greetings Hans from Hoek van Holland the netherlands
Have you been in to RAM, via the remote, and tried experimenting?
What happens when you disconnect the phono leads from the TT? The stage should be very quiet with MM.
Like @
Soniclife is proposing, I would recommend to progress step by step:
1) Is the phono entry noisy when nothing is connected to it?
2) Is it noisy when only the cable is connected to it?
3) Is it noisy when it is connected to the turn table but without the cartridge connected
4) with the cartridge connected
That should give an indication of where the problem resides.
Best of luck to tackle the culprit,
Jean-Marie
