Hi,
I recently bought a x400 card;

I have two questions:

  • How do I set the jumper to connect the RCA outputs to my hi-fi amplifier (rotel ra06)
  • You can advise me of full-range speakers to be connected to the powered outputs?

Thank’s in advance…

Audio output = open
Audio amplifier = short

Why buy that board to deactivate the onboard Amp ???

Do you know if the ST X400 supports mute on start like the iQAudio DigiAmp (github.com/volumio/Volumio2/issues/541)?
