Hifiberry and Supstronics X 400

Hi everybody,

i have tested two ampli with my Raspberry B+.

Hifiberry amp+. hifiberry.com/ampplus/
Supstronics X 400. dx.com/fr/p/supstronics-x400 … gU2Po0cQ5s

Hifiberry = Perfect. 2x 25W
Price= 49,95$ without shipping
Sound : Good

Supstronics X400 = good. 2x20W
Problem with the box and the height capacitors. Benefice: IR receiver, volume adjust in the board,
Price=34,11$ with shipping
Sound: Good

I have 2 Suptronics X400 and 8 Hifiberry with enclosures DIN :slight_smile:

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 ???

for testing with my stereo amp

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