HiFiBerry team Hi Cremel,
12V 1A seems to be a bit underpowered. Can you post the full specs of your power supply.
We recommend at least 2A, better 3A.

HiFiBerry team Hi,
have you measured that there are 12V on the Amp? Please check this with a multimeter. Is the polarity correct?
Best regards

CREMEL Stéphane Hi,
Yes the polarity is correct, i have 12V on out of the power, and 12v on in of the Amp+, but i dont know where i can test for more information. -
