  1. I just received this unit in preparation for a gathering… but it doesn’t work… bought the suggested power supply, which lights it up, but tried two sets of speakers and a good IPhone input and I get no sound out of it. Speakers don’t seam as thought they are getting anything from the unit, like a bump of sound when plugged in or when unit is turned on.

    DROK Digital Audio Amplifier, Home HiFi Stereo Amplifier Subwoofer 150W+75Wx2 High Power 2.1 Channel Class D Bass Amp, DC 18-32V Input Voltage, TAS5613 Amplifier Chip

    kinda bummed as I guess I’ll have to use my 15 year old receiver when I thought this little unit would do the job.

    Any suggestions before I return as not working to Amazon this afternoon?

    • Hello Barry Strand,
      We are sorry to hear that.
      Would you please tell us more details about your operating parameters? For example, input voltage/current, speaker power?
      With more information, we can find out solution more quickly.
      Best regards.

  2. You have this DROK AC-DC adjustable power converter AC 110-220V to DC 0-48V, 480W. We would like to put three of this in series to achieve 120VDC.
    Current wise @ 120VDC – we need only 5A. Do you think this set up would work?

  3. Ho acquistato drokDc4.5-100V20A.guardare lo schema nel PC non era menzionato nessun shunt.ora nello schema del dispositivo fa vedere uno shunt.poi scusate ma 2 righe in italiano non erano utili per spiegare perchè non fornito.ora come lo uso senza questo shunt. Lo devo acquistare a parte? Grazie per una risposta
