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.
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?
Hello Frank,
Thanks for writing in.
Is it thisitem#200218? https://www.amazon.com/dp/B0716XVR7P
We are sorry this item can’t be connected in series.
Best regards.
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
Ciao Francesco,
Grazie per il tuo business. Per favore, puoi controllare se è questo oggetto? 200074
Come ha mostrato la pagina del prodotto, non ha bisogno di shunt. Ma questo articolo ha la versione 50A, che richiede il collegamento di uno shunt. Quindi lo schema sul retro è comune per due specifiche. Quando è 20A, si prega di ignorare lo shunt.
I migliori saluti,
Hello Francesco,
Thanks for your business. Please can you check if it is this item? https://www.amazon.it/multimetro-voltmetro-monitoraggio-alimentatore-regolabile/dp/B01M3RB88U/ref=sr_1_2?ie=UTF8&qid=1514690369&sr=8-2&keywords=DROK+4.5-100v#200074
As the product page showed, it doesn’t need shunt. But this item has 50A version, which need connecting a shunt. So the diagram on the back side is common for two specifications. When it is 20A, please ignore the shunt.
Best regards,
