Hi there,
do you sell a ready-to-plug dual ac to dc power supply perfectly suitable for this piece?
Can you provide a link and a wiring scheme to clarify connections between power supply and amp?

Hope you can understand.

Hi – I have a DROK® TDA8920 Subwoofer Stereo/Audio Digital Home Amplifier 140W Power AMP Module. I am selecting a power supply to run the unit. Can you advise me how much current each of the 24v dc rails (positive and negative) needs to supply please?

The product link is: https://www.amazon.co.uk/gp/product/B00HJKT366/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

All I need to know is the maximum current consumption by each of the dc power rails (+ & – 20-24v dc). Then I can make sure I buy a suitable dual rail supply. Many thanks

Hello Philip Benton,
It’s better the current is over 4A.The voltage must be in the range of operation voltage.
Best regards.

Hello Roberto,
Thanks for writing in.
Do you mean connect pre-amplified subwoofer output to the signal input terminal of our item? But there is only one input terminal, we can’t ensure the left or right you mean. If you can, please let us know more detail.
Best regards.

The headphone output can not be used because it blocks the output signal to the speakers. You can use the amplified (high level) outputs, but I do not think the card supports this kind of signal, right?

So I think the only audio signal I can use to drive my subwoofer (homebuilt) through your card is the hi-fi pre-amp (subwoofer) output. Since the signal is mono (RCA), how do I connect it to the card? I hope i was clear.

Thanks
