Hi,

I bought a DROK TDA8920 Subwoofer Stereo AudioDigital home amplifier 140W but I am not clear on the type of power supply Required for it to be powered. I have been searching so that I can buy online a power supply with +\- 20V to +\- 25V (DC Dual) output but I cannot find anything.

To be safe, I think I need help.

Please could you point me in the right direction. What type of power supply should I buy for DROK TDA8920 Subwoofer Stereo AudioDigital home amplifier?

Regards

Maziva

Can you give an example of this power supply that give +\- 20V to +\- 25V with positive and negative dual supply.

I am thinking of buying this one: 24V Mains AC-DC Power Supply Adapter UK for Dymo TESA2-2401000 P/N:924883

http://www.amazon.co.uk/Mains-AC-DC-Supply-Adapter-TESA2-2401000/dp/B00LY6XU5Q

Is this the correct one? Does it work?

Please could you give basic example.

Hello Maziva,
Thank you for writing in.
The power supply you are thinking to buy is NOT suitable for this product.
Here is some reference examples for you:
AC 110/220V DC 24V 5A Regulated Double Output Switch Power Supply
AC 110V/220V to DC 24V 15A 360W Voltage Transformer Switch Power Supply for Led Strip
The power supply which has 200W output power will be better.
Hope this will be helpful to you.
Best regards
