LepaiLP-2020TI Digital Hi-Fi Audio Mini Class D Stereo Amplifier with Power Supply

LepaiLP-2020TI Digital Hi-Fi Audio Mini Class D Stereo Amplifier with Power Supply

Q: Using this am to power 2 external speakers. ok to keep the power on even when the tv is not?

Yes, it would be fine to leave it on. The power draw would be almost negligible. I have older versions of this amp (with the Tripath chip vs TI), and have had one going 24/7 for the past couple years in my kitchen.

Q: Is this 2 x 10watts or 2x 20?

Power supply specification is 12 V , 3A. 12V x 3A = 36 Watts. So you are not going to get 20 watts per channel (40 total) even if the amp was 100% efficient, which it isn't.

Q: Will this amp work with the polk audio psw505?

Yes it will work with the psw505. I have mine running through a Sony SAS9 10" powered sub to my Sony 6 1/2" bookshelf speakers and it sounds awesome. You will need to connect the amp speaker wires to your polk sub 'speaker in' inputs and then wire the 'speaker out' to the speakers you are using.
