Hi, I recently purchased the “Digital Amplifier Board, DROK HiFi Dual Channel Stereo Audio Amplifier DC10-25V Digital 2.0 Power Amp Board 50W+50W Output with Volume Adjustment Knob” from Amazon (https://www.amazon.com/gp/product/B07B4BKTVP) and I have a couple of questions.

1) Is there a manual/wiring diagram for this? I can’t seem to find this specific model on the DROK website.

2) Can anyone tell me what the two white connectors that I circled in the attached photo are used for?

Thanks!

Hello Shane Kirk,

Thanks for writing in and sorry for inconvenience may cause.

Please refer to following wiring diagram. 3P connector is the other audio input. 2p connector can offer 5v output, but max current it can draw is 100mA.

Any more questions, please feel free to contact us directly.

Best regards.

Excellent. Thank you!

Do both inputs require line-level sources? Does the JST connector have different audio characteristics than the 3.5mm connection?

Hello Shane Kirk，

There is no difference between these two ports. You can choose one base on your actual situation.

line-level is Ok. It is not pre-amplifier, so weak electrical signal is not availalbe.

Best regards.
