Where to read about how to use amp boards?

[bcodemz]

Hi guys,

I want to eventually use an amp board for my active speaker design. I'd like to learn about these amp boards, what they are, how to use them, etc. I'm starting from pretty much 0, and I'd like to get a decent to good understanding of amps.

For example, I'd like to use a 2.1 amp board like this for my 3 way speakers.

12V 50WX2 100W TPA3116D2 2 1 HiFi Digital Subwoofer Amplifier Verst Board | eBay

I'd like to learn how does this amp receive input, say from a miniDSP, where are the terminals to output to the drivers, and where the volume control is.

Thanks

Hi Low,

This Board needs a stereo analog input via a mini jack (on the back end off the board the left jack where stands ´input´on the board). then follows the bass speakers - and +. The inputsignal for the bass speaker is formed out of the stereo signal and are all freqenties under 200Hz so be sure your bass speaker is a really bass speaker and not a bass-mid one. The next are - and + for the Rch and - and + for the Lch speaker or v.v.. then follows the jack to Power supply the board.
