LS60 wireless Internal amplifier disassembly

[wencheng]

I got the LS60 wireless amplifier from the thrift market, based on electronic crossover, HF-AB100W, MF-D100W, LF-D500W.
All the features have been fixed so far, I connected this amplifier to some extra speakers, and the sound I got was great.
、
some pictures：DSP-ADAU1451/ADAU1452、interface-PCM9211、MCU-STM32F109/STM32F401、DAC-WM8470
Connections speakers - wisa-SUMMIT ，CPU+WIFI- AMLOGIC A113X

When I have time, I'll update the picture,

this is really interesting . how so you go about figuring which part is which ? by starting with the bits you can tell by the naked eye then what?
so did you get a pair or just one to make only make one speaker ?

I'm so sorry
To make it difficult for you to see clearly, I'll put away this post for the time being, and post it when I have time to edit it.
Thank you

Extremely cool. Thanks for posting.

So three different internal amplifiers, two IRF driven class Ds and one Class AB, all on PCIe style edge connectors.
