Thanks Vitaly for the files. One more quick question, looking at the first post I see the amp is rated at 100-265vac which I presume that without any kind of jumper or anything else I can power up the amp using my 220-240VAC. Can you please confirm on the same?
Also I see a single standalone spade connector next to the fuse socket, what is that meant for? For the power I see 2 spade connectors beside the fuse for neutral/phase which goes to the wall socket. Do you have a connection from the IEC earth to the amp module?
Regarding the input signal wiring I see in one of your pics but would like to know from you which of the 3 pins belongs to signal/ground for left/right channels? I am going to use a single ended RCA signal as input and not balanced.
The same kind of confusion with the output spade connectors and I see there are 4 and in one of the pic I see your wiring but would like to know from you the connections as well as the right/left outputs.
Thanks

Sure I am waiting for Vitaly to provide some details otherwise need to see other build pics for the wiring connections. I could figure out the input signal wiring for unbalanced but still need to figure out the output connections for left/right.
I have an earlier all-in-one board and the outputs are as in the attached photo. Black wires are Common while blue/yellow are the + leads with L & R marked on the board. “+” outputs go to a speaker protection board in my build. Hope this helps,

Thanks Pete, the connections seems to be similar to my new green board. I will follow the same and check it out. Also in my last conversation Vitaly said not required to use a speaker protection module as its built-in but not sure as I don't see any relays on board. Then I need to figure out how to power the protection module.
Thanks
Thanks
Thanks zek, interesting I will wait for Vitaly to comment on the usage of the protection module in the newer version of the amp that he sent me in green pcb. I remember he told somewhere in the thread like the protection is in-built on the amp itself and does not need to have another one.

If you’re addressing the silver/metallic IEC box in the upper left, I just blindly use those as part of most common builds to filter the incoming AC (if room permits).

You can tap into the +/- 15VDC out line Vitaly put on the board if your SP module (specifically the voltage necessary to operate the relays) can use 15V or less or use a small, separate AC transformer (like I did) since my SP module has rectification as part of its circuitry. I used it because a got a bit of thump when I would turn the amp on. Vitaly didn’t tell me if there was any sort of SP module was built-in with my early version of his amp. If you get no thump when powering on/off then you may not want to use one. I’m presuming the LC output filter negates any concerns of DC output to the speakers?
