Oh, it's just crossed my mind that the component values on the schematic may be wrong or missing. I never put them in properly as it was for my use only, and I knew what they were! If you have any doubts, look at the datasheet.

Tanks a lot for this contribution.
I try to make a pcb and you made it... it's good for me... lol
But you have the same schematic of peter daniel here ?

So with your pcb can I made parallel or stereo or bridged confguration?
And have you insert a mute circuit? what's that? another input on the pcb?

thanks you for a answer

regards,

aceditnanar

Mine is designed for dual mono. It's that way, 'cos that's what I needed!

The schematic may look like Peter's, but has none of the optional other components for different configurations. You could bridge/parallel it if you wanted, but there are better PCB designs for that. Then again, you could just alter the Eagle files to do whatever you you wish.

All the info on the muting is on the datasheet, you have read it, haven't you?

thank you for this quick answer...

I suppose that the mute circuit is just a voltage with a resistance (? ohm?)? and a switch?

You thinks that there are better PCBs for the bridge and parallel? the PCB of peter daniel make all mode, haven't it? and not your PCB?



Sorry for my english..

regards,

aceditnanar

My PCB was designed by me for a specific job. It was never supposed to be universal, and I just posted it here in case it was useful to anyone else. I have no intentions of spending more time changing it, but if anyone else wants to, then feel free. It would be a good learning experience.

As I said, download and read the LM4780 datasheet!
