| Jan 6, 2022 at 16:45 | comment | added | icodeplenty | @VladimirNani my best guess is that these are the ground references to each LEFT and RIGHT channel, and could be managed differently in other products, or just an artifact of the main audio amp board that separates them. I think its actually pins 2 and 5 that are in question. Note the silkscreen marking in the photo (just above finger) that provides the number reference. | |
| Jan 6, 2022 at 10:14 | comment | added | Vladimir Nani | @icodeplenty thanks for the answer, i was wondering specifically about J5, why have pin number 7 at all if it is being shorted with pin number 4 | |
| Jan 4, 2022 at 22:04 | comment | added | icodeplenty | Oh @Transistor, but I agree with your other comment about the L1, L2, etc. parts being inductors for noise when installed, but jumpers when not. | |
| Jan 4, 2022 at 22:01 | comment | added | Transistor | You are correct. I'll delete my comment. Thanks! | |
