Just a noob from Germany ready to learn because of recent problems with my speakers.
My Adam A77X stopped working recently.
Both speakers are having the same issue.
They create a popping noise like a metronome. Audio ist still Pasing through them though.
I have a friend who could repair them but he told me he is helpless without schematics.
Could anyone provide schematics for this speaker? Would be highly appreciated
.
Thank you

Welcome and let's see...https://www.mixingtable.com/adam-a77x-inside2
The power supply is a switching type, probably the glitches are coming from it?!
If you have some linear supplies around ( transformer, diode bridge and capacitor), maybe your friend, and providing the auxiliary voltage(s) for the line section, that is a first check.
I guess.

Capacitors are looking fine so far, we already changed one that was funky looking.

That would be very slow motorboating. I've never seen that, but it looks like DC bursts that alternate between positive and negative.
I believe these are Hypex modules. Can you confirm that? I think moving this thread to ClassD might get more responses.
Thanks for answering this thread.
I can not confirm if these are hypex modules atm. Speakers are at my friend's place right now.
And thanks for the tip to put it in the class d forum.
I already posted as a reply in an ongoing Adam thread. Waiting for mod approval
