ADAM Active Studio Monitor schematic diagrams help

So so so. I solved the problem. The problem was not in the board where the capacitor burned out. There is 1 more scheme. All electrolytic condensers on it had no capacitance. If your speaker is playing quietly, replace all the condensers -> 25v 220mF 1 piece, 25v 100mF 4 pieces, 25v 22mF 5 pieces, 35v 47mF 1 piece.
Then I changed them on the work speaker, because after checking they had 50% capacitance

Good luck all. Thanks 😉

Hi.

I own some ADAM S3X-H studio speakers and one of them won't turn on.
I am looking for the technical service manual to be able to repair it (it is not the fuse).

Could you please send me that manual?

Thank you very much in advance.

Hello. I really need a circuit diagram (service manual) for Adam A5X monitors. On one of my monitors, the tweeter became significantly quieter over time. The tweeter itself is in working condition, the problem is either in the amplifier or in the power supply. Without a diagram, it is difficult to understand and repair. I will be very grateful if you help. My email is [PI removed on request]

Gentlemen,

in my workshop I have these active S1A "Professional Studio Monitor"
loudspeakers for repair. The amplifier is defective. Resolved, this is an
ADAM schematic collection now.

A diagram of this module would be useful. It is made by Hypex of the
Netherlands, no designation on it but date 10 Jul 2003. It carries a vast
number of NE5332 ops and two TDA7294 power amps, one LM339 and
one TL074 are also visible. Should be manageable to repair, but all traces
and joints are very small - doesn't help my eyes.

The Adam company which is in Berlin says that they don't have any
documentation and can not repair it. Since many of these were sold
it would be good to have them fixed in the true sense of sustainability.
I suspect that other people have problems with the amps also.

I understand that the head of R&D of Hypex is also around in this forum.
Will he be willing to assist?

Any help is highly appreciated, thanks.

EDIT: Diagram for S1A is in post 10.
Diagram for ADAM P33 (UCD-Version) is too large, I can send it by email.
Schematic for ADAM P7 is in post 12,
Service manual for ADAM P 11 A UCD see post 16,
P22a schematic via email

Model S1A (and others) transformer mounting precaution in post 19.

ADAM S3XH Service Manual can be received by email, send a pm.

Can you please send me the schematics to the s3xh ( :cop: Mod Edit email removed as requested)

Does anyone know what parts these are on the s3xh motherboard amp section. They need a replacement and they are coded. No way for me to figure out what they are so I can replace with an equivalent

Instead of sending blurry pics just read what is written on the parts.
Describe the type of error first, no speculation please.
If your serviceman is not able to identify the parts he should absolutely not try to "repair" this.

I do not have the speaker right now the repairman does. As for the error. The speaker had just stopped indicating it was on. The led on front was off and no sound was being emitting through the speakers. Tested the lower supply and got 120v so the power is fine. Repair man said he was reading a short along the circled parts in the picture. Once I get the speakers back I will read the part numbers off to you

The error must be in the supply I guess and not in the amp.
How have you "Tested the lower supply and got 120v" ?

"Googling" your type numbers the first one immediately leads to many results, the second one may be in error.
If your serviceman is not able to identify the error location and parts he should absolutely not try to "repair" this.
