Germany(and France maybe?) has a special legal package application that need apply per-year,so far we hasn't do that yet but plan in 2023.
then you may try again.
thanks!
I’ve ordered two stereo modules. Do they need to be synced if powered by the same PSU and, if so, are there provisions on the board for this?
same as previous one, depend on your setup, for me i won't set it.
think about puifi,hypex module.......
Sorry, not familiar with "previous one". Am I correct in interpreting your reply as:
(A) Yes, there are pins/plugs on the board for interconnecting/syncing the boards if desired...
(B) ... but I don't bother myself (in the right setup, e.g. low-medium power application), similar to how most people don't with the Hypex/Purifi modules
Yes, please - if english is not your native language, just do straight non complicated answers. No jargong etc. Especially if you use translate service because all little nuances get lost in translation.

the previous one is the old one(no feedback) we made before,
if you can read the manual in a short minutes, you may found more info on setup the board.
Well, as you can see from the above posts, people have successfully ordered and are waiting so, yes, it seems like they are, don't they!

Then I think you should remove the options in your store as people might be waiting for them to appear... hindering other sales...

Hello!
*No more socket for Op-Amp change?
*Which Op-Amp comes with?
*What can be change for improvement?
*What does the feedback for sound quality?
Thanks in advance!
PS. I have the old one with OPA1656 + Meanwell 48V + SB Acoustics speakers and love the sound of my 3e amp, thanks for build one of the best TPA3255.
Gustavo.
due to feedback design ,it is not allow to change op-amp as it will degrade the performance.
it use opa1612 for best low noise and distortion, so it is very limited chance to change some components for improvement in diy point of view.
Got 2 amps delivered this morning. I can say that I’m positively surprised- assembly and attention to details is top notch. It’s a smaller amplifier compared to other versions with top heat sink. It’s built like a tank, relatively massive CNC machined aluminum heat sink. Soldered OPA1612 with high quality passives. Post soldering could be a bit cleaner, other than that no complaints. Beautiful piece of tech, shame it will be hidden in a case. Planning to run 2x amps, separate 48V, fed through a ADSP21489 with CS4398 DACs. Hoping to connect all pieces together in a month. Great job 3e!

Got a surprise package at my front door this morning, 2x 3e Audio
Might be a while before I get it running, still waiting for the PSU's from Micro Audio.
@3eaudio Audio, what is J5 and J6 used for?
Got mine this morning, 13 days to US and arrived earlier than expected. Very well packaged considering the weather right now, package was literally waterproof and sat outside in the rain a bit, no water got inside. I can concur, very well built and heavy with the coilcraft inductors and solid machined aluminum heatsink.

It's documented on their site...
To change the master or slave config of the board, in case of multi-board use.

Hi 3e audio,
Currently I have 2 units of non feedback 3255 from 3e audio. Can I add the new tpa3255 with feedback to make a 6 channel amp? Eg use 3255 with feedback for mid, the old ones for high and low frequencies.
The old non feedback amp is out of stock. Are you still making/selling them?
