New Wondom ADAU1701 DSP Unit

[Nisse10000]

Internal photo. The DSP is a BP1064A2 and part of the datasheet can be found here. The DAC is an ES9023P with an AD22650 line driver to generate the 3V the subwoofer output and an LM4558 on the line level input. The Bluetooth module is a QCC3040.

The BP1064A2 has only one SPDIF interface that is switchable between RX and TX, so I presume the undocumented MS8406 with what appears to be a factory bodge is a codec to add a second SPDIF interface.

This looks like a really nice device given its price. It would be almost perfect for a simple TV setup. The only thing I would be missing is a second sub. Is it possible to EQ left and right independently in ACPworkbench.

(Thanks for the advice on the NVarcher, for the price it is a bargain)

I have been playing with both the Go Control mobile application and ACPWorkbench. We do indeed have ten per-channel PEQ filters, as you can see below.

This is in addition to a master PEQ bank for both channels.

The Go Control application interacts with the DSP registers quite interestingly. The application displays only eight fixed-Q graphic EQ bands but there is more functionality present than is immediately apparent. If one configures a full bank of ten master PEQ filters via ACPWorkbench and then saves a preset within Go Control, that saved preset will correctly represent all ten of those filters with their proper frequency, gain and Q parameters.

The coarse tone control sliders on the Sound page do not visibly alter any parameters within ACPWorkbench, so I presume those are writing different registers that aren't exposed there.

I'd also like a direct path possibility (analog-analog) and the preamp to work in that domain. A coaxial in would also be great to connect my cd transport. (most of these have only this digital out option)

Does it work with any version of acpworbench? Like ones not supplied by arylic themselves? (nvarcher ones )

Only Arylic's version will detect it.

Edit: The Nvarcher version does in fact work.

This is great news! What's your general opinion on it? Have you tried all of its features?

It's be really nice if anyone could build a complete product around this board. With an enclosure and all the possible ins/ outs available.

Anyone know where I can find the datasheet for the regulators referenced in post #42 on the Wondom unit marked "S55ND" (U203, U205, U206). I searched for an hour, with no joy. 3.3v LDO? More out of curiosity, and for continuing my self-edifiction/education irt circuit design, etc. Some of you guys are absolute wizards! TIA

Also, thanks to anyone and everyone here for contributing to my self-education via your generous contributions via ASR. You folks are beyond rad!

Could be SG Micro SGM2028 3.3V version:

ND=April 2023. Fresh stuff!

Thank you brotha! I wasn't expecting such a quick response, thanks for taking the time, it was really kind of you It's acts like this, that make ASR what it is. I've learned more about practical electronics on this forum than I have in any formal setting. I've learned that keeping my mouth shut (unless I have something of value to contribute), and my eyes (and brain) open in the presence of absolute legends (like yourself, Amir, Weeb Labs, etc) has been an absolute gift. Been on here for quite a while and rarely post (too busy learning , but when I do, I'd like to convey my gratitude and admiration for the depth of knowledge that's so generously provided. Thanks again everyone

Edit: P.S I must say, even given economies of scale, and that ADAU1701 is now a mature product, I was quite surprised at the quality of the Wondom unit. The way they silk screened the pcb and laid out/labled the headers saved me the time of tracing it all out myself. I've rarely seen this sort of effort before. Especially for the modest sum of $30/shipped to Hawaii!!

Stay safe and take care everybody

It is effectively a cheaper, vastly more functional MiniDSP 2x4 (which also makes use of the ADAU1701).

Would you be so kind to expand on this using simple terms to someone that has never had DSP and is trying to understand speaker measurements for the first time and how to go about it with minimal budget please? Or would this be too advanced for a noob and should I stick to the MiniDSP? Many thanks in advance

I would guess too advanced, but may depend on the skills and aptitudes of the noob in question. MiniDSP have configuration software aimed at end users. For the Wondom you need to use SigmaStudio which is aimed at developers and is more like a graphical programming environment.

guys fyi, wondom has youtube videos for programming of this dsp, im a newbie in this so im gonna follow the video and buy an icp5, it's not very expensive.

Hello, this is the first post I decide to write.

I've been reading about this wondom for a while now and I have doubts about whether it can do what I'm looking for.

I intend to use it as a filter and parametric EQ for the same subwoofer by two different outputs.

I use the same subwoofer for my Hi-Fi and Home Cinema sistems and both settings require different settings in terms of frequency cuts and gains and I intend to use the wondom for this, for example using the left input for Home Cinema and the right for Hifi, apply the different filters, gain control and EQs separately and route them to the left bankA and right bankA outputs.

I'm starting to use Sigma Studio and using the demo program that they provide, I think it's not extremely difficult to do it, but I don't know if I'm missing something and that's why it's not difficult for me.

another option is to buy the T.racks mini 4*4, this can also do what I am looking for but at more than double the price and I don't know if the overall quality and the board itself are so much better or they are just very similar and you pay for the advantage of a plug and play software.

Thanks and sorry for my Google Translate English.

Yes, you can do this. Here is an example of how you might go about implementing it.

I just got the wondom unit (with the enclosure and knobs) and was wondering how to get a higher level out of it? It seems very quiet compared to my output from my interface (umc204hd, which was already low signal 1v RCA)
