7-channel DSP with Mvsilicon BP1048P4

Hi everyone,


I recently replaced my Nvarcher 3-channel DSP board in my car with a 7-channel DSP board from Aliexpress (link here), hoping to get individual control over all my speakers — especially to separate the front and rear channels (they currently share the same line out).
This board seems perfect for my needs:
  • Based on MVSilicon BP1048P4 (same family as my old Nvarcher board).
  • Has TOSLINK input, which would eliminate noise from redundant DAC-ADC stages.
However, I'm hitting a wall:
  1. Despite the matching MVSilicon chipset, my ACPWorkbench (that came with the Nvarcher board) does not connect — the board shows up, but stays "disconnected."
  2. I didn’t receive any Windows or Android software with it.
  3. The AliExpress listing refers to a "GoloPine" DSP tuning app, which I can’t find anywhere online.
  4. The only place I’ve seen this GoloPine software working is in a Douyin (Chinese TikTok) video from this user: Douyin link. You can even see the APK filename as golopine_audio_turning_release.apk.
I’d love to know:
  • Has anyone else bought this board or received the GoloPine software?
  • Is there any known method to back up or extract the firmware/software if someone already has it?
  • Are there any pinout diagrams or documentation available for the board especially the ribbon connectors?
Thanks in advance — I know support for these no-name boards is always a bit of a lottery, but any tip or shared software would be greatly appreciated!

Cheers,
Gergely

Hi

This DSP was used in the Arylic board I am using and - my ACP work bench was not connecting - in several boards, all of these boards were either damaged by me by mistake - or they were from other companies other than Arylic

It seems Nvarcher too use the ACP workbench

There has been one other case - where the ACP work bench did not communicate -

That is - the 2nd page of ACP workbench - is set up as per the frontend sold to us i.e. mine was a 2 way eq for Arylic mini. The board will show connected - but not communicate if your ACP workbench does not have the 7 channel front end as shown in the Aliexpress link - most likely - I am not sure - but this was the case.

I am happy with Arylic and had ordered a few more - same pcb - different usage & different firmware that had a different frontend to my ACP workbench - and this resulted with it not communicating - once the firmware was updated - this was by OTA - the pcbs started communicating, Arylic has their own process for firmware upgrade - support was good.

I am surprised this dsp is capable of 7 channel EQ with 15 bands each - but i guess it maybe possible - if one removes the unnecessary effects features that are in the firmware.

I gave this to Deepseek and it gave me some actions , maybe these can be followed up - (I think targeting to locate DSTech_DSP_Amplifier program maybe a way forward)

Go to Baidu and help to find DSTech_DSP_Amplifier android app & windows app using MVSilicon BP1048P4 DSP to connect with the following module :- https://www.aliexpress.com/item/100...678a7884245922e32466fa8dc56&afSmartRedirect=y

All the best

With that said the DAC of this DSP needs an serious upgrade - I used the ES9023, are there any DAC in your PCB,

This PCB looks like a good solution for the price - once programmed everything is pretty stable.

There is another thread w.r.t. this DSP, and there is some more information pin out and configs.
