Hi, some one know, can i use one attiny85 to programmable two MA12070 at once? Can i merge SCK, SCL?
I need it for dual mono MA12070

According to the datasheet, AD0 (pin 28) and AD1 (pin 29) dictate the amp's I2C address. Looks like you can have up to 4 amps.

Friends! help connect the amplifier module on MA12070p (1.6v black board from Aliexpress, digital i2s input) with DSP adau1701
When connecting MCLK (amplifier-dsp) it gives an error when loading the firmware into the eprom. Following the advice, I connected MCLK to BCLK DSP. I set the settings (I hope that they are correct) in SigmaStudio as a result the sound from high volume speakers is distorted and it is not regulated by the volume level from adau1701 (from SigmaStudio). I assume that the volume level can be adjusted through the ma12070p registers using mh-tiny and arduino IDE, but I have not found information on how to do this anywhere.
What am I doing wrong? how to achieve results?

I'm using SigmaStudio 4.7 and I don't know how to enable Left Justified (I saw somewhere that this is enabled by the :MSB Position delay by 0" option, but I'm not sure)

Your settings are correct, but I'm not sure if this is ok:
I use MA12070P with ADAU1446, and it needs 4 signals: Data, MCLK, BCLK and LRCK
When I connect mclk to adau, sigmastudio shows the "comm filed" error (even when the amplifier's power is turned off).
when I don't connect mclk and turn on the power to the amplifier - loud clicks
when I connect mclk to bclk - as I said earlier, the sound is very loud and distorted, and the volume control in sigmastudio does not affect anything
my ADAU config attached
I found "left justified" in the "serial input" block, but it seems to me that this is not what I need, since I use the DSP analog inputs and digital outputs, because my amplifier is digital

If you have an oscilloscope, connect the probe to MCLK signal and check what is happening while you connect the ADAU.
Is the 1.6v a typo? I've only seen 1.4 and 1.5 versions of the board. Have you connected the 1701's BCLK to both the MA12070P's BCLK and MCLK? It looks like you have the 1701's serial output set correctly: the "delay by 0" is "Left Justified" mode. If you change it to "delay by 1" it's called I2S mode. Hope this helps.
Thank you!
Perhaps I misunderstood and connected the mclk of the amplifier to the bclk of the amplifier and the dsp (by simply shorting the bclk and mclk contacts on the amplifier).
but it was necessary to connect the mclk from the dsp to the bclk of the amplifier and the bclk dsp?
And this message confuses me: https://www.diyaudio.com/community/threads/infineon-ma12070-class-d.347422/post-6532022
I received the tsa6179A AudioB Bluetooth 5.0 Audio Receiver Board support Apt-X that I ordered for the ma12070. In TWS mode, each Board stereo channels worked separately in mono. My goal is to make an active speaker. There will be ma12070 + tsa6179a in each column. They will connect to each other wirelessly via TWS. I'm getting closer to the result.

Does TSA6179 have DSP so you can do the crossover for a two way active? Whats the programming environment for that?
You might want to check out the NVArcher DSP BT boards in this thread with two outputs.

They provide software and boards are $15. Several people have successfully used it to do this.
I got the boards myself but have not had time to play with it yet.
