Hi, Derek

I have download PurePath console 3,

and I would use PurePath console 3 to control the TAS6424-Q1 EVM.

Where can I set the time delay between every speakers to create directivity effect?

Maybe is this part in following picture, or something else?

Thanks.

Hi Joan,

You need play a 19KHz, 0dB sine wave audio source to device, using external signal generator.

Before you do AC diag, I suggest you can do DC diag firstly to check if any DC load error.

Hi, Derek

Thank you for your answer.

Another question is what number I can set for each channel and then will create directional effect?

Hi Joan,

I can not understand you completely.

Do you mean the 19KHz, 0dB sine wave audio source for AC diag?

That's digital input for 4 channels, TDM or I2S interface are both fine.

Derek

Hi, Derek

Thank you for your answer.

Well... I want the 4 channels have time delay effect between each other.

Like the following picture

And how can I set the data for each channel?

Hi Joan,

The 4 channels have identical time delay.

And we have no open registers to adjust it.

I am sorry for inconvenience.

Derek

Hi, Derek

Thanks your answer.

And there's another question:

In the following picture, what's the Phase's function?

And can I set up the phase data separately?

Best regards,

Joan

Hi Joan,

I think attached pictures of speaker model and AC diag can explain your questions.

The phase data can be read separately by registers.
