TAS5825P: How to switch between two different DRC setting?

Part Number: TAS5825P

Dear Support Team,

Very Thanks for your great support!

If we want to switch between two different DRC setting (the difference between the two PPC3 is only the DRC!)

How can we switch them dynamically?

Note 1: Our product setup TAS5825P through MCU.

Note 2: We have tried to re-send the full setting, it is work! But it takes a long time (3.5sec) to complete.

Is there a faster way to complete the switch? (We also tried to re-send only the difference, but that doesn't work!)

Thanks!

  • Hello Mick,

    When you say re-send the full setting do you mean all the Process flow registers or just all the DRC registers.

  • Dear Luis,

    Very Thanks for your great support!

    We have try to re-send all the Process flow registers, it is work! (PPC3's .h file Total 6044 bytes, need 3.5 second to finish.)

    So, if we can re-send just all the DRC registers, maybe can more quick to switch deferent DRC setting.

    But, we have no idea about which area is start, and witch area is end for all the DRC registers.

    Thanks!

  • Hello Mick,

    An easy way to see which DRC registers to modify is in the Purepath console enabling the i2c monitor recording and enabling the DRC processing block, the I2C monitor will dump the script of the associated registers with that processing block that you could copy over and write in the i2c prompt.

    best regards,
