Part Number: TAS5508C

Hello experts,

My customer plan to use TAS5508C, and they need to set EQ which they want to implement.
TAS5508EVM's GUI has some sample, but it can't set EQ which they want. 
By using ALE(Automatic Loudspeaker Equalization), they plan to set EQ.
Do you have good application note or reference for using ALE?
Thanks and best regards,

  • Hi Ryo,

    Sorry but we don't have related materials. Would you like to take a look at the TAS5548EVM-GUI? It can also be used to configure the EQ function. Hopefully it helps.

    Thanks!

    Hello Hao,

    Thank you for your quick reply.
    You mean TAS5548EVM-GUI can be used for TAS5508C EQ setting?
    I'm sorry, I'm not sure the detail. Could you tell me detail more, please?
    Thanks and best regards,

    Hi Ryo,

    I mean you may run the TAS5548EVM-GUI offline, set your EQ curve in the visual window, get the register values by "save settings", and then open the saved files.

    GUI->Loudness1->Launch Loudness Filter-> Choose "Equalizer(Bandwidth)" in "Filter Type"->Input your parameters and check the curve in the window below->"Save settings"-> Read the settings in "Paramter" lines.

    I'm not sure if it can help here. Please take a try. Thanks!

    Hello Hao,

    Thank you for your reply.
    Let me ask more detail.
    I installed PPC3. But, unfortunately, I can't find the function like TAS5548EVM-GUI.
    Also, there is no description about PPC support TAS55xx device in PPC install page (I have already requested PPC SW.)
    Which software can we use for setting EQ of TAS5508C?
    Thanks and best regards,
    Ryo Akashi
  • In reply to Ryo Akashi:

    Please try with PPC, not PPC3.

    Thanks!

    Hello Hao,

    Thank you for your reply.
    Let me confirm the detail.
    I can set EQ and save data as you advised.
    You mean the saved data (like picture) can be load in TAS5508EVM?(I'm sorry, I can't install TAS5508EVM-GUI on my PC, so I can't confirm.)
    If I can understand your advise correctly, I will tell customer.
    Thank you for your support.
    Thanks and best regards,

    Hi Ryo,

    No. I mean you can leverage this GUI to get the EQ parameter design. As you have seen in the <parameter> lines, these results can be manually wrote into TAS5508C registers. 

    Thanks!
