PCM5121: PCM5121

Hello，

 How to  configure the 1.1 channel output？ During debug，EQ1  and EQ 2 are sync, how to configure them independently, for example EQ1 is used for low-pass filter and EQ2 is used for high-pass filter?

Do we have some related documents about 1.1 channel configuration? 

Best regards

    Hello Kailyn,

    You can configure the biquades independently ( for example one as  low pass, and one as highpass and etc. ) Just Right-click on the the Biquad of interest and select  Biquad GUI, a new pop up window opens up  that you can configure the biquad with your values.

    Hi Arash，

    Thank you very much for your reply.

    But when configured  independently,  for example, when configured biquad1, the biquad2 is  also changed with biquad1, now we have no idea to configure them differently, one biquad is always changed with another configuration. Please refer to the below video.

    Best regards

    Hi Kailyn,

    If you build the flow yourself and drag the components you want into your flow, then you can change the biquads independently. However if you use the Rom  Flow ( which is what you are showing above) then it is not possible to change them independently. So you can do 1.1 channel if you build the flow yourself.
