Is it possible to set the frequency response of STA350BW to up to 40kHz by having a higher cut-off frequency LC filter? The I2S input frequency is set to 192kHz.

    Hello JSun.5, warmly welcome to join our community for the frequency response extending to 40KHz discussion. allow me reply your question: the answer is yes, our STA350BW can ​set up to 40KHz by LPF of LC main network, the curves here I attached the some simulation of different Rloads such as 4ohm and 8ohm conditions.0693W00000aIdElQAK.pngkindly let's know if there is anything unclear about ST Audio products.

    Thank you for your great cooperation!

    Best Regards,
