Hi, Zhuo,

I have asked my colleague to address your concerns. He is currently out of the office, so it may be a week until we can get back to you.

TAS5713 has a lot of differences between TAS5707 and TAS5708,so may be i will stil need your hands anymore.

Hi Zhuo Yue,

sorry to ressponse late.

and for the pre-scale and post scale, is two gains to regulate the THD+N at different power

you could use the pre-scale to make distortion, and use post scale to adjust power.please kind find the attachment about this.

if any questions, please kindly let me know.Thanks!
