we use 5707 as amplifier when the DRC is turned off, the sound is too small, According to datasheet we can know if we want to set DRC threshold need to fill in several values, how can these values fill in the threshold can increase, Or tell us the DRC debugging method ,thanks!
Hi Darren,
Do you have a TAS5707 EVM in hand? If yes, I think it would be much easier to take up this device. We have very detailed introduction of the DRC usage in this document: 
If the sound from speaker is light when DRC is enabled but normal when DCR is disable, the issue is caused by the DRC setting. You could try to tune the DRC setting according to that document.
If the sound from speaker is still very light even when the DRC is disabled(reg0x46), the issue is not caused by DRC and you need to enlarget the volume setting(reg0x07) or input amplitude.
Best regards,
Shawn Zheng
