* USB hardware volume means that the volume adjustment function of the host can be controlled through the volume buttons on the device to synchronize the volume between the device and the host. Or you can directly adjust the volume of the device through the volume button on the mobile phone instead of adjusting the amplitude of the digital signal.

FAQ Notes
Is it a problem to connect to FC6 on the mobile phone, and is it a big noise in NOS mode?
- FC6 is limited by volume, and the Darwin R2R architecture used is relatively poor in dynamics;
- The performance of poor dynamics is that it performs poorly on small signals;
- When the volume of the mobile phone is lowered, the input is all small signals. Due to the dynamic difference, the small signal processing is poor and the noise floor is amplified;
- Users are advised to: turn the volume on the mobile phone and then adjust it through the FC6 volume control; (There is also this problem for RS2 and RS6)
- FC6's HDR means high dynamics, which is used to solve this problem;
