When possible, round values as much as possible. I mean, nobody is even able to hear a 0.1 dB of a difference let alone 0.01 dB !! E.g. the current gain setting is in XX.XX dB.
It would be much better to set the preamp gain in just whole dB digits, perhaps with a 0.5 dB accuracy. This way setting 2 channels at the same value would also be much more simple and visibility would improve as well.
Edit: I slightly adapted the title here, to be more specific about the scope of the topic. I noticed that this is also the case in some CS18AI settings, where operation and overview is also suffering from these unnecessary decimals. E.g. the EQ gain settings. Besides, this way there is an impression for users that these 1/100 dB differences matter when setting values, when in fact there is no practical use.
