Hi Zheng,
I have a separate question
"Seperate questions" are to be put in separate topics, so I just did that. haha.
I am afraid that this is your DAC. It may be hard to explain but for me this can "locically happen". However, if you recognize this is happening to all your DACs (I assume you have a dozen
) then we may try to investigate which setting causes this. Anyway I would try the (Q1) 30x40 (assumed you set that because "we" do lately) back at a normal 14x1. I think this relates to what a DAC can fail upon.
Btw, maybe there is a misunderstanding about what is "soft fade in" as such. I think you refer to something like what software is doing to you, while I'd say the level gradually increases (which is quite explicitly not what you mean, I think).
Let me know what happens.
Best regards,
Peter
