hello,
There is no problem and nothing to fix…
let me explain…
A max level in digital domain is 0dB
When you set a positive value in the EQ (ex 3dB) for a frequency, it means increase the signal here. As it is not possible to go above 0dB, to get the same relative effect, everything is set 3dB lower exept the frequency you choose. If you don’t do that, signal will be clipped! With a very bad sound. FusionDsp auto adjust this level by default according to EQ settings. You can disable this in ‘more settings’ and ‘auto preamp’ off. But signal may be clipped. All software require a attenuation (pre-amp) to work properly.
This not a FusionDsp issue, but an easy way to enjoy music without bothering with complex settings.
Enjoy
