Parametric EQ unable to set negative gain for any bands.

[HeadHunter98]

Hey guys! 

I just got myself an LG G8 along with owning an AKG K545 and I am interested in squeezing the best sound possible. I started digging through UAPP and found about Parametric EQ and AutoEQ's presets. As I started to set the parameters, I realized I just could not set a negative gain on any of the bands. Any ideas how to overcome this issue?

Still works fine here. You are using the second column?

Oh, so it's the second column, not the third one? Some clarification within the app would have been appreciated (or I didn't look deep enough, however it would be the best in 10-band mode as well). Thank you, regardless! 

Furthermore, do you have any sources for proper AKG K545 parametric EQ values? On AutoEQ's github I could find no corresponding set for this nor AKG K551 which is supposedly based upon. I tried AKG K550 and MKII as well, however it rather mufflers the frequencies than tuning them properly. I would appreciate it!

No, we don't have any figures on any headphones, sorry.
