Why do autoeq profiles come with negative preamp volume? (alien.top)

I’m new to using EQ. I find I have to increase the volume going from no EQ to loading an EQ profile. Do I increase the preamp back to 0db, or leave it and increase the main volume?

When you raise a frequency above flat, you're basically turning up the volume of that frequency. When doing so, you have to turn the preamp down by a roughly equal amount to compensate so you don't cause distortion.

Short story. Leave it and increase the volume.

Thank you! I will try this out on APO and see the diference, mainly when i got my hands on DT880 Pro (or the K52 since i want is as an step headphone since i selled my hd569, it was uncomfortable, i could feel the earcup edges against the own earpads and the foam was minimal)
