Fidue A81 EQ settings

For the A81: one published correction, made by AutoEq. FluidEQ applies a correction to everything Windows plays, offline, as a layer that never touches your own bands.

What the corrections do

Each line is what a correction does to the sound from 20 Hz to 20 kHz: above the middle line it turns that range up, below it turns it down. Pick a tab to see any correction on its own.
