When I insert the plug-in and load my Measurement, I have a strong level decrease on my monitors.

This is normal.

The ARC 4 processor, in order to fix your room acoustics, need to apply cuts to the spectrum areas where the room is boosting the sound.

In the same way it needs to add a boost where the room is attenuating the sound.

For this reason, the ARC 4 processor needs to get headroom enough to fit the maximum possible boost it can apply, which is 12 dB.

Not all rooms will need 12 dB of boost, but that’s the worst-case scenario.

The TRIM knob is where this attenuation takes place, if this knob is pushed into the “red” area there is a possibility to clip and overload the DAW outputs.
