Yes you interpreted the EQ Curves correctly.

The curves show there is even more gain than you'd expect on specific frquencies. Keep in mind thoses were measured in ANALOG.

What is most accurate about them is the relative differences and not the absolute values. The dB scale may be off (I'm almost sure it's off).

I later confirmed DIGITALLY that EQ3 does indeed need exactly 3dB headroom and Flat does not need any headroom. So +3dB and Flat is safe. And +3dB and EQ3,EQ2,EQ1 is not safe.

I posted these recordings of the center channel but I have not made screen shots of them yet.

Also keep in mind if you calibrated your system "normally" to 0dB if you ran your Center +3dB in Trifield preset you get exactly the same result as Calibrating your system +3dB and setting Preset to 0dB. So even under Meridian's normal constraints you could make things clip.

We just want to be better aware of what things increase gain where when running closer to Full Scale.

This is why I added this feature to my tool. It will summerize risk of clipping and resolution loss on every channel and every preset whether you choose to calibrate to +3dB, 0dB or negative (to reach standard 75db pink noise).

If you think listening to music is fun, try learning an instrument.
