Hi everyone! I am hoping to get some clarity here on what level was used to calibrate the Orion 32+ Gen 3's Monitor Outputs - in particular whether a -20 dBFS or -18 dBFS 1kHz sine wave was used to to calibrate the outputs to +4dBu?

If you are wondering why I want to know, it is because I would like to calibrate my analog monitoring chain and my speakers. Being the Orion is first in the chain I want to know what the outputs are calibrated to.

I wrote Antelope Tech support and they could not answer this question...which is kinda crazy considering the Orion is an expensive piece of hardware used in a professional setting. That said, if any of you kind folks can confirm whether it is -20 or -18 I'd be mighty grateful. Thanks!
