set the volume to 0db. then calibrate with -20 pink. 0db = unity.

from there you can change it to spl mode and specify the spl you set 0db to, ie 79, 82 etc

Thanks for your reply Ken...
"set the volume to 0db" means on the OMNI itself?
Signal Generator to -20dbfs Pink Noise RMS or Peak?

Hey Ken, I see you're also using the JBL LSR 4328 5.1.
When you calibrated the levels on each speaker, did you use RMC first or after?

And while you were calibrating, did you have the sub gain at +10db (which is separate from all the speakers +4/-10)?

Thanks!

Levels are adjustable within the front panel.

Stereo is a subset of 5.1 in the IO

I use 5.1 for mains, the stereo subset for stereo mains, ALT for Avantones through 7&8.

Yes I calibrate after RMC and b-chain equalization. Sub is +10 engaged. I don't have a RTA so I followed Dolby's guideline to calibrate the sub 4-6dbc above the center channel.
