James you're the best contributor for SSL video learning out there! Thanks so much for your gift to the community. Always learning from you!

Keep up climbing that ladder, I am proud of you my friend!

Said that, I have a few questions regarding your procedure:
- could you elaborate on the dbFS values you're trying to hit individually on PAZ Meters for 2-bus, A, B and C?
- From what I depicted from your video, you're setting the 2-bus to hit -10dBFS on PAZ Meters, but when you're calibrating A,B and C you're reaching other values (for instance on B you dialed around -9.5dbFS). Is there a criterea?
- When you're mixing and A,B,C are summed, what are the peaks readings you're getting in Protools?
- During the entire process how is your main fader set up?
- Finally, you're calibrating outputs from your outboard compressors to get the levels you want on the way out, but how do you set/reach to the level of compression you want to get on the way in to each bus?
Thanks mate!

PS: we really need to make a DIY multi-input trim box! Using that neve just for trimming hurts my eyes and heart!

Cheers,
Artur
