On a digital console?

That guy is a cretin.

Cheers,

Unfortunately 95% of sound-guys are cretins... Harsh reality learned from a lifetime of gigging (and sound-guying!).

Transformer saturation, is often not as great as people like to think it is, transformerless is completely different.  Bearing in mind almost all pre’s these days are the transformerless design, just saying...

So he cranks it up,to compress it down...... wait.......what?
To each his own I guess, that sounds like you be smacking😘 the preamp so hard you would have a near or at distortion issue

Exactly. I believe he is trying to apply his studio techniques to live sound.

With the mic gains so hot, he runs the channel faders lower and the master below unity.

Whats the drawback to running the master below unity?

On a couple of consoles, your master meter is post master fader.
Depending on your gain structure, there is a potential for overloading the L/R bus before it shows up on your master meter.
I always run off a matrix to avoid it on any console. Leave the master fader at unity and adjust overall levels with matrix master(s).

I'm getting confused. I've read here on the board that even if you hit the pre low, it will still sound good on a digital desk. Since it's digital. But here this guy is saying that if you don't use all the bits, it will sound bad.. I started my career in the analog domain and didn't think much of the digital domain, and still need to understand some basics other than "don't clip a digital circuit, it sounds worse".

"Fill all the bits" is a misunderstanding that comes from early digital users.

Dither completely resolves the 'fill all the bits' concept. Because of dither, all bits in digital are equal—there are no better bits or bits that need filling for good sound. Don't fill all the bits, you're supposed to have headroom!

From a noise viewpoint, low pres are fine, but as the video explained, the resolution increases with higher input gain up until clipping, where it will always sound horrible.
Without the A/D converters (analog), the resolution doesn't change, avoiding the noise floor is encouraged, and clipping the pre may not sound so bad.

That's my impression. So basically what this guy in the vid is saying is "wrong"? Not directly wrong, but the importance of it is close to non existent?

"This guy" in the vid was Tom Petty's FOH, has mixed Rush and Matchbox20, among many.

The take away I got from the presentation was "set preamp gains for best control resolution."
