It is called unity gain structure, not unity mixing. Know the difference. I don't know of a manufacturer that suggests that a show is mixed using the preamp gain knob. Unit gain structure does however allow each microphone to receive the correct amount of gain for that particular mic in that particular system venue setup. After the correct gain for each mic has been set via unity gain, the so-called, engineer is free to slide the faders to their hearts content and mix as how they desire. Occasionally a (again, so-called engineer) might have to go back to the top at the input gain and make an adjustment that reflects changing environment on stage but this is not called unity mixing. I'm older than dirt and back in the day there was no variable gain knob. Gain was preset and it was a problem for low output mics such as an SM57. Next came a 3 position gain switch that gave 3 levels of gain and finally a variable gain pot. Being able to use just the right amount of gain and avoid the noise floor is critical. Not setting the master fader to unity and the channel fader to unity and then setting the correct amount of gain will introduce excessive gain (noise) into the signal. EG. if the ch fader is set to 50% and the master is set to 50% then the input gain needs to be set much higher (noise) than needed and also input distortion will occur. Again, it's called "Unity Gain Structure" not unity mixing. Know the difference. BTW, we used to have to make our own mixing consoles as you could not just buy one off the shelf. The Monterey Pop Festival was mixed on a mixer made just for the concert. The host of this video might be better serving teaching how to get the musicians (with amps) to not turn their amp up when the so-called sound engineer turns the level down for that musician.

Good explanation😍😍 Thank you sir

Thank u very much. Valuable info

I started my journey at church in high school over 20 years ago. Never in my life have I ever known that unity mixing was a thing. Without proper training, i very quickly realized that gain adjustments was/is very finite. I always run faders, except to make louder adjustments as needed for initial setup

for studio mixing

What a great Allen & Heaat, I was one time buying one, but sellerman have Spirit Live 3 with great pricepoint for me, so I got Spirit.

revealed a fault, but didn't define solution or experience of it done correctly; not sure how helpful this is to those who have been trained to use unity as a starting point for a channels mix.

It's 2022 and I just came across this great video. Thanks, SLA...

Thanks Sir. Do a video on amplifiers also. The attenuator and matching with speakers

Hey! This is a question I posted from your Center-Fill video from 11/20/2020. Thanks: "Good Morning! Question: So when you say, in your example, "30 feet for each side..." does that mean 15 feet to the left of the [left side speaker] and 15 feet to the right of the speaker?? Meaning, in your example the left and right FOH speakers would combine to provide 30 feet of coverage in between the two speakers?? So, if you had them 40 feet apart, with the 90 degree horn, you would be missing 10 feet of coverage in the center of stage, and possibly need a fill speaker?? Thanks, as always. Carl"

nicely put, sir! use those faders!!

First off this suggests that people are quite commonly simply adjusting gain for their mix. And while doing so does adjust everything after, I think your explanation missed a key point. That being, how to use it correctly.

Regardless of all the sound quality and S/N ratio things, gain knob is at the very start of the signal chain, influencing the strength of this channel's signal not only on main buses but also on auxes, groups and direct outs. Fiddling with gain knobs would certainly mess up the monitor mixes and OB mixes coming from aux buses. For digital systems in which the same stagebox is shared by multiple consoles, messing with the analog gain will even mess up mixes from other consoles.

There are many times when I see mixing consoles configured this way - which I don't agree with at all, for the reasons mentioned in the video. I don't even see any use in this configuration and I consider it a potential error, in case things go wrong. Anyone who uses this type of configuration may regret using it. And when you regret it, it may be too late in the course of a show.

I didn't even realise people would mix with the gain knob. Does the gain knob control the input volume of the device connected to it? Does the fader control the master level of all of the FX? Thanks

what is the correct way to use gain and volume fader for a live band? im using rockford mixer

True

May i know the name of this consoles?

The only problem with the setup up you are talking about is the constant changing of the GAIN. Which is not good at all
