It should adjust where the brake lever sits. As in how far away from the bars. You adjust it for your riding comfort. Try turning one way and you should see the lever move in or out, the opposite way does the opposite. It does not change how your braking works, just where the lever itself “rests”. People with large hands often want it out further, small hands in closer, but it is very much a personal preference.

It’s a reach adjuster… It moves the lever closer to or further from the handlebar to accommodate different hand sizes so you don’t strain having to stretch your hand
Edit – I’m mistaken 🙏

It adjusts the leverage. The closest position to the pivot point gives you MAXIMUM STRENGTH (Crysis pun) but stortest cable travel.
I saw those levers in person but never used, would be interesting to try.

Turning the red knob changes where the cable attaches relative to the pivot, allowing you to adjust the cable pull ratio. Moving it closer to the pivot results in shorter cable pull, but more leverage. Combining this adjustment with compressionless housing can really help you dial lever feel.

Leverage adjustment for how much brake cable gets pulled. More cable pull more brake.
8 Kid answer: when you can not reach the brake to squeeze it, you can turn this screw and make it easier to brake.

Like other comments, it lets you adjust the leverage you have when you pull on your levers. Think about turning your wrench with your hand at farthest from the nut (more leverage) vs. closer to the nut (less leverage). You pay for it by the distance you have to move the lever to get the same amount of force on the other side. More leverage comes at the cost of more distance.
One key note that others haven’t mentioned is that there is another set of levers that act at the other end of the brake cable: your brake itself. Adjusting your levers isn’t just to change the “feel” of your brakes. Your brakes themselves are designed for either “long-pull” or “short-pull” leverage for optimal usage. Cantilever brakes are designed for short pull strokes, and expects a shorter cable pull (move the cable anchor as far away from your bars as possible). V-brakes are designed for long pull strokes at the opposite end.

It alters the lever pull ratio. Fine tune your brake “feel”.

Edit: oops wrong knob
Adjusts brake lever position.

It’s in the manual. https://nuxx.net/files/bicycle/avid/speed-dial-7-install.pdf
Changes the “feel” of the lever. You can make it softer (more modulation) or firmer.
It has to be set in the middle when installing the cables.

8: the lever is adjustable, this knob adjusts how far you can squeeze the brake lever.
5: squeeze brake go stop. Turn knob, squeeze less
