Is there a name for a group of value-related sliders?

I need to illustrate a set of sliders. Each slider can be moved up and down by the user.
Adjusting one slider will indirectly adjust the other sliders.
Is there a name for this kind of UI component?

The only example that comes to my mind is a music equalizer. Although in my particular case, it has nothing to do with music.

I'm curious what approach I should take to illustrate this in a design document.
