ATEM Advanced Panels open up the power of your ATEM Constellation because they give you an enormous amount of control, allowing you to setup more complex effects. It's also a nicer way to work because you have physical broadcast quality buttons, knobs and a t‑bar fader so you can access all features in the switcher, all at the same time. Imagine using the 4 M/E model to access all M/Es simultaneously, with an input button for every single SDI source on the ATEM Constellation switcher!
