# Preview

There are two types of Preview panels that you can add to your Switcher Pages:

* **Preview**: The input buttons are the same size as all other buttons.
* **Preview (Wide Input)**: The input buttons are wider than normal for easier tapping.

This panel lists all sources that you can place on the preview bus.

### M/E Preview Panels

If you have an ATEM switcher that has multiple Mix Effects Buses, you can add Preview panels for each individual Mix Effect Bus. They will be listed in the Edit/New Switcher Page section as:

* M/E 1 Preview
* M/E 2 Preview
* M/E 3 Preview
* M/E 4 Preview

The normal Preview panel operates on the currently selected Mix Effects Bus.
