# Adjusting Parametric Beam parameters

You can adjust the following parameters from the Properties Panel:

| Parameter          | Type of Interaction | Function                                                                                                                                                                                        |
| ------------------ | ------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Type               | dropdown            | Defines the beam or Virtual Source type. Here, choose Parametric Beam.                                                                                                                          |
| Audio Channel      | dropdown            | Selects the corresponding audio channel from your Dante Controller that you would like to route to a beam. If desired, the same audio channel can be routed to multiple beams at the same time. |
| Performance Target | slider              | Adjusts the trade-off between sound level output and dispersion uniformity.                                                                                                                     |

You can adjust the following directivity parameters from the right side of the Properties Panel:

| Parameter       | Type of Interaction | Function                                                                                                   |
| --------------- | ------------------- | ---------------------------------------------------------------------------------------------------------- |
| Opening Angles  | field               | Sets the horizontal (H) and vertical (V) angles to define the size of the addressed area.                  |
| Steering Angles | field               | Sets the horizontal (H) and vertical (V) angles to define the direction in which the most energy is needed |
