# 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 |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.holoplot.com/holoplot-plan/working-with-beams/creating-a-parametric-beam/adjusting-parametric-beam-parameters.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
