# Behringer X Air

> Control Behringer X Air and M Air compact mixers over OSC — channel and main faders, mutes, aux sends, mute groups and snapshots — with live state and triggers.

The **X Air** device controls [Behringer X Air and M Air](https://www.behringer.com/) compact digital mixers, so a rundown item can open a presenter's microphone, duck a bed, or recall a snapshot for the next segment.

For the larger consoles, see [Behringer X32](/devices/behringer-x32).

## Connection

Provide the mixer's **host** and **UDP port** (default **10024**), and pick the **model** — XR12, XR16, XR18, or X18.

## Commands

| Command               | What it does                                         |
| --------------------- | ---------------------------------------------------- |
| Set channel fader     | Sets an input channel's fader level, from 0.0 to 1.0 |
| Mute / unmute channel | Mutes or unmutes an input channel                    |
| Set main fader        | Sets the main LR fader level                         |
| Mute / unmute main    | Mutes or unmutes the main LR bus                     |
| Set send level        | Sets a channel's send level to a bus or aux          |
| Set mute group        | Mutes or unmutes one of the four mute groups         |
| Recall snapshot       | Recalls a stored snapshot by index                   |

A raw OSC command is available for anything not listed here.

<Tip>
  A **mute group** changes several channels in one message. Muting a group of microphones that way avoids the ragged effect of separate rule actions arriving a few milliseconds apart.

## Triggers

| Trigger               | Fires when                                                            |
| --------------------- | --------------------------------------------------------------------- |
| Connection changes    | The mixer connects or disconnects                                     |
| Channel mute changes  | A channel is muted or unmuted, carrying the channel and its new state |
| Channel fader changes | A fader moves, carrying the channel and level                         |

Because mute and fader changes fire whoever made them, a rule can react to an operator moving a fader on the console itself — not only to changes Fabl made.

## State

The device reports its connection state.
