How to perform transitions, using keys and key modifiers, memories and custom controls, as well as Media-Store operation.
Audio Mixer
The audio mixer node in DashBoard provides a graphical interface to all the audio sources and mixer layers. An audio channel must be routed to the switcher to be controllable by the audio mixer interface. Audio sources can come from the embedded audio on an input BNC, through the 1RU Audio Breakout Unit, or from the Media-Store.

To Configure Audio Outputs
Audio signals can be embedded in video both internal and external video outputs.

How to perform transitions, using keys and key modifiers, memories and custom controls, as well as Media-Store operation.
- Audio and Video Processing
  Video and audio signals are processed and passed through the switcher in different ways, depending on how the switcher is being used or is set up. A better understanding of how the switcher is processing these signals help you to achieve the production you want.
- Video Sources
  The switcher has access to three basic types of video sources; external, internal, and follows.
- Video Layering
  How video is layered in the output of the switcher depends on how an ME is re-entered onto the other, and what keyers are on-air for the ME.
- Video Preview
  Video preview allows you to use an additional monitor to preview what the next shot is going to be.
- Matte Source
  Matte color backgrounds (BG) are color signals that can be applied to backgrounds and keys. Color selection is done either by picking a preset color, or by adjusted hue, saturation, and luminance to create a custom color.
- Copying
  You can copy the content of an ME or keyer to another ME or keyer.
- Transitions
  Transitions are used to change the background video and take keys on and off-air. A transition can include any combinations of background and keyers for an ME, MiniME™, or MultiScreen. The background and each keyer can be transitioned independently.
- Keying
  Keying is the term used to describe when you insert (or electronically cut) portions of one scene into another, or place titles over background images. Keys are made up of two basic components, an alpha, that cuts the hole in the background video, and a fill, that fills the hole with different video.
- Memory Functions
  A memory register is a snapshot of the current state of the switcher that can include one or multiple ME, MiniME™, MultiScreen, or chroma key outputs. Up to 100 memory registers per ME, MiniME™, MultiScreen, or chroma key can be stored and recalled on the switcher. Each of these memory registers can store as little as the information of one ME, or as much as the current state of the entire switcher, including all ME, MiniME™, MultiScreen, chroma key outputs, Aux Buses, and DVE settings.
- Audio Mixer
  The audio mixer node in DashBoard provides a graphical interface to all the audio sources and mixer layers. An audio channel must be routed to the switcher to be controllable by the audio mixer interface. Audio sources can come from the embedded audio on an input BNC, through the 1RU Audio Breakout Unit, or from the Media-Store.

    - To Set the Number of Configurable Audio Faders (Channel)
      Set the number of audio faders, or channels, that the mixer has.
    - To Set Up Audio Faders
      Assign audio sources to each fader in the mixer.
    - To Assign Audio Channels to Mix Layers
      Select which audio sources are visible on each mixer layer.
    - To Configure the Analog Inputs
      Each analog input on the ABU can be configured independently.
    - To Configure the ABU Input Audio Delay
      Each input on the ABU can have an audio delay applied to it.
    - To Configure Audio Outputs
      Audio signals can be embedded in video both internal and external video outputs.
    - To Configure ABU Audio Outputs
      Audio signals are assigned to the outputs of each ABU as well as embedded in the video SDI-Audio loop.

- Switcher Sets
  The switcher stores configuration and operation data in a number of registers that contain the individual entries for items such as memories or personality settings. These registers can be stored as a single archive file, or as a register set that contains all the individual register of that type; all memories for example. These files are stored into Sets on a USB drive. Different Sets can be created for different shows or applications, allowing you to quickly locate and recall the switcher configurations.
- Media-Store
  The MediaManager interface to the Media-Store allows you to load stills, animations, or audio files and make them available across all MEs.
- Custom Controls
  Once programmed, a custom control (CC) can be played back by pressing a button. The custom control can be as simple as triggering an output GPI pulse, or as complex as recalling a specific memory register on an ME, performing a switcher transition, and selecting a group of keys.
- Sequencer
  The Sequencer allows you to create a playlist of custom control events.

To Configure Audio Outputs

Audio signals can be embedded in video both internal and external video outputs.

Click Navigation Menu > Configuration > Outputs and click Internal or External, depending on the output you want to configure.
In the Video + Audio section, click the Audio Mix button for the video output you want to assign an audio source to and select the audio source.

Tip: Assign audio channels to the SDI outputs used for the ABUs from the ABM page.
- Passthrough — embedded audio is passed through from the input source. Not available for MultiViewer outputs.
- Standard — embed all audio mixes from the internal audio mixer.
- Custom — select which audio source will be embedded on each stereo pair.
  - Silence — embed silence.
  - Main — embed the main audio mix from the internal audio mixer.
  - Monitor — embed the monitor mix from the internal audio mixer.
  - Aux X — embed the audio from Aux Bus X.
Click Internal and then click the Audio Mix PC Audio button and select the audio source you want to assign to the PC Audio output.
