# Configure audio output

The Receiver service supports a maximum of 16 channels (8 stereo pairs) of embedding for any baseband audio output.

Before you start, ensure:

* At least one Receiver service is configured.

* A video service and at least 1 audio component is configured to be decoded.

## Add an output audio component

* From the Home page, select the required field.

* Select the RECEIVER item from the required feed then click .

* From the Parameters section, select Output to display options.

* Go to the Audio tab to open the tab and display options then select Add component. An audio component displays.

* Configure audio output parameters.
  Lipsync may be adjusted in the range +- 50mS. In low delay modes negative lip-sync adjustments may not be possible.

## Add all output audio

* From the Home page, select the RECEIVER item from the required feed then click .

* From the Parameters section, select Output to display options.

* Go to the Audio tab then select Add all. All the decoded audio components that are not currently included in the output audio configuration are added to the component column (up to a maximum number of embedded channels available for the output video format in use). Embedded channels are allocated in sequence until all available channels are filled.

## Delete an output audio

* From the Home page, select the RECEIVER item from the required feed then click .

* From the Parameters section, select Output to display options.

* Go to the Audio tab then click  in the Actions column. The audio component no longer displays.

## Delete all output audio

* From the Home page, select the RECEIVER item from the required feed then click .

* Go to the Audio tab then select Remove all. All the audio components are now removed from the list of output configurations.

## Configure Audio Embedding

* From the Home page, select the RECEIVER item from the required feed then click .

* From the Parameters section, select Output to display options.

* Go to the Audio tab then select a Component from the drop-down list. Available audio components are based on the audio being decoded for the service.

* Select an Embedding position from the drop-down list.

A single Embedded channel is required to output a stereo audio.

* 3 Embedded channels are required to output a 5.1 audio.

Each audio component is embedded into the output SDI at the selected position.
