# 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

1. From the **Home** page, select the required field.

2. Select the **RECEIVER** item from the required feed then click `Edit`.

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

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

5. Configure audio output parameters.

   > **Info:** Lipsync may be adjusted in the range +- 50mS. In low delay modes negative lip-sync adjustments may not be possible.

## Add all output audio

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

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

3. 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

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

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