This page / section pertains to **BrightAuthor Classic**, our legacy app. **BrightSign Author **is our latest app for managing content and players.

Development of BrightAuthor Classic has largely ceased and the app will eventually be deprecated and replaced with BrightSign Author.
:::

You can change the audio output settings (e.g., analog, HDMI, SPDIF) for a BrightAuthor Classic project in **Zone Properties**:

1. Select the Video Only, Video or Images, Audio Only, or Enhanced Audio zone you wish to edit in the **Edit > Playlist** tab (see the image below).
2. Select **Zone Properties**.
3. **Audio Output**: Select the output(s) the zone should use (SPDIF output is not available on all models). For **HDMI/SPDIF**, select if the audio should be output as **Pass through** or **Stereo**:
   - **Pass through**: Supplies the un-decoded audio signal through the connector. Use this option if the zone audio (for example, AC3 Dolby Digital) is being decoded on an external device.
   - **Stereo**: Supplies the decoded audio signal through the connector.
4. Change the following options (optional):
   - **Audio Mixing**: Send the **Left** signal, **Right** signal, or the full **Stereo** signal.
   - **Initial volume (Audio)**: Set the initial volume for audio files (0-100).
   - **Initial volume (Video)**: Set the initial volume for video files (0-100).
   - **Minimum Volume**: Set the minimum volume for the zone (0-100).
   - **Maximum Volume**: Set the maximum volume for the zone (0-100). This setting can be overridden by other volume settings in a presentation, including the **Initial Volume** setting for the zone and volume commands attached to events or states.
   - **Fade (in seconds)**:(Enhanced Audio zones only) Specify the duration of cross-fading between audio files, as well as the fade in and fade out duration at the beginning and ending of a playlist.
