:::hint{type="warning"}
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.
:::

Enhanced Audio zones provide similar functionality to Audio Only zones, but allow cross-fading between audio files in the playlist: Fading occurs from silence at the beginning of the audio playlist and to silence at the end of the audio playlist, while cross-fading occurs between audio files.

:::hint{type="danger"}
Cross-fading will not work between audio tracks if they have different sampling rates (for example, if the first file is sampled at 48kHz and the second is sampled at 44kHz).
:::

Use the **Zone Properties** window of an Enhanced Audio zone to edit the following. Note that **Analog Stereo **and **SPDIF **outputs are only available on certain player models.

- **Audio Output**: Configure audio outputs for the zone.> \[!WARNING]
- **Analog Stereo**: Check this box to enable audio output via the 3.5mm audio connector (or USB Type C connector on the LS423).
- **HDMI**: Check this box to enable audio output via the HDMI**®** connector. 
  - **Pass through**: Supplies the un-decoded audio signal through the HDMI 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 HDMI connector.
- **SPDIF**: Check this box to enable audio output via SPDIF.
  - **Pass through**: Supplies the un-decoded audio signal through the SPDIF 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 SPDIF connector.
- **Audio Mixing**: Choose the mixing of the audio output:
  - **Stereo**: Outputs both left and right audio signals.
  - **Left**: Outputs the left audio signal only.
  - **Right**: Outputs the right audio signal only.
- **Initial Volume**: Set the initial volume for audio files (0-100).
- **Minimum Volume**: Sets the minimum volume for audio files (0-100).
- **Maximum Volume**: Sets the maximum volume for audio files (0-100).

:::hint{type="warning"}
The Maximum Volume setting will 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)**: Sets the duration of cross-fading between audio files, as well as the fade in and fade out durations at the beginning and ending of a playlist.
