![](https://support.audeara.com/hs-fs/hubfs/image-png-Sep-21-2026-03-56-28-4982-AM.png?width=670&height=254&name=image-png-Sep-21-2026-03-56-28-4982-AM.png)

 **Legend**  
**A:** Digital Optical Output port (PA System)  
**B:** Audio IN: SPDIF / AUX port (Audio Broadcaster)  
**C:** USB-C Power port (Audio Broadcaster)  
**D:** Provided Digital Optical (SPDIF) Cable  
**E:** Provided USB-C Power Cable 

 **Please note:** The audio signal sent through the Digital Optical Output stays at a consistent level, regardless of the PA system’s speaker volume setting. You can adjust the PA system’s speaker volume without changing the audio level being sent to the Audio Broadcaster. To adjust the volume for listeners connected to the Audio Broadcaster, please use the **volume controls on their individual listening devices**. 

**PA system audio settings**  
In most cases, audio will be sent through the PA system's Digital Optical Output automatically once connected. 

If you do not hear audio through the Audio Broadcaster, check the PA system's audio settings and ensure the **Digital / Optical (S/PDIF) Output is enabled** and the **Digital Audio Format is set to PCM or Stereo PCM**.

 **Please note:** Settings and terminology vary between PA system models. If you're unsure, refer to your PA system's user manual for its Digital Optical / S/PDIF output settings.
