What to do if Denon Speakers show 'Device was not found'?

  If you receive a “Device was not found” message, the speakers and controller device might not be on the same network. Try moving the speaker closer to your wireless router. Also, verify that the controller device is on the same network as your speakers and ensure no other electronic devices are interfering with your wireless network signals. If the speakers are far from the router, consider adding a Wireless Range Extender like the HEOS Extend. If your wireless router is incompatible with the HEOS speaker, use the optional HEOS Extend Wireless Range Extender and hard-wire it to your router.

  If your music cuts out or delays, ensure your internet connection is working correctly and that your speakers are within range of your wireless network. Also, make sure your speakers aren't near other electronic devices that could interfere with wireless connectivity.

Why is there a delay when using AUX Input on Denon Heos 7 Speakers with my TV?
- A
  Amber HarmonAug 16, 2025
  The HEOS system buffers audio before sending it to the speakers to ensure simultaneous arrival. If you're connecting the AUX input with your cable or satellite box to enjoy TV audio through multiple HEOS speakers, you might notice a delay. You can avoid this delay by listening only to the speaker directly connected to the set-top box.
