Denon HEOS – Review and Tutorial
Once you've downloaded and installed the HEOS app on a compatible smartphone, select Set Up Now. The app will find and pair any HEOS-compatible devices you may have.
Once setup, you can use your smartphone to stream music to compatible HEOS devices via Wi-Fi or Bluetooth, no matter where the devices are in your home. You can also use the HEOS app to stream music to the receiver. You can listen to music through your home theater system or stream music sources connected to the receiver to other HEOS wireless speakers.
HEOS can stream music from Amazon Music, Pandora, SiriusXM, SoundCloud, Spotify, and TIDAL. In addition to music streaming services, you can use HEOS to access and distribute music from content stored locally on media servers or PCs.
