Denon Home 400 Wireless Speaker

Denon Home 400 Wireless Speaker

The Denon Home 400 is a wireless speaker for home music systems. Built-in amplifiers and drivers allow music playback without a separate amplifier. The HEOS app selects music sources and controls a multiroom system.

Wi-Fi provides playback from network sources and compatible services, AirPlay 2 streams from Apple devices, and Bluetooth connects a phone. The AUX input accepts a wired audio source, while USB connects music storage.

Two speakers of the same model can form a stereo pair. Group the speaker with other HEOS devices, add a compatible wireless subwoofer, or use a pair as rear channels for a Sound Bar 550 system. Additional devices are sold separately.

Voice features are activated in the app; microphones can be disabled. Siri requires a HomePod or HomePod mini on the same network; service and voice-feature availability depends on region. A USB-C Ethernet adapter is not included.
