HEOS-enabled AV receivers connect to your home network so you can stream music from supported services and share it with compatible speakers in other rooms. The HEOS app lets you group rooms for synchronized playback or choose different music for separate spaces, helping extend the AV receiver beyond the main listening area.

HEOS-enabled AV receivers support configurations ranging from two-channel stereo and 5.2 surround to 5.2.2, 7.2, 9.4, 11.4, and larger immersive layouts up to 9.4.6, depending on the receiver. HEOS also lets you stream music to compatible speakers in other rooms while the receiver powers the main home theater system.

HDMI inputs and outputs determine which sources, displays, and video formats an AV receiver can connect to, with these Denon HEOS AVRs supporting configurations that range from 4K to 8K video, HDR formats, and gaming features on select models. Audio return channel (ARC) and enhanced audio return channel (eARC) send TV audio back to the receiver through the HDMI connection, with eARC supporting higher-bandwidth audio formats such as Dolby TrueHD, DTS-HD, and Dolby Atmos.

When comparing Denon HEOS-enabled AV receivers, look for a guided setup assistant, automatic speaker measurements, and Audyssey room-correction tools that help tune audio to your room. For more advanced installations, compare channel configuration flexibility, preamplifier options, and support for higher-level calibration such as Audyssey MultEQ XT32 or an optional Dirac Live upgrade.
