Cinema 50

The Marantz Cinema 50 is a 9.4 channel 8K AV receiver rated at 110W per channel, with Dolby Atmos and six HDMI inputs. The local denonavr integration controls it as a media_player, covering power, volume, input selection, and sound mode.

Protocols
Roles it can fill
A nine channel receiver for dedicated theaters and large media rooms. In Home Assistant, Marantz is a virtual brand that resolves to the local denonavr integration, which uses Telnet push on port 23 with an HTTP fallback. Set Network Control to Always On, labeled Network Standby on some models, so Home Assistant can power the receiver on from standby. It is the default on recent models and raises standby power draw. The receiver accepts a single Telnet control connection, so a Control4, Crestron, Savant, or RTI system already on port 23 locks Home Assistant out. The Marantz phone app talks to the HTTP web control interface and does not take that slot. The Cinema 50 also appears through HEOS, so both integrations create a media_player. Keep both and combine them with a Universal Media Player: denonavr carries power, zones, and sound mode, while HEOS carries album art, metadata, and media browsing.
