Overview
An eleven channel processing engine with nine built in amplifiers drives this Yamaha receiver, decoding Atmos, DTS:X and Auro for big immersive layouts. Every HDMI input carries top tier video, and three outputs feed a TV, projector or second zone.
Full bandwidth HDMI on all inputs means no juggling which console goes where, and three outputs cover complex rooms. Two more channels need an external amplifier to use the full processing.
Who it's for
Enthusiasts building large immersive layouts and multi zone homes. Casual movie watchers will not use most of what it offers.
Pros and cons
- Every HDMI input at top spec
- Three HDMI outputs
- Auro-3D plus Atmos and DTS:X
- Advanced 3D room calibration
- Very large and heavy
- External amp needed for full channel count
- Sonos Port sold separately
Performance notes
Calibration with three dimensional measurement and precision EQ shapes how well height speakers and bass integrate in a real room. Surround:AI adapts effects in real time by scene. Driving the full processing count requires adding external amplification for the extra channels.
