Overview
Driving a full surround speaker layout with object-based audio, this Yamaha receiver is the control center of a home theater. It switches video sources over HDMI, calibrates the room with a microphone, and streams music over the network.
The reason to buy is a deep feature set in one chassis: wide format support, streaming services, a phono input and a second room. The limit is that the listing mixes up several fields, such as unit count and a stray special feature entry.
Who it's for
Home theater owners with a television that supports high dynamic range and a full speaker set will use the format support and room calibration. People with a simple two-speaker system, or who need a compact amplifier, will not use most of the features.
Pros and cons
- Object-based audio formats
- Room calibration included
- Many HDMI inputs
- Streaming services built in
- Unit count field looks wrong
- Power rating basis not stated
- Stray special feature entry
Performance notes
Room calibration measures the speakers with the supplied microphone and adjusts levels and timing for the space. The amplifier section sets how loudly the speakers can play, and the listed output power does not state its test conditions. Video passes through HDMI to the television.
