Overview
Powering a full multi-speaker surround layout, this receiver automatically measures the room through YPAO calibration and adjusts levels and distances before the first movie plays. Voice commands through a connected Alexa device can then switch inputs or adjust volume without the remote.
Home theater owners running a full surround speaker set get automatic calibration, Alexa voice control, and multiroom streaming without buying separate hardware for each. MusicCast works best when other Yamaha or MusicCast-enabled speakers are already in the house, since a single unit alone will not deliver the multiroom benefit. HDMI switching covers most modern sources without needing an external splitter.
Who it's for
Households building a dedicated surround sound room with several speakers and an Alexa device already in use get the most from this receiver. Anyone with a simple two-speaker setup or no interest in voice control should look at a smaller model.
Pros and cons
- YPAO calibration sets levels automatically
- Works with Alexa for voice control
- Six HDMI ports cover most modern sources
- MusicCast enables multiroom audio streaming
- Multiroom benefit depends on owning other MusicCast gear
- Alexa device sold separately, not included
- Full channel count needs a complete speaker set
Performance notes
YPAO calibration runs a test tone through each connected speaker and a supplied microphone, then adjusts channel levels, distances, and crossover points to match the room before normal playback starts. Voice commands route through a paired Alexa device rather than a microphone built into the receiver itself, so response depends on that device's own connection.

Frequently asked questions
Does the RX-V679BL work with existing MusicCast speakers?
Yes, it joins any existing MusicCast-enabled speakers or sound bars on the same network for synchronized multiroom playback.
Is an Amazon Echo or Alexa device included?
No, an Alexa-enabled device must be purchased separately and paired to it for voice control.
Can it drive a smaller speaker layout instead of the full surround set?
Yes, the extra channels can be left unused or repurposed for a second zone if a full surround layout is not being run.
Will it work with a curved or ultra-wide display?
Video passthrough is display-agnostic since it simply forwards the HDMI signal, so curved or ultra-wide screens work as long as they accept a standard HDMI input.
