You can connect the AV receiver to your home network or internet to enjoy Internet radio, Spotify, Pandora® or music stored on a NAS and home PC. The AV Controller App (from iTunes® or Google Play) lets you control various functions from your iPod®, iPhone®, iPad® or Android™ phones/tablets.


Wi-Fi Compatible

Stream simply. Built-in Wi-Fi allows for a connection with your wireless router, greatly simplifying system connections for enjoying networked audio (PC/NAS) and music streaming services. If a Wi-Fi router is not available, the unique Wireless Direct feature not only allows you to stream music directly from your smartphone or tablet via the AV Controller App, AirPlay® etc., but also allows for control of the AV receiver as well.




iCompatible. This AV receiver supports AirPlay, which means it can accept wireless music streaming from iPod, iPhone, iPad, as well as from iTunes on a Mac® or PC.

Hear more. When music is encoded into a digitally compressed format like MP3, the frequency response suffers. The Compressed Music Enhancer from Yamaha employs sophisticated digital signal processing using exclusive algorithms to restore what was lost, so the music always sounds the way it should.

Gapless Playback

No interruptions. Many live and classical albums have no gaps in the music. Gapless playback ensures that there are no pauses between audio files. This provides playback with no interruptions, the way it was meant to be heard. 

Compatible with WAV, FLAC and ALAC file formats, and input from USB/PC/NAS.



Keep collecting. Enjoy music from your vinyl collection through the phono input terminals.


YPAO™ - R.S.C. with Multipoint Measurement

Advanced sound optimization. YPAO - Reflected Sound Control analyzes room acoustics and measures various speaker characteristics, then calibrates audio parameters to achieve optimum sound in the listening area. It employs Reflected Sound Control to correct early reflections for studio-quality sound. It also provides DSP Effect Normalization which varies the CINEMA DSP parameters according to the reflected sounds. With multipoint measurement, measure up to eight locations ensuring each seat is acoustically optimized during playback.


YPAO™ Volume

Hear everything low. Human ears have less sensitivity to high and low frequencies, especially at lower volumes. YPAO Volume applies loudness EQ correction to automatically adjust high and low frequency levels as volume changes. Using the YPAO measurement results, EQ correction is optimized to your system settings and listening environment.


Rich Bass Reproduction

Feel your lows. This exclusive low-range enhancement technology delivers richer bass than you would expect from smaller sized speakers while maintaining good localization and sound balance even with compact front speakers. When a subwoofer is used, it improves the volume of the entire low range of the speaker system, not only the front speakers, but also enhancing the bass from the subwoofer. You'll enjoy video and music with sound that has exceptional power and presence.


Total Purity


Enjoy fine sound quality. The Total Purity Concept, which Yamaha has been cultivating for many years, encompasses high drive amp technology, high purity preamplification, anti-vibration technology and independent pure power supplies. All models have fully discrete power amplifiers that help minimize distortion. They also adopt pure independent power supplies, allowing dedicated power supplies for the analog and digital circuitry to prevent digital noise from affecting analog circuitry. The anti-vibration heat sinks are designed to suppress vibration from transistors and sound pressure. Independent power supplies for the DACs are designed to further eliminate noise on certain models. Down to every detail, these AV receivers are designed with full emphasis on the highest possible sound quality.

Discrete Amp Configuration


Enjoy quality sound. This AV receiver was designed with a strong focus on achieving exceptionally high sound clarity. It employs a discrete amp configuration and a low-jitter PLL circuit, which contribute to its excellent audio performance.

SCENE for One-Touch Start


Ready, set, go. Pressing a SCENE button powers on the AV receiver and selects the input source and DSP mode. You can reset the buttons for different sources by selecting a source and DSP mode, then pressing a SCENE button for more than three seconds.

Virtual Presence Speaker


Wide, high and dense sound. CINEMA DSP 3D provides a wide, high and dense sound field. HD Audio format decoding lets you enjoy HD Audio sources. Virtual Presence Speaker delivers three-dimensional sound without the actual use of presence speakers.

Virtual Surround Sound

Surround from the front. Even when it is impossible to install surround speakers behind the listening position, you will enjoy virtual 7-channel surround sound with all of the speakers placed in the front of the room. This is ideal for those who can't or prefer not to install speakers in the rear of the room.


Virtual Presence Speaker and Virtual Surround Back Speaker


Virtually surround yourself. With the power of CINEMA DSP 3D, the Virtual Presence Speaker function makes full use of center and surround speakers to create audible information from where presence (height) speakers are normally installed. In addition, this model also features a Virtual Surround Back Speaker function. Even without using surround back speakers, you can experience more natural, lifelike sound from behind you without physical speakers being installed in the surround back area of the listening environment.

Subwoofer Trim


Improved sound imaging. The Subwoofer Trim Control enhances the low frequencies by avoiding overlap with the front speaker output. This will result in a cleaner, more focused soundstage while providing a seamless frequency response. When subwoofer frequency overlap occurs in conventional systems, the overall sound is “pushed” toward the subwoofer. Subwoofer Trim Control takes care of this by separating the low subwoofer frequencies cleanly, thus stabilizing the front stage while providing a well-balanced enhanced bass sound

Intelligent Amp Assign

Intelligent design. Intelligent Amp Assign automatically assigns amplifier channels to certain speakers, depending on what speaker layout is selected. For example, in a 7.1-channel system, when Zone 2 is turned off, all 7.1-channels will be used in the Main Zone. However, when Zone 2 is powered on, the power to the two surround back channels will automatically be redirected to the two speakers in Zone 2 and the Main Zone will receive 5.1-channels of power. Similarly, when CINEMA DSP 3D is on, the two Front Presence speakers will be powered and not the two surround back speakers. When CINEMA DSP 3D is off, this situation is reversed. Thanks to Intelligent Amp Assign, there’s no need to switch the speaker cables on the rear of the AV receiver.


Advanced Graphical User Interface

Multilingual user interface. The latest graphical user interface from Yamaha has a high-resolution display with clear, easy-to-use menus and also includes a selectable status bar that shows input source, volume level, DSP mode and audio format. The GUI provides a choice of eight languages: English, French, German, Spanish, Italian, Russian, Japanese and Chinese and can be displayed over both normal and 3D pictures.




Install with ease. The AV SETUP GUIDE makes it much easier to perform the set up process with the Yamaha AV receiver. This app assists you with cable connections between the AV receiver and source devices. Additionally, it guides you through various settings such as speaker connections, TV and source device connections and power amplifier assignments. System illustrations and actual AV receiver images help you understand how to make the connections between devices. It is available in multiple languages and is designed for iOS and Android tablets.

Selectable Standby


Be lazy. Auto Power Standby lets you save energy by selecting to turn off the power after 20 minutes, 2, 4, 8 or 12 hours.

ECO Mode


Go Green. When ECO mode is turned on it can reduce power consumption by about 20 percent. 

*Compared to power consumption when ECO mode is off (Yamaha measurement).

Easy Setup


Go smart. Use your smartphone or tablet together with the MusicCast app to operate the speaker and change settings quickly and easily. The app also functions as a remote control for all your MusicCast devices.
