This AV receiver's HDMI input/output supports 4K video image pass-through. It also can perform 4K upscaling to boost a lower resolution image to super high-def resolution. This ensures compatibility with the latest super high resolution video formats.

3D means the receiver can handle 3D signal data. The Audio Return Channel function enables data to be sent and received via the same HDMI cable, so you can hear the sound from the TV via a single HDMI cable, with no need for an extra optical cable.

In ordinary deinterlacing, pixels in areas of movement are interpolated by upper and lower ranges. This causes jaggies in diagonal lines. Edge adaptive deinterlacing detects the direction of the line and interpolates the pixels optimally.

• 4K / full HD 1080p video upscaling from analogue and HDMI input
• Supports Deep Colour (30/36 bit), x.v.Colour, 24 Hz Refresh Rate and Auto Lip-Sync compensation

This AV receiver provides a variety of network functions that enable you to access more sources and also enhance operation. You can connect the receiver to a PC to enjoy Internet Radio and operate your system via Web Browser Control. The AV Controller app (from iTunes App Storeor Android Market) lets you control various functions from your iPod, iPhone, iPad or Android phones.

This AV Receiver lets you use the Yamaha AV Controller app that is downloadable from the iTunes App Store or Android Market to control power on/off and volume, select input and DSP modes and operate other functions from an iPod, iPhone, iPad or Android phones. A tablet version is also available.

This AV receiver supports AirPlay, which means they can accept wireless music streaming from iPod touch, iPhone or iPad, as well as from iTunes on Macs or PCs. This makes it easy to enjoy music from your mobile devices or computer on your home theatre system. You can use view metadata such as song title, artist name as well as album art* via AV receiver's on-screen display.
*Some models don't support album art display.

A USB port on the front panel allows convenient connection of an iPod/iPhone/iPad, which also charges when connected. Because the digital signal from the iPod/iPhone/iPad is transmitted directly to the AV receiver, there is no signal loss or interference, so you enjoy the best possible sound quality. In addition, you can use the receiver’s remote control unit to operate the iPod/iPhone/iPad music playback functions.

YPAO-R.S.C. analyses room acoustics and measures various speaker characteristics, then calibrates audio parameters to achieve optimum sound. 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.

Yamaha’s latest Graphical User Interface 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 seven languages: English, French, German, Japanese, Russian, Spanish and Chinese, and can be displayed over both normal and 3D pictures.

Intelligent Amp Assign automatically assigns amplifier channels to certain speakers, depending on what functions are selected. For example, in a 7.1-channel system, when Zone 2 is off, all 7.1 channels will be used in the Main Zone. However, when Zone 2 is on, power to the two Surround Back channels will be directed 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 receiver—one more way Yamaha makes your life a little easier.

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

In addition to the large number of HDMI inputs on the rear panel, there is also one on the front panel. This gives you a convenient way to quickly plug in a digital camera or camcorder for highest quality pictures.

Another benefit of HDMI is the availability of CEC functionality. When the unit is connected to a CEC compatible TV, it will turn on and off together with the TV, and you can use the TV remote to control the volume. CEC also provides advanced functionality with other
components. For example, you can use the receiver’s remote unit to control player functions like Skip and Stop.
＊All connected devices must be HDMI CEC compatible. Some CEC compatible TVs/players may not work.

When the AV receiver is in HDMI Standby Through mode, the input source (Blu-ray™ Disc player, game console, etc.) for viewing on the monitor can be changed via the remote control. There’s no need to turn on the AV receiver in order to switch sources.

• Charging of iPod, iPhone and iPad via USB when AV Receiver is off
• iPod/iPhone song titles displayed in English and Western European languages on the front panel and on-screen display
• Audio input assign capability for HDMI and component video input
• Audio Delay for adjusting Lip-Sync (0-500 ms)
• Newly designed preset remote unit
• Background Video feature (for tuner and Net)

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 3-dimensional sound without actual use of presence speakers.

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

Dialogue Lift raises the sound of dialogue from the centre speaker to a position in the centre of the screen. Newly developed virtual dialogue lift achieves dialogue lift function even without the need for presence speakers. Dialogue Level Adjustment lets you control the volume of the vocal sound, so you hear movie dialogue and music vocals at the ideal level for clear, comfortable listening.

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

Adaptive DRC automatically adjusts the dynamic range of the sound according to the volume level. This ensures that you hear clear dialog and vocals, and all sound effects at comfortable levels. There is no need to adjust the volume level as you listen; everything from whispers to big explosions will be heard clearly and comfortably at the same volume setting. It also tones down loud TV commercials, and is ideal for low-volume, late-night listening, when you do not want to disturb others.

• Virtual dialog lift even without use of presence speakers
• Virtual Presence Speaker function for CINEMA DSP 3D surround without Front Presence Speakers
• SILENT CINEMA and Virtual CINEMA DSP

• Zone 2 on/off and control on front panel
• Zone sleep and system sleep
• Remote input/output
• Programmable +12V trigger output

Yamaha’s new ECO mode reduces power consumption by about 20%. It can be set from the top of the GUI menu.
* Compared to power consumption when ECO mode is off (Yamaha measurement).

Auto Power Down lets you save energy by selecting to turn off the power after 2, 4, 8 or 12 hours.

Yamaha makes its receivers eco-friendly with a low standby power consumption of 0.1W in IR Standby mode (3W in HDMI Standby Through mode, 2W in Network Standby mode).
