This AV receiver is equipped with a variety of sound programmes that utilise Yamaha's original DSP technology. They allow you to easily create sound fields like actual movie theaters or concert halls in your room and enjoy natural stereoscopic sound fields. Now you can use the AV Controller app to adjust DSP parameters to your preference to match the type of music / movie or the mood you want to achieve. There are two modes, Basic and Advanced, that you can choose according to the type of adjustments you want to do.

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.

With the Spotify app on your smartphone, you've got instant access to millions of songs. And now you can stream those songs to your Yamaha system by using Spotify Connect.

HTC Connect™ lets you stream music to your AV receiver wirelessly. You don't need a separate app because HTC Connect™ is built right into your HTC phone. Simply swiping the HTC phone screen starts music output to the AV receiver, from the HTC device's local music sources or third party music sources.

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.

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.

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.

This AV receiver's HDMI input / output supports 4K Ultra HD video image pass-through. It also can perform 4K Ultra HD upscaling to boost a lower resolution image to super high-def resolution. This ensures compatibility with the latest super high resolution video formats. The latest version of HDMI supports 4K 50 / 60p input for expanding super high definition resolution 4K broadcasting.

MHL provides easy, direct connection of compatible mobile phones and this AV receiver. Playback of up to 1080p video and multi-channel audio from the phones is supported. The receiver also charges the connected phone. Play, Stop and other basic operations can be controlled from the remote control.

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 eight languages: English, French, German, Spanish, Italian, Russian, Japanese and Chinese, and can be displayed over both normal and 3D pictures.

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.

The Total Purity Concept, which Yamaha has been cultivating for many years, encompasses high drive amp technology, high purity pre-amplification, anti-vibration technology and independent pure power supplies. All models have a fully discrete power amplifier that helps to minimise distortion. They also adopt independent pure power supplies, allowing dedicated power supplies for the analogue and digital circuitry to prevent digital noise from affecting analogue circuitry. The anti-vibration heatsinks 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.

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 Normalisation, which varies the CINEMA DSP parameters according to the reflected sounds.

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 optimised to your system settings and listening environment.

Even when it is impossible to install surround speakers behind the listening position, Virtual CINEMA DSP reproduces virtual 7-channel surround sound filled with realism, from only two front speakers. The Virtual CINEMA FRONT feature lets you place two surround speakers and a centre speaker at the front to enjoy virtual 7-channel surround sound with even higher quality and resolution, as well as superior rear virtual sound localization. Adding two additional front presence speakers provides a three-dimensional sound field that gives you a feeling of its height and depth and of the vertical movement of the sound. You get more flexibility to arrange your speakers inside the room, along with easy enjoyment of high quality surround 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 3-dimensional sound without actual use of presence speakers.

Yamaha’ s exclusive low-range enhancement technology delivers richer bass than you expect from the speaker size while maintaining good localisation 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.

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.

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.

Yamaha’s new ECO mode reduces power consumption by about 20%. It can be set from the top of the GUI menu.
