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, which also charges when connected. Because the digital signal from the iPod / iPhone 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 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.

This AV receiver provides advanced HDMI features including pass-through of 4K Ultra HD, which is gaining popularity. 4K Ultra HD refers to four times the resolution of a 1080p display. This receiver is capable of passing the 4K Ultra HD data from the source to the monitor, for image clarity far beyond present standards.

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.

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.

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.

YPAO analyses the room acoustics and adjusts various audio parameters for optimum sound in just a few minutes. It’s like having a professional installer calibrate your system.

Even when it is impossible to install surround speakers behind the listening position, Virtual CINEMA DSP reproduces virtual 5-channel surround sound filled with realism, with only two front speakers. With Virtual CINEMA FRONT, you will enjoy virtual 5-channel surround sound with higher quality and resolution by installing surround speakers at the front. 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.

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.

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.

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.

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.
