Yamaha Compressed Music Enhancer is now optimised for Bluetooth audio transmission to ensure that your music will have vivid, lively sound quality even during wireless playback.
4K Ultra HD Full Support with 4K60p, HDCP2.2, HDR Video and BT.2020 pass-through
This AV receiver completely supports with the latest HDMI® standards. Thanks to transmission of 4K video at 60 frames per second pass-through, you can fully enjoy the high definition video quality of 4K without degradation. It also adheres to the HDCP2.2 copyright protection standard for 4K video transmission. It also supports HDR (High Dynamic Range) Video which provide enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. Furthermore it supports wider colour gamut of BT.2020 pass-through.
HDMI with 3D and Audio Return Channel
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.
Discrete Amp Configuration for High 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.
AV Setup Guide App Makes System Setup Easier

AV Setup Guide is an app that makes it much easier to perform receiver setup, and also assists you with cable connections between the AV receiver and source devices. It guides you through various settings such as speaker connections, TV and source device connections and power amp assignment. System illustrations and actual AV receiver images help you understand how to make the connections between devices, for much quicker system setup. It is available in multiple languages. Designed for iOS and Android tablet.
SCENE for One-Touch Start
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.
HDMI CEC for Easy Operation

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™ Sound Optimisation for Automatic Speaker Setup
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.
HD Audio with CINEMA DSP

Yamaha’s exclusive CINEMA DSP technology supports playback of HD Audio (Dolby TrueHD, DTS-HD Master Audio, etc.), providing natural and expansive sound imaging.
Virtual CINEMA FRONT Provides Virtual 5-channel Surround Sound with High Quality and Resolution
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.
Extra Bass Provides Rich Bass Reproduction, Even with Small 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.
Compressed Music Enhancer
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.
Subwoofer Trim for 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 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.
ECO mode Lowers Power Consumption by 20%*
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).
Selectable Auto Power Standby
Auto Power Standby lets you save energy by selecting to turn off the power after 20 minutes, 2, 4, 8 or 12 hours.

CINEMA DSP Digital
・ Since the Dolby Surround and DTS systems were originally designed for use in movie theaters, their effect is best felt in a theater having many speakers designed for acoustic effects. Since home conditions, such as room size, wall material, number of speakers, and so on, can differ so widely, it is inevitable that there are differences in the sound heard. Based on a wealth of actually measured data, Yamaha CINEMA DSP provides the audiovisual experience of a movie theater in the listening room of your own home by using the Yamaha original sound field technology combined with various digital audio systems.
・ The actually measured sound field data contains the information of the height of the sound images. CINEMA DSP 3D mode achieves the reproduction of the accurate height of the sound images so that it creates the accurate and intensive stereoscopic sound fields in a listening room.
YPAO Automatic System Calibration
Yamaha’s YPAO system uses a small microphone and sophisticated equalization to automatically set the best sound for any room, no matter where the speakers are. First it checks the speaker connections and phase of each speaker. Then it sends out tones which are captured by the microphone to analyze the room acoustics and sets a variety of parameters, such as the speaker size, the distance of the speakers and even the sound pressure level, etc. Until it achieves the best sound conditions for your room and you don't have to do anything!
4K Pass-Through
4K Pass Through receives super high-def resolution video and pass it to a 4K compatible monitor.
This ensures compatibility with the latest super high resolution video formats.
SCENE – A NEW LEVEL OF OPERATING EASE
With most AV components, watching or listening to what you want requires a number of steps. You have to turn on the AV component, turn on another component like a DVD player, select the source, select the surround mode and then press play. But with Yamaha’s SCENE feature all you need to do is press one button. Both components turn on, the correct DSP setting is made, and play begins. This SCENE function allows you to change input sources and sound field programmes with one button. Four SCENE buttons are available for different usages, such as playing movies or music.
Compressed Music Enhancer
Yamaha employs sophisticated digital signal processing with exclusive algorithms to enable playback that improves the performance of compressed music formats, including MP3 and WMA. With the Compressed Music Enhancer, highs and especially lows are richer and smoother, bringing music back to life to be as close to the original as possible.
SILENT CINEMA
Yamaha has developed a natural, realistic sound effect DSP algorithm for headphones. Parameters for headphones have been set for each sound field so that accurate representations of all the sound field programs can be enjoyed on headphones.
ECO mode
ECO mode reduces power consumption by about 20%*. It can be set easily from the top of the GUI/OSD menu.
*Compared to power consumption when ECO mode is off. (Yamaha measurement).
HDMI
HDMI (High-Definition Multimedia Interface) is the first industry supported, uncompressed, all-digital audio/video interface. Providing an interface between any source (such as a set-top box or AV receiver) and an audio/video monitor (such as a digital television), HDMI supports standard, enhanced or high-definition video as well as multichannel digital audio using a single cable. HDMI transmits all ATSC HDTV standards and supports 8-channel digital audio, with bandwidth to spare to accommodate future enhancements and requirements. When used in combination with HDCP (High-bandwidth Digital Content Protection), HDMI provides a secure audio/video interface that meets the security requirements of content providers and system operators.
