Total Purity Concept for the Finest Sound Quality
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.
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 Buttons with the Ability to Preset Songs and Stations

The inputs can be set to specific sources, such as an FM or Internet radio station, a station on a streaming service, a USB device or a song on a PC or NAS (network). Once you have set the buttons, simply press one on the main unit or the remote control to power on the receiver and hear your desired music. The buttons can be re-set at any time.
Virtual Presence Speaker and Virtual Surround Back Speaker
The Virtual Presence Speaker function makes full use of centre and surround speakers to create virtual presence speakers. Enjoy CINEMA DSP 3D Mode surround sound even in environments where speaker installation is limited. In addition, this model also features a Virtual Surround Back Speaker function. Even without using surround back speakers, you can experience more natural sound from behind you.
Virtual CINEMA FRONT Provides Virtual 7-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 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 localisation. 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.
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.
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.
With an advanced energy saving design, this AV receiver achieves a low power consumption of not more than two watts when in Network Standby mode.
