Enter a New World of Sound with Dolby Atmos® and DTS:X™
These sound technologies transport you from an ordinary moment into an extraordinary experience with captivating, multidimensional sound that fills your room with amazing richness and depth. These sound technologies allow for music, people and objects to come alive in breathtaking detail and flow in precise choreography all around you, making you feel like you are right in the middle of the story.
Speaker Layout Patterns Designed for Dolby Atmos Playback
Yamaha provide multiple placement patterns for presence speakers that support Dolby Atmos, creating a sound field that’s ideal for your setup. Any layout can be appropriately reproduced, including the three-dimensional space of CINEMA DSP as well as Dolby Atmos.
AVENTAGE AV Receivers: Designed to Deliver the Highest Levels of Audio Performance
The AVENTAGE line of high-performance AV receivers is based on the audio design concept of providing a massive, full-bodied sound for movie sound effects and the accurate reproduction of music sources. By expertly harmonising traditional and advanced technologies, every factor that affects sound quality, from materials and parts to construction, layout, vibration damping (unique foot) and “fine-tuning” the sound, is handled with no other thought than to achieve the best possible audio quality. As a result, every AVENTAGE model has the ability to reproduce the most subtle details of high-definition sound, so that listeners can enjoy a truly high-class sound studio experience at home.
Anti Resonance Technology Wedge Helps to Ensure that Vibrations Do Not Affect Sound Quality
The Anti Resonance Technology (A.R.T.) Wedge is a fifth foot in the centre of the unit. It dampens vibrations from the power transformer, power transistors and heat sinks, as well as vibrations that might be caused by the sound from the speakers.
Advanced Design Feet Enhance Strength and Vibration Resistance
The feet of the RX-A670 feature a newly designed, high-density structure which utilises two different kinds of interior ribs — straight and curved — to enhance strength and damping performance. Installation stability is improved and chassis resonance is dispersed, effectively eliminating external vibration. The low-range response is enhanced, while resonance peaks in the mid- and high-range are reduced, providing dynamic sound and focused, accurate reproduction.
Aluminium Front Panel Offers Visual and Aural Benefits
All of the AVENTAGE components feature the same sleek, clean design, with an elegant aluminium front panel and silky touch volume / selector knobs. The aluminium front panel is used to effectively shield sensitive circuitry from external noise and electronic radiation generated by dimmer switches, fluorescent lighting, video monitors and so on. This ensures optimum sonic performance in the widest range of installation environments.

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 for One-Touch Start

HD Audio with CINEMA DSP 3D and Virtual Presence Speaker
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.
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 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.
Zone B output provides 2-channel sound in a second room
Zone B output capability allows the receiver to send 2-channel sound to a second zone, so the main zone now has 5-channel output. This means that users can enjoy stereo sound in a second room. The same source will play in both zones (cannot use two sources).
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.
