Product Description

Yamaha RX-A660 7.2-Ch Aventage AV receiver with MusicCast boasts the latest in audio visual tech with Dolby Atmos and DTS:X, 4K Ultra HD and built in WiFi and Bluetooth

Total Purity

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


The Anti-Resonance Technology Wedge is a fifth foot in the centre of the unit. It dampens vibrations from the power transformer, transistors and heat sinks as well as vibrations that might be caused by sound from speakers. 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 excellent audio performance.

Aluminum Front Panel

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.


MusicCast makes it easy to bring music to every room in your home wirelessly with playback controlled by a simple app. Start with a MusicCast AV receiver in your main entertainment room for the ultimate home theatre then add MusicCast speakers, sound bars or Hi-Fi components in other rooms wirelessly. MusicCast allows you to access your digital music library, streaming music services and Internet radio, as well as Bluetooth sources, your TV sound and external sources attached to your AV receiver, such as a Blu-ray or CD player.


Play your favorite streaming service. This AV receiver is equipped with Bluetooth functionality to let you enjoy easy wireless music playback from mobile devices. The Compressed Music Enhancer from Yamaha is now optimized for Bluetooth audio transmissions to ensure that your music will have vivid, lively sound quality during wireless playback. The RX-A660 is equipped with the latest Bluetooth technology, making wireless operation more convenient than ever. You can stream music from the RX-A660 to Bluetooth headphones for private listening or to Bluetooth speakers.

Wi-Fi & Wireless Direct

Built-in Wi-Fi allows for a wireless connection with your wireless router, greatly simplifying system connections for enjoying networked audio (PC / NAS) and music streaming services. If a Wi-Fi router is not available, the unique Wireless Direct feature not only allows you to stream music directly from your smartphone or tablet via the AV Controller App, AirPlay etc., but also allows for control of the AV receiver as well.

This AV receiver provides a variety of network functions that enable you to access more sources and also enhance operation. You can connect the receiver to your home network or internet to enjoy Internet Radio, Spotify, Pandora or music stored on a NAS and home PC. The AV Controller app (from iTunes App Store or Google play) lets you control various functions from your iPod, iPhone, iPad or Android phones / tablets.

Speaker Patterns

Multiple placement patterns are available for presence speakers that support Dolby Atmos & DTS:X, creating a sound field that’s ideal for your setup. Any layout can be appropriately reproduced, including the 3D space of CINEMA DSP and both sound formats. This AV receiver is compatible with many audio formats such as Dolby True HD and DTS-HD Master Audio. It is compatible with high-res audio codecs such as DSD/AIFF/FLAC/WAV or Apple Lossless. You will enjoy the excellent sound quality of these various high-resolution audio codecs from the USB input on the front panel or from network connected devices.

4K, HDR & BT.2020

This unit supports the latest HDMI standards thanks to transmission of 4K video at 60 frames per second (pass-through only). Fully enjoy HD video quality without degradation along with HDCP 2.2 that fully complies with the latest copyright protection, a standard for 4K video transmission. It also supports the wider colour gamut of BT.2020 pass-through.


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. 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, use the receiver’s remote unit to control player functions like Skip and Stop.

Compressed Music

When music is encoded into a digitally compressed format like MP3, the frequency response suffers. The Compressed Music Enhancer from Yamaha employs sophisticated digital signal processing using exclusive algorithms to restore what was lost, so the music always sounds the way it should. 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.

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. YPAO sound optimisation 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.

Virtual Presence

The Virtual Presence Speaker function makes full use of centre and surrounds to create virtual presence speakers. 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.

The Virtual Cinema Front feature lets you place two surround speakers and a centre speaker at the front to enjoy virtual 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.

Rich Bass

This exclusive low-range enhancement technology delivers richer bass than expected from smaller sized speakers while maintaining good localisation and sound balance even with compact front speakers. When a sub is used, volume of the entire low range is improved, 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

The Subwoofer Trim Control enhances the low frequencies by avoiding overlap with the front speaker output. This will result in a cleaner, more focused soundstage while providing a seamless frequency response. When subwoofer frequency overlap occurs in conventional systems, the overall sound is “pushed” toward the subwoofer. Subwoofer Trim Control takes care of this by separating the low subwoofer frequencies cleanly, thus stabilizing the front stage while providing a well-balanced enhanced bass sound.

AV Controller App

This AV receiver lets you use the Yamaha AV Controller App that is downloadable from iTunes, Google Play or the Amazon App store to control the power, volume, input selections, DSP modes and much, much more from an iPhone or Android device. You can also use as many as 23 different languages and customize the interface by hiding unused icons and renaming functions. A tablet version is also available.
