[Video Features] 4K pass-through for next generation super high resolution images

This AV receiver provides advanced HDMI features including 4K pass-through. 4K refers to a super-high resolution video format (approximately four times the resolution of a 1080p display). While not yet available, 4K displays and sources are sure to become popular in the future. This receiver is capable of passing the 4K data from the source to the display, for image clarity far beyond today's standards.

HDMI with 3D and Audio Return Channel

This 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.

Other notable video features

  • Supports Deep Colour (30/36 bit), x.v.Colour, 24 Hz Refresh Rate and Auto Lip-Sync compensation

[Advanced Features] YPAO automatic speaker setup for optimal sound

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.

SCENE for One-Touch Start

Pressing a SCENE button powers on the AV receiver and selects the input source and DSP mode. You can reset 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.

Input selection in HDMI Standby Through mode

When the AV receiver is in HDMI Standby Through mode, the input source (Blu-ray player, game console, etc.) for viewing on the monitor can be changed via the remote control. There’s no need to turn on the AV receiver in order to switch sources.

Other notable advanced features

  • Charging of iPod, iPhone and iPad via USB when AV Receiver is off
  • iPod/iPhone song titles displayed in English and Western European languages on the front panel
  • Multi language colour OSD for improved visibility (English, German, French, Spanish, Russian and Chinese)
  • Audio input assign capability for HDMI and component video input
  • Audio Delay for adjusting Lip-Sync (0-250 ms)
  • 40-station preset tuning / Auto preset tuning
  • Preset remote unit
  • Background Video feature (for Radio only)

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.

Compress 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.

Adaptive DRC (Dynamic Range Control)

Adaptive DRC automatically adjusts the dynamic range of the sound according to the volume level. This ensures that you hear clear dialogue and vocals, and all sound effects at comfortable levels. There is no need to adjust the volume level as you listen; everything from whispers to big explosions will be heard clearly and comfortably at the same volume setting. It also tones down loud TV commercials, and is ideal for low-volume, late-night listening, when you do not want to disturb others.

Other notable surround realism


[Eco-Friendly Design] 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 Down

Auto Power Down lets you save energy by selecting to turn off the power after 2, 4, 8 or 12 hours.

Low standby power consumption

Yamaha makes its receivers eco-friendly with a low standby power consumption of 0.1W in IR Standby mode (1W in HDMI Standby Through mode, 2W in Network Standby mode).

2-Way, 3-Speaker System

The large cabinet houses a 2-way, 3-speaker design consisting of Two 16cm (6-1/2”) cone woofer and a 3cm (1”) soft dome tweeters. Made with high quality materials, these speakers deliver strong bass and rich, natural sound with none of the harshness that causes listener fatigue.

Excellent Reproduction of HD Sources

The front speakers are designed to provide outstanding reproduction of HD movie and music sources. Using them together with the centre and surround speakers ensures that you will enjoy accurate, well-balanced sound, for an affordable yet high quality home theater system.

Large-size, gold-plated screw terminals

The extra-large, screw-type terminals are gold-plated to ensure maximum signal transmission efficiency. They are capable of handling HD audio signals with no loss of sound quality.

Luxurious Presence

In the tradition of fine quality Yamaha speakers, the floorstanding front speakers have a graceful and elegant appearance. If desired, the speaker grilles can be removed.
