Yamaha RX-V477 5.1 Channel AV Receiver

This AV receiver provides advanced HDMI® features including pass-through of 4K Ultra HD, which is gaining popularity. 4K Ultra HD refers to four times the resolution of a 1080p display. This receiver is capable of passing the 4K Ultra HD data from the source to the monitor, for image clarity far beyond present standards.

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, 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.

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.

*As of spring 2014.

A USB port on the front panel allows convenient connection of an iPod / iPhone, which also charges when connected. Because the digital signal from the iPod / iPhone is transmitted directly to the AV receiver, there is no signal loss or interference, so you enjoy the best possible sound quality. In addition, you can use the receiver’s remote control unit to operate the iPod / iPhone music playback functions.

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.

Yamaha’s exclusive low-range enhancement technology delivers richer bass than you expect from the speaker size while maintaining good localization 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.

YPAO analyzes 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.

This AV receiver is equipped with a variety of sound programs that utilize Yamaha's original DSP technology. They allow you to easily create sound fields like actual movie theaters or concert halls in your room and enjoy natural stereoscopic sound fields. Now you can use the AV Controller App to adjust DSP parameters to your preference to match the type of music / movie or the mood you want to achieve. There are two modes, basic and advanced, that you can choose according to the type of adjustments you want to do.

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.

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.

The Total Purity Concept, which Yamaha has been cultivating for many years, encompasses high drive amp technology, high purity preamplification, anti-vibration technology and independent pure power supplies. All models have a fully discrete power amplifier that helps to minimize distortion. They also adopt independent pure power supplies, allowing dedicated power supplies for the analog and digital circuitry to prevent digital noise from affecting analog 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.

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 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.

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.

Yamaha’s new ECO mode reduces power consumption by about 20 percent. It can be set from the top of the GUI menu. 

* Compared to power consumption when ECO mode is off (Yamaha measurement).
