Virtual CINEMA FRONT Provides Virtual 7-channel Surround Sound with High Quality and Resolution
The Virtual CINEMA FRONT feature lets you place two surround speakers and a center speaker at the front to enjoy virtual 7-channel surround sound with even higher quality and resolution, as well as superior rear virtual sound localization. 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 would 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 - Reflected Sound Control Sound Optimization
YPAO R.S.C. analyzes room acoustics and measures various speaker characteristics, then calibrates audio parameters to achieve optimum sound. It employs Reflected Sound Control to correct early reflections for studio-quality sound. It also provides DSP Effect Normalization, which varies the CINEMA DSP parameters according to the reflected sounds.

YPAO Volume to Ensure Natural Sounds Even at Low Volume
Human ears have less sensitivity to high and low frequencies, especially at lower volumes. YPAO Volume applies loudness EQ correction to automatically adjust high and low frequency levels as volume changes. Using the YPAO measurement results, EQ correction is optimized to your system settings and listening environment.

HD Audio with CINEMA DSP 3D and Virtual Presence Speakers
CINEMA DSP 3D provides a wide, high and dense sound field. HD Audio format decoding lets you enjoy HD Audio sources. Virtual Presence Speakers deliver three-dimensional sound without actual use of presence speakers.

DSP Parameter Adjustment for Easy and Detailed Setting
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 to 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.

Gapless Playback Compatibility Allows Play without Interruption
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.

Compressed 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.

Intelligent Amp Assign
Intelligent Amp Assign automatically assigns amplifier channels to certain speakers, depending on what functions are selected. For example, in a 7.1-channel system, when Zone 2 is off, all 7.1 channels will be used in the Main Zone. However, when Zone 2 is on, power to the two surround back channels will be directed to the two speakers in Zone 2 and the Main Zone will receive 5.1 channels of power. Similarly, when CINEMA DSP 3D is on, the two Front Presence speakers will be powered and not the two surround back speakers. When CINEMA DSP 3D is off, this situation is reversed. Thanks to Intelligent Amp Assign, there's no need to switch the speaker cables on the rear of the receiver one more way Yamaha makes your life a little easier.

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 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 heat sinks 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.
