Yamaha RX-V471BL 3D 5.1 Channel Home Theater Receiver, Front Panel USB Connection, Dolby TrueHD and DTS-HD Master Audio, 105 Watts per Channel, Black

A versatile 5.1-channel AV Receiver with HD Audio decoding, 1080p HDMI with 3D and Audio Return Channel (4 In/ 1 Out) deliver crystal-clear, all-digital audio and video via a single cable, HDMI dramatically simplifies cabling and helps provide consumers with the highest-quality home theater experience. HDMI can provide an interface between most audio/video sources, such as a set-top box, Blu-ray player, DVD player, or A/V receiver and a video monitor, such as a High Definition Television (HDTV), over a single cable.

Audio Return Channel (ARC) is a distinctive 3D-ready function allows consumers to use a single HDMI connection to transfer digital audio from the TV back to the AV Receiver eliminating the need for a second cable between the TV and the home theater AV Receiver. 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.

The actually measured sound field data contain the information of the height of the sound images. CINEMA DSP 3D mode achieves the reproduction of the accurate height of the sound images so that it creates the accurate and intensive stereoscopic sound fields in a listening room. The Four SCENE buttons make operating the receiver easier than ever. They are initially set to default settings for BD/DVD Viewing, CD Disc Listening, TV Viewing and Radio Listening. Pressing a SCENE button will automatically launch a number of operations that initiate play of the source controlled by that button. Other SCENE settings are also available, such as iPod Listening, SiriusXM Listening [model dependent], TV Sports Viewing and Action Game Playing.

Browsing and selecting the settings is quickly accomplished by changing Input via the front panel and watching the on-screen display. The settings can be selected for one-time use, or they can replace the original default settings. The SCENE names can be changed also. Yamaha's YPAO system uses a small microphone and sophisticated equalization to automatically set the best sound for any room, no matter where the speakers are.

First it checks the speaker connections and phase of each speaker. Then it sends out tones which are captured by the microphone to analyze the room acoustics and sets a variety of parameters, such as the speaker size, the distance of the speakers and even the sound pressure level, etc. Until it achieves the best sound conditions for your room and you don't have to do anything!
