Dolby Pro Logic II is an improved technique used to decode vast numbers of existing Dolby Surround sources. This technology enables a discrete 5-channel playback with 2 front left and right channels, 1 center channel, and 2 surround left and right channels instead of only 1 surround channel for conventional Pro Logic technology. There are three modes available: “Music mode” for music sources, “Movie mode” for movie sources and “Game mode” for game sources.

Four SCENE buttons make operating the receiver easier than ever. They are initially set to default settings for DVD viewing, disc listening, TV viewing and radio listening. Pressing a SCENE button automatically launches a number of operations that initiate play of the source controlled by that button. Other SCENE settings are also available, such as iPod listening, XM listening, 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, too.

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!

HDMI (High-Definition Multimedia Interface) is the first and only industry-supported, uncompressed, all-digital audio/video interface. With the ability to 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 Disc™ player, DVD player or AV receiver and a video monitor, such as a high-definition television (HDTV), over a single cable.

Depending on the model of product, HDMI can support standard, enhanced or high-definition video, plus multi-channel digital audio on a single cable. It can support all currently-available compressed audio formats (such as Dolby® Digital and DTS) and most newer HDMI devices can support lossless digital audio formats like Dolby TrueHD and DTS-HD Master Audio™.

DivX is the video compression codec developed by DivX Networks and based on the MPEG-4 compression format. Its balance of high video quality and low bit rate has made it very popular and quickly established it as the best home video format thus far. The ability to play it on newer DVD models continues to add to its popularity as DivX Networks advances its support to many new household products. This compression technology has the potential for expanding the ways we view video media in much the way MP3 has given us many new ways to listen to music.

Short for MPEG-1 layer 3 audio, MP3 is a compression process used to shrink audio files by filtering out all noise that is not detectable to the human ear. MP3 is considered near CD-quality, but the file itself occupies approximately one tenth to one twelfth the space of the original CD format, making it the perfect medium for today’s smaller, memory based portable media players.
