An on-screen GUI (Graphical User Interface) display makes operating the receiver easy and intuitive. It is compatible with iPod, internet radio, PC and USB displays. Access and control everything you need from a simple and easy-to-navigate interface.
Improved Compressed Music Enhancer
Use the RX-V1800 as your portal to all your digital music
Yamaha's Compressed Music Enhancer is a popular feature that restores the sound of the original music from digitally compressed formats such as MP3. This receiver offers an upgraded version that processes multi-channel signals with a DSP algorithm, so all channels are enhanced, providing more accurate reproduction and more expansive sound. There are two modes: Straight Enhancer that enhances and outputs each input channel as-is, and 7ch Enhancer that downmixes the input channels to 2-channel and then outputs them as X-channel stereo (X being the number of input channels). Adaptive Dynamic Range Control
Adaptive DRC is a new volume control technology that is effective for low-volume listening, such as at night or with headphones. It applies DRC processing to eliminate the volume differences between loud commercials and ordinary programming and to take into account our ears' loss of sensitivity as volume decreases. The compensation is performed automatically, so all dialogue is heard clearly even at low levels, and there are no sudden loud bursts of sound. HD Audio Format Signals Capability
This receiver lets users enjoy the best possible and newest surround sound from Blu-ray Disc players and HD-DVD players. It supports the two lossy formats--Dolby Digital Plus and DTS HD High Resolution--as well as lossless formats such as Dolby TrueHD and DTS-HD Master Audio. YPAO Sound Optimization and Pure Direct for Highest Sound Quality
Yamaha's YPAO Sound Optimization system analyzes the acoustics of the room and adjusts various speaker parameters to provide optimum sound quality at the listening position--in less than three minutes! A new Quick Start function displays the YPAO Auto Setup menu when the microphone jack is inserted, so Start can be immediately selected. Six YPAO settings can be memorized.
Pure Direct is a special receiver mode that causes the signal to bypass all but the most basic audio circuitry, and even turns off the display to prevent any chance of noise interference. It provides the purest possible high-fidelity sound from all sources including USB and HDMI inputs.
Full HD 1080p Video Upscaling and Deep Color (30/36-bit) Transmission
The RX-V1800 does full HD 1080p upconversion from a variety of sources
The HDMI 1.3a interface upgrades the transmission of standard, enhanced, and high-definition video signals via HDMI for higher-than-ever quality through a single cable. With four HDMI input terminals, users and connect a variety of high-definition sources such as Blu-ray Disc or HD-DVD players and switch easily among them.
The receiver supports the latest HDMI 30- and 36-bit color depths, improved from the 24-bit depth of previous versions. This "Deep Color" allows the rendering of billions of colors for far greater accuracy. Colors are so vivid they seem to jump off the screen, with perfectly smooth tonal transitions and ultra-fine gradations between colors. It also enables many times more shades of gray, for higher contrast ratio. Auto Lip-Sync Compensation
When video and audio signals are transferred via HDMI and the video shown on a display and the audio output by an AV receiver, the video delay time (time from signal input until it is seen) and the audio delay time (time from signal input until it is heard) are different, so the video and audio slip out of sync. The Auto Lip-Sync compensation function monitors the video delay time, and automatically adjusts the amount of audio delay to eliminate the difference, so you hear the dialogue just as the person is speaking. Analog Video to HDMI Digital Video Upconversion
This is a function that converts analog signals from composite, S-Video or component terminals to output from higher quality HDMI digital video. This ensures the highest possible picture quality from the AV receiver to a monitor or TV via a single cable. It also performs down-conversion among component, S-Video and composite signals.
