TX-NR905 7.1-Channel Home Network Receiver

Making Waves as the Best in High-Definition, Networked Home Entertainment

Meet the standout leader of Onkyo’s new range of home theater heroes. Embracing all of the technologies synonymous with the 2007 line-up—including HDMI 1.3a, Dolby® TrueHD, DTS-HD® Master Audio,THX™ Ultra2™ and Audyssey MultEQ® XT—the TX-NR905 7.1-channel home network receiver has a number of advantages that propel it into the home theater super league. Look to the TX-NR905's network (interfacing with Windows Media Player and Windows Media Connect) to open up a huge reservoir of internet and computer-based audio resources. And enjoy the edge in high-definition 1080p video processing from the world’s first receiver to incorporate HQV Reon VX. In line with Onkyo’s impeccable track record, under the hood of the TX-NR905 you’ll find an innovative power supply, remarkable amplification design, and high-performance parts from the likes of Texas Instruments. “Complete” is a tag not given lightly, but the TX-NR905 earns it in style.

HQV Reon-VX Chip for High-Performance Video Processing (with 1080p Upscaling)

The TX-NR905 is the world’s first A/V receiver to incorporate HQV Reon-VX video processing. HQV Reon-VX will scale all video signals to 1080p without the visible inconsistencies found in less competent scalers. It also provides the ultimate support for standard and high-definition deinterlacing; for filtering of jaggies and artifacts; and for the reduction of random, “mosquito” and block (codec) noise. HQV Reon-VX enables color region enhancement and the rendering of more than one billion colors.

THX Ultra2 Certification for a Better Class of Home Theater

Ultra 2 certification means that the TX-NR905 can easily handle the requirements of a home theater where the viewing distance from screen to seat is greater than 12 feet and the room volume is greater than 3000 cubic feet. Among its technologies, Advanced Speaker Array (ASA) digitally reconfigures surround speakers for three listening modes: movies, music and gaming. You also benefit from Boundary Gain Compensation (BGC), which realizes a truer, more accurate bass response. THX Ultra2 certification is a powerful endorsement of the receiver’s amplifying abilities.

Network* for Streaming Audio Files and Internet Radio

The TX-NR905's network gives you access to digital music files (AAC, WMA, MP3, WAV) via an Ethernet network between the TX-NR905 and your computer. It also enables you to access music files from a USB mass storage device or a portable audio player through the USB port on the TX-NR905’s front panel. At the heart of the network is Windows Media Connect or Windows Media Player (the TX-NR905 is Microsoft PlaysForSure certified), which enable the TX-NR905 to play DRM music downloads from Napster and CDquality files from MusicGiants. For internet radio, you can access stations that use MP3 or WMA streaming. You can enter URLs (including those for podcasts) directly into your computer’s web browser, or you can enter them with your remote control. The TX-NR905’s user-friendly interface lets you easily access and store your favorite channels.
*This network also enables installation configuration and set-up of Crestron and AMX controllers with your home theater system or network.

Processing 1080p Video and High-Resolution Audio via High-Definition Multimedia Interface (HDMI 1.3a)

With four HDMI inputs, you can receive and switch the latest high-definition components—Blu-ray Disc and HD DVD players, satellite and cable boxes, media centers, and gaming consoles—for a simple, one-cable digital connection to an HDTV through either of the two assignable HDMI outputs (Main and Sub). HDMI delivers the latest high-definition audio formats—Dolby TrueHD, DTS-HD Master Audio, Dolby® Digital Plus and DTS-HD® High Resolution Audio—which are processed by the TX-NR905’s onboard decoders. These new formats enable unprecedented quality, including bit-for-bit reproduction (in TrueHD and Master Audio). Also, HDMI 1.3a gives you greater bandwidth to deal with higher resolutions, 36-bit Deep Color™ and high frame rates.
