7.2-Channel Network A/V Receiver

High-End Home Theater Performance Starts Here

This Onkyo network receiver is a winner in three areas. Firstly, its video performance is unrivalled. A dual core video engine design utilizes an HQV® Vida™ VHD1900 processor to upscale analog content to 1080p, with Qdeo™ technology taking full HD out to an eye-popping 4K. An ISF system calibrates video from all inputs to industry standards, and the resulting picture is spectacular. Secondly, audio performance is unmatched, as proven by THX® Select2 Plus™ certification. The receiver delivers power effortlessly through three-stage inverted Darlington circuitry and 192 kHz/24-bit DACs. Finally, you get more setup flexibility. There are eight HDMI® inputs—including an MHL for smart phones—and two outputs. Two USB ports connect iPod/iPhone and LAN adaptor, enabling wireless PC and online audio. Three mind-blowing sound expansion systems are included—Audyssey DSX®, DTS Neo:X™, and Dolby® Pro Logic® IIz—assisted by Audyssey MultEQ® XT32 room correction. Digital Processing Crossover Network, front channel bi-amping capability, and three-zone audio distribution grant the freedom to customize. With new InstaPrevue™ input selection technology and intuitive system control via iPhone and Android phone, now is the time to upgrade to an Onkyo.

World’s Best Video Processing

Three of the best video processing and enhancement systems are included to guarantee smooth and accurate images on your HDTV.

HQV® Vida™ VHD1900
The Vida VHD1900 upscales analog content to 1080p, and enhances native high-definition sources. The chip employs multi-cadence tracking, expanded 12-bit color processing, and four-field motion-adaptive de-interlacing. Auto HQV™ enhances the incoming image, while HQV StreamClean™ cleans up video from lower-quality online sources by eliminating mosquito and block noise.

Marvell Qdeo™ Technology
Qdeo technology upscales 1080p sources to 4K (4096 x 2160)—even content already upscaled from lower resolutions by the HQV Vida processor. Played back on a compatible 4K display, your high-definition content will look more cinematic than ever.

Marvell Qdeo™ Technology
Qdeo technology upscales 1080p sources to 4K (4096 x 2160)—even content already upscaled from lower resolutions by the HQV Vida processor. Played back on a compatible 4K display, your high-definition content will look more cinematic than ever.

ISF Video Calibration
ISF (Imaging Science Foundation) video calibration dramatically improves picture quality. Each video input source is independently calibrated to achieve the best possible performance from your connected HDTV.

Note: 4K video playback requires a 4K-compatible TV. HDMI pass-through of 4K content from source devices is not supported. 4K upscaling of analog video is only available at 480i.

Three High Performance Sound Expansion Systems

A seven-channel system provides a more immersive entertainment experience, with additional High or Wide channels convincing you with realistic directional and ambient effects. Audyssey DSX®, Dolby® Pro Logic® IIz, and DTS Neo:X™ expansion systems offer you freedom to choose your preferred speaker setup. Audyssey DSX can expand 5.1 sources to incorporate Wide or Height channels. The Dolby system adds Height channels and stereo source expansion, while DTS Neo:X offers Wides or Heights with cinema, music, or game listening modes.

Audyssey MultEQ® XT32

Audyssey’s top-of-the-line room correction suite equalizes the sound to suit the unique acoustics of your listening space. High-resolution filters are applied to all channels—including subwoofers—based on information collected from more than 10,000 individual control points across eight measurement positions.
