Get Connected to the Cutting Edge of High-End Home Theater- The Onkyo TX-NR3009 sports a huge array of digital and analog connections, including eight 3D-ready HDMI® inputs, 9.2 multichannel pre-outs, and a USB input for connecting flash drives and digital audio players. An Ethernet jack, meanwhile, supports networked content in the form of internet radio and streaming audio from a PC or media server. Processing, too, is top-class. Audyssey MultEQ® XT32 achieves optimal balance for movie soundtracks and breathtaking realism for music sources. Along with sophisticated surround-sound technologies from Dolby and Audyssey, the TX-NR3009 employs DTS Neo:X™ to create an immersive nine-channel soundscape from any audio source. Video sources also get the red-carpet treatment, thanks to HQV® Vida™ processing, independent ISF calibration, and 4K upscaling via Qdeo™ technology. Onkyo's dedication to build quality is reflected in the low-resonance chassis, multiple transformers, three-stage inverted Darlington circuitry, and high-grade audio terminals. All this and more earns the TX-NR3009 coveted THX® Ultra2 Plus™ certification—your guarantee of an ovation-worthy performance every time.
