The culmination of nearly 70 years’ audio engineering experience, our flagship model celebrates Onkyo’s proud heritage while pushing the boundaries of technology even further. Behind the thick anti-resonant exterior panels, you’ll find a massive toroidal transformer—assisted by separate transformers for audio and video processing—to power the Three-Stage Inverted Darlington Circuitry. Both are fundamental to achieving THX® Ultra2 Plus certification. Crucial details such as the premium 192 kHz/32-bit DACs, gold-plated speaker posts and terminals, and differential DAC mode will not escape the audiophile’s attention. Nor will the Audyssey MultEQ® XT32 and DTS Neo:X™ systems. Video processing is incomparably good, with technology from HQV®, Qdeo™, and ISF upscaling video sources to 4K. With HDMI® support for two displays, 11.4-channel pre-outs, and powered audio in three zones, your entertainment options extend throughout the home, yet are easily managed with our convenient remote apps and HDMI-enabled GUI. A total of 11 HDMI ports (including MHL™ for smart phone), DLNA, and ample legacy connections allow your media to be played with exhilarating power and accuracy. This iconic blend of phenomenal sound and advanced technology is why more home theater experts own an Onkyo.
