This Onkyo network receiver is a winner in three areas. Firstly, 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. Secondly, its video performance is unrivalled. An HQV Vida VHD1900 processor upscales 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. 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. And, with the new InstaPrevue technology and intuitive system control apps, now is the time to upgrade to an Onkyo.
