Specifications and features

“We recommend purchasing Onkyo products only after experiencing an in-store demonstration where the advantages and features of Onkyo products will be explained to you.”

This Onkyo network receiver is the big winner in three areas. First, its video performance is unmatched. An HQV VidaTM VHD1900 processor converts content up to 1080p, and QdeoTM technology ensures stunning 4K upscaling from Full HD.

An ISF system adapts video from all inputs to industry standards to produce a spectacular picture. Next, its audio performance is unprecedented, as evidenced by THX Select2 PlusTM certification.

This receiver delivers maximum power effortlessly thanks to three-stage inverted Darlington circuitry and 192 kHz/24-bit analog-to-digital converters. Finally, its installation flexibility is extraordinary.

It features eight inputs (including an MHL input for smartphones) and two HDMI outputs.

Two USB ports allow you to connect an iPod/iPhone and a wireless network adapter to play files stored on your computer and listen to online music, all wirelessly.

It incorporates three exceptional sound expansion systems (Audyssey DSX, DTS Neo:XTM, and Dolby Pro Logic IIz), assisted by Audyssey MultEQ XT32 room acoustic correction.

Digital crossover processing, front bi-amping, and three-zone audio distribution allow for unlimited customization. Additionally, it features the new InstaPrevueTM input selection technology and enables intuitive system control via iPhone or Android phone. Onkyo quality: don’t wait any longer.
