DTS:X Compatible

DTS:X is a next-generation object-based surround sound technology that includes height to deliver a fully-immersive listening experience. DTS:X provides listeners the ultimate in flexibility, immersion, and interactivity. Unlike channel-based audio, you will be able to personalize your audio experience. For example, you can turn up JUST the dialog within a mix. DTS:X allows you to customize to your room layout as well as control dialog and dynamic range.

Supports Dolby Atmos® Up to 5.1.2 Channels

With Dolby Atmos, sound comes alive from all directions, including overhead. The format combines a channel-based audio bed with object-oriented sound to place and move specific effects around the room, creating a breathtakingly realistic and captivating sonic atmosphere.

Sound designers and artists are free to mix in a 3D space, steering effects through surround channels and adding a seamless overhead dimension with discrete height channels.

Additionally, a new Dolby surround up-mixer allows for your current channel-based content (that has not been mixed for Dolby Atmos) to be expanded to fill the flexible speaker layouts of a Dolby Atmos system.

Ready for 4K UltraHD

The latest HDMI specification and HDCP 2.2 compatibility support the latest formats and technologies planned for Hollywood content. This latest HDMI spec offers a significant increase in bandwidth (up to 18Gbps) to support new features such as 4K@50/60 (2160p), which is 4 times the clarity of 1080p/60 video resolution, and 4:4:4 color space.

This Onkyo AVR is also compatible with HDMI 2.0a, which enables transmission of HDR formats, and provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image.

Bluetooth / Wi-Fi® with Pandora, Spotify, and AirPlay

This receiver has AirPlay, Wi-Fi and Bluetooth technologies built in. The free Onkyo Remote app puts a range of streaming options at your fingertips, from universal hi-res audio via network-attached devices to internet streaming services to music on your smartphone and tablet. Or pair up and enjoy whatever's playing on your Bluetooth-compatible device for huge cinematic sound.

This receiver comes loaded with Spotify, Pandora, SiriusXM Internet Radio, Slacker and TuneIn. You can select a station and search for music available on these services via the Onkyo Remote app on your phone. You'll never be short of your favorite music to enjoy.

Hi-Current Amp Design for Authentic Sound Reproduction

From the quietest dialog passages to booming action scenes, Onkyo's exclusive amplification technology dramatically enhances the audio dynamics of your movies, music and games.

This Wide Range Amplifier Technology (WRAT) is at the core of Onkyo's signature sound. The innovative amplifier design is comprised of three key elements:
(1) a low negative feedback design for punchy, true-to-life sound, and cleaner audio across the frequency ranges;
(2) closed groundloop circuits to reduce individual circuit noise and keep the ground potential free of distortion; and
(3) a high instantaneous current to handle big dynamic gains.

This allows massive power at 170 W/Ch (6 Ohms, 1 kHz, 0.9% THD, 1 Channel Driven, FTC) and 100 W/Ch (8 Ohms, 20 Hz–20 kHz, 0.08% THD, 2 Channels Driven, FTC).

Classic Analog & Hi-Res Digital

This receiver is engineered for hi-res analog and digital audio. You can spin your classic vinyl and hear it in all its analog glory and stream your networked hi-res digital files. Both analog and digital audio sound its warmest and clearest. This AVR supports hi-res audio playback, gapless playback, and the ability to play DSD, Double DSD, FLAC and ALAC along with other Hi-Res formats.

Powered Zone 2 and Zone 2 Line-Outs

This receiver features Powered Zone 2 and Zone 2 line-outs. This lets you assign two channels to power audio in a room equipped with speakers. An existing hi-fi system in a third room can also be connected via the line-out, enabling the use of the A/V receiver as a pre-amp and audio server. Control content in the two zones via remote app; play the same song in all zones using Whole House Mode; or enjoy a different song in each room.
