Onkyo TX-NR646 7.2-Channel Receiver Features:

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.

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).

HDMI 8 In / 2 Out Including 1 Front (4K UltraHD / HDCP 2.2)

  • All HDMI terminals support 4K/60Hz, as well as HDCP 2.2 for next-generation UltraHD streaming and broadcasting.

Bluetooth Audio / Wi-Fi with Spotify and AirPlay

  • The TX-NR646 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.

384 kHz/32-bit Hi-Grade DAC

  • No matter what you're listening to, it will sound powerfully full, clean and clear. A premium-quality AK4458 digital-to-analog converter from Asahi Kasei implements unique low-distortion filtering technologies for clear sound, and unlocks the full potential of any audio format, including compressed, lossless, and hi-res audio (MP3, WMA, WMA Lossless, FLAC, WAV, OggVorbis, AAC, Apple Lossless, DSD 5.6 MHz, LPCM, and Dolby TrueHD).

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. The TX-NR646 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

  • The TX-NR646 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.
