Onkyo TX-NR747 7.2-Ch Network A/V Receiver
THX-Certified Amp Quality
THX certification guarantees the same high volume, low distortion sound you experience in a commercial theater in your listening room. The TX-NR747 meets the most demanding & rigorous performance certification: it has to pass 75 test categories, 2,000 tests, covering 14,000 data points. THX Select2 Plus is recommended for screen-to-seat viewing distances of 10-12 feet.
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 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 enables transmission of High Dynamic Range (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
The TX-NR747 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:
A low negative feedback design for punchy, true-to-life sound, and cleaner audio across the frequency ranges.
Closed groundloop circuits to reduce individual circuit noise and keep the ground potential free of distortion.
A high instantaneous current to handle big dynamic gains.
This allows massive power at 175 W/Ch (6 Ohms, 1 kHz, 0.9% THD, 1 Channel Driven, FTC) and 110 W/Ch (8 Ohms, 20 Hz–20 kHz, 0.08% THD, 2 Channels Driven, FTC)
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-NR747 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.
