Dolby Atmos® Multidimensional Sound
Onkyo is among the first to introduce Dolby Atmos sound to home cinemas. Dolby Atmos uses object-oriented mixing techniques to layer independent audio elements through discrete channels, placing and moving sound effects above and around the listener with astonishing realism. The format adapts to any home cinema layout augmented by two or more in-ceiling height speakers or Dolby Atmos-enabled front speakers to bring sound alive from all directions.

THX® Select2™ Plus for Reference-Level Sound
THX certification guarantees the same high volume, low-distortion sound you experience in a commercial cinema in your listening room. Your TX-NR737 receiver passed more than 2,000 laboratory tests covering 14,000 data points to ensure every aspect of audio performance meets rigorous THX standards for cinema-reference sound. THX Select2 Plus is recommended for screen-to-seat viewing distances of three to four meters.

Engineered for High Fidelity
WRAT (Wide Range Amplifier Technology) is all about high current. You need it to stay in control when speaker impedance fluctuates, and to grip without clipping as the soundtrack explodes into action. We use a massive high-power transformer driving low-distortion Three-Stage Inverted Darlington Circuitry on all channels to create a dynamic and engaging sound. Combined with high-resolution processing, the TX-NR737 packs a punch for movies while retaining finesse and musicality for two-channel playback.

Future-Ready with the Latest HDMI®
Play the latest RPG blockbuster on your Ultra HDTV at a breathtaking 60 frames per second with 7.2-channel surround sound from Onkyo. With five of the seven HDMI inputs supporting 4K/60 Hz, this dream can become reality with the TX-NR737. Even if you’re not planning on upgrading to a 4K display right away, it’s good to know your receiver is ready for it.

Supports HDCP 2.2 for 4K Streaming and TV
With Hollywood studios, satellite TV broadcasters, and video streaming services moving to HDCP 2.2 copy protection for future 4K and Full HD releases, it’s important your A/V receiver can handle this new standard. The TX-NR737 is one of the first A/V receivers to support HDCP 2.2, making it ready for the next generation of home entertainment.

4K Video Upscaling with Qdeo™ Technology
The TX-NR737 features Qdeo™ technology from Marvell to upscale low-res video to liquid-smooth 1080p (for HDTV) and 4K (3840 x 2160 pixels) with a compatible display. This means video from older gaming consoles and DVD players looks sharp and clean, giving old favorites a new lease on life.

Wi-Fi® and Bluetooth Inside
The TX-NR737 has Wi-Fi and Bluetooth technology built in. Download our free control app and you’ve got a graphic remote control and range of streaming options in the palm of your hand. Or pair your Bluetooth-capable device and send almost any audio to your home cinema. With Advanced Music Optimizer enhancement, music via Bluetooth never sounded this good.

Stream Direct from Smartphone and Tablet
For lossless audio streaming, tap on the Onkyo Remote App icon on your smartphone to find your music loaded and ready to stream with familiar song organization and playback controls. The receiver can switch on and select your preferred listening mode automatically.

Stream Network-Attached Hi-res Audio
Onkyo A/V receivers are engineered for universal hi-res compatibility and ease of use. Use the remote app to locate your 192/24 and 96/24 albums (including 5.6 MHz DSD) on PC or NAS and bask in the clarity, depth, and detail of high-resolution music.

Built-in Internet Radio and Streaming
If you can think of it, you’ll most likely be able to stream it. The receiver includes Spotify, AUPEO!, TuneIn, and now Deezer, the music subscription service available in over 200 countries and boasting a library of 30 million songs which you can browse using the remote app.

Play Lossless Music from USB
The front-panel USB port also plays almost any audio format from mass-storage-class drives. As well as compressed files, there’s support for FLAC, WAV, ALAC, Dolby® TrueHD
(48 kHz), and DSD.

Connect with MHL™
An HDMI/MHL terminal is included to connect smartphones and other electronic devices, allowing you to display 1080p video and other media on your HDTV with 7.1 channels of surround sound.

Powered Multi-Zone Audio and Bi-Amping
Powered Zone 2 speaker terminals (and Zone 2/3 line-outs) let you power audio in another room equipped with speakers. You can also assign surround back channels to bi-amp your front loudspeakers.

Fast Switching and Adjustment
To quickly adjust a speaker level or switch DSP modes, use the “Q” button on the remote control to overlay a transparent menu on screen. InstaPrevue™ technology is available via the Home button to preview content on any HDMI-connected device.

AccuEQ Room Calibration
AccuEQ optimizes surround-sound and two-channel audio to suit your listening space. In particular, AccuEQ extracts the best possible performance from your front speakers to make stereo listening more dynamic and exciting. The system analyzes speaker setup and room acoustics from one listening position (which simplifies the calibration process) and optimizes frequency response and output levels for maximum clarity.
