Description
View larger THX Theater-Reference Sound Meets Ultra HD Entertainment Step up to THX-certified surround sound with the TX-NR737—the most potent and future-ready A/V receiver in its class. With a high- current massive transformer, discrete Three-Stage Inverted Darlington Circuitry amplification, and extremely robust construction, this heavyweight serves up floorshaking theater-reference sound. There are 4K/60 Hz-capable HDMI inputs for Ultra HD gaming and video at 60 fps, as well as support for HDCP 2.2. As most Hollywood movie studios are adopting HDCP 2.2 copy protection for future Full HD and 4K releases (including content streamed via the internet), this is a highly desirable feature. Also included is QdeoTM 4K upscaling technology so you can enjoy older DVDs and games in high resolution. Music lovers can choose from a selection of internet music services and stream almost any 192/24 hi-res, lossless, or compressed file format (including 5.6 MHz DSD) from compatible network- attached devices using built-in Wi-Fi and our free remote app. Bluetooth is also standard. Combining these features with class-leading sound quality and an easy-to-use GUI, the TX-NR737 delivers powerful studio-master entertainment at an affordable price. Customized Audio Parts WRAT (Wide Range Amplifier Technology) is based on high-current, low-impedance architecture. High instantaneous current realizes ultimate control of the speaker drivers for accurate and musical audio reproduction, from the most delicate piano passages the thunderous roar of an orchestra in full flight. High current better handles impedance fluctuations from the speakers (which can dramatically increase the load on the receiver), while ensuring there is always enough power to instantly respond to dynamic gains in movie soundtracks and music. High-Current, Low-Distortion Amplification for Supremely Good Sound To achieve best-in-class current delivery, the TX-NR737 is built around a custom high-output transformer, extra-large customized capacitors, and low impedance copper bus-plates. Three-Stage Inverted Darlington Circuitry amplifiers feature a discrete low-impedance output stage with high-current transistors for instantaneous power and extremely low distortion. And unlike some A/V receivers, the audio and video processors, DAC section, networking, pre-amp, amplifiers, and power supply are all separated to minimize electrical interference (noise) on audio signals. The culmination of over 60 years’ audio engineering experience, WRAT preserves the life and character of the master recording while guaranteeing an emotionally moving experience whether you’re listening to compressed digital music, a treasured LP, or a hi-res movie soundtrack.
Dolby Atmos Upgradeable Model
View larger Dolby Atmos Multidimensional Sound Onkyo is among the first to introduce the exciting Dolby Atmos surround-sound format to home theater environments. Dolby Atmos uses object-oriented mixing to layer independent audio elements through discrete channels, moving three-dimensional sound effects around the theater with astonishing realism. The format adapts to any home theater layout incorporating height channels for a more enveloping soundfield with extremely accurate directional and overhead effects. Ready for Next-Generation Ultra HD Entertainment HDMI for 4K Video at 60 fps Five of the receiver’s seven HDMI inputs are based on the latest HDMI specification to support 4K video at 50/60 frames per second and 21:9 aspect ratio for theater-reference movie display. Now you can add thunderous 7.2-channel surround-sound to blockbuster 4K 50/60 Hz games and movies for a breathtakingly realistic entertainment experience. The TX-NR737 also supports the latest HDCP 2.2 DRM copy protection standard via HDMI Input 3 and the main output. View larger Reference-Level Sound in Your Home THX certification guarantees the same high-volume, low-distortion sound of a commercial multiplex theater in your own listening space, with high-resolution studio-master soundtracks reproduced precisely as the director intended. Your TX-NR737 Network A/V Receiver has passed more than 2,000 laboratory bench tests across 75 categories and covering 14,000 individual data points to ensure that every aspect of audio performance meets rigorous THX standards for theater-reference sound. THX Select2 Plus is recommended for medium-sized rooms where the screen-to-seat viewing distance is about 3–4 m (10–12 ft. ). Universal Support for Wireless Audio Streaming Wi-Fi and Bluetooth Inside The TX-NR737 has Wi-Fi and Bluetooth technology built in. For network audio, use the remote app to stream music stored on your smartphone and to locate and stream hi-res audio from any network-attached DLNA-certified device (such as a PC or NAS). There are no hidden adapter costs, no need for close proximity to an Ethernet wall socket, and no long runs of unsightly cable just to enjoy a stable network connection. The receiver also has Bluetooth 2.1 + EDR on board. Pair up and stream whatever audio is playing on your compatible device, from MP3s to albums on YouTube. Audio streamed via Bluetooth is enhanced with Onkyo’s Advanced Music Optimizer, a DSP mode that restores compressed files to close to their original fidelity for beautifully full and natural sound. Making High-resolution Audio Easy for Everyone Onkyo A/V receivers are engineered for universal hi-res compatibility and ease of use. It’s now remarkably easy to enjoy albums mastered in high-resolution that you’ve downloaded and stored on your computer or media server. The remote app very quickly locates the 192/24 and 96/24 high-resolution audio files on your network-attached storage devices and sends them via DLNA to the receiver with zero loss in quality. Almost every hi-res and lossless format is supported, from gapless FLAC and WAV to ALAC and WMA. The TX-NR737 also handles 5.6 MHz DSD and Dolby TrueHD formats for the ultimate in depth and clarity. With surpassing DSP power, high-quality TI Burr-Brown D/A conversion, and Onkyo’s low-distortion amplification, hi-res music on your home theater is not only easy to enjoy, it sounds absolutely fantastic as well. AccuEQ Room Calibration To showcase the unique acoustical characteristics of your front loudspeakers, AccuEQ bypasses the front two channels so you can enjoy authentic hi-fi audio quality for stereo music, with no DSP correction applied. Instead, the included microphone measures the distances, crossovers, and output levels of the surround and center speakers from one easy listening position, which speeds up and simplifies the calibration process.

Customer Reviews
Good mid-range receiver with improved 4K supportJ. Pappan
The biggest selling point for this receiver is its support for 4K content. Many receivers will play 4k video, but not like this one. I upgraded to this receiver from the TX-NR609, which is an older THX Select2 Plus 7.2 receiver. I made the switch because I wanted a few of the new features, more power, and most importantly, improved 4K support. I decided to write this review for someone looking to upgrade from a low-range receiver - many readers in the market for this receiver may be bored (or even insulted) by such a high-level overview. I'll leave the low-level audiophile review to someone else with better savvy and prowess than myself.First of all - let's nail down the difference between 4K and Ultra HD (UHD). 4K is a cinematic standard equal to 4096×2160, which is twice the pixels of standard digital projection, 2048x1080. UHD is a consumer standard equal to 3840x2160, which is twice the pixels of Full HD, 1920x1080. As you'll see in many product descriptions, manufacturers will combine the terms, despite the fact they aren't synonymous. I'm not going to get into the weeds with the two terms, I'm going to stick with 4K, since the consumer market seems to be adopting the term over UHD.Here's a breakdown:4K support - This receiver supports HDMI 2.0 and HDCP 2.2, which is huge. In short, HDMI 2.0 allows 4K content to be displayed @ 60Hz, as opposed to 30Hz with HDMI 1.4. With the new standard being between 60-240Hz (with plasma displays typically operating at 600Hz!), 30Hz is not acceptable. Keep in mind, to achieve 60Hz you'll need a TV that features HDMI 2.0 support as well. HDCP 2.2 is important, as providers of 4K video will likely require this standard to view content in the future. HDCP is content protection, and if HDCP 2.Read more ›
Lots of features, thunderous sound, but a few disappointing corners have been cut.Alan Moore
The Onkyo TX-NR737 is a big home cinema receiver with a huge laundry list of features. It’s THX Certified, will fire up to a 7.2 surround system, and can power two other rooms. It has 7 HDMI sockets, can upscale analogue signals, receive from a DLNA server, and has wi-fi built in, even a phono port for a turntable. In terms of features, this is a good step up from a $200 - $500 receiver, and while it has a lot of power and ‘goes up to 11’, the quality of the sound when playing music is not significantly different from a lower-price receiver. You’re paying for the list of features, and there have been a few corners cut to get that list to be so long.THX Certified Surround, according to the brochure, will let you ‘Hear Movies Precisely As the Director Intended’. Apparently, ’every aspect of audio performance meets rigorous THX standards for theater-reference sound.’ I have no reason to doubt this, but I didn’t have any directors available to confirm their movies were being reproduced accurately. Treat this as marketing guff, because it will frankly depend on the quality of the media you’re playing, be that DVD, Blu-Ray or whatever.7 HDMI inputs is great news for homes with ever growing collections of devices. I fitted a Comcast cable box, and Blu-Ray player, an Xbox 360, a multi-region DVD player and an Apple TV. One caveat: The seventh HDMI is on the front panel. If you are going to have seven devices permanently connected, there will be one ugly cable visible at all times. Also, while the facility for handling 4k video is available, it’s actually not on every input: ‘Five of the receiver’s seven HDMI inputs are based on the latest HDMI specification to support 4K video at 50/60 frames per second and 21:9 aspect ratio for theater-reference movie display.Read more ›
love onkyoBarry J. Gervais
Great sound, I'm replacing a TX-NR 616 that I've had for a year and a half. I replaced because I want to be ready for atmos. I was a little concerned that audyssey is being replaced with Accu-EQ. But I read that onkyo and Dolby worked together to develop it. Set up was very easy and after room calibration sound is great, one thing I did use was a db meter to get to subs at 75db which helped a lot. The reason I used a meter, when you first set up with Accu-EQ you get a test tone for the sub but no indication what the db is, got them to 75 and proceeded with the rest of the set up very easy. One thing I did was place the hockey puck Mic on my tripod and placed it in my main listening position....The only issue I have is odd when the receiver is in stand by picture passes to the TV but no sound tried everything but can't get it to work with my TV I have directv genie > receiver > Samsung PN 51F 5500Which is odd is it works fine when I watch a blu-Ray through the receiver when it's in stand by. It must be some kind of handshake between directv genie and the receiver, I think it maybe that the genie is not cec don't know just a guess.This receiver has great sound and I can't wait till atmos...Update 8/17/14Not sure what I did but now when the receiver is on stand by my directv genie passes through video and audio.I would like to report that all is well when the TX-NR 737 sound and picture passes through when it's in stand by. The reason I like this feature is when I'm not home and someone who wants just to watch TV works perfectly..Read more ›
