Dolby Atmos® Multidimensional Sound
Onkyo is among the first to introduce Dolby Atmos sound to home theaters. Dolby Atmos uses object-based 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 theater 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 theater 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 theater-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 HDMI® 2.0
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.
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 theater. With Advanced Music Optimizer enhancement, music via Bluetooth never sounded this good.
AccuEQ Calibration for Pure Audio Performance
As part of our Emotion, Delivered audio concept, which brings together technologies that significantly improve both stereo and multichannel sound quality, Onkyo introduces the powerful AccuEQ room calibration system. AccuEQ measures and corrects speaker distances, levels, crossovers, and frequency response from one convenient listening position to ensure clear and cohesive surround-sound while enabling playback of 7.1-channel formats at 96 kHz (no down-sampling). For the ultimate in pure stereo performance, AccuEQ bypasses the front channels so the unique characteristics of your loudspeakers can be enjoyed without DSP correction to potentially alter the sound.
