Unparalleled Processing Power for High-Resolution Audio
Most conventional A/V receivers use just one Digital Signal Processor (DSP) to decode digital audio. The Onkyo TX-NR737 doubles the powerwith two 32-bit processing engines handling multichannel studio-master soundtracks along with a large variety of hi-res audio files, including 5.6 MHz DSD (the same format used for Super Audio CD). The dual DSP engines are super-efficient at decoding these complex files so you can enjoy effortlessly smooth high-resolution playback.
Customized Audio Parts for Supreme Sound, Part 1
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 respond instantly to dynamic gains in movie soundtracks and music.
Customized Audio Parts, Part 2
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. The audio and video processors, DAC section, networking, pre-amp, amplifiers, and power supply are allseparated 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 whether you're listening to compressed digital music, a treasured LP, or a hi-res movie soundtrack.
AccuEQ Room Calibration
Effective Correction for Dynamic Multichannel and Stereo Sound
Onkyo developed AccuEQ to simplify the initial home theater setup process, and to make both surround-sound and two-channel audio sound clean and clear in your listening space.
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. With room correction complete, you can enjoy perfect clarity and three-dimensional cohesion when playing multichannel movie soundtracks, and natural high-fidelity performance for stereo listening.
Engineered to Make Hi-res 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.

Multi-Zone Audio and Front Channel Bi-Amping Capability
Dedicated Zone 2 speaker terminals can power audio in another room equipped with a pair of stereo speakers, while line-level outputs for Zone 2/3 allow you to send audio to a power amp and speakers in a third zone. Use your smartphone or tablet to play music simultaneously in every zone with the convenient one-touch Whole House Mode, or play a different source in each room.
You can also assign the Surround Back channels to bi-amp your compatible front loudspeakers, while two parallel subwoofer outputs enable the connection of a second subwoofer for balanced and powerful bass sound.
