7.2-Channel Network A/V Receiver
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, lowdistortion 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 highpower 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
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 highresolution 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 lineouts) let you power audio in another room equipped with
speakers. You can also assign surround back channels to biamp your front loudspeakers.
Fast Switching and Adjustment
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.
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.
4K Video Upscaling with Qdeo™ Technology
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.
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.
