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.

Onkyo Sound is Emotion, Delivered
Drivers don’t judge sports cars on top speed alone. Acceleration, cornering, and braking are equally important. It’s the same with A/V receivers—wattage is an indication of loudness, not sound quality. The real test is current. High instantaneous current enhances speaker control for accurate and musical audio reproduction, from delicate piano passages to the full-throated roar of an orchestra. It’s the cornerstone of our amplification philosophy, and no one can match Onkyo for dynamic driving power. We don’t just translate signals into sound. We create sound you can feel.

Engineered for Pure Exhilaration
High current is achieved with Wide Range Amplifier Technology (WRAT). The design is built around a custom high-output transformer, customized 15,000 μF capacitors, and low-impedance copper bus-plates. Three-Stage Inverted Darlington Circuitry amplification features a discrete low-impedance output stage with high-current transistors for instantaneous power and extremely low distortion. The culmination of over 60 years’ audio engineering know-how, WRAT preserves the life and character of the master recording.

THX® Select2™ Plus for Reference-Level Sound
THX certification guarantees the same high volume, low-distortion sound you experience in a multiplex cinema. Your TX-NR838 receiver passed more than 2,000 laboratory tests to ensure every aspect of audio performance meets THX standards for cinema-reference sound. THX Select2 Plus is recommended for screen-to-seat viewing distances of three to four meters.

Pure Direct Analog Path for Interference-Free Hi-fi Amplification
Pure Direct Analog Path mode brings higher fidelity to vinyl, SACD, or CD playback via your home cinema. With this mode engaged, every digital circuit is physically shut down to prevent interference. Signals pass directly from the phono or analog audio inputs to the amplifiers and arrive at your front loudspeakers in pure analog form. The improvement in audio quality is quite dramatic, with the rich tonal character of your LPs shining through. This mode lets your A/V receiver double a dedicated all-analog hi-fi stereo amplifier.

Latest HDMI® for 4K/60 Hz Video and HDCP 2.2
All HDMI terminals (except Input 5/6) feature the latest HDMI supporting 4K video at 60 frames per second and 21:9 cinema aspect. Now you can add enveloping surround-sound to next-generation Ultra HD games and video for truly breathtaking entertainment. The TX-NR838 also supports HDCP 2.2 copy protection, which is essential for viewing future premium streamed and broadcast Ultra HD and Full HD content.

4K Video Upscaling with Qdeo™ Technology
The TX-NR838 features Qdeo™ video processing technology to upscale low-resolution video to liquid-smooth 1080p (for HDTV) and 4K for compatible displays. This means video from older games and DVDs looks sharp and clean, giving your old favorites a new lease on life.

Share Your HD Video Sources in Two Zones
Use the HDMI Sub Out to connect a second display in another room. This allows you to route 1080p content from the media players connected to your receiver and play it back on another TV with easy smartphone control.

Wi-Fi® and Bluetooth Inside
Wi-Fi and Bluetooth technology are built in. Download our free app and you’ve got a graphic remote control with a 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 so good.

Stream Music 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 with familiar song organization and playback controls. You can also browse and stream millions of tracks on Spotify and Deezer (as well as a variety of internet radio services) from within the app.

Stream Network-Attached Hi-res Music via Remote App
You can also use the app to locate and stream your 192/24 and 96/24 hi-res albums (including 5.6 MHz DSD) via DLNA. Bask in the extraordinary clarity, depth, and detail of high-resolution music.

Powered Multi-Zone Audio and Bi-Amping
Powered Zone 2 speaker terminals let you power audio in another room equipped with speakers, controlling content in both zones via smartphone. You can also assign surround back channels to bi-amp your front loudspeakers.

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.
