<b>7.2-Channel Network A/V Receiver w/ HDMI 2.0</b>
Spellbinding Entertainment, However You Like It
Destined to intoxicate hi-fi enthusiasts as much as film lovers, the TX-NR838 boasts the absolute latest in high-resolution A/V processing. This heavyweight marries Onkyo’s Emotion, Delivered high-current amplification with Dolby Atmos multidimensional sound, a format that locates and moves directional audio above and around the listener in a seamless sphere of living sound. Thanks to the massive customized transformer and discrete Three-Stage Inverted Darlington Circuitry, you can feel the awesome power of multiplex movies in your own home. Hi-fi credentials are further cemented with Pure Direct Analog Path, a selectable mode that shuts down all digital circuitry when you’re listening to LPs or other analog audio sources for pristine sound. Devotees of high-resolution can stream their network-attached hi-res albums using the remote app and Wi-Fi, or get an instant fix with a smartphone and DSP-enhanced Bluetooth. The TX-NR838 is also packed with cutting-edge features for movies and gaming, with 4K/60 Hz-ready HDMI terminals, HDCP 2.2 for future Ultra HD video streaming, and the sheer power you need for a convincing surround-sound experience.
<b>Onkyo Sound is Emotion, Delivered</b>
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.
<b>Engineered for Pure Exhilaration</b>
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.
<b>THX Select2 Plus for Reference-Level Sound</b>
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.
<b>Pure Direct Analog Path for Interference-Free Hi-fi Amplification</b>
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.
<b>Future-Ready with the Latest HDMI</b>
Imagine playing the latest blockbuster games on your Ultra HDTV at a breathtaking 60 frames per second with 7.2-channel Onkyo surround sound. With HDMI 2.0 terminals supporting 4K/60 Hz, this dream is now reality. Even if you’re not immediately upgrading to a 4K display, it’s great to know your receiver is ready when you are.
<b>Supports HDCP 2.2 for 4K Streaming and TV</b>
With Hollywood studios, satellite TV broadcasters, and video streaming services moving to HDCP 2.2 for future premium releases, it’s important that your A/V receiver can handle this new copy protection standard. The TX-NR838 is HDCP 2.2-compliant to handle the next generation of home entertainment.
<b>4K Video Upscaling with Qdeo Technology</b>
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.
<b>Share Your HD Video Sources in Two Zones</b>
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.
<b>Wi-Fi and Bluetooth Inside</b>
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.
<b>Stream Music from Smartphone and Tablet</b>
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.
<b>Stream Network-Attached Hi-res Music via Remote App</b>
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.
<b>Dolby Pro Logic IIz Seven-Channel Upmixing</b>
Dolby Pro Logic IIz adds a vertical dimension to the soundstage with two front height channels. The system upmixes stereo or 5.1 sources and offers optimized listening modes for different types of content.
<b>Powered Multi-Zone Audio and Bi-Amping</b>
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.
<b>AccuEQ Room Calibration</b>
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.
