About the Onkyo TX-NR838
Heighten your senses with the latest surround sound development
Heighten your senses with the latest surround sound development
Surround back speakers are so last year. Add height to your home theater's sound stage with the Onkyo TX-NR838. When you upgrade this receiver's firmware for Dolby Atmos® capability, you'll be ready to experience a new dimension in home theater immersion as sound is projected from above your listening positions. Dolby Atmos lets you swap out surround back channels for in-ceiling speakers or special Dolby enabled speakers that reflect sound off the ceiling. It's just the latest technology the TX-NR838 can add to your home theater. There's also 4K video processing, Wi-Fi and Bluetooth for wireless music, and THX® certification for intense movie realism with traditional surround sound setups.
Dolby Atmos adds a new dimension to sound
Dolby's latest surround sound technology was designed to bring a new level of immersion to your home theater. By employing in-ceiling speakers or special Atmos enabled upward-firing speakers that reflect sound off your ceiling, Dolby Atmos offers a greater sense of space for sound that's more three-dimensional. Already at work in film production studios and many movie theaters, Dolby Atmos represents a huge step in putting more "theater" into your home theater.
The TX-NR838 lets you add two overhead or up-firing speakers (sometimes called "height" or "top" speakers) to a conventional five-channel system — this is referred to as a 5.1.2 Dolby Atmos setup. You can use either one or two subwoofers with this setup.
Wi-Fi and Bluetooth offer lots of music choices
Music is increasingly delivered from sources other than shiny discs. Smartphones, tablets, computers, Internet radio, and subscription services offer a wealth of listening options. You can take advantage of all of them with the TX-NR838. Stream music from smartphones and tablets over Bluetooth, to play audio from any app through your home theater speakers. If you have a digital music library stored on a networked PC or storage drive, Wi-Fi lets you play those tunes over your home network. There's also built-in support for Spotify®, Pandora® Internet radio, SiriusXM, and free Internet radio streams via TuneIn radio. With so many choices, you'll never have trouble finding something to listen to. Plus, Onkyo's Music Optimizer helps flesh out the sound of compressed files and Bluetooth streams.
Listen to music from online music services using Onkyo's free remote app for Apple and Android smartphones.
Emphasis on sound
The 'NR838 is about more than just convenience and versatility. Onkyo has always put a premium on sound quality. This receiver features their Wide Range Amplifier Technology, which provides plenty of current to ensure smooth sound even during large swings in dynamics. This reduces distortion while ensuring music and movie soundtracks have plenty of punch. Phase-Matching Bass Enhancement keeps low-frequency tones from muddying the midrange, so you get plenty of deep bass while vocals and dialogue remain clear and detailed. If you've downloaded high-resolution music from sites like HDtracks, you'll appreciate this receiver's ability to decode high-res files like FLAC, WAV, Apple Lossless, and DSD. Or kick it old school by connecting your turntable and enabling Pure Direct Analog Path to turn off all digital circuitry for top-shelf analog playback.
Multi-room audio and video
If you'd like to add speakers to an adjoining bedroom, kitchen, or porch, you can plan ahead with the TX-NR838. Powered Zone 2 outputs let you use two of the receiver's amplifier channels to drive an additional set of speakers for use in another room. Two HDMI outputs operate independently, so you can even watch different video content on a second TV. While the kids enjoy a movie on Blu-ray in the home theater, you can catch the ballgame on cable in the bedroom. When feeding a second TV via Zone 2 HDMI, you can use the TV's speakers — or for better sound, consider hooking up your old receiver to some additional speakers in that second room. The 'NR838 also has line-level Zone 3 outputs for even more multi-room flexibility.
Simple setup and control
The tiny microphone that's included with the TX-NR838 is your key to properly calibrated home theater sound. Plug it into the front of the receiver, and let Onkyo's AccuEQ optimize your system for your room and speaker setup. This ensures you'll get the best possible sound in your room, even if its odd layout forces you to place speakers in less than ideal locations. Before you start exploring this receiver's features, be sure to download the Onkyo remote app to your Apple® or Android™ smartphone. It offers easy control of the receiver's most important functions, as well as giving you instant access to Internet radio and other online music choices.

Audio Features
7 Channel Amplifier: The Onkyo TX-NR838 AV receiver features a 7-channel amplifier rated at 130 watts (into 8-ohms, at 20Hz-20kHz, with 0.08%, driving 2 channels). The AV receiver's amplifier employs WRAT, 3-Stage Inverted Darlington Circuitry, H.C.P.S, and Optimum Gain Volume Circuitry for dynamic, detailed, clear sound.
- Separates Construction: Unlike many A/V receivers, the audio and video processors, DAC section, networking, pre-amp, amplifiers, and power supply are all separated inside the Onkyo receiver to minimize electrical interference on audio signals.
- WRAT (Wide Range Amplifier Technology): WRAT is based around a low negative-feedback circuit topology that works to reduce signal noise and distortion across the frequency range. A "closed ground-loop circuit" design is employed, in which each circuit has a separate link to the power supply. This helps to cancel individual circuit noise and keep the ground potential free of distortion. High Instantaneous Current Capability (HICC) enables WRAT amplifiers to immediately cancel the speakers' reflex energy and instantaneously send out the next signal. The same high current better manages speaker impedance fluctuations, which can negatively affect performance.
- 3-Stage Inverted Darlington Circuitry: The AV receiver incorporates 3-Stage Inverted Darlington Circuitry into the front & center channels. This core Onkyo technology employs a low-NFB (negative feedback) design that makes the sound more natural.
- H.C.P.S. (High Current Power Supply): Under the anti-resonant cover of any Onkyo receiver, you'll instantly notice the High Current Power Supply (H.C.P.S.) transformer. With its huge, isolated power supply design and high-capacity filter capacitors, it delivers the large amounts of power necessary for reproducing the wide dynamics of movie soundtracks and the detail and clarity of your music.
- Optimum Gain Volume Circuitry: Optimum Gain Volume Circuitry adjusts the gain so that less than half the amount of attenuation is needed, ensuring the signal never comes close to the noise floor. This protects the signal against noise, resulting in a dramatically clearer sound.
Amplifier Assignment: The 7-channel amplifier can be configured in a variety of ways to match your type of speaker setup.
- Normal (7.2ch): The Onkyo TX-NR838 provides 7.2ch surround in your main listening area. You can choose either Surround Back or Front Height speakers (but not both).
- Front Bi-Amp (5.2ch): The Surround-Back/Front-High speaker terminals can be reassigned and used along with the Front terminals to bi-amp the front speakers, providing improved bass & treble performance. When bi-amping the front speakers the receiver is limited to a 5.2ch speaker system in the main room (no Surround Back or Front Height speakers)
- Powered Zone 2 (7.2ch + Zone 2): In this configuration, you can connect Front, Center, Surround, Surround Back (or Front Height), and Zone 2 speakers to the AV receiver. When Zone 2 is off, all seven channels will be used in the Main Zone. However, when Zone 2 is on, power to the two surround back (or front height) channels will be directed to the two speakers in Zone 2 and the Main Zone will receive only five channels of power.
- Dolby Atmos (w/ Firmware Update): The Surround-Back/Front-High speaker terminals are assigned to power a pair of overhead ceiling speakers or a pair of Dolby Atmos-enabled speakers to create 5.2.2ch Dolby Atmos surround sound. Zone 2 speaker can still be powered by the receiver in the configuration. When Zone 2 is off, all seven channels will be used in the Main Zone for Dolby Atmos. However, when Zone 2 is on, power to the Dolby Atmos channels will be directed to the two speakers in Zone 2 and the Main Zone will receive only five channels of power without Dolby Atmos.
192kHz/24-bit DACs + Dual 32-Bit DSP Processing: This Onkyo TX-NR838 is equipped with 192kHz/24-bit Burr-Brown DACs to decode and playback high-resolution recordings with less jitter and clearer sound. The receiver also employs powerful and highly accurate Dual 32-bit processing DSP's (Digital Signal Processor) for better surround sound reproduction.
PLL (Phase Locked Loop): PLL jitter-cleaning circuit technology reduces jitter by comparing the input and output phases of the digital signal and creating an accurate clock waveform. This enhances the precision of digital signal processing and noticeably improves audio quality. Jitter-cleaning technology works both for digital signals input via HDMI and for digital signals converted from analog signals inside the receiver itself
AccuEQ Room Calibration: Calibrating the sound to suit your room's acoustics is simple with Onkyo's AccuEQ auto-room calibration. Once you've connected your speakers, plug-in the included mic and wait a few moments as the TX-NR838 measures things such as speaker distance, type, crossover, and output, taking into account any reflections from your walls and floor. The system is designed specifically to by-pass your front left and right speakers. The system then optimizes the frequency response of the remaining speakers so you can enjoy balanced surround sound regardless of room shape or furnishing while retaining the characteristics of your front left and right speakers for optimum enjoyment
Multi-Channel Decoding Formats: The Onkyo TX-NR838 AV receiver supports the following multi-channel (Dolby Digital, DTS, Dolby Pro Logic) decoding formats.
- Dolby Digital: Dolby Digital, Dolby Digital EX, Dolby Digital Plus, Dolby TrueHD
- DTS: DTS, DTS-ES, DTS-HD Master Audio, DTS-HD High Resolution, DTS Express, DTS 96/24, DTS Neo: 6
- Dolby Pro Logic: Dolby Pro Logic II, Dolby Pro Logic IIx, Dolby Pro Logic IIz
Dolby Atmos: The TX-NR838 receiver is Dolby Atmos (5.2.2ch) compatible through a firmware update from Onkyo's website. Dolby Atmos combines traditional home theater speaker layouts with either ceiling-mounted speakers or new Dolby Atmos-enabled speakers to create a plane of sound above the listener. The impact of either in-ceiling or Dolby Atmos-enabled speakers is breathtaking. Your room fills with realistic, multidimensional sound that places you directly in the center of the entertainment experience.
- Ceiling Mounted Speakers: Ceiling speakers are used for maximizing effects in Dolby Atmos listening mode. Install these speakers midway between the position just above the listening position and the position just above the front speakers, or simply install them just above the listening position.
- Dolby Enabled Speakers: There are two types of Dolby Enabled
Speakers; one is to be placed on the top board of other
speakers such as front speakers and surround speakers; the other is integrated within the front or surround speakers. Dolby Enabled Speakers are designed with their output facing toward the ceiling to create an elevated audio effect in the Dolby Atmos mode by providing sounds echoing off the ceiling.
Dolby Surround: Dolby Surround offers an enhanced cinema experience to your Dolby Digital (Plus/TrueHD) and DTS (ES/HD) movie soundtracks using your existing 7.1ch or Dolby Atmos speaker setup. Dolby Surround enhances audio definition by improving the spatial dimension and overall audio definition of movie soundtracks. It does this by using four distinct surround zones that provide greater control over the exact placement of each detail in a movie sound track, so audio can be matched more accurately to the video on screen; this means more depth and greater realism for your movies. As a result, individual sounds are clearer and more distinct. It also improves the surround sound experience across the entire theater by widening the listening "sweet spot".
THX Select 2 Plus Certified: The TX-NR838 AV receiver is THX Select 2 Plus certified. Founded by George Lucas, THX develops stringent standards that ensure movies are reproduced in movie theaters and home theaters just as the director intended. From early design concepts to product rollout, THX works with its manufacturing partners at each step of product development. Every detail is meticulously mapped to the THX performance standards. And THX engineers spend countless hours testing and analyzing each product for sound quality, usability and interoperability. The result of this collaborative process is a THX Certified receiver, amplifier or pre-amplifier designed from the ground-up to present your favorite movies, music, and games in 5.1ch to 7.1ch surround sound loud and clear at studio reference volumes. THX Select 2 Plus is specified for rooms where the screen-to-seat viewing distance is 10-12' and the room volume is 3,000 cubic feet or greater.
- THX Surround EX: The THX Surround EX mode further expands 5.1ch sources for 6.1ch or 7.1ch playback.
- THX Loudness Plus: THX Loudness Plus compensates for the tonal and spatial shifts that occur when the volume is reduced by intelligently adjusting ambient surround channel levels and frequency response. With THX Loudness Plus, home theater audiences can experience the rich details in a surround mix at any volume level.
Onkyo Original DSP Modes: Onkyo's Original DSP Modes, combined with Dolby Digital/DTS/Dolby Pro Logic processing, produce more realistic, powerful sound effects for your movie and music sound tracks based on the type of content and your home theater setup. You can choose from the following:
- Orchestra: For classical or operatic music.
- Unplugged: For acoustic instruments, vocals, and jazz.
- Studio-Mix: Suitable for rock or pop.
- TV Logic: Adds realistic acoustics to TV shows.
- Game: The receiver offers four different Gaming modes - RPG, Action, Rock, and Sports.
- All Ch Stereo: Stereo sound from all speakers. Ideal for background music.
- Full Mono: All speakers output the same sound in mono.
- Theater-Dimensional (T-D): Theater-Dimensional circuitry takes the complexity out of conventional surround-sound setups and lets you experience the excitement of surround sound from as few as two ordinary speakers. Theater-Dimensional's unique multi-speaker modes let you place up to five speakers conveniently by the TV, for the most realistic virtual-surround sound possible.
Audiophile Listening Modes: The Onkyo TX-NR838 offers two audiophile listening modes which bypass the receiver's tone & DSP processing for higher sound quality performance. In Direct mode, audio from the input source is output without surround-sound processing. This mode delivers pure sound with minimum sound quality adjustment and filtration. In Pure Audio mode, the display and video circuitry are turned off, minimizing possible noise sources for the ultimate in high-fidelity audio reproduction.
Surround Parameters: The Onkyo TX-NR838 lets you tweak and fine tune specific surround sound modes to suit your preference.
- Dolby Pro Logic II Music Settings: While listening in the Dolby Pro Logic II Music format, there are three further enhancements you can adjust; Panorama: (broadens the front stereo image to the surround speakers to provide a wraparound effect), Dimension (allows you to move the sound field forward or backward), and Center Width (allows you to adjust the width of the center channel).
- Center Image: In the Neo:6 Music mode, the Center Image feature adjusts the output of the left and right channels relative to the center channel, allowing you to make the center channel more or less dominant as needed. This improves the image of the center channel, especially when the listener is off-center. Adjustment varies from 5 (nothing subtracted from the L/R channels) to 0 (L/R channel output is cut in half).
- Pro Logic IIz Height Gain: The Height Gain Control in Dolby Pro Logic IIz enables the listener to select how much gain is applied to the front high speakers. There are three settings, "Low", "Mid" and "High", and the front high speakers are accentuated in that order. While "Mid" is the default listening setting, the listener may adjust the Height Gain Control to their personal preference.
- Listening Angle: While listening in the Theater Dimensional mode you can adjust the listening angle to either Wide (if listening angle is 40°) or Narrow (if listening angle is 20°).
Audio Enhancements: The Onkyo TX-NR838 receiver provides various audio enhancements to deliver a high-quality listening experience every time.
- CinemaFilter: Using the CinemaFilter you soften overly bright movie soundtracks. Movie soundtracks are typically mixed for a large theater (relative to your home theater) with lots of soft seats and thick curtains on the walls. Home theater settings often lack these high frequency absorbing wall treatments, making the soundtrack sound too bright. CinemaFilter accounts for this and for many movies sounds more natural at home.
- Music Optimizer: The Music Optimizer function enhances the sound quality of compressed music files. The Music Optimizer function only works with PCM digital audio input signals with a sampling rate below 48kHz and analog input signals.
- Late Night Feature: The Late Night feature limits the dynamic range of Dolby Digital recordings. Limiting the dynamic range makes it easier to find a volume that ensures the quiet sounds are not too quiet and the loud sounds are not too loud for night time listening. This allows you to comfortably listen to without the need to constantly adjust the volume to keep from waking family/neighbors. The choices are: Off, Low, and High. This feature only works with Dolby Digital Encoded software and the depth of the feature will vary based on the individual software package.
Bass Management: The Onkyo AV receiver offers Tone Control and Phase Matching Bass technology to get the most bass impact out of your system.
- Tone Controls: You can independently adjust the Bass (50Hz) and Treble (20kHz) of the TX-NR838 from -10 to +10 dB.
- Phase Matching Bass: Onkyo's Phase-Matching Bass optimizes low frequencies while preserving mid-range clarity. This means that powerful bass plays back with clear vocals; it doesn't overpower them.
- Double Bass: You can also activate the Double Bass function in order to boost bass output even more by feeding bass sounds to the front left/right speakers, center-channel, and powered subwoofer.
Volume Setup: The Onkyo AV receiver provides the following volume settings.
- IntelliVolume: With IntelliVolume, you can set the input level for each input (+/-12dB) selector individually. This is useful if one of your source components is louder or quieter than the others. This function does not work in Zone 2.
- Maximum Volume: Use this feature to set the receiver's maximum volume level. This feature is useful to avoid turning the volume too loud by mistake. You can set the Max Volume from 30-79 (max), or Off (disabled).
- Power On Volume: Use this feature to set the volume level when the power is turned on. You can choose between Last (same as the volume when the unit was turned off), Min (0), or 1-79.
- Headphone Level: With this setting, you can specify the headphone volume (+/-12dB) relative to the main volume. This is useful if there's a volume difference between your speakers and your headphones.
Audio Inputs/Outputs: The Onkyo AV receiver offers a variety of analog and digital audio inputs/outputs.
- Assignable Digital Inputs: The Onkyo receiver is equipped with two optical digital inputs and three coaxial digital inputs. All digital inputs are assignable.

Convenience Features
On-Screen Menu w/ Setup Assistance: The Onkyo AV receiver offers an on-screen (GUI) menu system through its HDMI output. The simple on-screen display combines text and graphics that make setup and other operations extremely easy. The initial setup assistant takes you step-by-step through speaker configuration, source connection, remote programming, and network connection. If your TV is connected to the composite video or component video monitor output, you will need to use the AV receiver's front-panel display when changing settings.
Multi-Source/Multi-Zone: The TX-NR838 offers three Zones; a multi-channel audio/video system in your main listening room (Main Zone), a stereo audio or video system in a second room (Zone 2), and another stereo audio only system in a third room (Zone 3).
- Zone 2 Speaker- & Line-Level Output (Audio Only): Zone 2 features line-level and speaker audio outputs
for playback of a different analog source in a second room. This way,
Zone 2 can be powered by a separate amplifier (keeping 7.2ch playback in
your main room) or by the TX-NR838's built-in amplifier (limiting the main
room to 5.2ch). When powering Zone 2 with the receiver's
built-in amplifier, listening modes that require surround back or front
high/wide speakers are unavailable. You cannot power Zone 2 with the
receiver's built-in amplifier, if you are bi-amping your front speakers. The
volume of Zone 2 can be controlled from the receiver when using the speaker
outputs or line-level outputs, and from your add-on integrated amp when
using the line-level outputs.
- Compatible Sources: Tuner, Analog, USB, Bluetooth, and Network audio sources.
- Incompatible Sources: Optical/coaxial digital audio sources, HDMI sources, and any video source.
- Zone 2 HDMI Output (Audio/Video): The Onkyo receiver also
provides a Zone 2 HDMI output, so two different HDMI audio/video feeds can
be sent to two different displays at the same time directly from the
receiver (HDMI 1-4/Aux connected input sources only). HDMI Zone 2 will
output up to 4K video and 2-channel audio for the HDMI input source
selected.
- Compatible Sources: HDMI 1-4/Aux connected input sources only
- Incompatible Sources: Tuner, Analog, USB, Bluetooth, Network, and Optical/Coaxial Digital audio sources; plus analog video sources.
- Zone 3 (Audio Only): Zone 3 allows playback of a
separate analog source in 2-channel stereo in a third room of your home.
Zone 3 features line-level outputs only. This way, Zone 3 can be powered by
a separate integrated amplifier (keeping 7.2ch playback in your main room).
The volume of Zone 3 can be controlled by the AV receiver or your separate
integrated amp's remote.
- Compatible Sources: Tuner, Analog, USB, Bluetooth, and Network audio sources.
- Incompatible Sources: Optical/coaxial digital audio sources, HDMI sources, and any video source.
Notes: As for etwork, USB, and Bluetooth sources; you cannot select different inputs for the main room and Zone 2/3. For example, if a Network source been selected in the main room and then a USB is selected as playback source in Zone 2/3, the input in the main room will also change to the USB source. When listening to AM/FM radio, you cannot select different stations for the main room and Zone 2/3.
Whole House Mode: The Whole House Mode is useful when you want to simply add extra background music to your home party. This mode allows you to enjoy the same stereo music as the main room in separate rooms (Zone 2/3). The Whole House Mode selects the same input source for Zone 2/3 as the main room. During the Whole House Mode, stereo playback is automatically selected for all zones. The Main Zone & Zone 2/3 will play at the same volume level.
Name Edit: You can enter a custom name for each individual input selector and radio preset for easy identification. When entered, the custom name will appear on the display. This function cannot be used for the AM/FM, Network, USB, and Bluetooth input selectors.
Display Dimmer + Screen Saver: The display brightness has three settings; Dim, Dimmer, and Normal. If there is no video signal on the current input source and no operation for a specific time, a screen saver automatically comes on. You can set the time (3min/5min/10min/off) until the screen saver activates itself. Once active, the screen saver will go off and the screen will return to its previous state if the AV receiver is operated in any way.
Timers: The receiver features a programmable Sleep Timer and Auto Standby function.

Hybrid Standby: The Onkyo TX-NR838 features "Hybrid Standby" mode to save energy and provide greater levels of convenience. Hybrid Standby Mode provides "HDMI through" functionality and maintains a local network connection while the receiver is essentially powered down.

This is a great product to date. We have had this receiver for only two weeks and couldn't be happier. It was easy to install and easy to connect the remote to all of our devices (Apple TV, PS4, etc.).
