Take your home theater above and beyond with Dolby Atmos and DTS:X™
A technology that just made its debut in home theater receivers last year, Dolby Atmos creates the most lifelike, captivating surround sound of any audio format we've heard to date. If you're watching a plane take off onscreen, your ears will follow it down the runway along with your eyes, and as it flies overhead you might swear your hair is blowing back as it roars directly above you. The TX-NR747 supports a 5.1.2 Atmos setup. If you're ready to explore this new dimension in home theater sound, you'll just need to add a pair of in-ceiling speakers to your five-channel system, or pick up a pair of Atmos enabled upward-firing speakers to project sound off your ceiling and create the height effects that make an Atmos system so riveting.
Onkyo will release a firmware update in the summer of 2016 that will give this receiver DTS:X surround sound, an upcoming format which will use object-based processing similar to Dolby Atmos and overhead speakers for immersive home theater.
Endless streaming options
The TX-NR747's built-in Wi-Fi lets you access the music you have stored on your networked computer, plus you can take advantage of free Internet radio and other subscription-based Internet radio services like Spotify®, Pandora®, and SiriusXM® Internet radio. All of these options can be controlled with the Onkyo Remote app on your phone. Bluetooth lets you stream any music you listen to on your phone or tablet directly to the receiver for playback through your home speakers, and Apple AirPlay lets you send music wirelessly from a compatible Apple device or from any computer with iTunes®.
Great sound is key
Audio performance is at the heart of the TX-NR747's design. Onkyo's Wide Range Amplifier technology gives you smooth sound with minimal distortion for thrilling movie sound effects. Phase-matching Bass Enhancement lets you enjoy deep, thunderous low frequency effects while vocals and dialogue remain clear. Music aficionados will appreciate decoding for high-resolution DSD and FLAC files, along with other high-res formats. Onkyo's Music Optimizer helps improve the sound of compressed audio files and Bluetooth streams so you can hear your music the way it was meant to be heard. A premium 32-bit/384kHz (no, that's not a typo — color us impressed) digital-to-analog converter uses an exclusive low-distortion filtering technology to deliver crystal-clear reproduction of music and TV and movie soundtracks.
Enjoy your music in a second room
Ever wish you had a dedicated music listening room? It isn't hard to set one up with the TX-NR747's dual-zone audio capabilities. Powered Zone 2 outputs let you connect a pair of speakers for stereo sound in another room. You can also connect a stereo receiver through the line-level Zone 2 connection and use the 'NR747 as a preamp. Whole House Mode lets you play the same song in all zones, or you can listen to a different song in each room. Use the Onkyo Remote app to control audio content in different zones from anywhere in the house.

7 Channel Amplifier: The Onkyo TX-NR747 AV receiver features a 7-channel amplifier rated at 110 watts (into 8-ohms, at 20Hz-20kHz, with 0.08%, driving 2 channels). The AV receiver's amplifier employs WRAT, H.C.P.S, PLL Jitter-Cleaning Circuitry, and Optimum Gain Volume Circuitry for dynamic, detailed, clear sound.
- 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.
- 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.
- PLL Jitter-Cleaning Circuit Technology: PLL (Phase Locked Loop) 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
Amplifier Assignment: The 7-channel amplifier can be configured in a variety of ways to match your type of speaker setup.
- Normal (7.1ch): The Onkyo TX-NR747 provides 7.1ch surround in your main listening area. You can choose either Surround Back or Front Height speakers (but not both).
- Front Bi-Amp (5.1ch): 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 5.1ch speaker system in the main room (no Surround Back or Front Height speakers)
- Powered Zone 2 (7.1ch + 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 (5.1.2ch): 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 5.1.2ch 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.
384 kHz/32-bit Hi-Grade DAC: A premium-quality AK4458 digital-to-analog converter from Asahi Kasei implements unique low-distortion filtering technologies for clear sound, and unlocks the full potential of any audio format, including compressed, lossless, and hi-res audio (MP3, WMA, WMA Lossless, FLAC, WAV, OggVorbis, AAC, Apple Lossless, DSD 5.6 MHz, LPCM, and Dolby TrueHD).
Dual 32-Bit DSP: The Onkyo AV receiver employs powerful and highly accurate Dual 32-bit processing DSP's (Digital Signal Processor) for better surround sound reproduction.
THX Select 2 Plus Certified: The TX-NR747 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 feet and the room volume is 3,000 cubic feet or greater.
- 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.
- Boundary Gain Compensation: If your listening room layout (for practical or aesthetic reasons) locates most of the listeners close to the rear wall, the resulting bass level can be sufficiently reinforced by the boundary that the overall sound becomes "boomy". THX Select2 Plus receivers contain a Boundary Gain Compensation (BGC) feature to improve bass balance.
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-NR747 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-NR747 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
Immersive Surround Sound: The Onkyo TX-NR747 AV receiver goes beyond regular surround with the latest immersive surround sound formats - like Dolby Atmos, Dolby Surround, and DTS:X.
- Dolby Atmos: The TX-NR747 receiver is Dolby Atmos (5.1.2ch) compatible. 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.
- 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".
- DTS:X (Future Firmware Update): DTS:X will be enabled through an online firmware update later this year. DTS:X is the next generation object-based, multi-dimensional audio technology from DTS. Unbound from channels, DTS:X conveys the fluid movement of sound to create an incredibly rich, realistic and immersive soundscape - in front of, behind, beside and above the audience - more accurately than ever before. DTS:X offers the ability to automatically adapt the audio to the speaker layout that best fits your space.
- DTS:X Neural (Future Firmware Update): DTS:X Neural will also require the same future firmware upgrade as DTS:X. Further, DTS:X incorporates Neural:X, the latest spatial remapping technology from DTS, which provides a fully immersive output for all types of source content; this includes DTS bitstreams and non-encoded (PCM) data. Neural:X delivers a thrilling sense of immersive sound to your speaker layout regardless of the original source format. Click here for more information about DTS:X & DTS:X Neural.
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.
Direct Mode: 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.
Surround Parameters: The Onkyo TX-NR747 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).
- Center Spread: Adjusts the width of the soundfield of the front channels when playing in the Dolby Surround listening mode.
- 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-NR747 receiver provides various audio enhancements to deliver a high-quality listening experience every time.
- RE-EQ: Using the RE-EQ function, 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. RE-EQ 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, analog input signals, and Bluetooth audio.
- Dialog Control: You can increase the dialog
portion of the audio in 1 dB steps up to 6 dB so that you can make
dialog easier to hear over background noise. - 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-NR747 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.
- Digital Inputs: The Onkyo receiver is equipped with two optical digital inputs and one coaxial digital input. All three digital inputs are assignable.

Convenience Features
On-Screen Menu w/ Setup Assistance (HDMI only): 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.
Zone 2: In addition to the main listening room, you can also enjoy audio playback from a different source in another room of your home using the receiver's Zone 2. The receiver features Zone 2 line-outputs, as well as Zone 2 speaker terminals. By using the line-level outputs on the TX-NR747 you can connect an external receiver or integrated amplifier in a second room, allowing you to listen to 7.1ch or 5.1.2ch surround in the main room and play a different audio source in another room of your home.
