Answering the call for more immersive sound

Ever look up wistfully at the ceiling in your home theater and wonder, “Why can't I get sound coming from up there?” Well, your daydreams have come true with the Onkyo TX-NR737 and Dolby Atmos®. With a firmware update, this receiver will be equipped with Dolby's latest surround sound breakthrough. It allows you to project sound from above your seating positions, for a new level of immersion and realism with movie soundtracks. Dolby Atmos is just the beginning of this receiver's features: 4K upscaling with Marvell Qdeo™ video processing, HDMI 2.0 connectivity, wireless music options, and seven channels of slammin' power make this receiver an excellent upgrade to your old receiver or a great starting point for budding home theater lovers.

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-NR737 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-NR737. 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 restore musical enjoyment to compressed files and Bluetooth streams.

Emphasis on sound

The 'NR737 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. And 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 even DSD.

Add music to a second and third room

If you'd like to add speakers to an adjoining bedroom, kitchen, or porch, you can plan ahead with the TX-NR737. There are powered Zone 2 outputs, so you can connect an additional set of speakers for use in another room. There are also line-level Zone 3 outputs, so you can send audio signals to a separate receiver in a third room — a great use for your old receiver when you upgrade to the 'NR737. While the kids enjoy a movie on cable in the home theater, you can chill out on the porch and listen to music from Spotify® and still have different music playing in another room. There's also a second HDMI output for use in large rooms with both a projector and a TV.

Simple setup and control

The tiny microphone that's included with the TX-NR737 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-NR737 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, 3-Stage Inverted Darlington Circuitry, H.C.P.S, 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.
    • 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-NR737 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-NR737 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-NR737 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-NR737 AV receiver supports the following multi-channel (Dolby Digital, DTS, Dolby Pro Logic) decoding formats.

    Note: Dolby Digital and DTS listening modes can only be selected if your audio source is connected to the A/V receiver via a digital audio connection (HDMI, optical, or coaxial). To enjoy true 7.1ch Dolby Digital TrueHD and DTS-HD surround sound, the receiver must be connected to your Blu-ray player via HDMI.

    Dolby Atmos: The TX-NR737 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.
    Note: Globally, more than 100 cinema blockbusters have been released featuring Dolby Atmos soundtracks in the past two years, and many more are on the way. Major Hollywood studios are partnering with Dolby to create home video versions of both current box office releases and previously released favorites for release starting in 2014.

    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-NR737 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 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.

    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-NR737 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-NR737 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-NR737 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 one optical digital input and two coaxial digital inputs. All three digital inputs are assignable. You can choose auto decoding , PCM, or DTS for the digital audio inputs. Auto will decode the signal in its original form (Dolby Digital, DTS, PCM, etc), PCM decodes the signal to 2-channel, while DTS decodes only DTS formatted sources.
    • Phono Input: The Onkyo AV receiver is fitted with a Phono input and ground terminal for connection of a turntable (MM).
    • Binding-Post Speaker Terminals: There are color-coded binding-post terminals for all speaker connections - Front, Center, Surround, Surround Back/Front Height, and Zone 2. The binding post terminals will accept bare-wire, pin-connectors, and banana plugs (single/dual). Use 4- to 16-ohm speakers.
    • Dual Subwoofer Outputs: The receiver is fitted with two subwoofer outputs to connect dual powered subs for extra bass. The dual outputs share the same input signal and are not discrete.
    • Headphones: When headphones are plugged into the full-size 1/4" jack on the front panel, all the speakers are automatically muted.

All HDMI jacks will also support uncompressed standard or high definition digital video along with the following audio signals; 2-channel linear PCM, Multichannel linear PCM (up to 7.1ch), and Bitstream (Dolby Digital/DTS, etc.). Additional HDMI features include -

    • 4K/60Hz + HDCP 2.2 (HDMI 2.0): The TX-NR737's HDMI 3 input and main HDMI output are version 2.0 compliant; supporting 4K/60Hz video signal, 21:9 display format, and HDCP 2.2 DRM copy protection compatibility. By implementing these new HDMI technologies, the TX-NR737 will be able to support future 4K streaming content from internet service providers (like Netflix) and UHD terrestrial/satellite broadcasts (not yet available). The AV receiver's HDMI 2-4 inputs are also version 2.0 and support 4K/60Hz video signal, but do not support HDCP 2.2 DRM copy protection. The receiver's HDMI 5-7 inputs and sub HDMI output are version 1.4 and support up to 1080p video.
    • 3D-Ready: All HDMI jacks will accept 3D video from your 3D-ready Blu-ray player and output the video signal in 3D to your 3D-ready flat-panel television.
    • ARC (Audio Return Channel): The receiver's main HDMI output features ARC (Audio Return Channel). This feature allows audio to be sent from your compatible HDTV to your receiver through the same HDMI cable already being used to send audio and video to your HDTV. This eliminates the need for extra cables connected to your television. The sub HDMI monitor output does not support this feature.
    • Auto Lip-Sync: The Lip-Sync function can automatically synchronize HDMI audio and video (for any HDMI jack) that has gotten out of sync due to the complex digital video processing being performed by your HDMI-compatible TV. With HDMI Lip-Sync, the audio delay required to synchronize the audio and video is calculated and applied automatically by the AV receiver. You can also manually correct the audio delay from 0 (no delay) to 400 milliseconds; in 10 millisecond steps.

    Marvel Qdeo Video Chip for 4K Upscaling: The Onkyo TX-NR737 utilizes a Marvel Qdeo Video Chip for 4K upscaling and video processing. The Marvel Qdeo Video Chip produces quiet and natural video, free from noise and artifacts. Analog component/composite video signals are converted to HDMI, so you only need one cable to connect the receiver to your TV. 480i video from the receiver's component/composite video inputs and any HDMI video signal can be scaled to a higher resolution set in the menu. You can set the AV receiver to upscale analog and HDMI video to 480p, 720p, 1080i, 1080p, 4K, Auto (automatically scaled to the highest resolution supported by the display), or Through (no scaling). Upconversion and upscaling is only supported by the main HDMI video output.

    MHL-Compatible HDMI Port: The front-panel HDMI input is MHL compatible. This MHL compatible HDMI port provides easy, direct connection of MHL compatible Android smartphones. Playback of up to 1080p video and multi-channel audio from the phone is supported. The receiver will also charge your connected phone. Play, Stop, and other basic operations can be controlled from the AV receiver's remote control. Check here for a list of compatible MHL-enabled Android phones.

    Note: The front-panel HDMI input, along with the receiver's front-panel USB port can also be used to connect your Lightning or 30-pin connector Apple iOS device via Apple's Lightning Digital AV adapter or 30-pin digital AV adapter; you'll also need the USB cable that came with your Apple iOS device, and a HDMI cable (sold separately). This type of connection provides "screen mirroring", audio/video playback, and charging of your Apple iOS device through the Onkyo receiver and your HDMI-connected TV. All control of your Apple iOS device will be done through its own touchscreen (not the receiver). See AV adapter links for specific Apple iOS compatibility.

    HDMI Through: When enabling the HDMI Through function, regardless of whether the AV receiver is "on" or in "standby" both audio and video streams from an HDMI input will be output to your television, via the receiver HDMI monitor output. You can select between 3 HDMI Through functions modes.

    • Auto: Detects the signal and automatically selects the input sources.
    • Source: Selects the input source (BD/DVD, VCR/DVR, CBL/SAT, Game, PC, Aux, TV/CD, Port) for which the HDMI Through function in enabled.
    • Last: The HDMI Through function is activated on the input source selected at the time of setting the AV receiver to the "standby" mode.

    InstaPrevue: InstaPrevue technology provides a live video thumbnail of the available content on your devices connected to the receiver via HDMI. As a result, you can preview audio/video streams coming from up to five HDMI inputs previously assigned to input selectors on your HDMI connected TV. Even with multiple components connected to receiver through HDMI, you can easily switch between inputs as their previews are displayed on a single screen on your television. You can even use the InstaPrevue feature for Picture-in-Picture. You can specify the number of preview thumbnails, as well as their positioning on-screen.

    Note: If no video signal are present, the thumbnails will be filled in black. With 3D video signals, the image may not be properly rendered on the preview thumbnails of InstaPrevue.

    Analog Video Inputs: The receiver features three composite video inputs and one composite video monitor output which support 480i video signals only. There is one component video input and one component video output which support up to 1080i video signal. You must connect the receiver to your TV via composite and/or component video to view incoming video from the receiver's composite/component inputs.

    Picture Adjust: Using the Picture Adjust feature, you can adjust the picture quality and reduce any noise appearing on your TV screen.

    • Wide Mode: Auto, Full, Zoom, Wide Zoom, or 4:3.
    • Picture Mode: Custom (Brightness/Contrast/Hue/Saturation/Color Temp), Cinema (for movies), Game (for gaming), Through (changes resolution), Direct (no adjustment).
    • Picture Settings: Film Mode (video or film), Edge Enhancement (sharpens image), Noise Reduction (reduce noise).

    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.

    Note: Initial setup requires that the receiver be connected to your TV via HDMI for display of the on-screen menu. Many of the receiver's setup functions can only be found via the on-screen menu and not the front-panel display.

    Multi-Source/Multi-Zone: The TX-NR737 offers three Zones; a multi-channel audio/video system in your main listening room (Main Zone), a stereo audio only 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): Zone 2 allows playback of a separate analog source in 2-channel stereo in an additional room of your home. Zone 2 features line-level outputs and speaker outputs. This way, Zone 2 can be powered by a separate integrated amplifier (keeping 7.2ch playback in your main room) or by the TX-NR737'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 is controlled from the receiver when using the speaker outputs and from your add-on integrated amp when using the line-level outputs.
    • Zone 3 (Line-Level Output): 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 will be controlled by your separate integrated amp's remote.
    Note: Compatible Sources - Only Tuner, Analog, USB, Bluetooth, and Network audio sources can be sent to Zone 2 or Zone 3. As for Network, 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. Incompatible Sources - Optical/coaxial digital and HDMI audio sources are not output to Zone 2/Zone 3. You cannot output any video signal to Zone 2 or Zone 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.

    • Auto Standby: The AV receiver will automatically go into Standby mode, if there is no operation for 20 minutes with no audio/video signal input.

    You could hook your turntable up to any one of the RCA inputs on the rear of your receiver and/or the AUX on the front. If ur turntable has A moving magnet that means it gas a phono preamp built-in. If your turntable does not have a moving magnet, you'll need a commercially available phono preamp. If your turntable has a moving coil (mc) type cartridge, you'll need a commercially available MC head amp or MC transformer as well as a phono preamp. See your turntable's manual for details.

    NO, it does not. It does gets hot but not to the point of needing a fan if sitting on a shelf. But If mounted inside a cabinet or rack you might consider one if temps get high.

    No fan I have detected, but it doesn't seem to get as hot as my earlier model. I love the unit except the Onkyo dweebs dropped vTuner in place of yet another crappy music service. I hope they wake up soon with that decision. Hope this helps.

    Hi: I don't know if it has a fan or not. It runs only warm to the touch in an enclosed cabinet so if there is a fan it may not be triggered. I would check with Crutchfieldl or Onkyo for their response. Sidenote: This is an Excellent av receiver!

    No. I have mine inside a piece of furniture and it has been fine. Doesn't seem to be running very hot.

    Yes. I think it comes on when temperatures reach a certain level to cool the unit.

    Zone 2 Setup - I have set Zone 2 to powered in the speaker setup for speakers by my pool but cannot get them to work when I set to Zone 2 for FM or CD sound. Is there something I am missing?

    The obvious question is does any source work? If the other sources are working, i'd double check the input mapping.

    I love Onkyo but for their horrible HDMI hardware. I have a TX-NR509 recently out of warranty. Have video, no sound - on any HDMI function. Went to Google and apparently Onkyo has been ducking this issue for some time across several model lines - there are a humongous number of the same issue. Can anyone share their experience regarding this matter? I am considering the purchase of a TX-NR737 from Crutchfield but am hesitant. Thank-you.

    I want to thank all the respondents - every response was helpful. To clarify - I am getting video, no audio from the TX-NR-509 and the 'NET and Update" choices on the config screen are greyed out. Many, many exactly the same issues on Google. However because of the courteous and helpful responses I have elected to give Onkyo one more try. My TX-NR737 from Crutchfield should be arriving later today. And I am psyched. Thank-you all again.

    Had my 737 for several months now and love it. No problems with the HDMI connections. In fact I see an improvement in picture quality over my TX-SR805 which I purchased back in 2007 and is still in use with no problems with the HDMI.

    What issue are you having with the HDMI? The only problem I have is if I'm sliding the receiver around, the HDMI will temporarily lose the connection. Other than that, no issues. I had the same Onkyo receiver that you had and upgraded to the TX-NR737...I love it!! They improved on the NR509 and added more features. I am very pleased with it and for the price, wouldn't choose anything else.

    HI Hugh, Iam thoroughly happy with the Onkyo TX-NR737. I have no problems with any of the HDMI connections. Great surround sound. I added a pair of Dolby Atmos enabled speakers for an incredible immersion of sound. I am sure you would be very pleased with it's performance. Good luck. John.

    HI Hugh. That was my concern as well before I bought my NR737. I read about the older HDMI problems. I haven't had an issues with my NR737. This receiver offers quite a bit at this price point. My hope is that Onkyo fixed the previous issues with their HDMI. So far, so good.

    is this ONKYO TX NR737 compatible with SONOS connect component?

    Sonos Connect works great the the 737. You can use Toslink or Coax or RCA. The single problem is preemptive source switching. It's the achilles heel with Sonos. From the Sonos app, there is no way to have the receiver switch the the correct input.
    william  Jul 06, 2015

    Don't know, but Sonos advertises seamless operation with mainstream receivers so it should work with the Onkyo NR737.

    Sorry Rich E I cannot answer that question for you. I do not know if it is compatible with the SONOS connect component. I wish I could be more helpful.

    HI I just installed the TX-NR737 There is only one HDCP2.2 input (port 3) and one output ( MAIN). There are 4 inputs that support 4K The second HDMI output is the SUB and it doesn't support the HDCP2.2 Marian

    Hi Matteo, From what I understand, the only HDCP 2.2 input is HDMI input #3. and the main HDMI output.
    marvin  Feb 03, 2015

    It appears that input 3 and the main output support HDCP 2.2 devices. Since I don't have any device that requires that decoding I can't test this.
    jerry  Feb 03, 2015
    Q
    Why would they include support for hdcp 2.2 on only 1 HDMI input? Eventually, people will have a blueray, cable box, etc... which will all require hdcp 2.2 HDMI input. Am i missing something?

    I forwarded your question to an Advisor and they responded with the following: I do not have an official answer as to why only one input would support HDCP 2.2 but I would imagine it has to be a cost benefit decision that them and the other manufacturers who have HDCP 2.2 compliant inputs seem to have made. I think they are most likely responding to the need for one input now and will grow as time goes by. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.

    I am considering this for the atoms processing but have a question about the ceiling speaker's. I have cathedral ceilings and my only available surround/viewing layout is in the same direction as the peak of the roof. When I install the ceiling speaker's one may be 9' and the other 10' (left and right), can the system be adjusted to account for the two different heights? I know this isn't ideal but my options are limited.

    yes. The system will auto adjust or you can enter the distances manually. I prefer the manual method.

    You always have the option of using Atmos front speakers that have the high directional speakers that set on top of them. The sound is deflected off the ceiling no need to cut the ceiling.
    doug  Aug 15, 2015

    I don't use ceiling speakers. My system is just a robust 5.1, but I have to believe that when you first set your system up, using the provided microphone for audio system calibration, the Receiver should be able to adjust fairly well to the 1' difference between the two ceiling speakers.
