    • DTS:X: DTS:X will be enabled through an online firmware update coming 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.

    Post Decoding Formats: The Sony AV receiver supports Dolby Surround, DTS Neural:X, and DTS Neo:6 (Music/Cinema) to enhance 2-channel and multichannel decoding formats.

    • Dolby Surround: Dolby Surround offers an enhanced cinema experience to your 2ch or multichannel movie soundtracks using your existing 5.1ch, 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 Neural:X: DTS Neural:X will be enabled through an online firmware update coming later this year. 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.
    • DTS Neo:6: DTS Neo:6 is an advanced matrix decoder that takes any two-channel source (including television broadcasts, CDs and DVDs) and expands it into five or six channels. It also provides separate, optimized modes for stereo music materials and matrix surround motion picture soundtracks. DTS Neo:6 brings you a more revealing sound from ordinary stereo and a more expansive home cinema experience.

    Direct Modes For Higher Fidelity Sound: The Sony AV receiver offers two Direct audio modes for higher fidelity sound. The receiver's Analog Direct mode outputs audio from only the front left and right speakers without any tone or DSP processing; only the volume and front speaker balance adjustments are active. To further enhance sound quality, the receiver's Pure Direct mode not only bypasses the tone and DSP processing, but also turns off the front-panel display to suppress any noise which may affect sound quality.

    Special Sound Modes: Sony has developed new special sound modes for in-ceiling speaker installation and simulating a 7.1 channel surround sound system.

    • In-Ceiling Speaker Mode: This feature will virtually relocate the front and center in-ceiling speakers down to around the screen. That way, you'll hear the actors' voices coming from the screen instead of the ceiling. This mode also makes music sound more natural in a room with in-ceiling speakers.
    • Phantom Surround Back: A new feature called Phantom Surround Back provides a 7.1 channel surround experience with a 5.1 channel speaker configuration.

    Advanced Audio Settings: These advanced audio settings allow you to tailor the sound to your source content, listening conditions, and your personal preferences.

    • D.L.L. (Digital Legato Linear): The Digital Legato Linear function is a Sony proprietary technology that allows low quality digital audio signals and analog audio signal to be played back with high quality sound.
    • Sound Optimizer: The Sound Optimizer lets you enjoy clear and dynamic sound at low volume levels. It automatically calibrates the sound which cannot be heard well when you turn down the volume level. After Auto Calibration is performed, the sound level is optimized to suit your environment.
    • Dynamic Range Compressor: This feature allows you to compress the dynamic range of the sound track. You can select standard or maximum compression, or off (only works with Dolby Digital sources).
    • Center Lift Up: By using front high speakers, you can lift up the sounds of the center speaker to an appropriate height on the screen, allowing you to enjoy a more natural representation.
    • DTS:X Dialog Control: The DTS:X Dialog Control function is a function which adjusts the dialog levels during playback of the DTS:X stream. This function enables you to increase the dialog levels in contrast with the background sound and hear dialog easily even under noisy circumstances.

    • Equalizer: You can adjust the tonal quality (bass & treble level) of the front speakers from -6dB to +6dB, in 1dB steps.

    Analog & Digital Inputs: The Sony STR-ZA3100ES offers a variety of analog and digital audio inputs

    • Analog Inputs: The STR-ZA3100ES is equipped with four analog audio inputs which consist of stereo RCA jacks. There is no Phono input.
    • Digital Inputs: The receiver has two optical digital inputs and one coaxial digital inputs (all assignable). You can choose auto decoding or PCM 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. All of the digital audio jacks are compatible with 32 kHz, 44.1 kHz, 48 kHz, and 96 kHz sampling frequencies.

    Speaker Outputs & Pre-Outs: The Sony STR-ZA3100ES is equipped with binding post speaker outputs and 7.2ch pre-outs.

    • Binding Post Speaker Outputs: The receiver is equipped with binding post terminals for all speaker channels. The binding post terminals will accept bare wire, pin connectors, and banana plugs (dual or single). Use speakers with a 6- to 16-ohm impedance.
    • 7.2ch Pre-Outs: The AV receiver features 7.2-channel pre-outs (Front, Center, Surround, Surround Back/Height, and Dual Subs) for connection to external power amplifiers. The pre-outs are variable. For compatibility with dual subwoofer home theater systems, the STR-ZA3100ES features two non-discrete subwoofer outputs; the same signal is output from each sub output.
    Note: There is no headphone output jack on this receiver.

    ARC & eARC Compatible: Along with standard ARC (Audio Return Channel), the Sony AV receiver will support eARC (Enhanced Audio Return Channel) through an available firmware update. ARC and eARC allow audio to be sent from your compatible TV to the AV receiver through the same HDMI cable already being used to send audio and video to your television. eARC will support uncompressed audio formats like Dolby TrueHD, Dolby Atmos, DTS:X, & DTS HD Master Audio - where standard ARC is limited to Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.

    Note: Your TV will also need to support eARC or ARC for this feature to work. Some newer TVs will support eARC, but most TVs only support ARC.

    Video Section

    HDMI 2.0a: The receiver is equipped with six HDMI 2.0a inputs (5 rear/1 front) and two HDMI 2.0a outputs. All HDMI jacks support 4K,  HDR (High Dynamic Range), BT.2020 wide color spaces, 3D,  and Deep Color pass-through. HDCP 2.2 and 4:4:4 color subsampling is also support by all of the receiver's rear-panel HDMI jacks.

    • 4K/60Hz Pass-Through: 4K/60Hz pass-through allows the Sony receiver to receive ultra high-definition resolution video and pass the video signal to a 4K/60Hz compatible TV or display monitor.
    • HDCP 2.2: HDCP 2.2 is supported by all of the receiver's rear-panel HDMI jacks. HDCP 2.2 is short for "High bandwidth Digital Content Protection" and is used for 4K video copyright protection for compatibility with Ultra HD Blu-ray players and 4K Satellite/Cable providers.
    • HDR (High Dynamic Range): HDR (High Dynamic Range) reproduces a greater dynamic range of luminosity or brightness levels, bringing greater contrast & wider color spectrum to the screen. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth. Previously hidden areas of dark shadow and sunlight are now full of clarity and detail. This receiver supports the HDR 10 format right out of the box. It requires an already available firmware update for Dolby Vision and HLG.
    • 4:4:4 Color Subsampling: The receiver's rear-panel HDMI jacks support RGB, YCbCr 4:4:4 color subsampling for more vibrant and lifelike images, as well as YCbCr 4:2:2 and YCbCr 4:2:0 color subsampling. With 4:4:4, luminance (brightness) and chroma (color) are sampled at the same rate, resulting in an RGB color palette as big as the video sampling rate for a video image with more total colors, plus greater color accuracy and detail. The front-panel HDMI input only supports up to 4:2:0.
    • Wide Color Gamut (BT.2020): The BT.2020 color standard delivers a much wider color gamut and represents about 75% of the total visual color spectrum, while the current Rec. 709 color standard selected as the color space for HDTVs and early generation 4K Ultra HDTVs covers only 35% of the total visual color spectrum.
    Note: Use a premium high-speed 18Gbps HDMI cable for the best 4K/HDR performance.

    Dual HDMI Outputs: You can toggle or simultaneously output the same video between two displays, such as two televisions or a television plus a projector. Or, you can setup the second HDMI output as a Zone 2 output, so you can view a different audio/video sources in another room of your home (video is output at the resolution supported by both TVs).

    4K HDMI Upconversion & Upscaling: The Sony AV receiver's HDMI upconvert/upscale function improves image quality of non-4K sources to ultra-HD. Analog connected device signals (component/composite; up to 1080p) are converted to digital, upscaled to 4K, and output via HDMI, making one cable connection from the receiver to your TV possible. HDMI input video signals (1080p only) are also upscaled to 4K. The HDMI Zone 2 output does not support upscaling.

    Color Technologies: The Sony STR-ZA3100ES incorporates Triluminos Color, Super Bit Mapping, & Deep Color technologies for perfect color and smooth gradation.

    • Triluminos Color: The Sony receiver incorporates Sony's Triluminos Color technology to create a heightened sense of depth and incredibly true, natural shades of colors. Hard-to-reproduce reds, aqua blues and emerald greens are displayed beautifully, so landscapes and seascapes look more vivid. Faces look better too, with natural skin tones.
    • Super Bit Mapping: SBM (Super Bit Mapping) is a function that processes and outputs a smooth gradation video signal from the HDMI output jack.
    • Deep Color: The Sony receiver also supports Deep Color which allows the color depth of video signals passing through HDMI to be raised. The number of colors that could be expressed by 1 pixel was 24 bits (16,777,216 colors) with a standard HDMI jack. However, the number of colors which can be expressed by 1 pixel is 36 bits with a Deep Color enabled HDMI jack. Since the gradation of the depth of a color can be expressed more finely with more bits, continuous color changes can be more smoothly expressed.

    Other HDMI Features: Other HDMI features of the Sony STR-ZA3100ES receiver include HDMI Standby Pass-Through, AV Sync, and 3D video.

    • HDMI Standby Pass-Through: The HDMI Standby Pass-Through feature conveniently allows you to access all your HDMI connected devices without having to power on the receiver.
    • AV Sync: The audio output can be delayed so that the time gap between the audio output and the visual display is minimized. This is especially helpful when you are using a large flat-panel TV. When activated, the delay can be adjusted from 0-300 ms or set to Auto.
    • 3D-Ready: The Sony AV receiver supports 3D video pass-through (720p/1080p only) from connected 3D-compatible Blu-ray, games and broadcast devices to 3D-compatible HDTVs (all 3D components must be connected via HDMI). Special eyewear will be required for viewing 3D content.

    24p True Cinema Mode: The 24p True Cinema Mode allows you to watch movies at their native frame rate 24p format (24 frames per second) when paired with a 24p playback device like a Blu-ray Disc Player.

    Analog Video Inputs: The Sony STR-ZA3100ES features two component video inputs featuring an 80 MHz bandwidth, making them capable of supporting high-definition video signals (up to 1080i). The receiver is also fitted with two analog composite video inputs, one composite video monitor output, and a Zone 2 composite video output. The composite video jacks support 480i video signals only. The composite video monitor output and Zone 2 output can only output video from the receivers composite video inputs. The two component video inputs can be out from the receiver's HDMI outputs.

    Zone 2 (Line-Level or Speaker Outputs): Tuner, Analog, HDMI, and Optical/Digital input sources are supported in Zone 2 when using the receiver's Line-Level or Speaker output. The line-level or Speaker Outputs of Zone 2 only support 2ch PCM (not multichannel Dolby Digital/DTS). Using the line-level outputs, Zone 2 can be powered by a separate amplifier, keeping 7.2ch playback in your main room). Using the speaker-level outputs of the STR-ZA3100ES allows you to power Zone 2 from the receiver's built-in amplifier, limiting the main room to 5.2ch. The volume of Zone 2 can be controlled by the Sony receiver using either configuration or from your add-on integrated amplifier when using the line-output.

    Notes:
    • Only 2ch PCM signals are output to Zone 2.
    • Digital audio stream signals such as DSD and Dolby Digital are not output to Zone 2.
    • Multi-channel stream signals are automatically converted to 2 channels signals, and then output to Zone 2 if the same source signals as the main zone are selected in Zone 2.
    • If the digital audio signals input from the HDMI, coaxial and optical input jacks on the receiver are not output to Zone 2, set the audio output to 2ch PCM on the connected device.

    Zone 2 HDMI & Video Switching: In addition to sending audio to Zone 2, the receiver allows you to output video in the second zone through its HDMI and composite video Zone 2 outputs. Via the receiver's composite video Zone 2 output, you can watch a composite video input signal of the receiver in Zone 2 on a second TV. Via the receiver's HDMI Zone 2 output, you can watch either a composite, component, or HDMI video signal input into the receiver in Zone 2 on another TV. The HDMI Zone 2 will also output multichannel audio (up to 5.1ch) to your second zone's TV or AV receiver from any connected source; including Tuner, Analog, HDMI, and Optical/Digital sources.

    Note: The receiver cannot output a different analog signal to the HDMI Zone 2 while an analog signal of the main zone is being output from the main HDMI monitor out.

    Zone 3 Audio Only: Zone 3 allows playback of an analog audio source in 2-channel stereo in a third room of your home. Zone 3 only features stereo line-level outputs, so a separate power amplifier is needed to power the speakers in this zone. Tuner and Analog input sources are supported in Zone 3 (Video, HDMI, and Optical/Digital sources cannot be output to Zone 3). The volume of Zone 3 can be controlled by the Sony receiver or your add-on integrated amplifier.

    Convenience Features

    Advanced On-Screen Menu w/ Setup Wizard: You can display the receiver's on-screen menu on your HDMI connected TV screen and select the function you want to use from the on-screen menu using the included IR remote control. You can easily access and manage your input devices and settings with this intuitive 6-panel "activity based" on-screen menu. The STR-ZA3100ES on-screen, set-up wizard will take you through everything you need to create and control your home theater experience.

    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.

    Custom Presets: The Sony AV receiver features 4 Custom Preset buttons (Movie, Music, Party, and Night) on the remote control to make operating the receiver easier. Pressing a Preset button will automatically launch a number of operations that initiate play of the source controlled by that button; such as powering on the receiver, switching to the appropriate source input, and recalling the selected DSP surround mode.

    • Custom Preset 1 (Movie): Pressing the Custom Preset 1 button turns on the receiver and lets you access a video source (default BD/DVD) with its saved soundfield (default HD-D.C.S).
    • Custom Preset 2 (Music): Pressing the Custom Preset 2 button turns on the receiver and lets you access an audio source (default SACD/CD) with its saved soundfield (default HD-D.C.S).
    • Custom Preset 3 (Party): Pressing the Custom Preset 3 button turns the AV receiver's Zone 2 on automatically and simultaneously plays the same music in Zone 2 as the main zone (regardless of source or input); volume level will be the same in both Zone.
    • Custom Preset 4 (Night): Pressing the Custom Preset 4 button turns the AV receiver's sleep timer function on for 30 minutes and activates the receiver's Sound Optimizer.
    Note: These buttons can also be reconfigured to automatically select other sources and soundfields.

    Input Modes & Naming: When you connect components to both digital and analog audio input jacks on the receiver, you can fix the audio input mode to either of them, or switch from one to the other, depending on the type of material you intend to watch. You can enter a name of up to 8 characters for each of the receiver's inputs (except Tuner) and display the name on its display. This is convenient for labeling the jacks with the names of your connected components. 

    Volume Display: You can set the volume display on the TV screen and display panel. Choose between Relative (indicates the volume in dB) or Absolute (indicates the number of steps).

    Dimmer: You can adjust the brightness of the display in 3 steps; Dim Max, Dim Mid, and Dim Off.

    Sleep Timer: The unit may be set to automatically turn off after 30, 60, 90, or 120 minutes.

    Auto Standby: Auto Standby lets you set the receiver switch to standby mode automatically after 30 minutes when you do not operate the receiver or when there is no signal input to the receiver.

    Remote Control

    IR Remote: The supplied remote is pre-coded to control this Sony receiver, Sony TVs, Sony CD players, Sony DVD players and recorders, and Sony Blu-ray disc players and recorders.

    Bravia Sync (HDMI CEC): Sony's Bravia Sync feature allows you to easily manage Bravia Sync compatible Sony televisions and other Bravia Sync compatible Sony audio and video components, plus other brands of HDMI CEC compatible gear that are connected via HDMI with a single remote. By connecting audio/video components that are compatible with the Bravia Sync or HDMI CEC function using an HDMI cable, operation is simplified in the following ways.

    • One-Touch-Play: When you playback a component such as a Blu-ray Disc Player, the receiver and the TV are turned on automatically and switch to the appropriate HDMI input.
    • System Audio Control: While watching TV, you can select to output the sound from the TV speaker or the speakers connected to the receiver.
    • System Power Off: When you turn off the TV, the receiver and connected components are also turned off simultaneously.

    Control System Integration: The STR-ZA3100ES is controllable over IP, includes 12V trigger output, RS-232C port, and IR input/outputs for more installation options.

    • RS-232C Port: The STR-ZA3100ES includes an RS-232C port for connection to external whole-house control systems, from companies such as Crestron, Control 4, and Savant.
    • IP Control: You can control this AV receiver from a web control screen on your laptop, computer, tablet, or smartphone's web browser. The STR-ZA3100ES and your web browser device must be connected to the same home network.
    • IR In/Outs: The Sony AV receiver is equipped with one IR input and two IR outputs enabling you to operate components connected to the receiver behind a closed door.
    • 12V Triggers: The STR-ZA3100ES has three minijack outputs to send a 12-Volt DC turn-on signal to other components that accept a 12V trigger.

    Crutchfield asked  
    Why did you buy this?

    Replacement for a different Sony ES receiver in my Sony set-up. [ Jeffrey  Nov 11, 2018 ]
    In a recent move, the movers dropped my absolutely incredible Sony STR-V555ES receiver I'd had since April of 2001. For nearly 17-and-a-half years, that receiver provided flawless, powerful sound. That said, it was the second to the best ES receiver at the time, so I figured I'd continue the tradition by getting the current generation of its pedigree. [ Greg  Oct 09, 2018 ]
    I bought a previous Sony Home Theater Receiver in 2014 when I bought my first 4K TV. Unfortunately, the receiver can't do 4K pass-through. This one does support that, plus HDR10, DolbyVision and HLG. [ James  Jan 29, 2018 ]
    It is replacing a STR-DA 1800ES which i purchased from Crutchfield about 5 years ago. I want Sony for the Bravia Sync, SONY ES for the power, and this model for the updated capabilities. [ Victor  Jul 20, 2017 ]
    Upgrading from an STR DA5700es. Also need the new 4k and Dolby ATMOS for my home theater experience. [ Leonardo  Apr 21, 2017 ]

    1 question already asked

    Yes: "7.1.2Ch: A Dolby Atmos 7.1.2ch speaker configuration is based upon a traditional 7.1ch speaker layout (Front, Center, Surround, & Surround Back) complemented by two Front Height, Overhead, or Dolby Atmos-enabled speakers. In this configuration, the Dolby Atmos speaker channels are powered by a separate stereo amplifier connected to the receiver's "Height" pre-outs." You will find this information, and more, by clicking the "Details" tab on the receiver's main webpage and scrolling down below the "Features & Specs" table. There is no issue with signal delay when using the RCA-Pre-amp outputs. I hope that helps My bio: https://www.crutchfield.com/bio/Ryan [ Ryan  Mar 17, 2018 ]  Staff
