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 (Available Firmware Update): 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.

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.

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.

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.
