7.2 channels for deeply immersive surround sound

Lose yourself in every soundtrack thanks to 7.2 channels of room-filling surround sound, with 110 W of power per channel. You can connect up to two active subwoofers for even bass distribution around the room. So whether you’re watching movies, playing games, or listening to your favorite songs, you’ll enjoy a next-level entertainment experience.

7.1.4-channel surround immersion with Phantom Surround Back

Defy space restrictions and experience full 7-channel surround sound, including 4 overhead speakers, with the Phantom Surround Back speaker setting. It simulates the audio experience of physical surround back speakers.

Dolby Atmos

Atmos treats sounds as separate objects, releasing them from typical channels to move freely around and even above you, for deeply immersive surround sound.

In-ceiling speaker mode

Easily configured during setup, In-ceiling mode relocates front speaker audio so dialog sounds as if it’s coming from the screen, instead of from above.

Seamless auto-calibration

DCAC EX uses a stereo mic to measure speaker positioning down to the nearest centimeter, before automatically adjusting frequencies, phase, and delays for better sound positioning. It then tunes your speakers using a 31-band EQ, for a listening experience that’s tailored to your room.


DTS:X can create an unlimited number of audio objects which adapt to your speakers in real-time, to get the biggest impact out of every movie soundtrack.

Enjoy consistent 4K content

Maintain 4K quality from source to screen—the 4K pass-through feature allows data to pass through the receiver without compromising image quality, and is HDCP 2.2-compatible.

See more detail with 4K upscale

Video upscaling gives you higher quality and more visible detail, so you can see more detail in everything.

6 x HDMI inputs, 2 x HDMI outputs

Bring all your home theater together. With 6 HDMI inputs, you can connect an Internet TV box, Blu-ray Disc™ player and games console all at once, and still have room to expand.

Web browser configurable

View, program, and edit your receiver settings from your computer, smartphone, or tablet. Just enter the receiver’s IP address into your browser.

Connect multiple remotes

Discrete IR codes let you connect multiple third-party and independent remotes, for easy and versatile control.

See clearly with HDR (High Dynamic Range)

By supporting HDR signal pass-through, you can enjoy the incredible jump in image contrast and brightness it brings—and the additional shadow detail and highlights further enhance picture detail and bring colors to life. Latest HDR standards such as HDR10, HLG (Hybrid Log-Gamma), and Dolby Vision ™ are supported.

Experience cinematic IMAX sound

This Sony receiver is an IMAX enhanced product, ready to deliver the highest standard of sound and clarity. Take comfort in knowing you’ll be enjoying a fully cinematic audio experience at-home with this receiver, that takes full advantage of IMAX enhanced content.

Remote monitoring with ihiji

Make your installer more efficient with ihiji, a cloud-based service that monitors your receiver’s power status, temperature, and more.

Music Connect

Music Connect allows Z-series AV receivers to slave to the HAP-Z1ES Hi-Res Audio player and other networked music players. So you can combine the power of an ES-grade multichannel sound system with the flexibility of today’s wireless multi-zone music systems.

8-Port Gigabit Ethernet switch

An 8-Port Ethernet switch lets you connect to computers, servers, or media boxes. Two of the ports support Power over Ethernet.

Simple control with a Graphic User Interface

Easily set up your receiver and navigate settings from the home menu. Control what you watch, see which devices are connected, and choose how you want to listen with preset sound modes.

Frame and beam chassis

The STR-ZA series chassis uses a frame and beam design with all four corners embossed to better support the power transformer and heat sink. This minimizes external sound pressure so audio is more focused, responsive, and powerful.

Power amplifier

For greater stability and output power, a glass-epoxy circuit board is used. Unlike cheaper resin boards, internal vibrations are reduced for less distortion, just clear high power from each of the discrete amplifiers.

Class-leading high-purity pre-amplifier

The new pre-amp goes way beyond other receivers in this class for optimum High-Resolution Audio delivery. A single-point ground and independent power supply promote purer sound with less interference.

One-cable HDMI eARC

With HDMI eARC, you can enjoy the latest high bitrate surround sound formats, like Dolby Atmos® and DTS:X®, from your compatible TV.

Heat sink design

Newly designed fins maximize air intake, helping the amplifier circuit withstand high sound pressure and keep cool.
