Sony HT-A9 4.0.4-Channel Wireless Home Theater System
Enjoy an immersive wireless surround sound experience with the Sony HT-A9 4.0.4-Channel Wireless Home Theater System. It requires just one HDMI cable from your TV to transmit audio to the speakers wirelessly, with just one power cord for each speaker and the control unit. Onboard Wi-Fi connectivity powers Apple AirPlay 2 and Spotify Connect for convenient web streaming; Bluetooth is also onboard for wireless streaming from your compatible devices. It supports numerous Dolby and DTS audio formats, including Dolby Atmos and DTS:X, and can be controlled by your compatible TV's remote control, the included remote control, or via the Google Assistant.
360 Spatial Sound that Adapts to Your Environment
360 Spatial Sound Mapping technology creates up to 12 phantom speakers from just four real speakers. Surrounded on all sides by multiple phantom speakers within an optimized sound field, you'll hear every flap of wing and gust of wind with incredible intensity. It's like you and your living room are inside the movie.
Flexible Layout for Any Situation
Reduce clutter and enjoy a simple setup without a need for extra cables. The speakers included with the HT-A9 wirelessly connect to the control box, allowing you to place them anywhere in the room. Sound Field Optimization allows you to have the speakers at different heights and distances and will measure the position of each speaker to create the best sound for your room.
Sound Field Optimization
Activate Sound Field Optimization any time by performing Easy Setup from the home menu on the TV screen. The HT-A9 intelligently measures the distance between speakers and ceiling for smart and easy set up.
Connect Wirelessly
Place the control box near the TV and link up via HDMI. The four speakers connect to the control box wirelessly, so there are no cables across your living space.
Innovative Speaker Design
The speakers are designed with leading-edge technologies to deliver the supreme sound quality and wide directivity required for 360 Spatial Sound Mapping.
X-Balanced Speaker Unit
The unique rectangular shape of the up-firing speakers and front-firing wide-directivity woofers maximizes the diaphragm area for richer bass. It also reduces driver excursion while maintaining sound pressure, resulting in less distortion and greater vocal clarity.
Movies and Games Feel Real
Support for 8K UHD, 4K/120 passthrough, and Dolby Vision brings vivid visuals and quality sound to shows, movies, and fast paced video game play.
Immerse Yourself in Supreme Music Quality
Enjoy music the way the artists truly intended with High-Resolution Audio for crystal-clear precision. Or discover a new way of listening with 360 Reality Audio for a truly immersive live concert or studio session experience. With the HT-A9, your music comes to life like never before.
Real-Time Restoration of All Your Compressed Files
Using Edge-AI (Artificial Intelligence), DSEE Extreme (Digital Sound Enhancement Engine) upscales compressed digital music files in real time. Dynamically recognizing instrumentation, musical genres, and individual elements of each song, such as vocals or interludes, it restores the high-range sound lost in compression for a richer, more complete listening experience.
Omnidirectional Block Design
The HT-A9 is designed using the Omnidirectional Block concept. The cylindrical shape represents a single solid block providing 360 spatial sound. It fits perfectly against the wall with a flat rear surface. The light pearl gray color blends well with walls, shelves, and other interior elements.
Enjoy Movies Like Never Before with 360 Spatial Sound
A clever algorithm adds overhead, all-encompassing sound to conventional surround soundtracks and even stereo audio, converting everything you listen to (via HDMI) into immersive 360 Spatial Sound experiences. Just press the Immersive AE button on the remote to activate.
Voice Control
Connect to your home's other devices with the Google Assistant or Amazon Alexa (via a future planned firmware update).
Set Up in Seconds
The HT-A9 is almost ready to go straight out of the box. Simply plug it in, connect to your TV using HDMI, and power it on. With LAN, HDMI in, and HDMI out (eARC), you're all set to enjoy a new spatial surround sound experience.
Easy Listening
It's never been easier to listen to your favorite tracks. The HT-A9 supports audio streaming via Bluetooth, Wi-Fi, Chromecast built-in, Spotify Connect, and Apple AirPlay 2.
Pairs with Sony TVs
When paired with a BRAVIA TV, the HT-A9 brings you the ultimate immersive audio-visual experience.
Even More Immersion with Acoustic Center Sync
When connected with the supplied cable to a BRAVIA TV, the TV's speaker plays the center channel role in your home theater system and part of the 360 Spatial Sound Mapping setup. This enables sound to precisely match what's on the screen for a truly immersive experience. With Acoustic Center Sync, you'll hear dialogue from exactly where the character is standing in the scene. Action and sound are precisely aligned so your viewing becomes much more immersive.
Effortless Control with BRAVIA TVs
Everything links up perfectly when connected to the new range of BRAVIA XR TVs. Control sound settings and volume using only the TV remote and easily check the status of the audio system while watching your favorite programs. With an integrated UI, home theater system settings automatically appear on the BRAVIA TVs Quick Setting menu.
Boost the Bass with an Optional Subwoofer
Adding an optional subwoofer to your system to handle low frequencies allows the system to reproduce sounds with greater impact and power than before. Two models are available, designed to bring out deeper bass, more voice clarity and extra fidelity in everything you listen to.
