Surround yourself in rich, detailed 7.1 channel surround sound.

Our wave-front synthesis technology uses the full speaker array to accurately position sound in the room, delivering immersive audio with complete precision.

Cinematic S-Force PRO Front Surround

An immersive virtual surround sound experience. S-Force PRO Front Surround mimics the way the brain correlates sound sources to create proper volume, time lag, and sound wave spectrum – using only left and right speaker channels. By naturally emulating three-dimensional sound fields, you’ll be able to enjoy rich, high-fidelity audio across a wider listening area.

Dolby® TrueHD for sound as the director intended

Enjoy peerless audio quality with Dolby TrueHD, which delivers lossless sound across movies and music. By reproducing sound identical to original studio masters, it offers unparalleled audio fidelity for Blu-ray Discs and downloaded content.

DTS-HD™ for studio master precision

Enjoy precise, detailed home audio. With DTS-HD Master Audio, you’ll enjoy the original, uncompressed soundtracks on your favourite Blu-ray Discs and streamed movies – just as the director intended. DTS-HD High-Resolution Audio also offers intensely detailed reproduction for musical performances, allowing every note to shine with near studio-like quality.

Multiple HDMI ports for simple connectivity

USB port for High-Resolution Audio playback

Enjoy clear, detailed High-Resolution Audio playback. A USB port provides a stable connection for lossless audio, including DSD and 24bit/192kHz high bit rate audio codecs. Simply connect your USB drive or portable music device to enjoy optimum High-Resolution Audio playback. You can also play a variety of additional codes including MP3, AAC, and WMA.

4K pass through for 4K content

Maintain 4K quality from source to screen. The 4K pass-through feature allows 4K data to ‘pass through’ and be displayed on a 4K TV or projector, without compromising image quality. Giving you the pure 4K experience makes this sound bar the perfect partner for 4K-capable TVs and players, and a solid cornerstone for your home entertainment system for the future.

High-Resolution Audio for uncompromised sound

Experience digital music to the fullest with High-Resolution Audio. By capturing music at a higher rate than CD, increasing both audio samples per second and the bit-rate accuracy of each sample, High-Resolution Audio offers an uncompromised rendition of an artists’ music. Savour every breath and subtle movement for a truly emotional experience.

S-Master HX digital amplifier: utmost sonic purity

Enjoy the best High-Resolution Audio experience with the S-Master HX digital amplifier. Using a simplified, fully digital signal path and ultra-high frequency noise shaping, S-Master HX reproduces the subtleties and wide frequency range that music and movies demand. This includes the latest High-Resolution Audio formats, so you can enjoy music just as the artist intended.

DSEE HX restores your music files

Go beyond CD quality. DSEE HX builds on our proprietary DSEE technology, upscaling compressed audio files to a level that’s closer to High-Resolution Audio. By restoring the subtleties of the original recording that are lost during the compression process, DSEE HX delivers a rich, studio-quality audio experience for all your music.

ClearAudio+ enriches your music

Unique to Sony, ClearAudio+ automatically adjusts sound settings for an enriching listening experience. By bringing together expertise in digital signal processing technologies, ClearAudio+ is able to optimise audio to deliver a consistently clear, high-quality sound, whether you’re gaming or enjoying music and movies.

Coaxial speakers for full-range sound

Our newly-developed coaxial speakers allow exceptional audio performance from a slim, compact sound bar design. By combining a woofer and tweeter in a single two-way speaker unit, a wider frequency range can be reproduced. This ensures no detail is lost, taking your listening closer to the live performance.

Super tweeters for soaring highs

Experience pristine highs, whether it’s music or dialogue. Mounting Wide Dispersion Super Tweeters on the front of each speaker creates a wide sound field that maintains its quality across the entire room. High-frequency notes are reproduced in the clarity and detail of High-Resolution Audio, so you’ll be able to enjoy realistic and engaging sound wherever you sit.

Carbon Fibre diaphragm for rigid speaker construction

A carbon fibre diaphragm ensures each speaker can reproduce sound with minimal distortion across the entire frequency range. The rigid, stiff properties of carbon fibre make it an extremely strong material – which is ideal for driver unit cones. This allows air to move at low frequencies without distortion for sound reproduction that’s clear and detailed.

Magnetic fluid speakers: high power, small size

By eliminating conventional speaker dampers and replacing them with magnetic fluid speaker technology, the size of the speaker is significantly reduced without affecting its accuracy and detail. Originally developed for NASA, magnetic fluid technology means you can fit great-sounding speakers in a smaller space – ideal for thin televisions and other compact, premium speakers.

Enjoy higher quality Bluetooth® streaming with LDAC

LDAC is a new codec developed by Sony for the highest quality Bluetooth audio streaming.
