True Sound With Dolby Atmos®
Yamaha’s True Sound engineering draws on all we know about sound and sound field creation, now further enhanced with Dolby Atmos® ensuring you are fully immersed in the extraordinary universe of movies and music.
Experience The Unique World Of Surround Sound
From intense action scenes to absorbing dramas, enjoy and bask in the latest cinematic experience that fills every corner of your room with expressive sound. With its precision-crafted speakers and advanced high-quality audio reproduction technology, the sound field created by the SR-B40A envelops you and transports you deeper into the story as it unfolds on screen.
True Sound Just For You
Newly designed tone controls (via our dedicated app) allow you to tweak the sound to your own taste while staying true to the content. What you get is an expansive sound field with ideal tonal balance in which every element of the sound shines with stunning clarity, enhancing the unique qualities of all your entertainment.
Thrilling Room-Filling Bass
For an overwhelming sense of floor-trembling realism right in your own living room, the wireless subwoofer expertly creates the low-end punch and texture you need, to put you right in the heart of the action.
Clear Voice
Our Clear Voice technology has been improved to make human voices even more audible. Use the Clear Voice feature to hear every word – from YouTube videos to movies and shows, especially when background music and sound effects try to take center stage. 
Four Sound Modes
With four different sound modes, you can match the sound to your content and mood. Stereo mode works great for music and podcasts. Standard mode is ideal for TV programs. Try Game mode to immerse yourself in your latest battle, and use Movie mode to create an expansive theater experience.
Bass Extension
Whenever you want more bass, use the Bass Extension feature, for a broader and more muscular presentation. Enjoy content with more power and presence.
