Immersive sound in a tidy package

Yamaha’s MusicCast BAR 400 is compact in size, but it is chock-full of features.

If you want room-filling sound without the hassle of lots of speakers, Yamaha’s MusicCast BAR 400 is an elegant solution. Its low profile and streamlined design will slip easily into your home’s decor, but the upgrade to your TV’s audio will definitely make an impact on your binge-watching game.

Clear Voice processing brings speech to the forefront so that dialogue is easier to hear and understand, while DTS Virtual:X digital signal processing broadens the soundstage for an even more immersive cinematic experience.

The included sub has a 6-1/2” woofer to add low-end punch to your movies, shows, and music. Plus it’s wireless — so you can park it in the most convenient and best-sounding spot. Just remember that it needs AC power.

How does DTS Virtual:X work?

Many sound bars simulate Dolby Atmos or DTS:X by bouncing sound off your walls and ceiling. That’s not what’s happening here. DTS Virtual:X uses “spatial audio techniques” to make it seem like the sound is all around you. Incredibly sophisticated audio delays and adjustments create a larger, wider soundstage. That includes overhead atmospheric effects like leaves rustling on a tall tree or birds chirping above.


Surround yourself

Virtual surround sound has come a long way, but there’s just no substitute for the real thing. So if you want an even more immersive experience, you can add one or two MusicCast 50 speakers or a pair of MusicCast 20 speakers behind your viewing area to deliver complete wraparound sound effects.

Plenty of options for music, too

The MusicCast BAR 400 offers a variety of options for streaming your content, including Bluetooth®, Wi-Fi®, Apple® AirPlay®, and Spotify® Connect. It even supports high-resolution audio formats up to 24-bit/192kHz. And it’s easy to select and control your music using the free Yamaha MusicCast app.

Part of a whole-home audio system

MusicCast uses your existing Wi-Fi network to stream music wirelessly throughout your home. Expand your system by adding compatible speakers, and you can play different music in each room, or group your speakers so they all play the same thing. The system is also Alexa-compatible, so if you have an Amazon Echo device, you can control it with your voice.
