Designed from the ground up for custom installation, the “QS” represents the ultimate integrated solution for filling every room in a home with extraordinary sound.
The QS packs four rooms of audio streaming and eight channels of audiophile-grade amplification into a remarkably slim, 1U-high enclosure, allowing you to fully-optimize your valuable rack real estate.
Multiple QS units can be used together to expand up to 32 zones with simultaneous playback of linked groups up to 20 zones each. In addition, the QS offers four zone preouts that enable it to be combined with the Yamaha XDA-AMP5400RK, a companion multi-room amplifier, to provide more power or more speaker coverage for large areas in a home. The preouts may also be used to connect powered subwoofers or subwoofer amps.
As a member of the MusicCast family, the QS integrates seamlessly with Yamaha AV receivers, sound bars and more. Now everything – from a surround sound home theatre to a bedroom TV system to in-ceiling speakers in the kitchen – can all work beautifully together.
Access all of your favourite music, including built-in streaming services and music libraries on smartphones, tablets and network-attached storage devices.
(Streaming service availability varies by region and may change or be discontinued without notice.)
Want to hear TV sound or vinyl records throughout the home? Link to a MusicCast receiver, sound bar or turntable to access audio from virtually any source.
The QS supports IP control by 3rd-party control systems used in many of today’s most advanced smart homes.
It’s also easy to set up and control with the free MusicCast app, which offers unique personalisation features including the ability to assign custom images to rooms, and to rename, rearrange and hide sources.
