Seamless Integration
Designed with the custom-install space in mind, Yamaha offers custom drivers for Control4 and other leading control systems for most of their product lineup. Plus, SnapAV will soon deliver the deepest third-party OvrC Pro integration to date, with enhanced diagnostic data on Yamaha products. And with Google Assistant and Alexa compatibility, integration has never been easier.  
Ingenious Integration
Designed from the ground up for custom installation, the “QS” represents the ultimate integrated solution for filling every room with extraordinary sound.
Slim Yet Powerful
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 valuable rack real estate. 
Expands Easily
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 pre outs 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 larger installs. The pre outs may also be used to connect powered subwoofers or subwoofer amps.
3rd-Party Control
The QS supports IP control by 3rd-party control systems used in many of today’s most advanced smart home integrations. 
High-Resolution Audio
Give your client every detail of their favorite recordings. The QS supports high-res audio playback up to 192 kHz/24-bit, and employs the same premium ESS Sabre DACs (Digital-to-Analog Converters) and PML capacitors used in our flagship AVENTAGE AV receivers. 
Versatile Installation
Mount it in a rack with the included ears or remove the ears for shelf installations. The included magnetic faceplate discourages tampering and provides the perfect cosmetic finish.
Custom-Friendly Connectivity and Control
The QS is truly made for custom integration, with Euroblock-style speaker connectors, dual RJ-45 Ethernet ports and a detachable AC cable for smart connectivity, and IP, IR and 12 V Trigger Out jacks for versatile control.
Three Ways to Handle External Sources
In addition to supporting external sources through linking with MusicCast receivers and sound bars, the QS offers an Aux input that can be selected for playback in any zone and a Cut-In input that automatically senses an input signal and temporarily overrides the selected source. This gives you flexibility to integrate media players, CD changers or even paging systems. Thru-Outs let you set up a bus to additional QS units.
Stream It All
Give your client access to all their favorite music, including built-in streaming services and music libraries on smartphones, tablets and networked-attached storage devices. *Streaming service availability varies by region.
Web Setup
Access Basic or Advanced settings via a Web Setup menu and store commonly-used profiles for faster configuration of future projects. 
Unique Chime Generator
The Chime contact closure inputs let you integrate a doorbell chime or, for example, an alert for a gate from a common switch. Output zones and chime sound selection can be configured using the Web Setup.
