Yamaha MusicCast XDA-QS5400RK

Yamaha Professional MusicCast 4 Zone (8 Channel) Multi-Room Streaming Amplifier

The Yamaha XDA-QS5400RK (Quad Streamer) provides four zones of audio streaming and eight channels of high-performance audio amplification in an ultra-slim, 1U-high, rack-mountable enclosure. Expandable and extremely flexible, the QS works with the Yamaha MusicCast multi-room audio system, allowing it to be linked with home theatre AV receivers, sound bars and Hi-Fi gear in a wide variety of configurations.

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-optimise 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 to 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. With MusicCast as the backbone, you clients can access all of their favourite music, including built-in streaming services and music libraries on smartphones, tablets and network-attached storage devices.

Remember, thanks also to Yamaha's expertease - this MusicCast product will also enable you to simply link and share to other MusicCast devices on the same network. If your clients 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.

Internally the QS uses no ordinary amp, the QS employs ultra-efficient ICEpower integrated circuits to deliver eight channels of pristine, musically-dynamic digital amplification at 50 watts/channel (8 ohms) with an outstanding 10 Hz to 22 kHz (+0/-3 dB) frequency response and 106 dB signal-to-noise ratio. It is 4 ohm capable at 100 watts/channel and bridgeable to 200 watts/channel (8 ohms). Additionally - thanks to Yamaha's clever design, the QS can slay the curse of the custom integrator: The ground loop hum, a common and vexing side effect of connecting a bunch of electronics together in a rack. The QS takes care of it with a brilliantly-engineered differential circuit design. Sometimes it’s what you don’t hear that sounds the most amazing.

The QS supports high-res audio playback up to 192 kHz/24-bit, and employs the same premium ESS Sabre DACs (Digital-to-Analogue Converters) and PML capacitors used in our flagship AVENTAGE AV receivers. The audio performance of the QS is further enhanced with a suite of exclusive Yamaha technologies, including our Compressed Music Enhancer, Advanced Bass Extension Processing and volume adaptive EQ. The result – it always sounds great.

For added flexibility, the QS supports IP control by 3rd-party control systems used in many of today’s most advanced smart homes. 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. 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.

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. The QS also features dedicated 'Chime contact closure' inputs let you generate 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.

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. Access Basic or Advanced settings via a Web Setup menu and store commonly-used profiles for faster configuration of future projects.
