Yamaha XDA-QS5400RK MusicCast Multi-Room Streaming Amplifier

About The Yamaha XDA-QS5400RK MusicCast Multi-Room Streaming Amplifier

Specially designed for custom integration of whole home audio systems, the "QS" (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 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.

Ingenious Integration: 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.

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-optimise your 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 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.

A Family Like No Other: 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.

Stream It All: 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.)

Plays Nicely with Everything: 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.

3rd-Party Control: The QS supports IP control by 3rd-party control systems used in many of today's most advanced smart homes.

There's An (Amazing) App For It: 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.

Audiophile-Grade Amplification: 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).

Goodbye Ground Loop Hum: The curse of the custom integrator: 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.

High-Resolution Audio: Experience every detail of your favourite recordings. 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.

Uniquely Yamaha: 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.

Versatile Installation: Mount it in a rack with the included ears or remove the ears for shelf installations.

Custom-Friendly Connectivity & 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.

Unique Chime Generator: The 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.

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

Our Take On The Yamaha XDA-QS5400RK

On the surface of it, the XDA-QS5400RK doesn't look very inspiring. In fact it looks down right industrial. But that, dear customers, is exactly as intended. I'm sure we've all encountered those people who want nice sound, everywhere if possible, but don't want to see any audio gear or speakers. Well, this is the product for them, and you, if you happen to live with them. One (or more) Yamaha XDA-QS5400RK discretely positioned out of sight and a bunch of nice quality in-ceiling (or in-wall) speakers and you can have a whole house system that works and sounds a treat but looks virtually invisible. Sound good? Enquire about the Yamaha XDA-QS5400RK today.
