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.

Yamaha MusicCast Multi-Room Streaming Amplifier

Expandable and extremely flexible, the QS works with the MusicCast multi-room audio system, allowing it to be linked with home theater AV receivers, sound bars and Hi-Fi gear in a wide variety of configurations.

XDA-QS5400RK MusicCast Multi-Room Streaming Amplifier (4 Zone, 8 Channel)

Designed for custom integration of a MusicCast multi-room audio system connected via Ethernet LAN in a rack or cabinet

Streams four zones of audio per unit, expandable to 32 zones with simultaneous playback in linked groups of up to 20 zones each

Eight channels of audiophile-grade Class D amplification assignable to any zone, bridgeable and 4-ohm capable, featuring a unique ground loop/hum-free circuit design

Built-in Pandora®, Spotify Connect, SiriusXM Internet Radio, SiriusXM Music for Business, TIDAL, Deezer, Napster and more, plus access to music libraries and linked external sources

Easy control via a free MusicCast app and 3rd-party control systems

1U high, rack-wide enclosure; removable rack ears and faceplate included

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 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 large areas in a home. The pre outs 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 theater to a bedroom TV system to in-ceiling speakers in the kitchen – can all work beautifully together.

Access all of your favorite music, including built-in streaming services and music libraries on smartphones, tablets and networked-attached storage devices.  (Streaming service availability varies by region.)

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 personalization features including the ability to assign custom images to rooms, and to rename, rearrange and hide sources.

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).

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.

Experience every detail of your 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.

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.

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.

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.

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 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.

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

Only 2" tall and 8-3/8" wide, it can be placed horizontally or vertically, allowing it to fit neatly in almost any space.

With the feet removed, the WXC-50 is only 1-5/8" high, allowing it to be placed on a rack shelf within a 1U high rack space. Two units can be placed side-by-side on a 19" wide shelf.

Yamaha’s relentless pursuit of sonic purity is clearly evident in the engineering of the WXC-50. The preamp circuitry uses the same high-performance ESS digital-to-analog converter (DAC) found in high-end Yamaha AV receivers and a proprietary power supply ground configuration prevents sound degradation. A 48-bit digital volume control provides much greater precision and quality than conventional controls. A highly-rigid metal chassis supplies the stability necessary for clear, powerful music reproduction.

The WXC-50 supports high-resolution audio –including FLAC/WAV/AIFF up to 192 kHz/24-bit, Apple Lossless (ALAC) up to 96 kHz/24-bit and DSD up to 5.6 MHz – for more accurate reproduction of sonic details, presence and atmosphere.

The Compressed Music Enhancer greatly improves sound reproduction from smartphones or other compressed sources, like MP3 files. Volume-adaptive EQ automatically adjusts the bass/treble balance according to the volume level. Advanced Bass Extension Processing provides a deeper, richer low-end sound — great for use with compact or in-wall speakers. Direct playback mode allows you to play back high-resolution audio sources just as they are, without any processing.

If you want to adjust volume from a connected Hi-Fi amp or AV receiver, the WXC-50 allows you to turn off "preamp" mode and use the device as a network audio player. Switching to "player" mode bypasses the volume control and any processing, allowing direct playback of high-resolution audio.

Pressing any button on the front panel turns the unit on and initiates playback of the previously selected source providing quick and easy access to your favorite music.

The WXC-50 also comes with an ultra-slim remote offering six presets, so you can quickly access your favorite Internet radio stations even when your smartphone or tablet’s not handy.

The WXC-50 supports professional-grade features including:

Convenient Connectivity with Select Yamaha Hi-Fi Amplifiers

The WXC-50 provides a convenient way to connect with select Yamaha Hi-Fi amplifiers that have main in and trigger inputs. When connected in the manner shown here, the Hi-Fi amplifier’s system power can be turned on and the volume can be controlled via the MusicCast app.

The WXC-50 consumes less than two watts of power in standby mode. When the power is on, power consumption is still a low 5 W, and even when used for long periods, power consumption is environmentally friendly. In addition, the Auto Power Standby feature lets you save energy by automatically turning the power off after two, four, eight or 12 hours.

Turn your entire home into a concert hall. Combine the world’s most advanced piano, the Disklavier ENSPIRE, with MusicCast to enjoy the sound and music of a real acoustic piano in any room of your home.

The WXA-50 amp can be used to power speakers for backing tracks in the same room as the Disklavier, while the WXC-50 preamp can be used to transmit both the piano sound and backing tracks to other rooms.

Specially designed for custom integration of whole home audio systems, the "AMP" serves as a companion amplifier for the Yamaha XDA-QS5400RK to expand speaker coverage and/or increase power output. It may also be used to expand secondary zone speaker cove

Yamaha Multi-Room Amplifier

XDA-AMP5400RK Multi-Room Amplifier (4 Zone, 8 Channel)

Works together with Yamaha XDA-QS5400RK to expand speaker coverage in custom integrated multi-room audio systems

Eight channels of audiophile-grade Class D amplification, bridgeable and 4-ohm capable, featuring a unique ground loop/hum-free circuit design

Four audio buses and included jumpers allow for wide variety of speaker configurations

Interlocks power on/off with XDA-QS5400RK via Trigger I/O

Integration-friendly features include audio sensing inputs, IR I/O and more

The XDA-AMP5400RK – the "AMP" – was conceived as a companion to the Yamaha XDA-QS5400RK as a way to provide additional speaker coverage and/or additional speaker output power in a custom integrated multi-room home audio system. It also pairs nicely with Yamaha AV receivers that offer Zone pre outs.

The AMP packs eight channels of audiophile-grade amplification into a remarkably-slim 1U-high enclosure, allowing you to fully optimize your valuable rack real estate.

Feed up to four sources from QS pre outs into the AMP – its four audio I/O buses can be patched together to handle a wide array of speaker/zone configurations. The AMP comes with a set of jumper plugs and cables, making it ultra-versatile right out of the box. The audio outs can alternatively be used to connect powered subwoofers or subwoofer amps.

Each of the four amplifier zones is also bridgeable, giving you the option to increase power output to select speakers if needed.

The AMP employs ultra-efficient ICEpower integrated circuits to deliver eight channels of pristine, musically-dynamic digital amplification 50 watts/channel (8 ohms) with an outstanding 5 Hz to 40 kHz (+0/-3 dB) frequency response and 108 dB signal-to-noise ratio. It is 4 ohm capable at 100 watts/channel and bridgeable to 200 watts/channel (8 ohms).

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 AMP 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 AMP employs a balanced audio circuit design and PML capacitors, which are also used in our flagship AVENTAGE AV separates. The result: greater realism and expressiveness for all of your favorite music.

When a QS and AMP are used together, simply wire the trigger ports to automatically power on/off the desired amplifier zones – no additional control interface is needed. The AMP also works great as a companion to an AVENTAGE AV receiver. When using the AMP with other sources, audio sensing inputs and an infrared I/O provide additional control flexibility.

The AMP is truly made for custom integration, with Euroblock-style speaker connectors and a detachable AC cable for smart connectivity.

Specially designed for custom integration of whole home audio systems, the "AMP" serves as a companion amplifier for the Yamaha XDA-QS5400RK to expand speaker coverage and/or increase power output. It may also be used to expand secondary zone speaker coverage for Yamaha AV receivers that have Zone pre outs.
