Yamaha WXA-50DS Wireless Streaming Amplifier with MusicCast
Audiophile Sound, Exquisite Design
The WXA-50 features a solid metal body with an aluminum cover and a slim, compact design that fits just about anywhere. Under the hood, you’ll find high-performance components and advanced circuitry that deliver powerful, sonically-pure amplification.
Control at Your Fingertips
The free MusicCast controller app puts control of your wireless system in the palm of your hand. Use the MusicCast Controller app to operate the system and change settings, select your sources and control music playback.
MusicCast
MusicCast makes it easy to bring music to every room in your home wirelessly with playback controlled by a simple app. Start with a MusicCast capable A/V receiver in your main entertainment room for the ultimate home theater experience, then add MusicCast speakers, sound bars or Hi-Fi components in other rooms wirelessly.
Bluetooth and AirPlay
Stream virtually any audio source via Bluetooth as an input to the WXA-50. Bluetooth sources can be redistributed through Wi-Fi to other MusicCast devices. Or stream using AirPlay from an Apple device to a single unit.
Slim, Compact Design
Only 2" tall and 8-3/8" wide, it can be placed horizontally or vertically, allowing it to fit neatly in almost any space.
Rack Shelf Friendly
With the feet removed, the WXA-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.
Superior Audio Technology
Yamaha’s relentless pursuit of sonic purity is clearly evident in the engineering of the WXA-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.
High-Resolution Audio
The WXA-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.
Yamaha Proprietary Sound Processing
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 provides a deeper, richer low-end sound, making it great for use with compact or in-wall speakers. Direct Mode allows you to play back high-resolution audio sources just as they are, without any processing.
One-Touch Controls
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 WXA-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.
Power Saving
A power management function automatically switches to standby mode. It can be set to two, four, eight or twelve hours or turned off. Power consumption during standby is only 15W, resulting in great energy savings.
Disklavier ENSPIRE
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.
With a firmware update, the WXA-50 amp can be used to power speakers for backing tracks in the same room as the Disklavier.
