Product Information

Supercharge Your Favorite Speakers with MusicCast Streaming Audio

Connect a pair of your favorite speakers to the Yamaha WXA-50 stereo amp, then use your existing Wi-Fi network to access all of your music from a simple app. Add other MusicCast speakers, sound bars or receivers for wireless multiroom audio playback. Great for use with in-ceiling and outdoor patio speakers.

  • High-performance design with premium audio components
  • Extremely versatile control and connectivity options
  • Access to your music library, Pandora®, Spotify, Rhapsody® and more
  • MusicCast app for Apple® iOS and Android™ devices
  • Conveniently slim, can be placed horizontally or vertically

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

Connect the WXA-50 to any pair of traditional wired speakers (bookshelf, tower, in-ceiling or outdoor speakers), then download the free MusicCast app to connect it to your existing home Wi-Fi to create a powerful streaming audio system.

Quickly select sources, browse your music library and control playback right from your smartphone or tablet. You can also control sound EQ settings from the app.

All Your Content

Access streaming music and Internet radio stations, music files on your mobile devices and computers, Bluetooth® sources and external sources such as a TV, Blu-ray Disc™ player or even a turntable.


A single WXA-50 can be used with speakers to create a standalone streaming audio system or multiple units can be used throughout the home. Play different music in each room or get everyone listening to the same thing. It can also be used with other MusicCast speakers, sound bars, AV receivers or Hi-Fi gear, providing more options and versatility than ever before.

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 — 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.

Pro-Grade Connectivity and Control

The WXA-50 supports professional-grade features including:

  • High-quality binding posts
  • Wired Ethernet port
  • Wireless off switch
  • Optical and analog inputs
  • Subwoofer out
  • Trigger in/out
  • Remote in
  • Low Power Consumption

The WXA-50 consumes less than two watts of power in standby mode. When the power is on, power consumption is still a low 15 watts. In addition, the Auto Power Standby feature lets you save energy by automatically turning the power off after two, four, eight or 12 hours.

Almost perfect
Very good, reliable. The only draw-back which I noticed in daily-basis usage is lack of possibility to voice control (even over google-home and spotify integration).

Recently bought my second one
The second one was harder to set up but fortunately the helpline led me through it. There were some wi-fi wrinkles missing from the instructions. Once it was up and running, I have found it easy to use. I'd willingly get a third if I had a use for it, unless I could find something similar at a more reasonable price.

WXA-50 MusicCast Wireless Streaming Amplifier
I love this amplifier. I am using it to drive two outdoor Definitive Technology AW5500s. It provides plenty of power to disturb the neighbors, if I choose to, which I will not. I am running it wired, so I cannot comment on the WIFI capability.
I knocked it down 1 star due to the price, the fact that it runs a bit warm and the remote that just feels very cheap. Hopefully the heat will not be a long-term issue.

Excellent amp
I have 1 of these and 2 of the WXC Streamers and a Aventage 2050. Excellent pieces with fantastic sound. I find the Musicast app super simple to use over the top competitors. Never experienced an issue with these and having a Sub out is a huge advantage. I'm running 2 ceiling speakers and a sub in my office on this amp and if you bring the volume up to the top it says clear all day! Once you pick this amp up you will notice the build quality is fantastic.

Products just need a little better engineering
I own an A/V integration company and have been selling Sonos for decades. Sonos has changed a lot of their policies and now I wanted to switch to MusicCast to sell to my clients. MusicCast does a lot right but really lacks in the area that seems like it would be easy to fix, the music streaming services. It integrates with Pandora but does not allow you to play your playlists and it only integrates with one account. Does not integrate with Tune-In and other internet radio streaming services. Also, need to add a few business music options to open it up for commercial use like Mood Media or Soundtrack just to name a couple. If they can get serious about some of these issues thay can really have a Sonos killer here.

Great product.
Pros: Easy to use app. Interfaces with Yamaha home theater amps. Sounds great. Perfect size. Stays on line, unlike the Sonos I replaced.

Cons: No Amazon Music. The Spotify interface is cumbersome...why can't it control Spotify from the MusicCast app? Product cannot be updated to use Amazon, per Yamaha.

I purchased WXA-50 and WXC-50 to go along with TSR-7810. In particular, the WXA-50 is an impressive small form amp packed with a lot of features. It's hooked up to Polk bookshelf speakers and to my ears sound great.

MusicCast setup was straightforward...taking maybe 5 minutes for each streaming device. The MusicCast app is solid....would be appreciated if they'd add Apple Music as a native streaming option (not just Airplay / Bluetooth). I subscribe to multiple services (Pandora, SiriusXM & Apple Music) and desire the same functionality for all.

All in all - if you already own a Yamaha receiver with musicCast built in...there's no reason not to add devices to create an affordable, flexible and solid performing whole home audio solution.
