Stream wirelessly to your favorite speakers with the dark silver Yamaha WXA-50 MusicCast Wireless Streaming Amplifier. It outputs up to 55W per channel at 8 Ohms and has Wi-Fi, AirPlay, Bluetooth, and DLNA connectivity built-in for a wireless connection to your compatible smart device. Its optical and stereo RCA inputs allow for a wired connection while its USB input will play digitally stored files from a compatible USB drive.
The WXA-50 features a metal body with an aluminum cover and a slim design that fits just about anywhere. Only 2" tall and 8.4" wide, it can be placed horizontally or vertically, allowing it to fit neatly in almost any space.
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 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, A/V receivers, or Hi-Fi gear, providing more connectivity options.
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.
Rack Shelf Friendly
With the feet removed, the WXA-50 is only 1.6" high, allowing it to be placed on a rack shelf within a 1 RU rack space. Two units can be placed side-by-side on a 19" wide shelf.
The 48-bit digital volume control provides precision while the metal chassis is designed to supply the stability necessary for clear, powerful music reproduction.
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 is designed to improve 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 designed to work well with compact or in-wall speakers. Direct Mode allows you to play back high-resolution audio sources just as they are, without any processing.
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 a slim remote offering six presets, so you can quickly access your favorite Internet radio stations even when your smartphone or tablet isn't handy.
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.
