Bluetooth® & 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 & 83/8" 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 15/8" 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 & 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.

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 coming in Fall 2016, 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.
