Superior Audio Technology
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.
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 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.
Pro-Grade Connectivity and Control
The WXC-50 supports professional-grade features including:
・Wired Ethernet port
・Wireless off switch
・Optical and analog inputs
・Digital optical and coax outputs
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.
Low Power Consumption
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.
