Wireless Streaming Amplifier: The Yamaha WXA-50 is a wireless streaming amplifier that is part of Yamaha's MusicCast multiroom audio eco-system. Start with the MusicCast WXA-50 amplifier and add more MusicCast devices over time (like wireless speakers, AV receivers, and soundbars from Yamaha) for a wireless multiroom audio solution. Up to 32 MusicCast devices and 10 groups can be connected.

Discrete Stereo Amplifier: The Yamaha WXA-50 is equipped with a discrete stereo amplifier with low-impedance drive capability, dynamic power, minimal distortion, and excellent sound quality. The amplifier is stable down to 4Ω.

• 4Ω: 105W x 2Ch (20Hz-20kHz, 0.06% THD)
• 6Ω: 70W x 2Ch (20Hz-20kHz, 0.06% THD
• 8Ω: 55W x 2Ch (20Hz-20kHz, 0.06% THD)

Superior Audio Technology: Yamaha's relentless pursuit of sonic purity is clearly evident in the engineering of their WXA-50 wireless streaming amplifier. 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.

• High Performance DAC: The amplifier circuitry uses the same high-performance ESS Sabre digital-to-analog converter (DAC) found in Yamaha's high-end Yamaha AV receivers.
• Precision Volume Control: A 48-bit digital volume control provides much greater precision and quality than conventional controls.
• Proprietary Power & Ground Architecture: A proprietary power supply ground configuration prevents sound degradation.
• Rigid Chassis: A highly-rigid metal chassis supplies the stability necessary for clear, powerful music reproduction.

Yamaha Proprietary Sound Processing: The WXA-50 wireless streaming amplifier incorporates a variety of Yamaha proprietary sound processing technologies - like Compressed Music Enhancer, Volume-Adaptive EQ, & Advanced Bass Extension. You can also choose to bypass this digital audio processing.

• Compressed Music Enhancer: The Compressed Music Enhancer greatly improves sound reproduction from smartphones or other compressed sources, like MP3 files.
• Volume-Adaptive EQ: Volume-adaptive EQ automatically adjusts the bass/treble balance according to the volume level.
• Advanced Bass Extension: Advanced Bass Extension Processing provides a deeper, richer low-end sound - great for use with compact or in-wall speakers.
• Direct Playback Mode: Direct playback mode allows you to play back high-resolution audio sources just as they are, without any processing.

Advanced Audio Features: The Yamaha WXA-50 offers additional audio adjustments to get the most out of the speaker and your music.

• Ultra Low Jitter PLL: Sets the strength of the jitter removal applied to the audio input being played back, in order to adjust the audio quality. When the level is set high, the jitter removal is more effective, but the sound may cut out on low-speed networks. When the level is set low, the jitter removal is less effective, but the signal is more reliable for lower speed networks.
• 3-Band EQ: The amplifier's 3-band EQ (High/Mid/Low) can be adjusted from -6 to +6dB in 0.5dB steps, so you can tailor the sound to your preference.
• Speaker Type: Optimizes the WXA-50's audio output for the type of speakers you have connected - Compact, Bookshelf, Floorstanding, In-ceiling, or In-Wall.

Volume Levels: The WXA-50 provides a variety of volume level controls, settings, and adjustments.

• Initial Volume: Set the volume level when the power is turned on. You can choose between Off (same as the volume when the unit was turned off), Mute, and -80dB to + 0dB in increments of 0.5dB.
• Max Volume: Set the receiver's maximum volume level. This feature is useful to avoid turning the volume too loud by mistake. You can set the Max Volume from -20dB to 0dB in 5dB steps.
• L/R Balance: Adjust the balance of the volume between the left and right speakers from -12 to +12 in 1 steps.
• Input Trim: Adjust the volume level of each input. This is useful to balance the level of each input to avoid sudden changes in volume when switching between input sources. The range is from -6dB to +6dB in 0.5dB increments.
• Subwoofer Volume: Adjust the volume of the amplifier's subwoofer output independently from the main volume. Adjustable from -6dB to +6dB in 0.5dB steps.

Analog & Digital Inputs: The WXA-50 wireless streaming amplifier is fitted with analog & digital inputs. There is one stereo RCA input for connecting an analog audio source. There is one optical (toslink) digital input for connecting digital audio sources. The optical digital input supports 2ch PCM audio up to 32-bit/192kHz.

USB-A Port: The Yamaha WXA-50 is equipped with a rear-panel USB-A 2.0 port that allows you to enjoy a variety of music files stored on a USB mass storage class memory device, such as a USB thumbdrive or portable digital audio player (not compatible with USB HDDs). Your USB mass storage class device must be formatted in FAT 16 or FAT32. USB portable audio devices that can be charged via USB will be charged when plugged into the AV receiver's USB port (5V/0.5A); even in standby mode. Compatible music files include:

• DSD (2.8MHz/5.6MHz)
• FLAC (up to 192kHz/24-bit)
• AIFF (up to 192kHz/24-bit)
• WAV (up to 192kHz/24-bit)
• ALAC (up to 96kHz/24-bit)
• MP3 (up to 48kHz/320kpbs)
• AAC (up to 48kHz/320kbps)
• WMA (up to 48kHz/320kbps)

Binding-Post Speaker Outputs: The WXA-50 wireless streaming amplifier is fitted with four binding post terminals for connection of a single pair of 4 to 16-ohm speakers. The binding-posts will accept bare wire (up to 10AWG), pin-connectors, spade-lugs, and banana plugs (single or dual).

Aux Output (Fixed): The stereo RCA auxiliary output (fixed) allows you to daisy-chain the WXA-50's audio signal output to another integrated amplifier with volume control.

Subwoofer Output: The WXA-50 is equipped with a mono-RCA subwoofer output for connecting a powered sub (sold separately). The subwoofer output is full-range; you will need to use a powered sub with a built-in low-pass crossover.
