Compact Amplifier for Modern Listening Habits

The Yamaha WXA-70A combines amplification, streaming, and classic connectivity in one compact device. You can stream music, play TV sound, or connect external sources such as CD players, turntables with suitable output, or other audio devices. This creates a tidy Hi-Fi solution without the need for multiple large components.

Yamaha Hi-Fi Expertise in Compact Form

The WXA-70A is based on Yamaha's Hi-Fi expertise and is designed to deliver a mature sound despite its compact design. The Class D amplification drives various speakers with control, clarity, and spatial effect.

ESS SABRE DAC, D.O.P.G. and Precise Signal Processing

The WXA-70A features an ESS SABRE ES9039Q2M DAC working with Yamaha's digital audio technology. The D.O.P.G. (DAC on Pure Ground) design creates a particularly clean environment for sensitive analog audio signals.

Room-Adapted Sound with YPAO

With the included YPAO microphone, the WXA-70A measures room acoustics and automatically adjusts playback. YPAO R.S.C. considers early reflections that can affect stereo imaging and clarity. YPAO Volume is also specified.

TV Sound via HDMI eARC/ARC

The WXA-70A connects to a suitable TV via HDMI eARC/ARC. This allows you to listen to TV shows, movies, and sports through your speakers and control power and volume with a compatible TV remote control. The adjustable Dialogue Level function enhances voices for better understanding without having to increase the overall volume.

Music Streaming with MusicCast and Direct Services

The MusicCast Controller app bundles the control of the WXA-70A and other MusicCast devices. You can select sources, manage playback, adjust settings per room, or connect rooms for shared playback. AirPlay 2, Google Cast, Spotify Connect, TIDAL Connect, Qobuz Connect, Roon Ready, internet radio, and other compatible music, podcast, and audio services are supported.

Connections for TV, Speakers, Subwoofer, and Sources

The WXA-70A offers inputs for HDMI eARC/ARC, optical digital signals, analog sources via RCA, and USB Type-A for music playback or firmware updates. For playback, there are speaker terminals and a subwoofer output. A network port supplements Wi-Fi and Bluetooth if a wired connection is preferred.

Simple App Setup and Clear Operation

Setup is done via the MusicCast Controller app, where network functions and automatic room correction (YPAO) are configured. On the device itself, an input selector, play button, volume control, and an OLED display support direct operation. A remote control is also included.

Prepared for Integration and Smart Home

The WXA-70A is prepared for integrated systems. Control4 compatibility, Web Setup, IR input, and 12V Trigger facilitate integration into professional control systems. Wi-Fi and Bluetooth can be independently deactivated, which can prevent unintended source selection in fixed installations.

Compact, Solid, and Living Room Friendly

The rigid aluminum chassis, vibration-resistant structure, and careful craftsmanship are designed to support sound purity and detail reproduction. The matte anodized surface, precise controls, and gold-plated speaker terminals underscore the high-quality claim. Thanks to its compact dimensions, the WXA-70A can be well integrated into modern living spaces.
