In detail

About the WXA-70A

Overview

The Yamaha WXA-70A is a compact streaming amplifier for a pair of passive speakers. It brings together Wi-Fi streaming, Bluetooth, TV sound over HDMI eARC and wired analogue, optical and USB sources, and it is a MusicCast device, so it can be controlled with the MusicCast Controller app and grouped with other MusicCast products around the home. Yamaha rates it at 55W + 55W into 8 ohms (20Hz to 20kHz, 0.06% THD, both channels driven).

Inside, Yamaha uses an ESS SABRE ES9039Q2M DAC with its DAC on Pure Ground circuit layout, and YPAO room calibration (including R.S.C. Reflected Sound Control) runs through the supplied microphone. The aluminium enclosure is 220mm wide, and for custom installations it offers Control4 compatibility, Web Setup, an IR input and a 12V trigger output.
