The POWERNODE is a high-performance streaming amplifier that brings powerful, detailed sound to your home audio setup. With 100W per channel in stereo, HDMI eARC, and BluOS™ multi-room support, it merges true HiFi playback with modern convenience. Whether for music, movies, or both, it’s built to simplify your system without compromising on sound.  

At its core, the POWERNODE is built with DirectDigital amplification, ensuring ultra-low distortion and high efficiency to drive any speaker with precision and clarity. But POWERNODE is more than just an amplifier: it’s a complete high-resolution audio hub, offering seamless access to local music content, radio services and the most popular music streaming services.

For home entertainment, the POWERNODE takes surround sound to the next level. The new game-changer is the optional third channel, which allows you to go beyond stereo.

POWERFUL, DYNAMIC SOUND

The POWERNODE is driven by Bluesound’s refined DirectDigital amplification platform, delivering 100 watts per channel into 8 ohms with exceptional detail and minimal distortion. Whether driving stereo speakers or expanding to a surround setup, the sound is rich, dynamic, and precise; the ideal foundation for audiophile-grade music or cinematic playback.

 

The advanced closed-loop DirectDigital amplifier provides high precision error correction which keeps the signal clean, while state-of- the-art Gallium Nitride FETs in the output stage enable faster, more efficient switching, reducing noise and enhancing detail retrieval. This results in a powerful yet refined amplifier that delivers exceptional dynamics and clarity.

Designed with modern living in mind, the POWERNODE connects to your TV through HDMI eARC, uniquely supports center channel output, and pairs wirelessly with Bluesound rear speakers and subwoofers.

With dedicated front left, right, and center speaker channels, POWERNODE powers a wired front setup while allowing for a streamlined rear channel solution — either with an additional POWERNODE unit for wired speakers or PULSE speakers for wireless rear channels.
