Description
The Bluesound POWERNODE N331 is a powerful all-in-one wireless music streaming amplifier combining high-resolution BluOS streaming, amplification and TV connectivity in one compact component.
The latest POWERNODE delivers 100 watts per channel in stereo or can operate as a three-channel LCR amplifier delivering 80 watts per channel into 8 ohms. This makes it equally suited to a high-quality two-channel music system or a streamlined TV and home entertainment setup.
Built around Bluesound’s BluOS multi-room platform, the POWERNODE provides access to a wide range of music services and internet radio alongside AirPlay 2, Spotify Connect, TIDAL Connect, Qobuz Connect and Roon Readysupport. High-resolution audio playback is supported up to 24-bit/192 kHz, together with DSD256.
For television and home cinema use, HDMI eARC provides simple TV integration, while Dolby Digital support and BluOS wireless speaker integration allow the POWERNODE to become the centre of a compact entertainment system.
Connectivity includes analogue, optical and USB inputs, Gigabit Ethernet, dual-band Wi-Fi, two-way Bluetooth, a dedicated subwoofer output and five-way speaker binding posts. A 6.35 mm headphone output is also provided.
Despite its extensive capabilities, the POWERNODE measures only 220 × 70 × 190 mm (W × H × D) and weighs approximately 1.9 kg, making it easy to accommodate within a modern Hi-Fi or media system.
At Riverside HiFi, we can match the Bluesound POWERNODE with the right loudspeakers, subwoofer and cabling, as well as integrate it into a complete BluOS multi-room, TV or smart-home audio system.
