# Bluesound POWERNODE N331 3 Channel Streaming Amplifier The Bluesound POWERNODE is a high-performance "just add speakers" streaming amplifier that combines 100W per channel DirectDigital amplification, the full BluOS multi-room platform, and a comprehensive connection set into one compact, living room-friendly unit. Whether you're building a two-channel hi-fi system, integrating your TV into a stereo setup, or expanding to wireless surround sound, the POWERNODE handles it all from a single box. A glass touch panel with proximity sensing and five programmable presets keeps everyday control simple, while the THX AAA headphone amplifier on the 6.3mm output gives you personal listening at the highest quality. USB-C, analogue RCA, optical, and the combo 3.5mm Mini-TOSLINK input cover every source type, HDMI eARC connects your TV cleanly in a single cable, and BluOS Bonded Speaker Link enables wireless Dolby Digital surround sound by pairing the POWERNODE with rear Bluesound speakers. Dirac Live room correction is also on board, ready to unlock via a future software update. - **100W x 2 DirectDigital Amplification:** Bluesound's refined DirectDigital platform delivers 100W per channel stereo (8 ohm) with IHF dynamic power of 265W at 4 ohm - and can be configured as 80W x 3 LCR for centre channel use in a home theatre setup. THD+N is just 0.005% with SNR of 102 dBA. - **THX AAA Headphone Amplifier:** A dedicated 6.35mm headphone output powered by THX AAA technology provides audiophile-grade personal listening with exceptional low distortion and linearity - plus Bluetooth headphone output for wireless convenience. - **HDMI eARC and Wireless Surround:** Connect your TV via a single HDMI eARC cable and use BluOS Bonded Speaker Link to wirelessly add Bluesound PULSE FLEX or PULSE M speakers as rear channels for a complete Dolby Digital wireless surround system with no receiver required. - **USB-C and Multi-Input Flexibility:** USB-C PC input, analogue RCA, Toslink optical, and a combo 3.5mm optical/analogue input give you four wired source options — covering turntables, CD players, TVs, and computers alongside the built-in streaming platform. - **Dirac Live Ready:** Room correction via Dirac Live is built into the POWERNODE, available to activate via a future software update. Once enabled, Dirac measures your room acoustics and corrects for standing waves and unwanted distortion for cleaner, more balanced sound from your speakers. - **BluOS Multi-Room Streaming:** Access 23+ streaming services including AirPlay 2, Spotify Connect (including lossless), TIDAL Connect, Qobuz Connect, and Roon Ready, with hi-res playback up to 24-bit/192kHz and DSD256.
