Rich Musicality + Immersive Sound = Stunning Realism The AVR31 is a high-power, audio/visual receiver that delivers stunning realism for the ultimate home cinema experience. With native 16-channel decoding of immersive audio from Dolby Atmos, DTS:X and Auro-3D, the AVR31 can deliver incredible theatre experiences. The Arcam AVR31 is designed with a passion for music and movies, bringing both to life with high fidelity and dynamics. The AVR31 features an over engineered toroidal transformer for real world power with low noise. The 7 channels of Class G amplification are based upon those in Arcam stereo amplifiers, guaranteeing musicality otherwise not heard from other AV receivers. The performance and musicality can be assured with Dirac Live® room optimisation included, and accessed instantly with integrated streaming using Apple®Airplay2, Google Chromecast®, Bluetooth with aptX®HD, Spotify Connect, Tidal Connect and UPnP with the MusicLife app. Dirac Live® Bass Control is available at an additional cost via the Dirac website: https://www.dirac.com/online-store/arcam-avr31/ Dirac Live® Bass Control aggregates measurement and location data from each subwoofer as well as the main speakers to determine how a system’s bass is distributed throughout the room.
