Rich Musicality + Immersive Sound = Stunning Realism

The AVR21 is a High-Power, 8K AV 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 AVR21 can deliver incredible theatre experiences.

The Arcam AVR21 is designed with a passion for music and movies, bringing both to life with high fidelity and dynamics. The AVR21 features an over engineered toroidal transformer for real world power with low noise. The 7 channels of Class AB 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. 

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.
