High-Power Class AB Home Cinema with 16-Channel Immersive Processing
The Arcam AVR21 HDMI 2.1 High Power Class AB AV Receiver combines seven channels of high-current Class AB amplification with sophisticated sixteen-channel surround processing for serious home cinema systems. Drawing on ARCAM's long history of stereo amplifier design, the AVR21 uses an oversized toroidal transformer and audiophile-focused circuitry to deliver the dynamics required for movies while retaining the musical refinement expected from a premium two-channel component.
Dolby Atmos, DTS:X and AURO-3D decoding provide flexible immersive-audio configuration, while Dirac Live Room Correction helps optimize speaker performance for the listening environment. Seven HDMI 2.1 inputs support compatible 8K/60Hz and 4K/120Hz sources, and integrated AirPlay 2, Google Chromecast, Bluetooth aptX HD, Spotify Connect, TIDAL Connect and Roon Ready functionality give the AVR21 extensive options for high-quality music playback.
