ARCAM AVR21: Class AB 7‑channel AV receiver with HDMI 2.1, 16‑channel decoding, Dirac Live and streaming

The ARCAM AVR21 is a high‑power AV receiver built for listeners who want a serious home‑cinema upgrade without sacrificing musical performance in stereo. As part of the HDA range, it draws on ARCAM’s engineering experience to deliver a more refined, dynamic sound than is typical in this category—bringing both movies and music to life.

The AVR21 provides native 16‑channel decoding for immersive formats including Dolby Atmos, DTS:X and Auro‑3D, enabling highly capable multi‑channel systems with impressive realism. Amplification is a key strength: it features 7 channels of high‑power Class AB amplification, based on ARCAM’s stereo amplifier designs to ensure musicality. For real‑world power delivery with low noise, ARCAM uses an over‑engineered toroidal transformer.

For room optimisation, the AVR21 includes Dirac Live room correction—an effective tool for improving focus, tonal balance and integration in your room. For advanced bass management, Dirac Live Bass Control is available via an additional license. Connectivity is fully modern with HDMI 2.1, eARC compatibility and support for current HDR formats. On the streaming side, it includes Apple AirPlay 2, Google Chromecast built‑in, Bluetooth aptX HD, Spotify Connect and TIDAL Connect, plus MQA support and Roon Ready certification.
