Arcam Radia AVA25 Streaming Dolby Atmos Home Cinema Amplifier

Powerful Class-AB Amplification for Home Cinema
The Arcam AVA25 is a high-performance immersive AV amplifier engineered to deliver reference-level audio for both cinematic and music applications. As part of Arcam’s Radia Series, this unit combines decades of British hi-fi expertise with modern home theater requirements. Its nine built-in Class-AB amplification channels provide controlled, musical power that’s at home with demanding loudspeakers and larger listening environments. 

Immersive Audio Decoding and Flexible Processing
Designed to create deeply engaging surround sound experiences, the AVA25 supports all major 3D audio formats, including Dolby Atmos, DTS:X, IMAX Enhanced and AURO-3D. With up to 16 channels of processing and reassignable outputs, this amplifier can accommodate complex speaker layouts such as 7.1.4 or multi-subwoofer installations, offering cinematic soundstage precision and three-dimensional realism. 

Advanced Room Correction with Dirac Live
To ensure this immersive performance translates effectively into any listening space, the AVA25 integrates Dirac Live Room Correction as standard. This sophisticated calibration system analyzes room acoustics and speaker placement, then adjusts frequency and timing responses to improve clarity, imaging and tonal balance. Optional upgrades like Dirac Live Bass Control and Active Room Treatment further refine low-frequency performance for challenging environments. 

Future-Ready Connectivity and HDMI Support
Connectivity on the AVA25 matches its ambitious audio capabilities. Featuring multiple HDMI 2.1a inputs and outputs, the unit supports video up to 8K/60 Hz or 4K/120 Hz with HDR formats such as Dolby Vision, HDR10+, and HLG, as well as gaming-friendly features like VRR and ALLM. A dedicated Zone 2 HDMI output adds flexibility for multi-room setups, while eARC support simplifies high-resolution audio integration with modern TVs. 

Streaming, Control and User Experience
The AVA25 also functions as a modern media hub, offering integrated streaming and control options. Wireless and network playback include Apple AirPlay, Google Cast, Spotify Connect, Tidal Connect, Qobuz Connect and Roon Ready compatibility, while Bluetooth 5.4 with Snapdragon Sound and Auracast extends effortless wireless streaming. A large 6.5-inch high-resolution colour display and the Arcam Radia app simplify setup and everyday control, making the AVA25 as intuitive to operate as it is powerful in performance.
