Arcam AVA25 Radia Series AV Amplifier
9-Channel Class AB Dolby Atmos & DTS:X Home Cinema Amplifier – Black
The Arcam AVA25 is built for listeners who want real cinematic scale without sacrificing musical detail. Designed and engineered in Cambridge, UK, this Radia Series AV amplifier delivers authoritative power, refined control, and immersive surround sound in a beautifully understated chassis. Whether you’re watching films, gaming, or listening to high-quality music, the AVA25 brings depth, clarity, and impact to every performance.
Powerful Class AB Amplification for True Cinema Sound
With nine channels of Class AB amplification, the AVA25 delivers 100 watts per channel at 8 ohms, ensuring effortless dynamics and clean headroom for medium to large home cinema rooms. Switch to stereo listening and power increases to 125 watts per channel, making it equally convincing for two-channel music sessions. The result is sound that feels controlled, detailed, and emotionally engaging at any volume.
Immersive Surround Formats Without Compromise
The AVA25 supports a wide range of premium surround sound formats, including Dolby Atmos, DTS:X, IMAX Enhanced, and AURO-3D. From simple setups using virtual height channels to fully immersive multi-speaker layouts, it adapts easily to your system and room. This flexibility makes it ideal for both first-time Atmos users and advanced home cinema builds.
Flexible Speaker Configurations as Your System Grows
Thanks to its nine powered channels, the AVA25 supports popular layouts such as 7.1.2 or 5.1.4 Dolby Atmos. You can also configure 5.1.2 while using the remaining channels for bi-amping your front speakers or powering a second zone. As your home cinema evolves, the AVA25 evolves with it.
Processing for Up to 16 Channels
For larger, more ambitious installations, the AVA25 offers processing for up to 16 channels. When paired with external power amplifiers, it can decode surround formats up to 9.1.6, delivering a truly enveloping cinema experience. This makes it a strong foundation for high-end dedicated home theatres.
Dirac Live Room Correction – Tuned to Your Space
Every room sounds different. Dirac Live Room Correction analyses your listening environment and adjusts the amplifier’s output to suit your space precisely. Using multiple measurement points, it creates a tailored sound profile with improved clarity, balance, and bass control. Optional upgrades such as Dirac Live Bass Control and Active Room Treatment are available via licence for even greater precision.
Advanced Streaming and Smart App Control
The Radia App gives you simple access to streaming services such as Amazon Music and Qobuz, along with internet radio and podcasts from around the world. UPnP support allows playback from your local network, while the intuitive interface makes browsing and control easy from both iOS and Android devices.
AirPlay 2, Google Cast & Connect Services
Seamless compatibility with Apple AirPlay 2 and Google Cast ensures effortless streaming from smartphones, tablets, and laptops. The AVA25 also supports Spotify Connect, Tidal Connect, and Qobuz Connect, allowing you to stream directly from each service’s native app for the best possible sound quality.
Bluetooth 5.4 with Auracast
Equipped with Bluetooth 5.4 and Snapdragon Sound, the AVA25 supports high-quality wireless audio with low latency. Auracast compatibility allows audio to be shared with supported headphones and speakers, adding flexibility for private listening or multi-listener setups.
HDMI 2.1a for Movies, TV & Gaming
Seven 8K-ready HDMI inputs and dual HDMI outputs ensure full compatibility with modern TVs and sources. Support for 8K pass-through, HDR10+, Dolby Vision, and eARC delivers pristine picture and sound. Gamers benefit from 4K/120Hz HDR, VRR, and ALLM, ensuring smooth visuals and responsive gameplay.
Designed for Everyday Ease
A Bluetooth remote control means reliable operation without line-of-sight, while the large colour display presents clear status and metadata information from across the room. Setup is straightforward, menus are intuitive, and daily use feels effortless.
Timeless Radia Series Design
Finished in black with a solid aluminium chassis, the AVA25 reflects Arcam’s refined Radia design language. Minimal controls, subtle illumination, and a precision-machined volume dial give it a premium look that blends naturally into both modern and traditional home cinema spaces.
