Arcam’s Radia line started as a two-channel flex: clean industrial design, modern streaming, and a display that makes most hi-fi gear look stuck in 2012. Now Arcam is bringing that same Radia identity into home theater with a full stack of AV receivers, a flagship processor, and matching power amps.

The lineup is broad—six products total—but it’s clearly aimed at the enthusiast who’s ready to move past entry-level AVRs and build a “do it right” system. The AVA15, AVA25, and AVA35 are Arcam’s new AV amplifiers (receivers). Above them sits the AVP45, a dedicated AV processor meant for pairing with external amplification. And for power, Arcam is offering two options: the PA4, a compact 4-channel amp meant to expand a system, and the PA9, a nine-channel Class G amplifier designed to be the natural partner for the AVP45.

What makes this Radia AV launch feel like a true flagship play isn’t just the price tags—it’s the feature priority. Arcam is leaning hard into system-wide optimization, and the addition of Dirac across its top models is a very deliberate signal: these are designed for serious rooms, serious speaker layouts, and serious users.

A Familiar Look—And a Display That Actually Matters

It’s worth calling out the design because it’s the first thing you notice. The Radia AV products carry over the same black chassis with yellow accents, and all six models use a high-resolution 6.5-inch color display. In a world where many AV products still rely on tiny segmented text screens (or bury everything in an app), Arcam’s choice to keep a big, readable display front and center is a win—especially for setup, input switching, and day-to-day usability.

And yes: it looks great. The Radia display has the kind of “premium appliance” vibe that makes most AV gear look like industrial lab equipment.

Streaming, HDMI, and the Modern Connectivity Checklist

Across the range, Arcam is checking the boxes people actually use in 2026. You get:

• HDMI with eARC

• Bluetooth 5.4 with Auracast

• Hi-res streaming support including Apple AirPlay, Google Cast, plus Spotify Connect, TIDAL Connect, Qobuz Connect

• Roon support

• 24-bit/192kHz audio handling

• Dolby Atmos and DTS:X across the entire lineup

• Auro-3D on the AVA25, AVA35, and AVP45 (plus the processor also supports IMAX Enhanced)

That’s the broad story: Radia AV is built to be a modern hub, not a “receiver plus adapters plus compromises” situation.

Dirac Is the Real Story Here

Where Radia AV starts separating itself from the crowd is room correction—and not the marketing version.

The AVA15, AVA25, AVA35, and AVP45 support Dirac Live Room Correction, Dirac Live Bass Control, and Dirac Live Active Room Treatment (ART). Dirac ART in particular is the big deal. It’s one of the most advanced approaches to room optimization we’ve seen trickle down into consumer gear, because it goes beyond basic frequency correction. ART is designed to manage how speakers interact with the room and with each other—using the full system to reduce room-induced problems rather than treating each channel like it lives in isolation.

If you’ve ever spent time dialing in a multi-sub setup or taming a problematic room, you already know why this matters. Great speakers can still sound mediocre in a bad room. High-end processors have been chasing this problem for years. Arcam putting ART onto its top Radia models is a strong move—and it positions these as true premium offerings rather than “mid-tier AVRs with a fancy screen.”

(As always: licensing and activation details vary by Dirac feature and region, so the final “what’s included vs optional” breakdown will be something to watch as retail listings go live.)

Breaking Down the Lineup: Who Each Model Is For

Rather than making six products feel like a spec soup, Arcam’s lineup is surprisingly easy to understand:

AVA15: The entry point, but not basic
The AVA15 offers 12 channels of processing, designed for flexible Atmos layouts like 7.1.2 or 5.1.4, with reassignment options for additional height/surround/subwoofer configurations. It’s the model that makes sense for someone building a serious living room theater who wants modern features and Dirac support, but doesn’t need an ultra high-channel-count build.

AVA25: Fewer amp channels, more muscle and features
The AVA25 is a step up for demanding speakers and bigger rooms. It has 9 channels of Class AB amplification (100W per channel) and supports Auro-3D, plus Zone 2 output for multi-room use. Arcam also calls out a toroidal linear power supply, which typically signals better current delivery and stability under real-world load.

AVA35: The flagship AVR
The AVA35 is the top integrated model in the Radia AV lineup. It uses 9 channels of Class G amplification, which Arcam positions as significantly more efficient than traditional Class AB, with better consistency through dynamic swings. It also adds Matrix Channel Assignment, which is basically the kind of flexibility enthusiasts want when they’re mixing internal amp channels with external amps for specific speakers. Arcam also says it includes the company’s higher-performance DAC architecture borrowed from its stereo gear.

AVP45: The “build a real theater” command center
The AVP45 is the dedicated processor—16 channels of decoding, support for Dolby Atmos, DTS:X, IMAX Enhanced, and Auro-3D, plus balanced outputs and flexible channel assignment. It’s designed for users who are already running external amplification or want to go beyond what an all-in-one AVR can comfortably do.

PA4: The practical expansion amp
The PA4 is a 4-channel Class D amp in a slim chassis, aimed at filling gaps—adding height channels, surround back channels, or powering a second zone.

PA9: The flagship power amp partner
The PA9 is a 9-channel Class G amplifier built to pair with the AVP45 and deliver the kind of controlled, efficient power that high-channel-count immersive setups need.

Availability: When You Can Actually Buy It

Arcam debuted the Radia AV lineup at ISE 2026 in Barcelona, but this is not a “buy it tomorrow” launch.

• AVA and AVP models: expected Q3 2026

• PA power amplifiers: expected Q4 2026

Bottom Line

Arcam didn’t just “add a few AVRs.” It built a full Radia home theater platform—receivers, processor, and power amps—wrapped in a premium design language that already works, and anchored by a feature set that clearly targets enthusiasts.

The display is legitimately one of the better-looking implementations in the space, but it’s the Dirac stack—especially ART—that makes Radia AV feel top-tier on paper. Whether these units can translate that promise into real-world performance will come down to implementation, stability, and how well Arcam’s software experience holds up once people start living with these systems.

Still, if you’ve been waiting for Arcam to bring Radia energy into home theater, this is the announcement.
