Arcam intros first Radia Series AV amplifiers and processor

Arcam has announced the first AV products to carry its Radia Series branding. The new range comprises three Audio Video Amplifiers, a 16-channel processor and two power amplifiers. The fleet have made their global debut at ISE 2026.

For the Cambridge-based manufacturer, the move builds on a long history in AV development, from early Nicam tuners to what it describes as the world’s first audiophile AV amplifier in the mid-1990s.

The Radia AV line-up consists of three Audio Video Amplifiers – AVA15, AVA25 and AVA35 – alongside the AVP45 Audio Video Processor. These are complemented by two dedicated power amplifiers, the four-channel PA4 and nine-channel PA9, which are due to follow later in the year.

All share the same industrial design, with black casework, yellow detailing and a centrally mounted 6.5-inch high-resolution colour display. Control and configuration are handled via the Arcam Radia app, which supports system setup, presets and streaming.

Dolby Atmos and DTS:X support comes as standard, with Auro-3D available on the AVA25, AVA35 and AVP45. Connectivity includes HDMI with eARC, Bluetooth 5.4 with Auracast, and network streaming via Apple AirPlay, Google Cast, Spotify Connect, TIDAL Connect and Qobuz Connect. All models handle audio up to 24-bit/192kHz and are Roon Ready.

A key focus of the Radia AV models is room optimisation. The AVA15, AVA25, AVA35 and AVP45 all support Dirac Live Active Room Treatment (ART), alongside Dirac Live Room Correction and Dirac Live Bass Control. ART actively coordinates all speakers in a system, aiming to improve bass management, timing and clarity beyond conventional room correction approaches. For custom installers, this offers greater scope to optimise performance in real-world rooms with complex layouts.

Each AV amplifier targets a different installation requirement. The AVA15 offers nine channels of Class D amplification, and twelve channels of processing, with flexible speaker assignment for additional subwoofers or height channels. The AVA25 offers nine channels of Class AB amplification, with 16 channels of processing, designed for larger rooms or more demanding loudspeakers, with a Zone 2 output for multi-room applications. At the top of the range, the AVA35 employs Arcam’s Class G amplification across nine channels, offering improved efficiency and higher usable power on demand, with 16 channels of processing available, alongside Matrix Channel Assignment and a DAC architecture derived from the company’s stereo products.

For more ambitious systems, the AVP45 processor provides sixteen channels of decoding, including Dolby Atmos, DTS:X, Auro-3D and IMAX Enhanced. Balanced outputs and Matrix Channel Assignment are intended to give installers flexibility when pairing the processor with external amplification, such as Arcam’s own PA9, while Zone 2 output supports multi-room integration.

The accompanying power amplifiers are designed to expand system capability. The PA4 is a four-channel Class D amplifier in a slim 1U chassis, suited to driving height, surround or secondary zone speakers. The PA9 delivers nine channels of Class G amplification, developed to partner the AVP45 and support high-channel-count immersive systems with consistent headroom and low distortion.

The Arcam Radia AVA amplifiers and AVP45 processor will be available from authorised Arcam dealers from Q3 2026, with the PA4 and PA9 power amplifiers scheduled to follow in Q4 2026.
