Nine Class A/B channels and sixteen-channel processing for an expandable Radia cinema
Arcam AVA25 is a Radia AV amplifier with nine Class A/B power stages, processing up to 16 channels, HDMI 2.1a 8K, Dirac Live, Dolby Atmos, DTS:X, IMAX Enhanced and Auro-3D.
AVA25 brings an Arcam-developed Class A/B power section to the new Radia AV range. It directly drives 7.1.2 or 5.1.4 systems with nine internal amplifiers and can expand the configuration to 16 channels through its pre-outs, keeping streaming, video and room correction within the same component.

Nine Class A/B power stages
The power section uses nine Class A/B channels and, according to the distributor specification, delivers 7x90 W or 9x75 W into 8 ohms. AVA25 therefore targets immersive systems needing nine directly amplified channels while retaining a traditional Arcam topology distinct from the Class G design of AVA35.
Sixteen-channel processing
The processor handles up to 16 channels with Dolby Atmos, Dolby True HD, Atmos Height Virtualisation, DTS:X, DTS HD Master, DTS Virtual:X, IMAX Enhanced and Auro-3D. Front, surround-back and height channels can be reassigned, while 16 RCA pre-outs allow external power amplifiers to expand the system.
HDMI 2.1a and 8K video
Seven HDMI inputs and three outputs include Zone 2 and support HDMI 2.1a with HDCP2.3, eARC, 8K/60 Hz and 4K/120 Hz. HDR10, HDR10+, HDR10+ Gaming, Dolby Vision, HLG, VRR and ALLM also suit gaming and high-frame-rate video sources.
Dirac Live
Dirac Live Room Correction is integrated to measure room response and apply correction filters to the system. The platform can be upgraded with Dirac Live Bass Control and Dirac Live Active Room Treatment, extending subwoofer management and the treatment of loudspeaker-room interaction later.
Radia streaming and interface
Arcam Radia AV Control handles setup, operation, Internet Radio, podcasts and UPnP. Spotify Connect, Tidal Connect, Qobuz Connect, Roon Ready, AirPlay and Google Cast are joined by Bluetooth 5.4 with Snapdragon Sound, AAC, LE Audio and Auracast for wireless reception and transmission.
Control and Zone 2
Three RCA inputs, two coaxial and two optical inputs complete the audio-source section, while the Zone 2 RCA output provides separate distribution. RS232, IR, 12V trigger and Ethernet support custom integration; the 6.5-inch colour display and back-lit Bluetooth remote improve everyday operation.
Dimensions and accessories
Arcam specifies 432 x 170 x 459.1 mm and a net weight of 21.5 kg, so depth uses the manufacturer's precise figure rather than the distributor's rounded 459 mm. The box includes mains lead, rear-panel cowl, remote with batteries, measurement microphone, 5 m USB cable, Quick Start Guide and safety instructions.
