Arcam Radia AVP45 16-Channel Surround Sound Processor

The Arcam Radia AVP45 is a sixteen-channel surround sound processor built in Cambridge, United Kingdom. It uses the same DAC architecture found in high-end stereo systems to decode sixteen channels of audio. Each channel has a balanced audio output on the rear panel, which helps keep the signal clean when connecting to external power amplifiers such as the Arcam PA9.

The processor decodes modern formats including Dolby Atmos, DTS:X, IMAX Enhanced, and Auro 3D. Through matrix channel assignment, installers can reallocate channels freely across all sixteen configurations to customize the listening environment for movies, gaming, or sports. Physical room reflections are resolved with integrated Dirac Live room correction, which calibrates the output to your room's specific acoustic characteristics. These features render it a powerful choice for any custom sound system setup.

The Radia AVP45 connects wirelessly via the Arcam Radia App to manage system parameters, internet radio, and podcasts. It supports wireless streaming via Apple AirPlay, Google Cast, Spotify Connect, Tidal Connect, and Qobuz Connect. The chassis front features a large 6.5-inch color display that shows status and metadata clearly from the main listening position, while the included Bluetooth remote control with Snapdragon Sound and Auracast enables continuous out-of-sight control. This unit delivers high-quality audio signal routing for advanced audio-visual solutions.
