For those who seek the biggest and best in home cinema, the AVP45 is the definitive hub for uncompromised performance. This is not just an AV processor—it’s the command centre for the most dynamic and flexible home theatre systems imaginable.
Engineered in Cambridge, UK, the AVP45 delivers 16 channels of immersive audio decoding and processing, powered by the same high-performance DAC architecture found in ARCAM’s flagship stereo hi-fi systems. Every detail, every nuance, every cinematic moment is reproduced with breathtaking clarity and precision.
The AVP45 includes balanced audio outputs for all channels, ensuring pristine signal integrity when paired with external amplification. Combine it with the ARCAM PA9 Class G power amplifier for a system that sets the standard for power, control, and musicality.
Flexibility is at the core of the AVP45. With Matrix Channel Assignment, you have complete freedom to configure your system exactly as you envision—whether for movies, gaming, or sport. Dolby Atmos, DTS:X, IMAX Enhanced and AURO-3D processing, and Dirac Live room correction guarantee a truly world-class experience tailored to your space.
And with the same intuitive interface, vibrant 6.5" colour display, and Radia App found across the Radia AV Series, control is effortless—because the experience should be as seamless as the sound.
