Arcam Radia AVP45 Streaming Dolby Atmos Home Cinema Processor

Ultimate home cinema sound
Engineered to uncompromising standards, the Arcam AVP45 is designed to exceed the highest home cinema expectations. Powered by the same high-performance DAC (Digital to Analogue Converter) architecture found in Arcam’s flagship stereo systems, every nuance of detail is reproduced with breathtaking clarity and precision.

With Arcam’s Matrix Channel Assignment, you have complete freedom to configure your system exactly as you choose — with substantial upgrade potential built in for the future.

Processing for up to 16 channels — true large-scale immersion
For the ultimate in cinematic immersion, the AVP45 offers processing for up to 16 channels. Add external power amplification and you can decode Dolby Atmos and DTS:X soundtracks up to an expansive 9.1.6 configuration — powerful enough for even the most ambitious dedicated cinema rooms.

For optimal performance and seamless synergy, pairing with matching Arcam power amplifiers is highly recommended.

Dirac room correction — precision tailored to your space
Dirac Live Room Correction uses advanced acoustic measurement and correction technology to optimise sound specifically for your room. Using a calibrated microphone and dedicated software, multiple measurements are taken around the listening area and fed back to the processor, creating a fully bespoke acoustic response. (Professional installation is recommended for best results.)

For even greater control, the system can be upgraded with:

Dirac Live Bass Control
Dirac Live Active Room Treatment*
