Arcam AVP45 16-Channel Dolby Atmos & DTS:X AV Processor – Black
The Arcam AVP45 is built for serious home cinema installations where sound quality and system flexibility matter most. Designed and engineered in Cambridge, UK, this flagship 16-channel AV processor is created to sit at the heart of a high-performance surround system, delivering precise control, clean signal paths and truly immersive audio.
Whether you’re planning a dedicated cinema room or upgrading an existing setup, the AVP45 provides the processing power, format support and connectivity needed for a reference-level experience.
16-Channel Processing with Matrix Channel Assignment
At its core, the AVP45 offers processing for up to 16 channels, supporting configurations up to 9.1.6 when partnered with suitable external power amplifiers. Arcam’s Matrix Channel Assignment gives you the freedom to configure outputs exactly as your room demands, making it easier to design a system that suits your layout rather than forcing you into a fixed template.
Balanced XLR outputs ensure a clean, low-noise connection to high-quality power amplifiers, making this processor an ideal partner for dedicated multi-channel amplification.
Support for Dolby Atmos, DTS:X, IMAX Enhanced & AURO-3D
The AVP45 is compatible with a wide range of immersive surround formats, including:
- Dolby Atmos (including Height Virtualisation)
- DTS:X and DTS Virtual:X
- IMAX Enhanced
- AURO-3D
This broad format support means you can tailor your speaker system from a more compact layout with virtual height channels to a fully specified 3D audio configuration that delivers genuine overhead effects and cinematic scale.
High-Performance DAC Architecture
Drawing on the same advanced DAC design philosophy found in Arcam’s premium stereo components, the AVP45 is engineered to reproduce fine detail with clarity and control. Dialogue remains focused, effects are placed with precision, and dynamic shifts are handled with confidence — whether you’re watching a film, streaming music or gaming.
Dirac Live Room Correction
Every room affects sound differently. The AVP45 includes Dirac Live Room Correction, allowing you to measure and adjust your system to suit your space. Using a calibrated microphone and dedicated software, the processor analyses multiple listening positions and optimises frequency response and timing.
For those looking to go further, optional upgrades such as Dirac Live Bass Control and Dirac Live Active Room Treatment are available via a separate licence.
8K HDMI 2.1a Connectivity for Cinema & Gaming
With seven HDMI inputs supporting 8K pass-through, HDR10+, Dolby Vision and eARC (Zone 1, Output 1), the AVP45 is ready for the latest TVs and source devices. HDMI 2.1a features also benefit gamers, with support for:
- 4K/120Hz HDR pass-through
- VRR (Variable Refresh Rate)
- ALLM (Auto Low Latency Mode)
These features help ensure smoother motion, reduced lag and a responsive gaming experience on compatible displays.
Streaming, AirPlay 2, Google Cast & Connect Services
The AVP45 integrates seamlessly into modern streaming ecosystems. With support for Apple AirPlay 2 and Google Cast, you can stream directly from compatible Apple and Android devices. It also connects with Spotify Connect, TIDAL Connect and Qobuz Connect (subscription required), allowing you to use their native apps for full functionality.
Through the Radia control app, you can access internet radio, podcasts and UPnP playback from devices on your home network, giving you flexible access to music beyond physical media.
Bluetooth 5.4 with Snapdragon Sound & Auracast
Advanced wireless connectivity includes Bluetooth 5.4 with Snapdragon Sound and Auracast compatibility. This enables high-quality wireless streaming from supported smartphones, tablets and computers. Auracast also opens up the possibility of broadcasting audio to compatible headphones and speakers.
Premium Build & Practical Control
As part of Arcam’s Radia Series, the AVP45 features a clean, understated design with an all-aluminium chassis and finely engineered volume control. The large, high-resolution colour display provides clear status and metadata information, while the supplied Bluetooth remote ensures reliable control without needing direct line of sight.
The Command Centre for Reference Home Cinema
More than just a processor, the Arcam AVP45 is designed to be the control hub for a serious multi-channel system. With 16-channel processing, extensive surround format support, Dirac Live calibration and 8K-ready HDMI connectivity, it provides the performance and flexibility required for today’s premium home cinema installations.
If you’re building a no-compromise surround system, the AVP45 delivers the foundation on which the rest of your setup can truly perform.
