Powerful Hub for Demanding Audio Systems
The Arcam Radia SA45 serves as a high-performance all-in-one integrated amplifier that processes both digital and analog sources at the highest level. It was developed to ensure lossless audio reproduction in large rooms as the heart of modern Hi-Fi systems.
Efficient Class G Amplification with Enormous Reserves
The device operates on the Class G principle and delivers an output of 180 watts into 8 ohms and an impressive 300 watts into 4 ohms per channel. This provides sufficient power to drive even complex loudspeaker systems confidently and dynamically.
High-Resolution Streaming and Digital Precision
With support for Hi-Res Audio up to 32 Bit/768 kHz as well as Native DSD1024, the amplifier enables a precise listening experience. Integrated services such as Tidal, Spotify, and Internet radio, as well as technologies like Apple AirPlay, Google Chromecast, and Bluetooth v5.2 (Qualcomm aptX HD), offer almost unlimited streaming possibilities.
Optimal Room Adaptation through Dirac Live
The advanced Dirac Live room correction ensures precise tuning of the system to individual room acoustics. By correcting sound distortions in the living space, exceptional sound quality for music and movies is achieved.
Extensive Interfaces and Convenient Operation
In addition to classic analog inputs, including dedicated phono stages for MM and MC systems, the SA45 features HDMI eARC for connection to TVs. An 8.8-inch color display clearly shows album covers and information, while control is flexible via the device, remote control, or the ARCAM Radia App.
