The SP25 Prisma is a multi-channel processor designed for both cinephile and audiophile, composed of carefully considered and crafted features and functionality to provide the best home cinema experience for the greatest number of people.

For the cinephile, the SP25 Prisma includes 4K dynamic HDR switching and eARC, with eleven channels of processing and preamplification supported by a custom linear power supply and tuned output stage to provide exemplary performance, particularly when paired with the award winning A35.8 and A35.2 amplifiers.

For the audiophile, dual eight channel DAC chips allow for a unique digital to analog conversion circuit allocating four channels of conversion when delivering signal to the pair of front left and right analog outputs perfect for bi-amping of the front left and right speakers for improved stereo performance.

For both cinephile and audiophile, Dirac Live® Room Correction utilises state-of-the-art, patented algorithms to analyse and digitally reduce the impact of the room, enhancing the performance of any audio system. Dirac optimises the sound not only with respect to frequency, but also to phase, providing not only linear frequency response but precise arrival time for both two and multi-channel listening with previously unheard detail and clarity.

Individualised control and connectivity is afforded by seventeen customisable input pre-sets for virtually any combination of digital and analog, video and audio input configurations, combined with five customisable speaker setup pre-sets for a variety of speaker and DSP configurations to suit any viewing and listening requirements.

The look and feel of Scandinavia 

We believe that every aspect of our products – the way they look, the satisfying feel of the controls – contributes to the overall experience of living with Primare. As a result, Primare products exude the hallmarks of Scandinavian design – simple, elegant designs, with approachable and easy to understand functionality. An example of this is the idea of being inconspicuous, of not drawing undue attention, which is inherent in the compact physical design of the SP25 Prisma and elimination of unnecessary display and front panel controls.
