Primare SP 25 Prisma: Multi-channel processor designed for both cinephiles and audiophiles

The Primare SP 25 Prisma AV processor features an 11-channel setup, capable of decoding nearly all surround and ambient sound formats. It includes four HDMI inputs and two outputs, both supporting 4K video, Dolby Vision, and HDR10+. One of the outputs is equipped with an eARC audio return channel. Additionally, the processor offers various analog and digital audio inputs, including a USB-B port for computer connectivity. This model incorporates a proprietary network platform that operates through Ethernet or Wi-Fi, enabling playback of high-resolution audio files with specifications up to 24 bit / 192 kHz and DSD 128. Music streaming is facilitated through UPnP, Chromecast, Airplay2, and Spotify technologies. Furthermore, the Primare SP 25 Prisma includes a USB-A port for connecting external drives containing popular audio file formats, and it allows mobile device connections via Bluetooth.

The device utilizes printed circuit boards, with a focus on minimizing the length of signal paths during its development. The DAC in the Primare SP 25 Prisma is constructed using two 8-channel ES9026PRO microchips, which deliver 32-bit precision in signal processing and feature an exclusive jitter reduction circuit. All components in the AV processor are rigorously selected to meet specific performance criteria. Additionally, the power supply unit is designed with a toroidal transformer and includes separate voltage stabilizers for both the digital and analog sections.

The processor can be managed through the supplied universal remote control SP25 Prisma or via the dedicated mobile application. Dirac Live auto-calibration is available to optimize the audio system's sound based on the listening environment.

The Primare SP 25 Prisma is engineered to create audio systems that cater to the preferences of both seasoned audiophiles and enthusiasts of contemporary home theater setups. Its design features a sleek, minimalist aesthetic characterized by a robust aluminum front panel, which houses a display and a streamlined array of controls. Consistent with the brand's reputation, the construction quality and finish of the Primare SP 25 Prisma are exemplary, reflecting the highest standards typical of the company's offerings.
