Prisma-KPR00+ stands out as a powerful digital processing platform with matrix functionality, featuring the Integrated Electronic BrainPro (IEB-Pro) and supporting up to 8x8 Dante channels that can be activated on demand.

Prisma-KPR00+ is controllable via web thanks to the Web App the built-in interface that can be accessed via any browser and gives full control over DSP parameters, network settings and system updates. The K-Connect for smartphone and tablet provide a user friendly interface for remote control of the DSP main parameters and easy configuration of the signal routing. It gives direct access to the Web App for a more advanced programming and it is ideal for a quick configuration.

The K-Control – is the ultimate solution for easy and accessible control of K-array devices. Using out advanced programming tool to customize the interface to any requirements. Ideal for all applications demanding smart and straightforward control of the K-array ecosystem.

It's possible to extend the capabilities of Prisma-KPR00+ with the KPRIN4 and KPROUT4 accessory boards, each offering an additional 4 channels. This expansion allows for a total of up to 8x analog inputs and outputs (GPI - input controls - multi-zones output configurations) providing flexibility for a diverse range of audio applications with nine distinct configuration setups.

K-array PRISMA Matrix Processing Platform

Highlights

Modular Intelligence for Professional Audio Control

Prisma-KPR is an advanced audio matrix designed for high-end professional audio systems. Engineered with a modular architecture, it offers maximum expandability, full configurability, and seamless integration into both fixed installations and large-scale networked audio environments.

Configurable I/O, Dante™ Networking, and Integrated Control

The PRISMA family offers versatile models with I/O options ranging from 0x0 up to 8x8 balanced analog channels, plus 8x8 Dante™ channels supported by an onboard managed switch for seamless network integration. Integrated GPIO ports provide external control and automation capabilities. Four powered versions deliver output powers of 4x50W, 4x150W, 4x300W, or 4x750W.

The Core of Power and Integration

At its core lies the IEB-PRO, powered by OsKar+ — the native K-array operating system — engineered to provide advanced networking capabilities, signal routing, and system control. Paired with a powerful DSP for high-precision signal processing, it ensures optimal performance in demanding audio environments. The platform offers streamlined control and management via an the onboard Web App, along with intuitive access and seamless configuration through K-Connect and K-Control.

Reliable 1U/2U Rack Design for Versatile Audio Installations

Available in 1U and 2U rack-mountable formats, PRISMA features a compact, durable chassis made from high-quality materials to ensure thermal efficiency and structural reliability. Its space-saving design allows seamless integration into AV racks and audio installations, offering maximum versatility for system integrators and installers.
