K-Array Prisma KPRA02+ – Dante-Ready Matrix Processing Platform

Product Overview

The K-Array Prisma KPRA02+ matrix processing platform is a compact, Dante-ready audio DSP and amplified matrix built for conference room audio systems, corporate meeting spaces, and distributed commercial installations. Powered by K-Array's Integrated Electronic Brain-Pro (IEB-Pro), it combines a 4x4 analog matrix, four 50 W amplified outputs, and optional 8x8 Dante channel activation in a half-rack-width aluminum chassis. For integrators who need a single processing and amplification hub for low-impedance speaker zones, the KPRA02+ replaces separate DSP, matrix, and amplifier components with one networked device. It is a processing platform, not a loudspeaker, and is designed to drive K-Array passive speakers such as the Vyper line.

Product Description

At the core of the KPRA02+ is the IEB-Pro processing engine, which provides built-in DSP functions including grouping, equalization, limiters, routing, level control, and factory loudspeaker presets tuned for K-Array passive speakers. The unit ships Dante-Ready, meaning an optional Dante license activation expands the platform to 8x8 Dante network audio channels over its dual RJ45 Ethernet ports — a practical path for integrating the processor into larger networked AV systems without replacing hardware.

Physical I/O covers the needs of most small-to-mid commercial rooms: four balanced Euroblock analog inputs (with K-PREAMPS4 module), a 3.5 mm unbalanced stereo AUX input, and a TOSLINK optical input feed the matrix, while four Class D amplified outputs deliver 4x 50 W at 4 ohms through Euroblock connectors. Remote control is handled over Wi-Fi and Ethernet via K-Array's dedicated app and desktop software, and K-Array publishes control plugins for Crestron, AMX, Q-SYS, and Control4, so the KPRA02+ drops into existing room control systems during commercial AV deployment.

At 219 x 46 x 170 mm and 0.7 kg, the aluminum enclosure fits behind displays, in credenzas, or in shallow rack trays — useful where equipment space is limited. Pair it with K-Array Vyper KV102 II line array elements or browse the full K-Array collection at Creation Networks to build a complete installed audio system.

Key Features

• IEB-Pro Processing Engine — The Integrated Electronic Brain-Pro delivers grouping, equalization, limiters, routing, and level control so one device handles all signal processing for the room.
• Dante-Ready Network Audio — An optional Dante license activation adds up to 8x8 Dante channels over the built-in dual RJ45 Ethernet ports for integration into networked AV systems.
• Four Amplified Outputs — The 4-channel Class D amplifier module delivers 4x 50 W at 4 ohms (minimum 4 ohm, 2 ohm PBTL), powering K-Array passive speakers directly without an external amp.
• Flexible Analog and Digital Inputs — Four balanced Euroblock inputs with the K-PREAMPS4 module, a 3.5 mm stereo AUX input, and a TOSLINK optical input cover microphones, program audio, and consumer sources.
• Control System Plugins — Published K-Array plugins for Crestron, AMX, Q-SYS, and Control4 allow the processor to be managed from the room control platforms integrators already use.
• App and Desktop Remote Control — Wi-Fi and Ethernet remote management through K-Array's dedicated app and desktop software simplifies commissioning and day-two adjustments.
• Loudspeaker Presets Included — Factory presets for K-Array passive speakers shorten tuning time and protect drivers in installed systems.
• Compact Aluminum Chassis — At 219 x 46 x 170 mm and 0.7 kg with an external 24 V DC supply, the unit installs in credenzas, behind displays, or in shallow equipment trays.

Typical Applications

• Boardrooms requiring a single DSP, matrix, and amplifier for program audio and conferencing speakers
• Conference rooms and commercial meeting spaces with multiple analog sources and zoned speaker outputs
• Huddle rooms where rack space is unavailable and a compact amplified processor must hide behind the display
• Training rooms and multi-purpose rooms that need routing and level control across speaker zones
• Government spaces standardizing on Crestron, AMX, Q-SYS, or Control4 control integration
• Houses of worship driving distributed K-Array speech-reinforcement speakers in overflow and lobby zones

Technical Specifications

Frequently Asked Questions

Is the K-Array Prisma KPRA02+ a speaker or a processor?
It is a matrix processing platform with built-in amplification — not a loudspeaker. It processes, routes, and amplifies audio signals to drive passive speakers such as the K-Array Vyper line.

Does the KPRA02+ include Dante out of the box?
The unit ships Dante-Ready. Activating a Dante license unlocks up to 8x8 Dante network audio channels over the built-in Ethernet ports; the license is an optional paid activation.

What speakers can the KPRA02+ power directly?
Its four Class D outputs deliver 50 W each at 4 ohms (minimum 4 ohm load, 2 ohm PBTL), and factory presets are included for K-Array passive speakers, making it a direct match for low-impedance installed models like the Vyper KV102 II.

Does it integrate with Crestron, AMX, Q-SYS, or Control4?
Yes. K-Array publishes control plugins for Crestron, AMX, Q-SYS, and Control4, so the KPRA02+ can be operated from the control processor already specified in your AV system design.

How is the unit configured during installation?
Configuration is performed over Wi-Fi or Ethernet using K-Array's dedicated app and desktop software, covering routing, EQ, limiters, grouping, levels, and speaker preset selection.

What warranty and support apply?
K-Array products carry the manufacturer's 5-year warranty policy, and Creation Networks provides pre-sale system design assistance and post-sale support for commercial AV deployments.
