Prisma-KPRA04+
The Prisma-KPRA04+ is a compact amplified matrix platform from K-Array, pairing the Integrated Electronic Brain-Pro (IEB-Pro) processor with a four-channel Class D power amplifier rated at 150 W per channel. It accepts analog and digital inputs, supports Dante-Ready networking, and provides onboard DSP in an aluminium chassis suited to medium fixed installations requiring more output power than the KPRA02+.

The integrated Wi-Fi alongside wired Ethernet control, optical and balanced analog inputs, and Dante networking capability provides flexible connectivity for a variety of system architectures.
Frequently asked questions
How does the Prisma-KPRA04+ differ from the KPRA02+?
The KPRA04+ delivers 150 W per channel at 4 ohm compared to 50 W per channel for the KPRA02+. It also connects to mains via a PowerCon TRUE IN connector rather than an external DC adapter, and includes Wi-Fi IEEE 802.11 b/g/n alongside wired Ethernet.
Is Dante networking enabled out of the box?
The unit is Dante-Ready and supports up to 8 x 8 Dante channels, but a Dante license activation is required before network audio functionality is available.
What output connector type does the KPRA04+ use?
The output connector type for the four amplified channels is not specified in the available technical data. The KPRA02+ variant uses Euroblock connectors; consult the datasheet for the KPRA04+ output connector specification.
