Frequently asked questions
Does the Prisma-KPRA02+ require an external power supply?
Yes. The unit operates from a dedicated external AC/DC adapter supplying 24 V DC, which accepts 100 to 240 V AC mains input. The adapter is included with the unit.
Is Dante networking available immediately on purchase?
The Prisma-KPRA02+ is Dante-Ready, supporting up to 8 x 8 Dante channels, but Dante functionality requires a separate license activation before use.
What control options are available?
The unit can be configured and controlled via a dedicated Wi-Fi and Ethernet app and desktop software. This covers DSP functions including grouping, equalisation, limiters, routing, level, and loudspeaker presets.
