• 2000 W or 8000 W in just 2 rack units
• 4 analog IN and 2 AES-EBU IN to 4 fully configurable OUT
• 2 GPIO for external analog controls
• Mic IN and 48V option on all IN for mixer application
• Integrated DSP with processing, matrix and delays
• Onboard touch screen for easy access functions
• K-array loudspeaker presets on-board
• RS485 and USB connectivity for remote control


– The K-array KA line of power amplifiers are comprised of the KA24 and KA84. The KA24 is a 4 channel per 500W on 4 Ohm and the KA84 is a 4 channel per 2000W on 4 Ohm.
– Both have 4 fully-independent and configurable channels. The integrated DSP offers EQ, Matrix, Levels, Delays and Limiter functions on every channel, to avoid the need of external additional processors. The front panel has an easy-to-use touchscreen that gives access to all the basic functions for quick setup and corrections.
– Both models can be used as a mixer for fixed installations thanks to the microphone and Phantom power options available on every analog IN. 2 GPIO ports give easy external analog controls using K-array accessories.
– An onboard library preset with K-array speaker gives an optimal and easy configuration for endless combinations. All DSP functions are remote controlled via the K-framework software over RS485 (3-pin XLR) or integrated USB connector. The amplifier is built into a 2U lightweight, sturdy chassis and comes with a kit of removable rack adapters and four rubber pads for flat surfaces. The KA amplifiers feature optical limiters, and protection against over temperature, over current and short circuits.
– All KA components are designed by the K-array R&D department and custom made under the K-array quality control system.
