Product Overview

All-in-One KA Amplifier & Processing Solution

The KA24 is a 4 channel per 500W on 4 Ohm. It has 4 fully independent and configurable channels.

The KA24 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.

All DSP functions are remote controlled via the K-framework software over RS485 (3-pin XLR) or integrated USB connector.
