The Kommander-KA04 is a fully featured 4x150W@4Ω class-D amplifier with a high-performing DSP, the Integrated Electronic Brain (IEB) with osKar custom operating system is running on quad-core 1.5 GHz internal processor.


KA04 offers pristine sound and complete control over the connected loudspeakers, either as a stand alone driving unit and in conjunction with other K-array amplifiers in complex and demanding applications. Furthermore the Oscar operative system implements REST API for easy integration with third-party remote control systems.

The dedicated K-array Connect mobile app provides a user friendly interface for remote control of the DSP main parameters and easy configuration of the signal routing.

K-framework3 is the managing and control software dedicated to professionals and operators looking for a powerful tool for loudspeakers system design and tuning of large a number of units over a wired LAN.

Kommander: All-in-one amplifiers and processing solutions

The Kommander series from K-array is a line of powerful, intelligent amplifiers designed to elevate your audio systems. Featuring powerful DSPs and Class D amplifier modules, the Kommander series can adapt to any context and extend your sound like never before.

Different models for every need

The Kommander series offers an array of models in two main categories: the 8x Inputs to 8x Outputs models and the 4x Inputs to 4x Outputs models. Several distinct variants tailored to fit specific audio requirements, allowing you to find the perfect solution for your unique setup. 

Maximum Power, Great Command

With four to eight channels of amplification, each Kommander amplifier can drive any K-array passive product with maximum power. Fully configurable with integrated DSP, the Kommander series allows for comprehensive control over equalization, routing matrix, delay, and more. Say goodbye to signal processors and take complete control of your sound.

osKar Operative System

The Kommander series integration with the next-generation intelligence operative system osKar enables you to manage the entire ecosystem through various control platforms.

With new and advanced features regularly introduced with each release, the Kommander series is future-proofed and includes a USB player and a webstream receiver. Volumes, Signal Routing, as well as Presets are directly manageable through three different types of software and dedicated professional interface.

Integrative Electronic Brain (IEB)

At the heart of the Kommander series is the Integrated Electronic Brain (IEB), powered by the osKar operating system. Driven by micro-electronics, this system features expansive sound processing capabilities, allowing you complete control over the system performance directly from your device. With a dedicated professional interface and mobile app, managing your sound has never been easier.

Dante Activator

To active a Dante license on a K-array device, just connect the unit to Internet and run the Dante Activator function in the Dante Controller.

Dante Ready Activator scans the local Dante network for any Dante Ready eligible products and shows the available options; purchases are immediately applied to the target devices for a smooth, easy experience.

Updated Control Software

Kommander series amplifiers can be remotely controlled by three different types of free software. From the most complete K-framework 3 for Windows and Mac to a more intuitive web app and a simplified mobile app (wi-fi required), managing your system is simple. Gain full control of your sound with APIs and plugins to manage devices via third-party controllers. Furthermore, an LED located on the front of each machine means you can monitor which devices are in communication with your Kommander amplifier at a glance.
