K-Array Kommander KA28 – 8-Channel DSP Amplifier, 8x600W

Product Overview

The K-Array Kommander KA28 DSP amplifier delivers eight Class D channels rated 600 watts each at 2 ohms in a 2U rack chassis, making it the Kommander platform built for low-impedance, multi-zone commercial installation. Its 2-ohm minimum impedance rating lets integrators parallel multiple K-array passive loudspeakers per channel, an efficient approach for distributed audio across meeting spaces, worship rooms, and training facilities. As an 8-channel install amplifier with onboard parametric EQ, dynamic limiters, routing, and delay, the KA28 removes the external processor from most designs. Built-in Wi-Fi and Ethernet control keep commissioning and ongoing management simple for AV integrators.

Product Description

Like its Kommander siblings, the KA28 is powered by the Integrated Electronic Brain (IEB), a quad-core 1.5 GHz processor running K-array's osKar operating system. The DSP feature set includes channel grouping, a 3-band fully parametric input EQ, 8-band parametric output filters, dynamic limiters, a freely assignable input-to-output routing matrix with level adjustment, and channel delay up to 115 ms for zone time alignment. Eight balanced XLR-F inputs and four PC 4/4-ST-7.62 terminal block speaker outputs keep equipment-rack wiring orderly in permanent installations.

The K-array Connect mobile app reaches the DSP wirelessly over built-in Wi-Fi for quick onsite changes, while K-framework3 software manages design, tuning, and monitoring of many amplifiers over wired Ethernet — useful when the KA28 anchors campus-wide or multi-room deployments. A REST API ties amplifier control into Crestron, Q-SYS, and other room control processors. At 7.4 kg, the stainless steel chassis is the lightest in the 2U Kommander family, easing rack loading in retrofit projects. For higher per-channel power at 4 ohms, consider the Kommander KA68, or view the entire K-array collection at Creation Networks.

Key Features

• 8x600W at 2 Ohms — Eight Class D channels rated for 2-ohm loads let designers parallel multiple loudspeakers per channel in distributed systems.
• Quad-Core IEB Processor — The Integrated Electronic Brain with osKar OS runs all DSP and control functions on a 1.5 GHz quad-core platform.
• Parametric EQ Throughout — A 3-band parametric input EQ and 8-band parametric output filters tune every zone without external processing.
• Flexible Routing Matrix — Any input routes to any output with independent level control, supporting complex multi-zone commercial layouts.
• Channel Delay to 115 ms — Per-channel delay time-aligns distributed speakers and fill zones across larger rooms.
• REST API Integration — An open REST API connects amplifier control to Crestron, Q-SYS, and other third-party AV control systems.
• Wi-Fi and Ethernet Control — The K-array Connect app manages the unit wirelessly while K-framework3 supervises full systems over a wired LAN.
• Complete Protection Suite — Thermal, short-circuit, RMS current, high-frequency, power limiter, and clip limiter protections keep the system safe.
• Lightest 2U Kommander — At 7.4 kg (16.3 lb), the stainless steel chassis suits credenza racks and weight-sensitive retrofit installs.

Frequently Asked Questions

Which K-array speakers work with the KA28?

The KA28's 2-ohm rating is designed for paralleling K-array passive loudspeakers such as multiple Vyper or Kobra elements per channel, plus compatible passive subwoofers. K-array's amp-to-speaker matching table defines supported combinations, and Creation Networks can verify your loading plan.

Why does the 2-ohm rating matter for commercial installs?

Driving 2-ohm loads means each of the eight channels can power several paralleled speakers, reducing amplifier count and rack space in distributed systems across conference rooms, corridors, and multi-zone facilities.

What does rack installation involve?

The KA28 occupies 2U in a standard 19-inch rack at 430 mm deep and only 7.4 kg. powerCON TRUE power with link output chains mains between stacked Kommander amplifiers for cleaner power distribution.

How does it integrate with room control systems?

The REST API supports third-party control processors, and K-array publishes plugins for Q-SYS, Crestron, Crestron Home, Control4, Symetrix, RTI, and Kramer Control, with a Dante licensing program available through Audinate for the electronics line.

What warranty and support are included?

K-array provides a 5-year manufacturer warranty. Creation Networks is an authorized dealer offering commercial AV design guidance before purchase and technical support after installation.

When should I step up to the KA68 or KA208?

Choose the Kommander KA68 for 750W per channel at 4 ohms, or the Kommander KA208 when full-size line arrays demand 2500W per channel.
