K-Array Kommander KA68 – 8-Channel DSP Amplifier, 8x750W

Product Overview

The K-Array Kommander KA68 DSP amplifier is an 8-channel Class D rack-mount unit delivering 750 watts per channel at 4 ohms, engineered for commercial installations that need multi-zone power and onboard processing in a single 2U chassis. Built specifically to drive K-array passive loudspeakers, this 8-channel install amplifier integrates parametric EQ, dynamic limiters, a routing matrix, and channel delay, eliminating the external processor from most system designs. A REST API plus Ethernet and Wi-Fi control make it straightforward to fold into managed AV networks across corporate, government, and worship facilities. At 8.3 kg, the stainless steel chassis suits both space-limited equipment rooms and mobile racks.

Product Description

The KA68 runs on K-array's Integrated Electronic Brain (IEB), a quad-core 1.5 GHz processor with the osKar operating system that hosts the amplifier's full DSP stack: channel grouping, a 3-band fully parametric input EQ, 8-band parametric output filters, dynamic limiters, freely assignable input-to-output routing with level adjustment, and up to 115 ms of channel delay for zone alignment. Eight balanced XLR-F inputs and four PC 4/4-ST-7.62 terminal block outputs handle install wiring cleanly within a standard 19-inch rack footprint.

For commissioning and daily operation, the K-array Connect mobile app reaches the DSP wirelessly over built-in Wi-Fi, while K-framework3 software manages design, tuning, and supervision of multiple amplifiers over wired Ethernet. The REST API opens every key parameter to third-party control processors, which makes the KA68 a strong match for conference room and multi-purpose room AV system integration.

Key Features

• 8x750W Class D Power — Eight channels at 750 watts each into 4 ohms drive distributed loudspeaker zones or compact line arrays from one 2U unit.
• Quad-Core IEB Processor — The Integrated Electronic Brain with osKar OS runs the entire DSP and control stack on a 1.5 GHz quad-core platform.
• Parametric EQ on Every Path — A 3-band parametric input EQ and 8-band parametric output filters tune each zone precisely without outboard gear.
• Assignable Routing Matrix — Any input can feed any output with independent level adjustment, supporting flexible multi-zone commercial designs.
• Channel Delay to 115 ms — Per-channel delay aligns fill speakers and distributed zones across larger rooms.
• REST API Integration — An open REST API exposes amplifier control to Crestron, Q-SYS, and other third-party AV control systems.
• Wireless and Wired Management — The K-array Connect app works over built-in Wi-Fi while K-framework3 manages large systems over Ethernet.
• Comprehensive Protections — Thermal, short-circuit, RMS current, high-frequency, power limiter, and clip limiter safeguards protect amplifier and speakers.
• Compact 8.3 kg Build — The lightweight stainless steel 2U chassis fits space-limited equipment rooms and credenza racks.

Typical Applications

• Conference room
• Boardroom

How It Compares

Frequently Asked Questions

Which K-array speakers does the KA68 drive?

The KA68 is built for K-array passive loudspeakers such as Kobra, Python, Vyper, and compatible passive subwoofers, with matching guidance published in K-array's amp-to-speaker table. Creation Networks can confirm channel loading for your specific room design.

How does the KA68 fit a conference room AV system?

Its eight 750W channels, routing matrix, and per-channel delay let one 2U amplifier power and process multiple zones in boardrooms, training rooms, and divisible meeting spaces, while the REST API ties amplifier control into Crestron, Q-SYS, or similar room control processors.

What are the rack installation requirements?

The KA68 occupies 2U in a standard 19-inch rack, measures 430 mm deep, and weighs 8.3 kg. PowerCON TRUE power with link output simplifies mains distribution when stacking multiple Kommander amplifiers.

Does the KA68 support Dante or networked control?

The KA68 manages control over Ethernet and Wi-Fi, and K-array participates in a Dante licensing program through Audinate for its electronics line, with control plugins available for Q-SYS, Crestron, Control4, Symetrix, RTI, and Kramer. Confirm the audio transport requirements of your design with our team before ordering.

What warranty covers this amplifier?

K-array provides a 5-year manufacturer warranty, and Creation Networks supports every sale with commercial AV system design help and post-installation technical assistance.

When should I choose the KA208 instead?

If your design needs more than 750W per channel — for example, full-size line array hangs or high-output subwoofers — the Kommander KA208 delivers 2500W per channel in the same 2U format.
