Frequently asked questions
How does the KA68 differ from the KA28?
The KA68 delivers 8 x 750 W at 4 ohms versus the KA28's 8 x 600 W at 2 ohms, and draws 1200 W versus 800 W, making it suited to 4-ohm loudspeaker systems where the KA28 targets 2-ohm configurations.
What DSP functions are built in?
Onboard DSP includes grouping, equalisation, limiters, signal routing, level adjustment, and loudspeaker presets, controllable via the K-array Connect mobile app or K-framework3 desktop software over Wi-Fi or Ethernet.
What protections does the KA68 include?
Built-in protections cover thermal overload, output short circuit, RMS output current limiting, high-frequency protection, power limiter, and clip limiter.
