The KA-1000X4 is a high-performance power amplifier with integrated DSP, optimised to drive and maximise the performance of compatible Krix cinema loudspeakers. In bridged mode, it delivers up to 2400 Watts into 4 Ohms per channel pair, making it ideally suited to Krix Infrasonic extension subwoofers, with flexible four-channel operation also available for compatible Krix cinema loudspeakers.

Krix-specific DSP presets are tailored to compatible Krix loudspeakers, optimising amplifier performance, processing and protection for each product. Presets are pre-loaded and can be selected directly from the front panel – with no software or downloads required. With the amplifier and loudspeaker working together as part of the Krix Integrated Solution, every element is configured to help your Krix cinema perform as intended - from subtle detail and dialogue to powerful, dynamic cinematic moments.

The KA-1000X4 features advanced 24-bit, 96kHz digital signal processing, with powerful filtering, equalisation, crossover, delay and limiting capabilities. Balanced analogue and AES/EBU digital inputs provide flexible connection options for premium home cinema systems, while Ethernet connectivity enables system configuration and monitoring.

Housed in a compact 2RU rack-mount chassis, the KA-1000X4 combines high-power bridged amplification, flexible multi-channel operation and sophisticated processing in a single unit. Comprehensive onboard protection helps safe guard the amplifier and connected loudspeakers during demanding playback, giving you the confidence to experience your Krix cinema at its best.
