KEF KASA 4-250M Series 4-Channel Network DSP Amplifier

The KEF KASA 4-250M Series Network DSP Amplifier is engineered to deliver precise, high-performance amplification for sophisticated multi-zone audio installations. Its advanced Class D amplification with next-generation GaN FET technology combines high efficiency with exceptionally low distortion and dynamic power, providing clean and detailed sound across a wide range of listening environments.

Designed around KEF’s commitment to high-fidelity performance, the KASA 4-250M incorporates KEF’s Music Integrity Engine (MIE) and premium AKM Velvet Sound DAC/ADC architecture for accurate signal processing and natural, immersive audio reproduction. With four independent channels delivering up to 250W per channel at 4 ohms, the amplifier provides the power and flexibility required for both focused listening zones and larger multi-zone installations.

Its integrated DSP offers extensive control and system optimisation through an intuitive browser-based interface, eliminating the need for dedicated apps or software. Built-in KEF speaker profiles simplify system configuration, while independent DSP volume control and multi-source, multi-zone functionality provide flexible control for complex audio setups.

The KASA 4-250M supports single-ended or bridged operation with 4- or 8-ohm loads, allowing installers to configure the amplifier according to different system requirements. Optical, coaxial, and RCA inputs provide broad source compatibility, while smart-home integration is supported through IP control drivers.

Built for quiet and reliable operation, the amplifier uses silent passive cooling and features a sleek 2U rack-mountable aluminium chassis, with a rack-mount kit included. With its combination of advanced amplification, sophisticated DSP, flexible connectivity, and installation-friendly design, the KASA 4-250M provides a comprehensive solution for high-quality distributed audio systems.
