KEF KASA 8-240M 8 Channel Network DSP Amplifier

KEF KASA 8-240M 8 Channel Network DSP Amplifier

Stock expected December 2026 - Pre-order now!

Designed for performance, built with precision, KASA Network DSP Amplifiers deliver
exceptional efficiency and outstanding signal purity, enabled by advanced Class D
amplification enhanced by next generation GaN technology. Powered by Music Integrity
Engine (MIE), they drive KEF architectural speakers with absolute accuracy, reproducing
sound that is natural, detailed, and deeply immersive in both indoor and outdoor
environments.

Available in 2-, 4-, or 8-channel configurations with multiple power options, KASA amplifiers allow channels to be operated single ended or bridged into 4- or 8-ohm loads, enabling effortless adaptation from dedicated listening spaces to expansive multi-zone installations.

Advanced GaNtechnology amplification
KASA amplifiers are meticulously engineered for purity and precision, built on a refined Class D platform elevated by advanced GaN technology. This combination delivers exceptional efficiency and impressively low distortion, even at high output levels. GaN technology enables dynamic, tightly controlled power delivery with substantial output capability while reducing unwanted noise to maintain outstanding signal purity. The result is greater clarity and realism across music and movies, supported by highly efficient circuitry housed within a sleek compact chassis.

Music Integrity Engine® (MIE)
Music Integrity Engine (MIE), KEF’s suite of proprietary DSP algorithms, ensures every
component operates in harmony, applying real time optimisation to maintain tonal balance
and clarity at any volume. MIE leverages bespoke processing calibrated for each KEF speaker, dynamically adapting the audio signal to unlock deeper bass extension while preserving detail and transparency across both music and film content, delivering sound that feels natural, richly detailed, and deeply immersive.

State-of-the-art signal path design
KASA amplifiers employ an advanced signal path architecture throughout the entire chain. By combining premium DAC/ADC design featuring AKM Velvet Sound converters with KEF’s Music Integrity Engine (MIE), they maintain signal integrity and preserve clarity and detail from input to output. The result is rich, transparent sound with exceptional accuracy across all listening levels.

Intuitive control and integration
KASA amplifiers offer a browser-based interface delivered through a web page, eliminating the need for dedicated apps or software and making system management simpler and streamlined. In systems without a dedicated control platform, the amplifier can be fully preconfigured through this interface to match user requirements, enabling flexible standalone operation.

From any device connected to the local network, you can configure multi-zone setups, route any source to selected zones, and fine-tune performance with ease. Additionally, DSP volume control also enables precise, independent level adjustments for each zone.

Optimised by Music Integrity Engine (MIE), the built-in KEF speaker profiles incorporate
bespoke signal-processing chains tailored to each KEF architectural speaker, enabling instant, optimisation without manual tuning. Harnessing the full power of MIE, these profiles deliver deeper bass at any listening level while maintaining clean, controlled performance even during more dynamic passages, resulting in a truly high-fidelity experience.

For integrated homes, KASA amplifiers support IP control drivers, ensuring seamless
compatibility with leading smart home platforms for unified and reliable system control.
Firmware and speaker-profile updates are delivered over the network, keeping the system up to date with new features, enhancements, and performance improvements.

Flexible configurations
KASA amplifiers support a wide range of system designs, from two channel setups to expansive multi-zone applications. The series includes models in 2-, 4-, and 8-channel with different power ratings, which can be configured as single ended or bridged for maximum versatility.

For demanding home theater setups, KASA amplifiers may also be paired with a surround
receiver via pre outs to deliver high-performance external amplification, increasing system
power and dynamic capability.

When required, channels may be bridged into a 4- or 8-ohm speaker load, enabling significantly increased power delivery from a single channel while maintaining exceptional stability and long term reliability.

Comprehensive connectivity
To ensure seamless integration, KASA provides multiple input and output options, including
optical, coaxial, and RCA, making it compatible with a wide range of sources and systems.
Whether you’re powering a dedicated home theatre or creating an outdoor entertainment
space, KASA amplifiers offer the flexibility to make it happen without compromise.

Thoughtful construction
KASA amplifiers combine robust engineering with thoughtful details for reliability, seamless
integration, and long term performance. A silent passive cooling system with a vented chassis supports efficient heat dissipation while reducing dust build up. In addition, internal heatsinking and carefully engineered cabinet ventilation keep the KASA amplifiers silently cool under load, ensuring consistent thermal performance even at sustained high output.

Status LEDs provide clear indications for power, signal, zone, and volume, making system
monitoring and troubleshooting effortless. Universal 120 V/240 V power compatibility allows hassle free installation across regions, while compliance with global regulatory standards gives users peace of mind knowing their equipment is safe and reliable. The sleek 2U rack mountable design with an aluminium front panel offers a professional aesthetic that fits seamlessly into equipment racks.
