KASA500 Software update tool
KASA500 is a powerful Class-D Dual 250WPC amplifier. This DSP controlled system amplifier is optimized to deliver thunderous bass from KEF Ci subwoofers. With both line and speaker level inputs, and DSP configurable pass-through with optional high pass filters – the KASA500 is versatile and can be deployed in limitless system configurations. To allow for future flexibility KEF engineers may update the KASA500 DSP firmware to optimize performance with additional KEF speakers. The KASA500 Programmer* is a proprietary tool for updating the KASA500 firmware. NOTE: KASA500 software requires a "USB Type A Male to USB Type A Male cable" for connection between your computer and the KASA500.
