D Series

K&F D Series SystemAmps

State of the art technology

The K&F system amplifiers are based on the new PLM+ and D series models of the internationally renowned manufacturer, Lab.gruppen. The power amps, which are designed for both live performances and touring, come with special Kling & Freitag module presets, exclusively for K&F loudspeaker systems. The ideal combination!

Impressive power packs

Through ‘Rational Power Management’ (RPM), the overall performance of the power amp can be flexibly distributed over various power amp channels. In addition to the power adapter with power factor correction (PFC), which can be used worldwide, there are analog, digital AES3 and redundant Dante™ network audio inputs which ensure a high degree of fail-safe performance by means of prioritisation (fallback). Control is via Ethernet using the proven Lake® Controller software. With AES67 support an easy interoperability is given for various digital networks.


The integrated Lake Processor is the industry standard for PA system controlling and offers outstanding flexibility in signal processing. Whether it is asymmetrical filters, look-ahead-limiters or automatic input choice – many details make work more efficient while maintaining highest audio quality. The Analyzer Bridge makes it possible to use third party real time analyzers within Lake Control – for a precise system setup.
