All systems from the K&F pro.RENTAL range are designed for mobile use. Flexible, reliable and with professional fittings. Handles to make handling easier, and feet positioned where they are needed. The black coating is made of polyurea and is, therefore, more resilient than any other paint. Thought out mechanically and designed for long-term use. The pro.RENTAL series is distinguished acoustically by the best sound characteristics at maximum performance. The carefully selected neodymium chassis deliver optimum results and also meet the highest standards. K&F pro.RENTAL - impressive presentation!

All K&F pro.RENTAL systems can be easily combined with the K&F SystemAmps as a drive and control unit. For maximum performance and effective protection. The presets include the parameters for each loudspeaker in order to achieve an optimum result. This guarantees the user consistent and reproducible results of high quality with marked high system performance. All in all - K&F pro.RENTAL are the ideal sound systems for mobile use with unlimited possibilities.


K&F pro.RENTAL SystemAmps

The new generation

The K&F SystemAmps 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 analogue, digital AES3 and redundant Dante network audio inputs which ensure a high degree of fail-safe performance by means of prioritisation (failover). Control is via Ethernet using the proven Lake® Controller software. Powerful features!
