PLM+ Series

The New Flagship Touring Solution

Totally Integrated DSP Platform

Allocate Power Where It's Needed

PLM+ Series

PLM+ Series

PLM+ provides complete integration of the entire platform ecosystem

PLM+ has been designed with total integration at the core of the system, allowing complete control and monitoring of the whole platform ecosystem – including networking, audio I/O, signal processing, amplifiers, power supply and connected mains supply – delivering unique operational benefits and improved system control via Lake Controller, CAFÉ and Third Party Protocol integration.

Building on the TEC Award winning PLM 20000Q and offering all of its unique performance characteristics, flexibility, and raw power, PLM+ delivers twice the processing power, twice the throughput, and a whole host of features designed to deliver real world benefits.


Allocate power where it is needed

RPM Provides ultimate flexibility of power output allocation across channels to match specific load requirements, enabling more efficient use of amplifier inventory


More is More: Power, Performance and Processing

PLM+ offers unprecedented levels of refined performance, double the processing power, and even better overall efficiency – proven, tested and trusted


CAFÉ with ESP: Configuration, control and monitoring

Lab.gruppen’s dedicated integrated software provides comprehensive system surveillance, reducing running costs and minimising environmental impact
