The Lab Gruppen PLM 5K44 is a high-power, four-channel touring amplifier that integrates substantial output capability with comprehensive Lake digital signal processing and advanced digital audio networking. Delivering a total of 5000 watts, it provides flexible and robust power across four independently configurable channels, each capable of driving demanding low-impedance loads down to 2 ohms or high-impedance constant-voltage lines. This flexibility makes it a versatile core component for powering complex multi-way loudspeaker systems in large-scale live sound, touring, and major fixed installations. The amplifier employs Lab Gruppen's efficient Class-D technology to achieve high power density and thermal management, essential for reliable performance under the heavy loads and continuous operation required by professional touring productions.

The defining feature of the PLM series is the fully integrated Lake DSP processing on every output channel. This provides an extensive, studio-grade toolkit for system optimization and protection directly within the amplifier, eliminating the need for external processors. Each channel has independent, precise control over crossover filters, parametric EQ, dynamics, delay, and sophisticated limiters. Configuration and control are managed via the industry-standard Lake Controller software, allowing for deep system tuning, real-time network monitoring, and remote control from a computer. Furthermore, the amplifier is equipped with digital audio networking capabilities, such as Dante or other network audio protocols, enabling it to receive audio directly from a digital mixing console over a single Ethernet cable, streamlining signal flow and reducing analog conversions.

Built for the extreme demands of the road, the PLM 5K44 is housed in a robust, road-case-ready steel chassis with comprehensive cooling managed by a variable-speed fan system. It includes extensive protection against all common fault conditions. The integration of high-power amplification, top-tier DSP, and digital audio networking in a single rack unit provides system engineers with a powerful, intelligent, and consolidated solution. This consolidation reduces rack space, cabling complexity, and potential points of failure, making the PLM 5K44 a preferred choice for powering and controlling advanced loudspeaker systems on world-class tours and in permanent high-performance installations.
