The Lab Gruppen PLM5K44 BP is a high-density, four-channel touring amplifier that delivers exceptional power and advanced system integration for the most demanding professional audio applications. As part of Lab Gruppen's PLM+ series, this amplifier is built around the company's patented TD (Toroidal Output Device) amplifier technology, renowned for its efficiency, linearity, and ability to deliver massive power—up to 5,000 watts per channel—into low-impedance loads with minimal thermal stress. This makes it ideal for driving high-output line arrays, subwoofer clusters, and stage monitors in large-scale concert tours, festivals, and fixed installations where reliability and pristine sound quality are non-negotiable. The "BP" designation indicates it is equipped with Lake Processing, integrating the powerful Lake Controller software for comprehensive DSP management directly within the amplifier.

A defining feature of the PLM5K44 BP is its fully integrated Lake processing suite, which transforms the amplifier into a sophisticated system processor. Users have access to advanced tools including FIR filtering for linear phase response, parametric and graphic EQ, crossover functions, dynamics processing, and extensive system alignment delay. This deep level of onboard processing allows for precise loudspeaker optimization and system tuning without relying on external DSP units, simplifying the signal chain and enhancing system reliability. The amplifier is fully networkable via Dante, allowing for multi-channel digital audio transport, and it is controllable and monitorable via Lab Gruppen's PLM Remote software or Lake Controller over a standard Ethernet connection.

Constructed in a robust 3U chassis designed for touring durability, the PLM5K44 BP incorporates a sophisticated cooling system with a variable-speed fan to maintain optimal operating temperatures quietly. It offers comprehensive input/output connectivity including analog XLR, digital AES/EBU, and Dante networking via optional cards. The amplifier provides extensive monitoring and protection features, offering real-time data on output voltage, current, power, and temperature. By combining Lab Gruppen's high-efficiency amplifier technology with the industry-leading processing power of Lake, the PLM5K44 BP represents a complete, scalable, and intelligent amplification solution for audio professionals who require ultimate control, power, and fidelity in a single, integrated unit.
