The Touring Icon
Lab Gruppen PLM+ SERIES
PLM+ is the flagship touring platform from Lab.gruppen, and sets the benchmark for Powered Loudspeaker Management Systems. It combines four channels of amplification with unrivalled signal processing and audio management, allowing complete integration in the devices, and offering many unique functions not found in other amplifier and DSP “combined” platforms. 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 for the user via Lake Controller, CAFÉ and Third Party Protocol integration.
Lab.gruppen Core Technologies
The Solid Foundation
Reliability, durability, sound quality and pure power remain the fundamentals for any touring amplifier, and in this regard PLM+rigorously maintains Lab.gruppen’s industry-leading reputation. The 12K44 and 20K44 amplifiers output stages are the Lab.gruppen patented Class TD® which couples the efficiency of Class D topologies to the sonic purity of Class A/B designs. The 5K44 uses a newly developed Class D technology design with increased efficiency and sustained sonic performance.
Rational Power Management (RPM)
On top of the outstanding performance users have come to expect from a PLM, the 12K44 also features Rational Power Management (RPM), a proprietary Lab Gruppen technology that provides designers and systems techs with unprecedented freedom to allocate the available output power of each amplifier channel for optimum performance with specific load conditions. For the first time, RPM provides true flexibility in allocating available power across the four output channels. Each channel of the PLM 12K44 may be tailored to meet the requirements of the connected load, and any power not used for that channel may be allocated for use on other channels.
CAFÉ for Green Credentials
CAFÉ (Configuring Amplifiers For the Environment) is a software suite that allows the PLM 12K44 to be easily configured and monitored in the most efficient manner possible. In addition to providing comprehensive system surveillance and configuration of RPM and other amplifier features such as ISVPL and Breaker Emulation Limiter (BEL), CAFÉ also includes valuable help to save the environment. In combination with the RPM configuration CAFÉ can accurately predict estimations of average mains current draw and generated heat, and utilizing the PLM+ Series’ innovative power supply technologies in combination with BEL the mains draw can be safeguarded to a predicted level. The end result is precise mains management and thermal control, which allows more accurate (rather than over-specified) provision of mains distribution, cabling and cooling. This technology suite reduces lifetime running costs and minimizes environmental impact. It also reduces demands on UPS systems.
CAFÉ and Equipment Specification Predictor (ESP)
CAFÉ also features an innovative design aid: the Equipment Specification Predictor (ESP). ESP examines the system SPL and speaker requirements for a given project and aids in transforming that data into circuit and amplifier channel requirements. On a system level, CAFÉ supplies a recommendation for optimized placement of channels into amplifiers for the most cost effective solution. The recommendation includes model and quantities of PLM+ Series required with most rational use of amplifiers, minimizing wasted headroom.
Lake Processing
PLM+ devices provide extraordinary input flexibility, the legendary power of exclusive Lake processing algorithms, comprehensive control and load monitoring via Lake Controller, and seamless integration into Dante digital audio networks. All PLM+ models incorporate four full-featured Lake Processing modules, with four discrete channels of audio throughput input to output. Audio signals are selectable from four channels of analog (with Iso- Float ground isolation), four channels via AES3 digital inputs and eight dual redundant Dante networked digital inputs. Input signals are individually selectable for each channel, with programmable failover to a lower prioritized input.
Lake Controller Software
The included Lake Controller software provides a unified interface for control of Lake functions and for comprehensive monitoring of both amplifier status and connected loudspeaker loads. Optimized for a wireless tablet PC, Lake Controller is easy and intuitive to operate, with the “feel” of real-time analog faders and controls. Lake Controller also features seamless integration with third party, real-time sound system measurement, optimization, and control software packages. Users can measure spectrum and transfer function and adjust system EQ at the same time, using the same user interface.
