Powered Loudspeaker Management System

  • 12,000 Watt Amplifier with 4 Flexible Output Channels, LAKE Digital Signal Processing and Dante Digital Audio Networking for Touring Applications.
  • The PLM 12K44 Combines a 4-In, 4-Out Configuration with Industry-Standard Dante Networking, Setting the Benchmark for Powered loudspeaker Management Systems.
  • The PLM 12K44 is the natural successor of the proven, road tested, and trusted LAB GRUPPEN touring foundation exemplified by the iconic PLM series, but with an additional new powerful feature set: the ability to rationalize power allocation between channels to optimize performance. Now packaged in an extended 4-in, 4-out configuration together with twice the processing power via the latest version 6.3 LAKE Controller release, plus industry-standard Dante® networking, the PLM 12K44 sets the benchmark for Powered Loudspeaker Management Systems.
  • 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.
  • The PLM 12K44 features the legendary power of exclusive LAKE Processing algorithms, incorporating four full-featured LAKE 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.
  • 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.
  • RPM Provides ultimate flexibility of power output allocation across channels to match specific load requirements, enabling more efficient use of amplifier inventory.
  • PLM+ offers unprecedented levels of refined performance, double the processing power, and even better overall efficiency – proven, tested and trusted.
  • LAB GRUPPEN’s dedicated integrated software provides comprehensive system surveillance, reducing running costs and minimising environmental impact.
