Its integrated system concept ensures seamless control and monitoring of all connected devices, offering unique operational benefits.
- Rational Power Management (RPM):
- The PLM 12K44 introduces Rational Power Management (RPM), Lab Gruppen's proprietary technology, enhancing designers' and systems techs' ability to optimize amplifier channel output power for specific load conditions. RPM provides unprecedented flexibility by allowing users to tailor each channel's power allocation to meet load requirements, maximizing efficiency. This prevents over-specification of amplifiers or bridging channels to meet demanding loads, ultimately preserving channel count. Additionally, RPM minimizes equipment costs, rack space, and long-term energy consumption without compromising audio quality. It incorporates safeguards to maintain defined power output and offers various calculation methods within the CAFÉ software for efficient power distribution. By enabling more cost-effective amplifier selection and better mains management, RPM yields immediate and long-term savings while enhancing overall system efficiency and reducing operational costs.
- The Power of Lake Processing:
- The PLM 12K44 incorporates exclusive Lake Processing algorithms, featuring four full-featured Lake modules with four discrete channels of audio throughput input to output. It offers selectable audio signals from four analog channels (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 lower prioritized inputs.
- The on-board Lake Processor includes group control with Raised Cosine MESA EQ asymmetric filters to match any loudspeaker system's response. LimiterMax peak and RMS limiters ensure loudspeaker protection and sonic transparency, setting industry standards.
- Included Lake Controller software provides a unified interface for controlling Lake functions and comprehensive monitoring of amplifier status and connected loudspeaker loads. Optimized for wireless tablet PCs, Lake Controller offers intuitive operation resembling real-time analog controls. It seamlessly integrates with third-party sound system measurement, optimization, and control software, allowing users to measure spectrum and transfer function while adjusting system EQ using the same interface.
- Lake Processing features classical crossovers (selectable up to 48 dB per octave) and linear-phase crossovers capable of slopes exceeding 180 dB per octave, providing greater control to limit lobing and off-axis cancellation.
- CAFÉ for Green Credentials
- CAFÉ (Configuring Amplifiers For the Environment) is a software suite designed to streamline the configuration and monitoring of the PLM 12K44 amplifier for optimal efficiency. It offers comprehensive system surveillance and configuration of features such as Rational Power Management (RPM), ISVPL, and Breaker Emulation Limiter (BEL). Additionally, CAFÉ includes tools to promote environmental sustainability.
- When used in conjunction with RPM configuration, CAFÉ accurately predicts average mains current draw and heat generation. By leveraging the PLM+ Series' innovative power supply technologies and BEL, it safeguards mains draw to predicted levels. This precise mains management and thermal control enable more accurate provisioning of mains distribution, cabling, and cooling, reducing lifetime running costs and environmental impact. Moreover, it lessens demands on UPS systems.
- Allocate Power Where It Is Needed:
- RPM offers unparalleled flexibility in allocating power output across channels to meet specific load needs, optimizing amplifier usage efficiency.
