Product Overview
The PLM 8K44 establishes a new standard in Powered Loudspeaker Management Systems by integrating a 4-in, 4-out configuration with industry-standard Dante Networking. Building upon the renowned Lab Gruppen touring foundation exemplified by the iconic PLM series, the PLM 8K44 introduces a powerful new feature set, including rationalized power allocation between channels for optimized performance. With an extended 4-in, 4-out configuration, twice the processing power via the latest version 6.3 Lake Controller release, and industry-standard Dante networking, the PLM 8K44 delivers unparalleled signal processing and audio management. Its total integration of networking, audio I/O, signal processing, amplifiers, power supply, and mains supply enables complete control and monitoring of the entire platform, offering unique operational benefits.
Lab Gruppen PLM8K44SP Features:
- Rational Power Management (RPM):
- The PLM 8K44 not only delivers exceptional performance but also introduces Rational Power Management (RPM), a Lab Gruppen technology offering unprecedented flexibility in allocating output power to amplifier channels. RPM allows users to tailor each channel's power allocation to specific load conditions, optimizing performance without over-specifying amplifiers or bridging channels. This technology minimizes equipment costs, conserves rack space, and enhances long-term energy efficiency without compromising audio quality. With RPM, users can calculate power demands for various loads through the CAFÉ software and optimize power distribution accordingly, resulting in immediate and long-term savings. It also improves mains management and overall system efficiency, reducing operational costs and providing environmental benefits.
- The Power of Lake Processing:
- The PLM 8K44 integrates Lake Processing algorithms, housing four Lake modules and four discrete audio channels. It supports analog, AES3 digital, and Dante networked digital inputs, with individual channel selection and failover options. Its Lake Processor offers group control with MESA EQ asymmetric filters and LimiterMax peak and RMS limiters for loudspeaker protection. The Lake Controller software enables unified control and monitoring of amplifier status and loudspeaker loads, optimized for wireless tablet PC operation. It seamlessly integrates with third-party sound system measurement and optimization software, providing spectrum measurement and EQ adjustment capabilities simultaneously. Additionally, Lake Processing offers classical and linear-phase crossovers for precise control over system response.
- CAFÉ for Green Credentials
- CAFÉ (Configuring Amplifiers For the Environment) is a software suite designed to streamline the configuration and monitoring of the PLM 8K44 amplifier for optimal efficiency. Alongside comprehensive system surveillance and configuration of features like RPM, ISVPL, and Breaker Emulation Limiter (BEL), CAFÉ also provides environmental assistance.
- By integrating with RPM configuration, CAFÉ accurately predicts average mains current draw and generated heat. Leveraging the PLM+ Series' innovative power supply technologies alongside BEL, it ensures mains draw stays within predicted levels. This precision in mains management and thermal control allows for more accurate provision of mains distribution, cabling, and cooling, reducing lifetime running costs and environmental impact while easing demands on UPS systems.
- Allocate Power Where it is Needed:
- RPM offers unparalleled flexibility in allocating power output across channels to meet specific load demands, optimizing amplifier utilization.
- More is More: Power, Performance and Processing
- PLM+ delivers unmatched refined performance, doubling processing power while enhancing overall efficiency, backed by proven reliability.
- CAFÉ with ESP: Configuration, Control and Monitoring
- Lab Gruppen's integrated software offers thorough system surveillance, lowering operational expenses and environmental footprint.
