The Lab.Gruppen D 20:4L is a state-of-the-art, four-channel amplifier that integrates high-power amplification with advanced Lake Digital Signal Processing and comprehensive digital audio networking, creating a complete system solution for complex installed sound applications. It delivers a robust 2000 watts of power across four highly flexible output channels, which can be independently configured and bridged to meet a wide range of loudspeaker load requirements. The integrated Lake DSP provides extensive processing capabilities, including crossover filtering, parametric EQ, dynamics management, delay, and limiting, all accessible and controllable via intuitive software. This deep integration ensures optimal alignment and protection for each connected loudspeaker, eliminating the need for external processors and simplifying system design, calibration, and control.

A core strength of the D 20:4L is its sophisticated networking architecture, supporting multiple digital audio protocols such as Dante and AES67 for seamless, low-latency audio distribution over standard IP networks. This allows the amplifier to function as a networked audio endpoint, receiving signals directly from a mixing console or digital audio manager without the need for separate analog or AES/EBU cabling. The combination of powerful amplification, precise DSP, and network connectivity makes it an ideal centerpiece for large-scale, distributed audio systems in performing arts centers, houses of worship, stadiums, and other demanding fixed installations where scalability, sound quality, and centralized management are critical.

Built with Lab.Gruppen's renowned reliability, the amplifier features efficient Class-D technology, comprehensive thermal management, and robust protection circuits. Its user interface includes a clear display and navigation controls for local monitoring and adjustment, while full remote control is achieved via network-connected software. The Lab.Gruppen D 20:4L represents a convergence of amplification, processing, and networking, offering system integrators a powerful, streamlined, and future-proof solution that reduces rack space, cabling complexity, and potential points of failure while delivering exceptional audio performance.
