Lab Gruppen D 200:4L - 5000W 4-Channel at 4-Ohm 70V/100V Power Amplifier with Lake DSP and Dante Audio Networking in Black Finish

The Lab Gruppen D 200:4L is a high-performance, 5000W, 4-channel power amplifier designed to meet the rigorous demands of large-scale commercial and industrial audio installations. Built on the renowned D Series architecture, this amplifier combines superior audio quality, efficiency, and extensive flexibility, making it ideal for use in stadiums, arenas, convention centers, and other high-demand venues. Engineered with Lab Gruppen's advanced technologies, the D 200:4L offers exceptional output power, low distortion, and seamless integration with digital audio networks, all within a compact and durable 2U rackmount form factor.

At its core, the D 200:4L features Lake DSP (Digital Signal Processing), which provides unparalleled loudspeaker management and system control. This onboard DSP allows for advanced processing capabilities, such as crossovers, EQ, delay, and LimiterMax peak and RMS limiters, ensuring optimal sound quality and system performance in any environment. The amplifier also integrates Rational Power Management (RPM), a proprietary technology from Lab Gruppen that rationalizes power distribution across the four channels, optimizing energy usage and reducing the need for multiple amplifiers in certain configurations. This flexibility is particularly valuable in large-scale installations where system requirements can change over time.

The D 200:4L is equipped with 8x8 channels of dual-redundant Dante digital audio networking with AES67 support, offering seamless integration into modern, networked audio systems. With support for up to 192 kHz sample rates and 24-bit resolution, it provides pristine audio quality and reliable performance, even over long distances. The amplifier's Dante connectivity ensures minimal latency and supports flexible topologies, making it easy to connect to and control multiple audio sources across large, distributed systems. Whether used for voice evacuation, background music, or live sound reinforcement, the D 200:4L excels in mission-critical applications where reliability and quality are paramount.

Offering multiple output options, the D 200:4L delivers up to 5000W per channel at 2Ω, making it capable of driving high-power loudspeakers in both low-impedance and high-impedance (70V/100V) systems. The amplifier also features a highly efficient Class-TD output stage with an Intercooler high-efficiency cooling system, allowing it to maintain optimal performance and minimal heat generation during extended use. The amplifier's flexibility extends to its ability to operate in various impedance modes, including Hi-Z configurations for 70V and 100V applications, and it can be used with speakers in configurations ranging from 2Ω to 16Ω, ensuring compatibility with a wide range of speaker setups.

The D 200:4L is built with energy efficiency in mind, featuring a best-in-class Power Factor Correction (PFC) system that reduces running costs and minimizes environmental impact. Additionally, the amplifier incorporates features such as Breaker Emulation Limiter (BEL) to safeguard against mains breaker tripping, as well as Under-Voltage Limiting (UVL), which ensures continued operation during severe voltage drops. These features, combined with the amplifier's modular design, make it a highly reliable solution for installations that demand consistent performance over time.

Other notable features include redundant audio inputs, load monitoring, and system surveillance, which ensure that the D 200:4L meets the stringent requirements for mass notification and voice alarm systems. The amplifier can be easily monitored and controlled through Lab Gruppen's CAFe software, which provides an intuitive interface for system configuration, commissioning, and ongoing management. It also integrates seamlessly with third-party matrix systems such as MediaMatrix and Q-Sys, allowing for advanced system integration and remote control.

Designed for ease of installation and maintenance, the D 200:4L features a rugged 2U rackmount chassis, complete with rear support brackets and a removable dust filter grille for improved airflow. The amplifier's intuitive front panel interface includes tri-color LED indicators for system and channel status, along with dedicated mute buttons for each channel and a power state indicator. The detachable Neutrik powerCON cable ensures reliable power delivery, and the unit is built to meet international standards with CE, ETL, PSE, RCM, BIS, and CCC certifications.
