LAB GRUPPEN D 200:4L_US4 20,000W Amplifier with 4 Flexible Output-Channels, Lake Digital Signal Processing and Digital Audio Networking for Installation Applications (D 200:4L_US4)

LAB GRUPPEN D 200:4L_US4 20,000W Amplifier with 4 Flexible Output-Channels, Lake Digital Signal Processing, and Digital Audio Networking for Installation Applications (D 200:4L_US4)

The D 200:4L merges 20,000 W of adaptable power with cutting-edge Lake DSP, DANTE Digital Audio Networking, and advanced System Integrity Monitoring. Drawing from the robust and high-powered foundation of our esteemed PLM Series, the D 200:4L embodies reliability and sonic excellence, proven in the most challenging concert tours and significant installations globally. This amplifier channels these core technologies to cater to the most rigorous digitally networked sound applications. It’s primed for use in expansive venues like stadiums, arenas, theme parks, performing arts centers, racecourses, and large-scale commercial installations. Moreover, the D Series integrates enhanced output stage technologies and installation-focused hardware and software features. These innovations optimize amplifier system design and configuration, enabling integrators to reduce initial equipment costs and drive down long-term energy consumption for end users.

Rational Power Management (RPM)

At the heart of the D Series lies Rational Power Management (RPM), a Lab Gruppen proprietary technology empowering system designers and integrators with unprecedented control over output power allocation for optimized performance in varying load conditions. This innovation allows for smarter use of resources, reducing the need to oversize amplifiers to meet maximum power demands on individual channels, which often results in wasted capacity. With RPM, the D 200:4L enables reallocating power across its four channels, with each channel capable of delivering up to 5000 W, effectively utilizing available power for different load requirements.

CAFE for Green Credentials

The D 200:4L offers seamless configuration and monitoring through the CAFE (Configuring Amplifiers For the Environment) software suite. CAFE not only facilitates in-depth system surveillance and RPM feature configuration but also introduces the Equipment Specification Predictor (ESP). ESP analyzes system and load requirements, providing precise installation recommendations for D Series units, including model and quantity needed, heat generation, channel distribution, and current draw. This comprehensive approach ensures accurate mains management and specific cooling systems or UPS specifications if necessary.

The Power of Lake Processing

The D Series Lake amplifiers offer unparalleled input flexibility, leveraging exclusive Lake processing algorithms for exceptional power and control. With seamless integration into Dante digital audio networks and compatibility with third-party middleware, these amplifiers can easily integrate into widely used digital matrix systems. Featuring four full-featured Lake Processing modules across all models, they support four discrete channels of audio throughput, allowing selection from analog and digital inputs. Each channel offers selectable input signals, failover programming, and a full-featured onboard Lake processor with advanced EQ filters and industry-leading peak and RMS limiters for superior loudspeaker protection and sound clarity.

Rational Power Management

The Rational Power Management (RPM) technology within the D 200:4 amplifier enables an optimal and flexible allocation of its 20,000 W power across its four channels. Each channel can deliver up to 5000 W individually without requiring bridging, preserving the channel count. This allocation method ensures efficient use of the amplifier inventory, allowing the remaining power to be distributed among other channels based on specific demands. This capability ensures the D 200:4 meets the needs of most performance installations without compromise, even in power-demanding applications.

Lake Processing with DANTE

The robust power platform of D Series works hand-in-glove with dual integrated Lake Processing modules. Lake features such as Raised Cosine Equalization™, Limiter Max™ peak and RMS limiters, and Iso-Float™ ground isolation. AES3 digital and dual-redundant Dante networked inputs are standard for compliance in mission-critical PA/VA applications.

Real World Green Credentials

The synergistic blend of innovative power supply technologies, delivering unparalleled low current draw for power output, along with the advanced CAFE software, revolutionizes mains management. This dynamic combination not only enhances overall efficiency but also facilitates significant cost savings on crucial infrastructure elements like cooling and UPS systems. This ultimately reduces both initial installation costs and ongoing operational expenses for venue audio systems.
