LAB GRUPPEN D 40:4L_US1 4000W Amplifier with 4 Flexible Output-Channels, Lake Digital Signal Processing and Digital Audio Networking for Installation Applications (D 40:4L_US1)

LAB GRUPPEN D 40:4L_US1 4000W Amplifier with 4 Flexible Output-Channels, Lake Digital Signal Processing, and Digital Audio Networking for Installation Applications (D 40:4L_US1)

The D 40:4L unites 4000 W of adaptable power with cutting-edge LAKE DSP, DANTE Digital Audio Networking, and Advanced System Integrity Monitoring. Built upon the formidable foundation of our esteemed PLM Series, renowned for reliability and sonic prowess across the most demanding concert tours and extensive installations, the D 40:4L is crafted for digitally networked sound applications in expansive venues like stadiums, arenas, theme parks, and more. This series integrates refined output stage technologies and installation-centric hardware and software features. These innovations optimize amplifier system configuration, reducing initial equipment costs and long-term energy consumption for both integrators and end users.

Rational Power Management (RPM)

At the heart of the D Series stands Rational Power Management (RPM), a LAB GRUPPEN innovation empowering system designers and integrators with unprecedented control over power allocation for optimal performance under diverse load conditions. RPM not only curtails initial equipment expenses but also minimizes rack space requirements. Unlike traditional amplifiers, where over-specification for one channel often results in wasted power across others, RPM allows for dynamic power allocation among the four channels of the D 40:4L. This enables scaling up any channel as needed while efficiently distributing the remaining power to handle less demanding loads elsewhere.

CAFE for Green Credentials

The D 40:4L offers seamless configuration and monitoring through the advanced CAFE (Configuring Amplifiers For the Environment) software suite. Beyond enabling comprehensive system surveillance and RPM feature customization, CAFE introduces the Equipment Specification Predictor (ESP). This innovative tool analyzes system and load requirements to recommend ideal specifications for the D Series units, encompassing model selection, quantity needed, heat generation, channel distribution, and current draw. The outcome ensures precise mains management and accurate specifications for cooling systems and UPS, if necessary.

The Power of LAKE Processing

The D Series LAKE amplifiers offer unparalleled input versatility, powered by exclusive LAKE processing algorithms for outstanding performance. With robust control and load monitoring through the LAKE Controller, seamless integration into Dante digital audio networks, and compatibility with popular networked digital matrix systems via third-party middleware, these models ensure extensive connectivity. Equipped with four comprehensive LAKE Processing modules delivering discrete audio throughput channels, they support analog, AES3 digital, and dual redundant Dante networked digital inputs. Each channel offers individual signal selection and programmable failover to analog for added flexibility. Moreover, the onboard LAKE processor includes advanced group control with Raised Cosine™ MESA EQ™ asymmetric filters, while the LimiterMax™ peak and RMS limiters set industry standards for loudspeaker protection and sonic transparency.
