LAB GRUPPEN D 10:4L_US1 1000W Amplifier with 4 Flexible Output-Channels, Lake Digital Signal Processing, and Digital Audio Networking for Installation Applications (D 10:4L)
The D 10:4L is a powerhouse amplifier integrating 1000W of versatile power with cutting-edge LAKE DSP, DANTE Digital Audio Networking, and advanced System Integrity Monitoring. Developed from the robust, high-power amplifier technologies of the renowned PLM Series, it’s proven itself in demanding concert tours and large-scale installations.
Tailored for digitally networked sound applications in vast venues like stadia, arenas, theme parks, and more, the D 10:4L emphasizes reliability, optimal performance, and efficient energy consumption. Updated output stage technologies, installation-focused hardware, and software features optimize amplifier system design, aiming to minimize upfront costs and long-term energy usage.
Central to its platform is Rational Power Management (RPM), a LAB GRUPPEN proprietary tech offering flexibility in output power allocation. It empowers integrators to allocate power across channels as needed, avoiding over-specification while ensuring peak performance. RPM minimizes costly excess capacity, allowing optimal power distribution among channels to meet specific load conditions.
The accompanying CAFE (Configuring Amplifiers For the Environment) software suite facilitates configuration, monitoring, and RPM feature control. ESP (Equipment Specification Predictor), a design aid within CAFE, recommends the model and quantity of D Series units, facilitating accurate mains management, cooling system specification, and UPS when necessary, based on system and load requirements.
D Series LAKE versions boast remarkable input flexibility, exclusive LAKE processing algorithms, comprehensive control, load monitoring via LAKE Controller, and seamless integration into Dante digital audio networks. These models offer four full-featured LAKE Processing modules and versatile audio input options, including analog, AES3 digital, and Dante networked digital inputs.
With its extensive feature set, from ground-isolated analog inputs to powerful LAKE processing with sophisticated filters and industry-standard limiters, the D 10:4L stands as a pinnacle in delivering unparalleled performance and adaptability for the most demanding installations in vast commercial sound systems.
