Get An Amplifier Platform With A Proven Record Of Reliability - The Lab Gruppen D 20:4L 2000 Watt Lake Amplifier With 4 Flexible Output Channels

D 20:4L Combines 2000 W of Flexible Power with the Latest LAKE DSP, DANTE Digital Audio Networking and Advanced System Integrity Monitoring.

The D 20:4L is based on the same foundation of robust, high-power amplifier technologies as our renowned PLM Series – an amplifier platform with a proven record of reliability and sonic performance on the world’s most grueling concert tours and in high-profile, large-scale installations.

With the D 20:4L, those same core technologies have been updated and refocused to provide the ultimate solution for the most demanding digitally networked installed sound applications – in stadia, arenas, theme parks, performing arts centers, racecourses and other large commercial sound installations.

In addition to legendary LAB GRUPPEN reliability and sonic excellence, the D Series incorporates newly refined outputs stage technologies along with installation-targeted hardware and software features that optimize amplifier system design and configuration. Together, these new technologies allow systems integrators to minimize both initial equipment costs and end users’ long-term energy consumption.
