Lab.Gruppen D80:4L

The D 80:4L 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 80:4L, 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.
