Lab Gruppen D-Series Amplifier

4-Channel Amplifier Series

  • Four Channels
  • Configurable Peak voltage threshold and profile
  • Up to 4 modules of Classic/linear-phase/FIR crossover, EQ, delay, LimiterMax™ – peak and RMS limiters
  • 4 high quality inputs with Iso-Float ground isolation
  • Rational Power Management (RPM)


The D-Series 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 40:4L, 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.
