Lab.gruppen D Series: The Integration Superpower

The Lab.gruppen D Series provides exceptional performance and

expanded

systems integration applications in stadia, arenas, convention centers

and other large or particularly demanding installed sound installations.

Based on the proven, road-tested and green amplifier technologies

of Lab.gruppen’s renowned PLM Series, the installation-dedicated

D Series adds Rational Power Management (RPM™) – a new

proprietary Lab.gruppen technology that rationalises power allocation

and potentially reduces amplifier inventory. The Lake-variant

D Series models benefit from the proven package of onboard
