Lab.gruppen D Series: The Integration Superpower

The Lab.gruppen D Series provides exceptional performance and

expanded ﬂ exibility in audio ampliﬁ cation for challenging systems

integration applications in stadia, arenas, convention centers and other

advanced or demanding installed sound installations.

Extending downwards in power and based on the proven, innovative

and green ampliﬁ er technologies of the ﬂ agship D Series, these D Series

slimline models also include Rational Power Management (RPM™) –

a proprietary Lab.gruppen technology that rationalises power allocation

and potentially reduces ampliﬁ er inventory. The Lake-variant D Series

Lake Processing Technologies

models beneﬁ t from the proven package of onboard Lake Processing

and Dante™ digital audio networking, and also oﬀ er integration

potential with many 3rd party matrix and proprietary DSP systems

via dedicated middleware. Equipment speciﬁ cation, commissioning

(including conﬁ guring RPM and other unique ampliﬁ er technologies)

and on-going control and system monitoring are managed via the

innovative CAFÉ™ software, running on Mac or PC. D Series features

include redundant audio inputs as well as on board surveillance and

load monitoring to fulﬁ ll the requirements of mission critical voice

evacuation compliance.
