Lab.gruppen D Series: The Integration Superpower

The Lab.gruppen D Series provides exceptional performance and

expanded flexibility in audio amplification 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 amplifier technologies of the flagship 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 amplifier inventory. The Lake-variant D Series

▸ Four-channel amplifiers available in three power models

▸ D 40:4 - 4000 W of total output power (4 x 1000 W nominal)

▸ D 20:4 - 2000 W of total output power (4 x 500 W nominal)

▸ D 10:4 - 1000 W of total output power (4 x 250 W nominal)

▸ Channel your power - Rational Power Management (RPM)

▸ True flexibility in allocating power output across channels to

match requirements, enabling more efficient use of amplifier

inventory

▸ Any channel can be significantly scaled up in power from its

average quarter of the total available power.

▸ Exceptional power density with 4 high power channels in a

sli

mline 1 rack unit form factor

▸ Dedicated on-board surveillance & load monitoring system

▸ Unique power platform

▸ Universal regulated switching power supply with internal energy

storage and best in class power factor correction

▸ Breaker emulation limiter with configurable breaker profile and

current

▸ Efficient IDEEA class D amplifier modules with low impedance

or direct 70 and 100 V drive.

▸ CAFÉ (Configuring Amplifiers For the Environment) Software

incorporating ESP™ (Equipment Specification Predictor) for

design, system and equipment planning,

installation and

commissioning.

models benefit from the proven package of onboard Lake Processing

and Dante™ with AES67 digital audio networking, and also oﬀer

integration potential with many 3rd party matrix and proprietary DSP

systems via dedicated middleware. Equipment specification, commis-

sioning (including configuring RPM and other unique amplifier technolo-

gies) 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 fulfill the requirements of mission critical voice evacu-

ation compliance
