Lab.gruppen D Series: The Integration Superpower

The Lab.gruppen D Series provides exceptional performance and

expanded exibility in high-power audio amplication for challenging
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 amplier 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 amplier inventory. Equipment specication,

commissioning (including conguring RPM and other unique amplier
technologies) and on-going control and system monitoring are
managed via the innovative CAFÉ™ software, running on Mac or PC.

The dedicated D Series Tesira® variant models integrate seamlessly

with Biamp® Systems’ comprehensive Tesira® DSP platform via AVB.
D Series features include redundant audio inputs as well as on board
surveillance and load monitoring to fulll the requirements of mission-

critical voice evacuation compliance.

D Series: Technology Overview

The D Series from Lab.gruppen offers an unprecedented

combination of sustained high output, impeccable sonic performance,
conguration exibility, and real-world efciencies for reduced
installation and operating costs. D Series brings the world’s most
innovative, capable and proven amplier technology to virtually any
high specication installation project, regardless of preferred DSP
platform or specic matrix components.

Proven Lab.gruppen Technologies

Reliability and durability remain the bedrock criteria for any installation
amplier, and in this regard the D Series rigorously maintains
Lab.gruppen’s industry-leading reputation. The amplier output

stages are the Lab.gruppen patented Class TD® which couples the
efciency of Class D topologies to the sonic purity of Class B designs.

Rational Power Management (RPM)

At the core of the D Series platform is Rational Power Management
(RPM), a proprietary Lab.gruppen technology that gives system

designers and integrators unprecedented freedom to allocate the

output power available on each channel for optimum performance
with specic load conditions. RPM technology also enables the
integrator to minimize initial equipment costs, reduce rack space
requirement and improve long-term energy efciency – all without

compromising sonic performance.

With conventional installation ampliers, it is often necessary to
“over-specify” ampliers to meet the maximum power demand
on one channel, leaving excess power capacity wasted on the
remaining channels. RPM reduces costly excess capacity by allowing
re-allocation of output power capacity among the four channels.
RPM can be congured so that any channel can supply up to 5000 W
regardless of power model. With RPM in the D Series, the maximum
output channel(s) can be used for power-hungry low-frequency

Equipped with the Intercooler cooling system, D Series ampliers
dissipate heat more effectively and eliminate “end of tunnel” output
device over-temperature problems. D Series also offers a full suite
of protection features, including thermal “show-must-go-on” limiting,
short circuit protection, excessive average current limiting, sustained
VHF (very high frequencies) protection, DC protection and voltage­an d curre nt- clip limitin g. None of the lim iter s introduce sl ow, long term
gain changes that can risk altering the balance of a tuned system.
A Breaker Emulation Limiter (BEL) prevents power interruption while
Under-Voltage Limiting (UVL) allows continued operation despite

severe voltage drops.

systems while the remaining output power can be allocated as
needed for the mid-frequency and high-frequency drivers, or for less
demanding zones within a typical large project – such as concessions,
concourses, VIP suites and function rooms within a sports arena

or stadium.

From within the CAFÉ software, RPM allows the desired power
demand to be specied for the different loads in several different
ways. RPM then analyses the desired power in relation to different
channel and device constraints. If all desired power levels are within
constraints, RPM safeguards the balance and assures that the
specied output power will be maintained regardless of demand of
on other channels. If a particular zone’s input is being driven beyond
the spec ied powe r leve ls, RPM aid s in limitin g that zone to make sure
the power is available for other zones. If the desired total power is in
excess of what the power model can deliver, RPM can facilitate that
the limitation is shared equally among the channels.

CAFÉ and RPM for Green Credentials

D Series is congured and monitored using Lab.gruppen’s CAFÉ
(Conguring Ampliers For the Environment) software suite. In
addition to providing comprehensive system surveillance and
conguration of RPM and other amplier features such as ISVPL and
Breaker Emulation Limiter (BEL), CAFÉ also includes valuable help
to save the environment. In combination with the RPM conguration
CAFÉ can accurately predict, based on the true SPL and speaker
requirements of the individual loads for the given project, estimations
of average mains current draw and generated heat in BTU. With
D Series’ innovative power supply technologies (true Power Factor

Correction utilizing Current Draw Modelling) the required mains
draw is already best in class in relation to burst power output, but in
combination with the BEL the mains draw can also be safeguarded

to the predicted level. The end result is precise mains management

and thermal control, which allows more accurate (rather than over­specied) provision of mains distribution, cabling and cooling.
This technology suite not only saves on installation costs, it also

reduces lifetime running costs and minimizes environmental impact.

It also reduces demands on UPS systems in “mission critical” voice
evacuation systems in arenas and stadia.

CAFÉ and Equipment Specification Predictor (ESP)

CAFÉ also features an innovative design aid – the Equipment
Specication Predictor (ESP). ESP examines the system SPL and
speaker requirements for a given project and aids in transforming
that data into circuit and amplier channel requirements. On a system
