One advanced install-dedicated
amplifier platform.Two integrated
DSP and networking choices.
D Series is based on the same foundation of robust, high-power
amplifier technologies as Lab.gruppen’s renowned PLM Series
of Powered Loudspeaker Management systems – 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 D Series, 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.
Tesira® VariantLake Variant
In addition to legendary Lab.gruppen reliability and sonic
excellence, D Series incorporates newly refined output stage
technologies along with installation-targeted hardware and
software features that enable optimized audio system design and
configuration. Together, these new technologies allow systems
integrators to minimize both initial equipment costs and end users’
long-term energy consumption.
The D Series platform is available in two variants. The Lake variants
come with on-board Dante networking as standard, and also offer
options for full integration with leading third-party networking and
control systems via purpose-developed middleware. Meanwhile, the
Tesira® variants integrate seamlessly into Biamp Systems’ AVB-based
networked DSP platform as a dedicated, high-power output object.

RPM & CAFÉ: Optimizing efficiency
with flexible output configurations
Rational Power Management (RPM): True flexibility in power allocation
Lab.gruppen’s D Series provides consultants and integrators with
unprecedented flexibility for specifying amplifier output channels
to meet the varying load conditions within a single complex project.
For the first time, Rational Power Management (RPM) provides
true flexibility in allocating available power across the four output
channels. Each channel may be tailored to meet the requirements
of the connected load, and any power not used for that channel
may be allocated for use on other channels.
In addition, regardless of model, RPM ensures that one or more
channels can supply up to 5000 W of output. This avoids amplifier
“over-specification” on all channels or bridging of adjacent
channels in order to meet minimum demands on one powerhungry load, resulting in loss of channel count.
SUBS
LOW FREQUENCY
DRIVERS
RPM also incorporates features that safeguard the defined power
output of one or more specified channels. Using CAFÉ software, it
is possible to ensure that the full output power will be maintained
regardless of demand of other channels, with the remaining
channels responding to a best-case scenario to deliver defined
power output while maintaining rail voltage and power supply
optimisation.
Rational Power Management results in real-world savings, both
immediate and long-term. In many cases, fewer amplifiers – or
lower cost models – may be specified while still fulfilling all power
requirements. It also allows better mains management, avoiding
over-specification of mains distribution, cooling, and UPS (where
required). Finally, the overall gains in efficiency in larger systems
will minimize current consumption and reduce operation costs – a
“green bonus” for the system owner.

CAFÉ with ESP: Integrated software for efficient project planning and fast system configuration
CAFÉ (Configuring Amplifiers For the Environment) is a dedicated
software application for Windows and OSX that provides tools
for system planning, specification and commissioning. CAFÉ
improves work flow efficiency at every stage of the project, from
initial design through bid tender and final system optimization.
CAFÉ software incorporates an innovative design tool, the
Equipment Specification Predictor (ESP), that assures optimum
specification of D Series units for any complex installation project.
ESP examines the system requirement and then generates
a comprehensive report that includes models numbers and
quantities, heat generation, channel power allocation, and current
draw.
Once the D Series units are implemented into the design,
CAFÉ provides the tools for channel output configuration
and commissioning. During operation, CAFÉ also provides
comprehensive system surveillance for monitoring critical
operating parameters of amplifier channels and connected loads.
