D Series: Technology Overview
The D Series from Lab.gruppen off ers an unprecedented combination of sustained high output, impeccable sonic performance,
configuration flexibility, and real-world efficiencies for reduced
installation and operating costs. D Series brings the world’s most innovative, capable and proven amplifier technology to virtually any high specification installation project, regardless of preferred DSP platform or specific matrix components.
Proven Lab.gruppen Technologies
Reliability and durability remain the bedrock criteria for any installation amplifier, and in this regard the D Series rigorously maintains Lab.gruppen’s industry-leading reputation. The amplifier output stages are the Lab.gruppen IntelliDrive Energy Effi cient Amplifier (IDEEA). The Class D output stage is highly effi cient, while the inherently bridged
Channel your power - 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
ecific load conditions. RPM technology also enables the integrator to
sp minimize initial equipment costs, reduce rack space requirement and improve long-term energy effi ciency – all without compromising sonic performance.
With conventional installation amplifiers, it is often necessary to “over-specify” amplifiers to meet the maximum power demand on one channel, leaving excess power capacity wasted on the remaining channels. RPM reduces costly excess capacity by allowin
g re-allocation of output power capacity among the four channels. RPM can be configured so that any channel can be significantly scaled up from its average quarter of the total available power. With RPM in the D Series, up to the specified single channel power can be used for
topology allows a multitude of the rated power output per channel for RPM and stable inherent hi-impedance operation. D Series also off ers 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 voltage- and current-clip limiting. None of the limiters introduce slow, 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 (not available on D10 and D20).
power-hungry low-frequency systems while the remaining output power can be allocated as needed for the mid-frequency and high­frequency drivers, or for less demandin
g 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 specified for the different loads in several different ways. RPM then analyses the desired power in relation to load impedance as well as diff erent channel and device constraints. If all desired power levels are within constraints, RPM safeguards the balance and assures that the specified output power will be maintained regardless of demand of on other channels. If a particular zone’s input is being driven beyond the specified power levels, RPM aids in limiting 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 confi gured and monitored using Lab.gruppen’s CAFÉ (Confi guring Amplifi ers For the Environment) software suite. In addition to providing comprehensive system surveillance and confi guration of RPM and other amplifi er features such as ISVPL and Breaker Emulation Limiter (BEL), CAFÉ also includes valuable help to save the environment. In combination with the RPM confi 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 and internal energy storage) 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 over­specifi 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 Specifi c
CAFÉ also features an innovative design aid – the Equipment Specifi cation Predictor (ESP). ESP examines the system SPL and speaker requirements for a given project and aids in transforming that data into circuit and amplifi er channel requirements. On a system

Lake Processing
D Series Lake versions provide extraordinary input flexibility, the legendary power of exclusive Lake processing algorithms, comprehensive control and load monitoring via Lake Controller, and seamless integration into Dante digital audio networks with AES67 support. In addition, by employing third-party middleware, D Series Lake versions can be integrated into on other widely used networked digital matrix systems.
All three D Series Lake models incorporate four full-featured Lake Processing modules, with four discrete channels of audio throughput input to output. Audio signals are selectable from four channels of analog (with Iso-float ground isolation), four channels via AES3 digital inputs and eight dual redundant Dante networked digital inputs. Input signals are individually selectable for each channel, with programmable failover to to a lower prioritized input.
The full-featured, on-board Lake processor includes group control with Raised Cosine MESA EQ asymmetric filters to match the responses of many loudspeaker systems. LimiterMax peak and RMS limiters set the industry standard for loudspeaker protection and sonic transparency.
The included Lake Controller sof tware provides a unified interface for control of Lake functions and for comprehensive monitoring of both amplifier status and connected loudspeaker loads. Optimized for a wireless tablet PC, Lake Controller is easy and intuitive to operate, with the “feel” of real-time analog faders and controls. Lake Controller also features seamless integration with third party, real­time sound system measurement, optimization, and control software packages. Users can measure spectrum and transfer function and adjust system EQ at the same time, using the same user interface.
