D Series: Technology Overview The D Series from Lab.gruppen off ers an unprecedented combination of sustained high output, impeccable sonic performance, confi guration fl exibility, and real-world effi ciencies for reduced installation and operating costs. D Series brings the worlds most innovative, capable and proven amplifi er technology to virtually any high specifi cation installation project, regardless of preferred DSP platform or specifi c matrix components. Proven Lab.gruppen TechnologiesReliability and durability remain the bedrock criteria for any installation amplifi er, and in this regard the D Series rigorously maintains Lab.gruppens industry-leading reputation. The amplifi er output stages are the Lab.gruppen IntelliDrive Energy Effi cient Amplifi er (IDEEA). The Class D output stage is highly effi cient, while the inherently bridged 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. 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 specifi c load conditions. RPM technology also enables the integrator to minimize initial equipment costs, reduce rack space requirement and improve long-term energy effi ciency – all without compromising sonic performance. With conventional installation amplifi ers, it is often necessary to over-specify amplifi 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 confi gured so that any channel can be signifi cantly scaled up from its average quarter of the total available power. With RPM in the D Series, up to the specifi ed single channel power can be used for power-hungry low-frequency 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 specifi ed for the diff erent loads in several diff erent 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 specifi ed output power will be maintained regardless of demand of on other channels. If a particular zones input is being driven beyond the specifi ed 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.

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 over- specifi 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 cation Predictor (ESP)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 level, ESP supplies a recommendation for optimized placement of channels into amplifi ers for the most cost eff ective solution. The recommendation includes model and quantities of D Series required with most rational use of amplifi ers, minimizing wasted headroom. Windows 10 WWW.LABGRUPPEN.COM
