Together, these new technologies allow systems integrators to minimize both initial equipment costs and end users’ long-term energy consumption.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRational Power Management (RPM)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt the core of the D Series platform is Rational Power Management (RPM), a proprietary Lab Gruppen technology that allows system designers and integrators unprecedented freedom to allocate the output power available on each channel for optimum performance with specific load conditions. RPM technology also enables the integrator to minimize initial equipment costs and reduce rack space requirement since 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 allowing re-allocation of output power capacity among the four channels - with up to two channels on the D 120:4L capable of delivering up to 5000 W power output, leaving any remaining available power to be allocated to the other channels for less demanding loads.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCAFE for Green Credentials\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe D 120:4T can be configured and monitored using the new CAFE (Configuring Amplifiers For the Environment) software suite. In addition to providing comprehensive system surveillance and configuration of RPM features, CAFE includes an innovative design aid – the Equipment Specification Predictor (ESP) – that provides tools for optimum specification of D Series units. ESP examines the system and load requirements and then supplies recommendations for the installation that include model and quantity of D Series units, heat generated, channel distribution, and current draw. The end result is accurate mains management and precise specification of cooling systems and UPS, when required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRational Power Management\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRPM allows truly flexible allocation of the 12000 W of available power across all 4 channels of the D 120:4 to ensure the most efficient and rational use of amplifier inventory. With up to 2 channels capable of up to 5000 W without bridging (losing channel count), leaving remaining power to be allocated across other channels as required, D 120:4 is capable of meeting the demands of even power-hungry performance install applications\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLake Processing with DANTE\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe robust power platform of D Series works hand-in-glove with dual integrated Lake Processing modules.
