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 any channel on the D 40:4L capable of being significantly scaled up, 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 40:4L 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\u003eThe Power of LAKE Processing\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAll 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. In addition, by employing third-party middleware, D Series LAKE versions can be integrated into on other widely used networked digital matrix systems. All 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 (each with exclusive Iso-float ground isolation), four channels of AES3 digital, and eight dual redundant Dante networked digital inputs. Input signals are individually selectable for each channel, with programmable failover to analog. 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e4,000 Watt amplifier with 4 flexible output channels and up to 2,000 Watts channel output\u003c\/li\u003e\n\u003cli\u003eLake digital signal processing for unparalleled loudspeaker management and system control\u003c\/li\u003e\n\u003cli\u003eIntegrated 8x8 channels of dual redundant Dante digital audio networking with AES67 support\u003c\/li\u003e\n\u003cli\u003e4 x 800 Watts into 2 Ohms, 4 x 1,000 Watts into 2.67 Ohms, 4 x 1,000 Watts into 4 Ohms, 4 x 1,000 Watts into 8 Ohms, 4 x 700 Watts into 16 Ohms, 4 x 500 Watts into Hi-Z 25 V, 4 x 1,450 Watts into Hi-Z 70 V, 4 x 2,000 Watts into Hi-Z 100 V\u003c\/li\u003e\n\u003cli\u003eProven and reliable IDEEA Class D Output Stage with direct drive 70 and 100 V constant voltage systems as well as low impedance\u003c\/li\u003e\n\u003cli\u003eRational Power Management (RPM) provides total flexibility to allocate available power across all 4 output channels for most efficient use of system inventory\u003c\/li\u003e\n\u003cli\u003eBest-in-class Power Factor Correction (PFC) and switch mode power supply reduces running costs and minimizes environmental impact\u003c\/li\u003e\n\u003cli\u003eBreaker Emulation Limiter (BEL) with configurable mains current draw threshold and breaker profile to safeguard mains breakers from tripping\u003c\/li\u003e\n\u003cli\u003eConfigurable Auto Power Down and Adaptive Rail Control enables real world lifetime energy savings\u003c\/li\u003e\n\u003cli\u003eUnder-Voltage Limiting (UVL) for continued operation during severe mains supply voltage drops\u003c\/li\u003e\n\u003cli\u003eDedicated on-board surveillance and load monitoring for mass notification applications\u003c\/li\u003e\n\u003cli\u003eRedundant audio inputs and on-board system surveillance for voice alarm systems\u003c\/li\u003e\n\u003cli\u003eCAFE (Configuring Amplifiers For the Environment) software for design, system planning, equipment planning, installation and commissioning\u003c\/li\u003e\n\u003cli\u003eControl and monitoring integration with 3rd-party matrix systems including MediaMatrix and Q-Sys via dedicated interfacing software\u003c\/li\u003e\n\u003cli\u003eDedicated front-panel mute buttons for each amplifier channel with bicolour LED indication\u003c\/li\u003e\n\u003cli\u003e4 \"Lake Class\" analog input channels with Iso-Float ground isolation for reliable audio distribution\u003c\/li\u003e\n\u003cli\u003e4 input channels of AES\/EBU (AES3) digital audio supporting all standard sample rates up to 192 kHz with 24-bit resolution\u003c\/li\u003e\n\u003cli\u003e2 Neutrik etherCON RJ-45 ports provide dual redundant Dante interfaces and remote configuration via Lake Controller and Dante Controller software\u003c\/li\u003e\n\u003cli\u003eBalanced analog and digital audio inputs and amplifier outputs on plug-in Phoenix connectors\u003c\/li\u003e\n\u003cli\u003eDetachable and locking IEC mains cable rated at 250 V \/ 16 A with variety of wall plugs selectable on order\u003c\/li\u003e\n\u003cli\u003eRemovable dust filter grille for increased air circulation and simple maintenance\u003c\/li\u003e\n\u003cli\u003eRugged slimline (1U) rackmount chassis including rear support brackets for ease of installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGeneral \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProcessing \/ Network: Lake \/ Dante\u003c\/li\u003e\n\u003cli\u003eNumber of amplifier channels: 4\u003c\/li\u003e\n\u003cli\u003eTotal burst power all channels (share among channels with RPM): 4000 W\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMax.
