Designed for digitally networked installed sound applications, the Lab.Gruppen D 80:4L is a 2 RU, four-channel 8000W amplifier, well suited for stadiums, arenas, theme parks, performing arts centers, race courses, and other large commercial sound installations. The D-Series amplifier borrows from the flagship PLM Series amplifier platform, which has a proven record of reliability and sonic performance.

In addition to Lab Gruppen’s legendary reliability and sonic excellence, the D Series incorporates newly refined output-stage technologies with installation-targeted hardware and software features that optimize the amplifier’s system design and configuration. Together, these new technologies allow system integrators to minimize both initial equipment costs and end users’ long-term energy consumption.

Benefits
  • 8000W amplifier with 4 flexible output channels and up to 5900W channel output
  • Lake digital signal processing for unparalleled loudspeaker management and system control
  • Integrated 8×8 channels of dual redundant Dante digital audio networking with AES67 support
  • Proven and reliable Class-TD output stage with proprietary Intercooler high-efficiency cooling system
  • Rational Power Management (RPM) provides total flexibility to allocate available power across all 4 output channels
  • Best-in-class Power Factor Correction (PFC) with Current Draw Modelling reduces running costs and minimizes environmental impact
  • Under-Voltage Limiting (UVL) for continued operation during severe mains supply voltage drops
  • Dedicated on-board surveillance and load monitoring for mass notification applications
  • Redundant audio inputs and onboard system surveillance for voice alarm systems
  • CAFE (Configuring Amplifiers For the Environment) software for design, system planning, equipment planning, installation and commissioning
  • Control and monitoring integration with 3rd-party matrix systems including MediaMatrix and Q-Sys via dedicated interfacing software
  • Dedicated front-panel mute buttons for each amplifier channel with bicolor LED indication
  • 4 Lake Class analog input channels with Iso-Float ground isolation for reliable audio distribution
  • 4 input channels of AES/EBU (AES3) digital audio supporting all standard sample rates up to 192 kHz with 24-bit resolution
  • 2 Neutrik etherCON RJ-45 ports provide dual redundant Dante interfaces and remote configuration via Lake Controller and Dante Controller software
  • Balanced analog and digital audio inputs and amplifier outputs on plug-in Phoenix connectors
  • Detachable Neutrik powerCON cable rated at 250V / 32A
  • Removable dust filter grille for increased air circulation and simple maintenance
  • Rugged 2 RU rackmount chassis including rear support brackets for ease of installation

 

 

Rational Power Management
  • At 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 overspecify amplifiers to meet the maximum power demand on one channel, leaving excess power capacity wasted on the remaining channels.
  • Reduces costly excess capacity by allowing reallocation of output power capacity among the four channels—with one channel on the D 80:4L capable of delivering up to 5000 W power output, and leaving any remaining available power to be allocated to the other channels for less demanding loads.
CAFE for Green Credentials
  • The D 80:4L 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, the heat generated, channel distribution inforamtion, and current draw. The end result is accurate mains management and precise specification of cooling systems and UPS when required.

 

 

The Power of Lake Processing
  • All 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 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 (each with exclusive Iso-float ground isolation), four channels of AES3 digital, or eight dual redundant Dante networked digital inputs.
  • Input signals are individually selectable for each channel, with programmable failover to analog. The full-featured onboard 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.
