Lab Gruppen’s D80:4Ta combines 8,000 W of flexible power with unique onboard integration with Biamp Systems' Tesira DSP platform, featuring AVB digital audio and resolute control via Tesira software.

The D80:4Ta is based on the same robust, high-power amplifier technologies as Lab Gruppen’s renowned PLM Series – an amplifier platform with a proven record of reliability and sonic performance on the world’s most grueling concert tours. With the D 80:4Ta, those same core technologies have been updated to provide solutions for the most demanding digitally networked, installed sound applications – in stadia, arenas, theme parks, performing arts centers, racecourses and other large commercial sound installations.

In addition to its reliability and sonic excellence, the D80:4Ta incorporates newly refined outputs stage technologies along with installation-targeted hardware and software features that optimize amplifier system design and configuration. These unique 'Tesira-variant' models feature fully integrated onboard Tesira DSP and AVB connectivity for seamless integration with Biamp Systems' DSP platform. All together, these technologies allow systems integrators to minimize both initial equipment costs and end users’ long-term energy consumption.

Rational Power Management (RPM)
A proprietary Lab.gruppen technology, Rational Power Management (RPM) allows system designers and integrators the freedom to allocate the output power available on each channel for optimum performance with specific load conditions. RPM 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 one channel on the D80:4Ta capable of delivering up to 5,000 W power output, leaving the remaining available power to be allocated to the other channels for less demanding loads.  

CAFE for Green Credentials
The D 80:4T/Ta can be configured and monitored using the 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.

Seamless Integration with Tesira
All 3 power models in the D Series platform are available as Tesira variants for seamless integration into Biamp Systems’ comprehensive networked environment based on AVB protocols. The D80:4Ta functions as a discrete high-power output device in the Tesira environment, with multi-channel audio inputs, control and monitoring all carried over a single Cat-5e/6 network cable. An analog input option is available for analog failover, which may be required in critical PA/VA applications. These are specified as separate model variant - D80:4Ta.

Rational Power Management
RPM allows truly flexible allocation of the 8,000 W of available power across all 4 channels of the D 80:4 to ensure the most efficient and rational use of amplifier inventory. With a single channel capable of up to 5,000 W without bridging (losing channel count), leaving remaining power to be allocated across other channels as required, D 80:4 is capable of meeting the demands of power-hungry performance-installation applications.

Tesira integration with AVB connectivity
Seamless integration into Biamp Systems’ comprehensive networked DSP platform based on AVB protocols. The D Series units function as a discrete high-power output device in the Tesira environment, with multi-channel audio inputs, control and monitoring all carried over a single Cat-5e/6 network cable.

Real world green credentials
The combination of unique power supply technologies providing class-leading and predictable low current draw to power output, and innovative CAFE software enable better mains management and allow substantial savings to be made on critical infrastructure such as cooling and UPS systems, lowering the overall installation and running costs of a venue audio system.
