About the Lab Gruppen D 80:4T/Ta
The Lab Gruppen D 80:4T/Ta is an 8,000 Watt four-channel amplifier designed for deep integration within the Biamp Tesira DSP matrix environment, functioning as a high-power output device with audio, control and monitoring handled over Integrated Ethernet AVB. Each channel delivers up to 2,000 Watts across loads from 2 Ohms through to Hi-Z 70 V and 100 V, with a maximum channel output of 5,900 Watts via Rational Power Management (RPM). The Class-TD output stage uses a proprietary Intercooler cooling system, while features such as Breaker Emulation Limiter (BEL), Under-Voltage Limiting, Power Factor Correction and dedicated load monitoring support mass notification and voice alarm applications. CAFE software handles system design, planning and commissioning.
Lab Gruppen D 80:4T/Ta — buyer FAQs
What is the Lab Gruppen D 80:4T/Ta and what makes it different from a standard power amplifier?
The Lab Gruppen D 80:4T/Ta is an 8,000 Watt, four-channel amplifier built specifically for deep integration within the Biamp Tesira DSP matrix environment, where it operates as a high-power output device with audio, control and monitoring handled over Ethernet AVB. Unlike a conventional amplifier, its configuration is hosted entirely by the Tesira system, enabling automatic reconfiguration when a unit is swapped out.
Who makes the D 80:4T/Ta and where does it sit within the Lab Gruppen range?
Lab Gruppen is a Swedish manufacturer founded in 1979 in Kungsbacka, focused on professional power amplifiers for touring and installed sound. The D 80:4T/Ta sits within the installed sound side of that range, designed specifically to pair with Biamp Tesira DSP infrastructure rather than operate as a standalone amplifier, making it a specialist choice rather than a general-purpose model.
What output power and load configurations does the D 80:4T/Ta support?
The amplifier delivers 4 x 2,000 Watts into 2 Ohms, 4 Ohms, Hi-Z 70 V and Hi-Z 100 V, and 4 x 1,500 Watts into 8 Ohms, with 4 x 750 Watts available at 16 Ohms. Rational Power Management allows available power to be allocated flexibly across all four channels, with a maximum channel output of up to 5,900 Watts.
Is the D 80:4T/Ta suitable for voice alarm and mass notification systems?
Yes. The D 80:4T/Ta includes dedicated on-board surveillance and load monitoring for mass notification applications, along with redundant audio inputs and system surveillance for voice alarm systems. Breaker Emulation Limiter and Under-Voltage Limiting provide additional resilience during mains supply issues, supporting the reliability requirements typical of life-safety installations.
What should I check when buying a used Lab Gruppen D 80:4T/Ta?
Confirm the unit's Tesira integration is fully functional, as its core value depends on communication with the DSP environment. Check that all four output channels are operational across the expected load impedances, and verify any included software licences or CAFE configuration files. Used listings vary by condition and age, so review each listing carefully. Purchases on 10K Used include a 21-day warranty covering major functional faults; full details are in the buying guide at https://www.10kused.com/used-av-equipment-guide/.
