The D 120:4T/Ta is based on the same foundation of robust, high-power amplifier technologies as our renowned PLM Series-an amplifier platform with a proven record of reliability and sonic performance on the world’s most grueling concert tours and in high-profile, large-scale installations.

With the D 120:4T/Ta, those same core technologies have been updated and refocused to provide the ultimate solution 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 legendary Lab.gruppen reliability and sonic excellence, the D 120:4T/Ta incorporates newly refined outputs stage technologies along with installation-targeted hardware and software features that optimize amplifier system design and configuration. Uniquely, these 'Tesira-variant' models feature fully integrated onboard Tesira DSP and AVB connectivity for seamless integration with Biamp Systems' DSP platform. All together, these new technologies allow systems integrators to minimize both initial equipment costs and end users’ long-term energy consumption.
