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.
