PLM 20000Q Powered Loudspeaker Management System

The PLM 20000Q Powered Loudspeaker Management system seamlessly

integrates an extraordinarily powerful four-channel amplifier

platform with Lake® Processing, Dante networked signal distribution,

accurate load verification and real-time performance monitoring.

Engineered as a unified system, the PLM 20000Q affords significant

advantages – in sonic performance, user functionality, inventory utilization,

and long-term cost savings – when compared to conventional

approaches using separate components.
