PLM 20000Q Powered Loudspeaker Management System

Categories: ,


[tab title=”Description”]

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. The two-input, four-output PLM
20000Q features a software-controlled bridge mode, allowing one or both
adjacent channel pairs to be coupled for two or three output channels with
a power rating of 9600 W (@ 4 ohms) on the bridged outputs.
