At Prolight + Sound 2010 Lab.gruppen introduced the PLM 20000Q. The PLM 20000Q Powered Loudspeaker Management combines the four-channel Lab.gruppen amplifier platform with Lake Processing.
When compared to conventional approaches using separate components, the PLM 20000Q affords significant advantages in sonic performance, user functionality, rental inventory utilization, and long-term cost savings.
The PLM 20000Q provides four discrete output channels, each rated at greater than 5000 W into 2.2 – 3.3 ohms (4400 W into 4 ohms).
To achieve this massive output power, Lab.gruppen engineers designed an all-new universal (100 to 265 V) Regulated Switch Mode Power Supply (R.SMPS) with power factor correction to reduce peak current draw.
Output devices in the Class TD output stage allow 194 V peak voltage to the load. And the Power Average Limiter works in tandem with a software-controlled Breaker Emulation Limiter (BEL) to avoid tripping of mains breakers, even with prolonged peak demands.
The PLM 20000Q complements two other systems – the four-channel PLM 10000Q and the two-channel PLM 14000 – in the expanded PLM Series. All three integrate Dante networked audio distribution, Lake drive processing, and load verification with real-time performance monitoring.
Each is housed in a 2U hardware frame and is supplied with a special version of the familiar Lake Controller software application for remote monitoring and control of all functions.
The same Lake Controller-equipped computer can control any combination of PLM Series units, new stand-alone LM 26 Lake Processors, Dolby Lake Processors, and legacy Lake units.
