processing and audio management, allowing complete integration in

the devices and offering many unique functions not found in other

PLM+ has been designed with total integration at the core of the

system, allowing complete control and monitoring of the whole

platform ecosystem – including networking, audio I/O, signal

via Lake Controller, CAFÉ and Third Party Protocol integration.

Building on the TEC Award winning PLM 20000Q, PLM+ offers

up to 4 x 5000 Watts output power (PLM 20K44), twice the

processing power and throughput, and a whole host of additional

from the proven package of onboard Lake Processing and Dante™

digital audio networking, plus redundant audio inputs as well as

live sound applications, where the show must go on, no matter what.

The PLM12K44 and 5K44 offer a touring technology first: Rational

Power Management (RPM™), a new proprietary Lab.gruppen

innovation that rationalises power allocation between channels to

optimise performance and potentially minimise amplifier inventory

features and improvements designed to offer real world benefits.

PLM+ makes any production life cycle easier to specify, smoother

to run, more efficient to control and monitor - at the system design

stage, during the show, and right through to final load out. Proven

at all levels of concert touring, the PLM+ series incorporates road

tested and environmentally conscious technologies.
