General Description
The CB-PLM+ range sets the benchmark for Powered Loudspeaker Management Systems. CBPLM+ combines four channels of amplification with unrivalled signal processing and audio management, allowing complete integration in the devices and offering many unique functions not found in other amplifier and DSP “combined” platforms.
CB-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 processing, amplifiers, power supply and connected mains supply – delivering unique operational benefits and system control for the user via Lake Controller, CAFÉ and Third Party Protocol integration.
Building on the TEC Award winning PLM 20000Q, CB-PLM+ offers 4 x 5000 Watts output power (CB-PLM 20K44), twice the processing power and throughput, and a whole host of additional features and improvements designed to offer real world benefits. CB-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 CB-PLM+ series incorporates road tested and environmentally conscious technologies.
The CB-PLM 20K44 offers 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.
As with previous generations of PLM, the new CB-PLM+ models benefit from the proven package of onboard Lake Processing and Dante™ digital audio networking, plus redundant audio inputs as well as onboard load monitoring to fulfill the requirements of mission-critical live sound applications, where the show must go on, no matter what
