Lab Gruppen PLM 5K44 5000W Amplifier with 4 Flexible Output-Channels, Lake Digital Signal Processing and Digital Audio Networking for Touring Applications

Building on the best-selling PLM+ Series, the PLM 5K44 offers up to 4 x 1,250 Watts output power, a multitude of processing power, and a host of additional features designed to provide real world benefits – all at a price point that makes owning them more affordable than ever. Features such as: LAKE Digital Signal Processing; Dante Digital Audio Networking; plus a touring technology first – Rational Power Management (RPM), a proprietary innovation that rationalises power allocation between channels for optimised performance. As with previous generations, the PLM 5K44 provides redundant audio inputs and load monitoring, plus the multi-channel performance that adds flexibility across the user’s entire loudspeaker inventory. The PLM 5K44 makes any production lifecycle easier to specify, smoother to run, and more efficient to control and monitor at the system design stage, during the show – and right through to final load out.
