Prestigious Polish project for Lab.gruppen’s PLM15 July 2009
The fountain benefits from a sophisticated lighting, laser and multimedia projection system, while the audio set-up is based around Lab.gruppen PLM Powered Loudspeaker Management Systems (supplied by the manufacturer’s Polish distributor, Music Info) and EAW loudspeaker cabinets.
Thirteen 4-channel, 2-rack space PLM 10000Q systems with Lake Processing on board power the entire EAW PA system, which comprises more than 200 cabinets drawn from eight different EAW and EAW Commercial ranges.
“This is a big system spread over a large area, much of which is outside and exposed to the elements including humidity from the fountains,” commented Lab.gruppen’s technical applications specialist, Thomas Vestergaard. “It’s a really tough job for the speakers to maintain their high performance levels under these conditions as they will be subject to corrosion and to softening of the cone over time.
“However, PLM already has the unique ‘load Fingerprint’ of every loudspeaker in the system saved in its LoadLibrary presets. This means that the PLMs can perform the LoadSmart load verification to ascertain system status in just 20 seconds, providing a green light for a correctly functioning driver, a yellow light for a driver that is starting to change and a red light to indicate that driver performance has dropped below acceptable parameters. If you had to test over 200 drivers individually every day, you’d never get the show started!”
SpeakerSafe real time load monitoring was among the other PLM features highlighted by Vestergaard.
