Load Verication and Continuous Performance Monitoring
The▸ PLM▸ 10000Q▸ incl udes▸ a▸ revolutionary▸ set▸ of▸ tools▸ for▸ fast,▸▸
accurate▸load▸veri cation▸and▸real-time▸performance▸monitoring.▸The▸
key▸to▸both▸features▸is▸the▸LoadLibrary,▸a▸comprehensive▸database▸that▸▸
provi des▸ unique▸“Fingerprints”▸(load▸characteristics)▸ for▸ each▸loud-

Lake Processing
The▸ PLM▸ 10000Q▸ contains▸ four▸ full-featured▸ Lake▸ Processing▸
modules,▸ each▸ of fering▸ precise▸ settings▸ for▸ gain,▸ delay,▸ cross-
over▸ slope,▸ equalization,▸ and▸ limiting.▸ Exclusive▸ Lake▸ Proces-▸
sing▸ algorithms▸ are▸ included▸ for▸ Raised▸ Cosine▸ Equalization,▸ linear▸
phase▸crossovers,▸LimiterMax▸loudspeaker▸protection,▸and▸Iso-Float▸
ground▸ isol ation.▸ Raised▸ Cosine▸ Equalization▸ is▸ the▸ foundation▸ for▸
the▸Lake▸Mesa▸EQ▸and▸the▸Ideal▸Graphic▸EQ,▸the▸two▸revolutionary▸

Lake Controller software
Lake▸ Controller▸ software▸ provides▸ a▸ uni ed▸ interface▸ for▸
control▸ and▸ monitoring▸ of▸ all▸ function s▸ of▸ the▸ Po wered▸ Loud-
spea ker▸ Management▸ system.▸ In▸ addition▸ to▸ controlling▸ all▸▸
parameters▸ of▸ standard▸ Lake▸ Processing▸ (therefore▸ appropriate▸ for▸
use▸with▸Dolby▸Lake▸Processors),▸all▸new▸versions▸provide▸control▸and▸
monitori ng▸of▸exclusi ve▸PL M▸features:▸digital▸input▸gain▸and▸attenua-
tion,▸and▸load▸verication▸and▸performance▸monitoring▸via▸LoadSma rt▸
and▸SpeakerSafe.
The▸ exible▸ Lake▸ C ontroller▸ softwa re▸ enviro nment▸ can▸ control▸ ex-
tensive▸ networks▸ of▸ p o wered▸ loudspeaker▸ management▸ systems▸
from▸ a▸ single▸ computer.▸ The▸ user▸ interface▸ is▸ based▸ on▸ discrete▸
processing▸mo dules,▸with▸each▸module▸assigned▸to▸power▸outputs▸
normally▸d ened▸for▸sets▸of▸band-limited▸drivers▸(e.g.▸low,▸mid,▸high,▸
subs).▸ Adjustments▸ can▸ be▸ made▸ in▸ real▸ time▸ to▸ any▸ parameter▸ of▸
any▸ module▸ on▸ the▸network.▸ Module s▸ may▸ be▸ assigned▸ to▸ groups▸
representing▸ subsystems▸ in▸ larger▸ systems,▸ such▸ as▸ main▸ arrays,▸
delays,▸and▸ lls▸ in▸an▸ arena▸system.▸Because▸ each▸module▸ can▸be▸
assigned▸to▸more▸than▸ one▸group,▸the▸Lake▸ Controller▸ can▸simulta-
neously▸address▸multiple▸groups▸for▸global▸adjustments▸ as▸ needed▸
whil e▸maintaining▸independ ent▸control▸of▸separate▸subsystems▸and▸
individu al▸components.▸
The▸ Super▸ Module▸ functionality▸ allows▸ a▸ singl e▸ on-screen▸ module▸
interface▸ to▸ control▸ output▸ channels▸ in▸ different▸ PLM▸ units.▸ For▸▸
example,▸ a▸ three-way▸ Super▸ Module▸ could▸ be▸ congured▸ using▸ a▸
high-power▸LF▸channel▸in▸ one▸PLM▸uni t▸ a long▸with▸lo wer-powered▸
MF▸and▸HF▸channels▸in▸a▸different▸unit.
The▸Lake▸Controller▸software▸is▸optimized▸for▸a▸wireless▸Tablet▸PC.▸
