PLM 10000Q Neutrik speakON connector version shown.
Power Amplier
Although based on technology in Lab.gruppen’s road-proven
FP+ Series, the amplier platform in the PLM 10000Q Powered
Loudspeaker Management system incorporates further enhancements
for even greater sustained output power. The basic output topology
remains Lab.gruppen’s patented Class TD – combining exceptional
efciency with the sonic purity of Class B designs – but with new
circuitry for greater current carrying capabilities. The Regulated Switch
Mode Power Supply (R.SMPS) delivers full power during long low-
frequency bursts and maintains stable rail voltages despite uctuating
line voltage. Additional PLM 10000Q power platform features include
extreme power density, a software-controlled bridge mode, patented
Intercooler cooling, a full suite of protection features, and a Power
Average Limiter (PAL) to prevent tripping of mains breakers.
Load Verication and Continuous Performance Monitoring
The PLM 10000Q includes 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
provides unique “Fingerprints” (load characteristics) for each
loudspeaker model in the system. Using this data and on-board DSP,
LoadSmart compares predicted response (using a brief test signal)
to the actual response, instantly identifying potential problems. When
activated, SpeakerSafe real-time performance monitoring helps the
operator avoid power compression and provides ongoing detailed
critical information about system-wide driver integrity.
Lake Processing
The PLM 10000Q contains four full-featured Lake Processing
modules, each offering precise settings for gain, delay, crossover
slope, equalization, and limiting. Exclusive Lake Processing algorithms
are included for Raised Cosine Equalization, linear phase crossovers,
LimiterMax loudspeaker protection, and Iso-Float ground isolation.
Raised Cosine Equalization is the foundation for the Lake Mesa EQ
and the Ideal Graphic EQ, the two revolutionary EQ interfaces used
by the Dolby Lake Processor. Mesa EQ offers asymmetric ltering to
match the asymmetric responses of many loudspeaker systems. The
Ideal Graphic EQ offers true sum-to-at response, so the adjustments
provide uniform boost and cut along with greater selectivity.
Lake Processing also offers both classical crossovers (selectable up
to 48 dB per octave) and linear phase crossovers. Capable of slopes
exceeding 180 dB per octave, linear phase crossovers offer greater
control to limit lobing and off-axis cancellation.
Lake Controller software
Lake Controller software provides a unied interface for control and
monitoring of all functions of the Powered Loudspeaker 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 monitoring of exclusive
PLM features: digital input gain and attenuation, and load verication
and performance monitoring via LoadSmart and SpeakerSafe.
The exible Lake Controller software environment can control
extensive networks of powered loudspeaker management systems
from a single computer. The user interface is based on discrete
processing modules, with each module assigned to power outputs
normally de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. Modules 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
simultaneously address multiple groups for global adjustments as
needed while maintaining independent control of separate subsystems
and individual components.
The Super Module functionality allows a single 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 unit along with lower-powered MF and
HF channels in a different unit.
The Lake Controller software is optimized for a wireless Tablet PC.
Operation is easy and intuitive, with the “feel” of real-time analog faders
and controls. The same Lake Controller interface can be used to
operate Dolby Lake Processors, Lake Contour, and Lake Mesa Quad
EQ processors as part of a unied system.
Another Lake Controller software feature is seamless integration with
third party
real-time sound system measurement, optimization, and
control software packages via the Lake Analyzer Bridge. Users can
measure spectrum and transferfunction and adjust system EQ at the
same time, using the same user interface.
Dante Digital Audio Network
The PLM Series Powered Loudspeaker Management systems are
equipped as standard with Dante, a self-conguring digital audio
networking solution from Audinate
®
of Australia. Based on the newest
developments in networking technology, Dante provides reliable,
sample-accurate audio distribution over Ethernet with extremely low
latency. Dante incorporates Zen
™
, an automatic device discovery and
system conguration protocol which enables PLM Series products and
other products with Dante (like Dolby Lake Processors) to nd each
other on the network and congure themselves.
