PLM+ SERIES: Technology Overview
Proven Lab.gruppen Technologies
Reliability, durability, sound quality and pure power remain the
fundamentals for any touring amplifier, and in this regard
PLM+rigorously maintains Lab.gruppen’s industry-leading reputation.
The 12K44 and 20K44 amplifiers output stages are the Lab.gruppen
patented Class TD
®
which couples the efficiency of Class D topologies
to the sonic purity of Class A/B designs. The 5K44 uses a newly
developed Class D technology design with increased efficiency and
sustained sonic performance.
Equipped with the Intercooler cooling system (12K44 and 20K44 only),
these amplifiers dissipate heat more effectively and eliminate “end of
tunnel” output device over-temperature problems. PLM+ also offers a
full suite of protection features, including thermal “show-must-go-on”
limiting, short circuit protection, excessive average current limiting,
sustained
Rational Power Management (RPM)
On top of the outstanding performance users have come to
expect from a PLM, the PLM+ series also contains Rational Power
Management (RPM), a proprietary Lab.gruppen technology that gives
system designers and techs unprecedented freedom to allocate the
output power available on each channel for optimum performance
equipment costs, reduce rack space and improve long-term energy
RPM enables the re-allocation of total output power capacity among
the four channels. For example, any channel of the 12K44 model can
supply up to 5900 W, with the provision of keeping within the total
VHF (very high frequency) protection, DC protection and voltage-and
current-clip limiting. None of the limiters introduce slow, long term
gain changes that can risk altering the balance of a tuned system.
A Breaker Emulation Limiter (BEL) prevents power interruption while
Under-Voltage Limiting (UVL) allows continued operation despite
severe voltage drops. The Regulated Switch Mode Power Supply
(R.SMPS) connects to any mains supply in
the world. The design also
incorporates power factor correction (PFC) to reduce peak current
draw from the mains. In addition, the inherent rail regulation maintains
stable rail voltages during extended bursts; extreme low-frequency
beats will not affect mid- and high-frequency headroom.
power outtake of 12000 W (up to 2000 W for the 5K44). The maximum
output channel(s) can be used for power-hungry low-frequency
systems, while the remaining output power can be allocated as
needed for the mid-frequency and high frequency drivers, providing
a smarter and more efficient way to distribute total power across any
large scale PA.
From within the CAFÉ software, RPM allows the desired power
demand to be calculated for the various loads in several different
ways. RPM then analyses the desired power in relation to the channel
and device constraints across the two PLM+ models, and guides th
system designer towards the most effective way to power the PA.

CAFÉ and RPM for Green Credentials
In addition to providing comprehensive system surveillance and
Breaker Emulation Limiter (BEL), CAFÉ also includes valuable help
CAFÉ can accurately predict, based on the true SPL and speaker
requirements of the individual loads for the given project, estimations
of average mains current draw and generated heat in BTU. With
PLM+ Series’ innovative power supply technologies (true Power
Factor Correction utilizing Current Draw Modelling) the required mains
draw is already best in class in relation to burst power output, but in
combination with the BEL the mains draw can also be safeguarded

environmental impact. It also reduces demands on UPS systems.

Lake Processing
PLM+ devices provide extraordinary input flexibility, the legendary
power of exclusive Lake processing algorithms, comprehensive
control and load monitoring via Lake Controller, and seamless integration into Dante digital audio networks with AES67 support. All PLM+
models incorporate four full-featured Lake Processing modules, with
four discrete channels of audio throughput input to output. Audio
signals are selectable from four channels of analog (with Iso-float
ground isolation), four channels via AES3 digital inputs and eight dual
redundant Dante networked inputs with AES67 support. Input signals
are individually selectable for each channel, with programmable
failover to a lower prioritized input.
The full-featured, on-board Lake processor includes group control with
any loudspeaker system. LimiterMax peak and RMS limiters set the
industry standard for loudspeaker protection and sonic transparency.
CAFÉ supplies a recommendation for optimized placement of channels

PLM+ seamlessly incorporates any of the eight available Dante input
channels into the Lake Modules, while simultaneously transmitting
eight unprocessed Dante channels onto the network. PLM+ also
supports AES67, a new open standard to easily connect devices together
and share audio.
The PLM+ Series also has the possibility to convert between AES67
and Dante, and can accordingly work as a bridge between the two
different network protocols. It can input 8 channels of AES67 and
transmit them out again as 8 Dante channels or vice versa, and in any
combination of Dante and AES67 channels.
